The Madness Pill: One Doctor's Quest to Understand Schizophrenia

by Justin Garson

A rollicking history of the life and work of an unheralded genius: Dr. Solomon Snyder, whose experiments with mind-altering drugs helped change the way we think about the causes and treatments of schizophrenia.

In the 1950s, the field of psychiatry had nothing to show for itself. While polio was being cured, antibiotics were being discovered, and cancer research was developing, the mental health world had no wins. Asylums were full and nobody had figured out how to fix insanity—specifically schizophrenia, the severest mental illness. Scientists became convinced that if they could engineer a pill to create madness, then they could cure it.

Centered around Solomon Snyder, the psychiatrist who ultimately did identify the madness pill, and the community of doctors and researchers he worked with, THE MADNESS PILL recounts the drug-fueled quest to cure schizophrenia. A wunderkind who started medical school at 19, Snyder worked steadily for decades to replicate the illness, ultimately finding in 1970 that amphetamines could trigger a schizophrenia-like state by flooding the brain with dopamine. Five years later, he went on to discover the dopamine receptor and proved that antipsychotic drugs work by disabling dopamine neurons. Snyder’s dopamine hypothesis inspired a generation of researchers to part ways with psychoanalysis and look for the biological basis of schizophrenia and other mental disorders.

Using first-hand research and interviews, THE MADNESS PILL is at once a raucous history and insightful portrait of a remarkable scientist who turned psychiatry into a respected science by transforming how mental illness is treated.

Solomon Snyder, or Sol, was on a quest to find a cure of schizophrenia. In order to do that he thought he needed a drug to mimic what the illness does. So he searched in psychedelics for a while, but it wasn't quite right. When speed came about and psychosis from too much speed, well, this drug was closer.

I liked the succinct way the history of psychiatry was explained. Basically two types of approach to mental health, the environmental factors which talk therapy helps; and the biological approach, which is solved with medication. The later helped move the field into a more acceptable scientific field. This book covers many of the medications that were developed.

The book was divided into the two parts: psychedelics then speed, providing a short history and some of the people that were involved in the development. The book did not solely focus on one doctor, Sol, as there was a cadre of people working in this field, but it did keep coming back to Sol’s work. The organizational method of the book made sense, but it also meant that the timeline wasn’t completely linear.

The tail end of the book became a whirlwind of different drugs all with similar sounding names. It was hard to keep that all straight, but otherwise this was a fascinating and informative book.

Early thoughts: This history should be widely known and I find it wild that after a lifetime of psychiatric treatment, I am just learning some of this material. It's difficult for me to learn this history; to see how many people like me were experimented on within the last century in the US is ...a bit unhinged.

Feeling: Brilliant; wildly uncanny.

I’m curious about: This author is managing to tell this story *without* stigmatizing mental illness. That's because he harbors no prejudice against mentally ill people, is my guess, but how right am I about that? We'll see how the rest of the book goes.

"By 1955, [...] psychiatry had split almost perfectly into two camps. In one camp there were the psychoanalysts who followed Freud and believed in the power of talk therapy. In the other were the asylum doctors who experimented on patients’ bodies in hopes of finding a cure." p24

Final thoughts: This book is cold as ice. The history is actually interesting, but I think this one delves too far into the chemistry at times. I was more interested in the history of psychiatry, and I did learn some things here. There are details included about the research process that, while relevant, create friction for the reader. To what extent depends on the reader. Please see trigger warnings. And just know that this author does not attempt to account for the myriad ethical issues involved in what is discussed here until the epilogue.

"Endorphins block physical pain. But from nature’s point of view, pain is a good thing. It’s how your body lets you know there’s something seriously wrong that needs to be fixed. [...] Yet if too little pain is bad [...] too much pain is literally debilitating. [...] That’s when the endorphins kick in. They temporarily dull the screaming rush of pain so you can continue to fight or flee." p133

What worked: 📚 good research
🥰 not grossly ableist
⚖️ Well argued, balanced

What didn’t:
🐀 so much animal suffering

Thank you to St. Martin’s Press for providing this ARC for review consideration via NetGalley. All opinions are my own.

The Madness Pill by Justin Garson is a part scientific history, part biography. Following the career path of Dr. Solomon Snyder, the book delves into some crucial discoveries in the fields of neuroscience and psychopharmacology that helped redefine the treatment of schizophrenia and other psychiatric illnesses.

The thing that makes this one of the easier science histories to read due to its concise nature. The book is relatively short, and the scope of the book is relatively narrow. The author wastes very little time delving into tangential topics. The author also is very clear in his aims that despite the career biography, this isn’t a personal biography. While Dr. Snyder’s basic biography does get mentioned, very little time is spent on his personal life. This makes a very specific, very streamlined narrative. The author is able to focus very strongly on the 50 or so odd years of research and innovation without finding the story mired in extraneous details.

I thought that the writing and language used in the story were clear and straightforward. The explanations and descriptions were technical and presumed a level of familiarity but weren’t overly technical.

Something that did impact my final feeling on the book were the epilogue and forward. While the context was certainly interesting about the personal connection, I felt like beside mentioning the side effects, it didn’t factor much into the bulk in the narrative. It was the epilogue that was really what made me feel conflicted. The author spends 200 pages talking about all the successes and innovations of this field and then levels a somewhat heavy handed critique of everything in a single chapter. It sort of felt like the author wasn’t trying to present some more food for thought but rather like they were trying to derail their own story. Sure, it’s not unusual or even a bad idea to present the counter arguments for a book, but this felt somewhat out of place. I think that this book was just too brief to have a very steep criticism in less than a chapter tacked on to the end.

For me, I’d realistically give this a 3.5/5 but feel that in light of the actual chapters of the book merit closer to a 4/5. Fascinating information, concisely written.

I won this book in a goodreads drawing.

A biography of the man who helped to create the pill used to cure schizophrenia. This caused the practice of psychiatry to turn away from talk and psychoanalysis towards drugs.

The sad part, is that as far as I can tell, niether the pills nor the talking actually work very well.

Justin Garson has a personal connection to his book The Madness Pill. He is driven to learn more about the mental health condition schizophrenia, one that his father struggled with through much of his life. Garson tracks the history of our understanding of schizophrenia primarily through the life of Solomon Snyder, a visionary who had his hands in many discoveries but kept coming back to the question on what was the biological basis for schizophrenia? The book also is a nice snapshot of the history of psychotherapy and psychopharmacology for mental health conditions. We learn about how low serotonin was discovered as a contributor to depression, which led to the development of SSRIs like prozac. We go on a journey of psychedelics and their history of how they work on the brain, which is a timeline detour considering the increased interest in psychedelic assisted therapy for conditions like PTSD and treatment resistant depression. But "Sol" keeps returning to his dopamine hypothesis for schizophrenia. The experiments he works on to prove it are fascinating. If you are interested in mental health and/or scientific discovery, you will enjoy this one.

Thank you to NetGalley and the publisher for this ALC.

Good things first: this author manages to be pretty normal about schizophrenic people. Probably because his dad was schizophrenic. And possibly because this book hardly deals with schizophrenia.

He did fail to address the misogyny present in "wandering wombs", though. I mean, if you have reading comprehension skills and basic feminist awareness, you're going to know how "wandering wombs" is misogynist as hell, but I do feel like it would have been important for the author to explicitly mention the weaponisation of madness in patriarchy.. Even if it's just a side note. Any mention please.

What I personally didn't like was that this book is more of a book on drugs, while I expected a lot more schizophrenia in this book. It was very chemistry-focused, lots of talk about different hormones and enzymes and whatever, which I simply don't know anything about. I mean, I guess it makes sense as Sol was dealing with drug development, but considering how obsessed he seems to have been with "the mystery of schizophrenia", I really would have wanted more schizophrenia here. Might be personal bias, as a schizophrenic myself, but I found that this book doesn't really address the illness itself, and just talks about like 5 different drugs and drug trials and how they work and don't work. I knew there would be discussion of Sol's work, but I still didn't expect it to be quite so... chemical. So, sadly, I was not the target audience, but my biochemistry friend might find this book really cool. I should hit her up with this rec.

I debated if I should give this a full 5-stars, or a 4.5-stars rating. Ultimately, I felt that Justin Garson's The Madness Pill: One Doctor's Quest to Understand Schizophrenia deserves all 5 stars. It was obvious that the subject matter is close to Garson's heart and was passionately written.

His interest in the subject matter comes from his personal, first-hand connection and experiences with a father who struggled with schizophrenia most of his life. Garson's research, in my opinion, was topnotch and included interviews. Garson's narrative skillfully included scientific history--specifically into the evolution of 20th century psychiatry along with the evolving science of neuroscience and mental health--and how one doctor, Dr. Solomon (Sol) Snyder (plus various peers/colleagues) quested to discover the cause for schizophrenia and sought to find its cure.

Before I go further, I would like to thank St. Martin's Press, NetGalley, and the author, Justin Garson, for providing this advance review copy (ARC) for free, and I am leaving this review voluntarily.

The Madness Pill mostly is a biography Sol, who looked at mental illness as a deficiency in the way the brain functioned rather than responding to trauma. He started his research into the subject using psychotropic drugs that included how LSD effected the brain/mind; even taking a carefully mediated "journey," to better understand LSD. Sol studied the way LSD and speed could induce psychosis, which, ironically, provided a way to understand mental illness better. Garson even teased a bit at how Richard Nixon played a bit of a role in Sol's quest--I won't spoil it, but to say, some of the historical events of the time were quite interesting to me.

Overall, I enjoyed learning more about the timeline involved with mental health and research and how this field went from psychoanalysis and progressed toward an approach that was more science based. One area that was discussed included the use of dopamine. Additionally, Garson provided a bit of history behind discovering SSRIs and SNRIs.

Garson wanted to make sure that anyone could read and understand this book, so even complex topics were understandable and engaging. Thus I highly recommend The Madness Pill to anyone with an interest in overall psychology, mental health, and, of course, schizophrenia.

Thank you to NetGalley, Macmillan Publishers, and Justin Garson for providing me with an advanced digital copy of The Madness Pill. This is my honest review.

The Madness Pill is a fascinating blend of biography, science, and history. Quite literally, this book is a true labor of love written by a son whose father lived with schizophrenia. Drawing from both personal experience and deep research, Garson crafts a compelling narrative centered on psychiatrist Dr. Solomon Snyder, whose groundbreaking discoveries helped transform modern mental health treatment.

Born in the 1930s, Snyder began his career at just nineteen with a single goal: to uncover the cause and find a treatment of schizophrenia. His lifelong dedication to this mission is both inspiring and deeply human.

As someone who regularly works with individuals affected by schizophrenia, I found this book to be empathetic and respectful toward people living with mental illness. Garson manages to balance scientific information with compassion, making complex concepts accessible and easy to digest.

I highly recommend The Madness Pill to readers interested in the history of mental health, neuroscience, or psychology. This book is for anyone looking for an approachable yet thought-provoking work of nonfiction.

What The Madness Pill by Justin Garson offers the reader is a sympathetic and approachable look into the work of psychiatrist Dr. Solomon Snyder, who spent his career attempting to understand the cause of and a cure for schizophrenia.

Thank you to the publisher for a gifted copy; all thoughts are my own.

📖 Book Review 📖 For those of you new to my page, you might not know that my husband and I met on a psychiatric ward. He was a first year intern and I was the social work intern so our early days together were treating patients, many with schizophrenia. It’s an illness that has made a lasting impact on our relationship and I think it’s probably the hardest disease to understand. Justin Garson writes a fascinating look at the history of psychiatry, focusing on the work of Solomon Snyder and his pivotal advancement in the movement to treat mental illness.

The Madness Pill is indeed a biography but sometimes truth is stranger than fiction and this one is captivating. Garson is a gifted writer, weaving in all of his research with an engaging narrative. We still have a long way to go in our understanding of the brain and how to help people diagnosed with schizophrenia but this book shines light on how far we’ve come and the need for continued advocacy and scientific developments.

Expected publication date: April 28, 2026

Justin Garson is a non-fiction author whose books focus on philosophy and science, in particular biology and neuroscience. His previous work, “Madness: A Philosophical Exploration”, introduced mental illness as a philosophical concept, whereas his new work, “The Madness Pill: One Doctor's Quest to Understand Schizophrenia” is more of a scientific examination of the development of psychiatric meds and the neurological components of mental illness, especially schizophrenia.

Garson’s father suffered from schizophrenia, which influenced Garson’s focus in his newest novel. He began to look into the scientific discoveries of Solomon Snyder, who introduced mental illness as a deficiency in brain functioning and not as a response to trauma. “Pill” starts the conversation with a focus on “recreational” drug use, such as LSD and heroin, and how Snyder realized the comparisons between drug users and schizophrenics, and how this led to his profound research.

“Pill” is scientific and neuroscience based, with a focus on psychotropic meds and their development specifically. Obviously, this relates to psychiatry and mental illness directly, but the book focuses more on the makeup of the brain itself and how various drugs came into existence and less on the mental illness component. If you are interested in books on medical science, “Pill” would be right up your alley; however if you want more of the neuropsychology angle, “Pill” can be a bit dry.

Garson focuses on Snyder’s research and influence but he covers other scientists as well, at least those who played a significant role in mental illness as we see it today. There is a brief prologue where we are introduced to Garson’s father’s struggles and how it affected and influenced young Garson, but after that, the story switches focus to the medical sciences. Garson, again, returns in the epilogue to talk about his personal feelings on psychotropic medications and their impact on his father and others who suffer, which I found profoundly impactful and emotional, even though his personal opinions on medication seems to go against the very premise of this story.

“Pill” is a scientific non-fiction story on the progression of mental health treatments, attitudes and, specifically, medication, which have changed over time and how much progress we still need to make. If you have an interest in how medicines are discovered, approved and distributed to the public, then “Pill” will provide some interesting insight.

Thank you, NetGalley, for granting me a free digital copy of this audiobook in exchange for an honest review.

Schizophrenia is one of, if not the worst psychiatric disorders out there, plaguing its patients with hallucinations, delusions, paranoia and, in some extreme cases, even rendering them catatonic. It's also one of the most "cinematic" disorders: hearing voices is a telltale sign of madness in storytelling (oftentimes intertwined with tortured genius), and has long captured audience's imaginations. All this perfectly explains both why scientists would be driven to study schizophrenia, and why the morbidly curious would be drawn to a book like The Madness Pill: One Doctor's Quest to Understand Schizophrenia. The catch is that we really don't understand schizophrenia very well, even today, which presents an issue not only for real-life patients, but also for the resolution of this book.

Very little time is allocated to the people struggling with schizophrenia in The Madness Pill. Even the symptoms of the condition are treated more like background information than as a focal point of the research. Instead, the first half of the book focuses primarily on the LSD experiments Dr. Sol Snyder and his associates ran on themselves and others, believing that the psychedelic simulated similar effects to schizophrenia, and therefore held the key to understanding (and hopefully treating and curing) it. The ethics of these experiments are a bit foggy--the students who participated in them would have been volunteers, but given what we know now about the effect psychedelics can have on some people, this comes across as reckless at best. Garson appears to find no issue with it, and even casts the growing public disapproval for LSD in the late-1960s as akin to a moral panic.

As it turns out, LSD didn't truly replicate the effects of schizophrenia after all. Speed (amphetamines) was a better substitute, albeit even more dangerous, and Snyder and co. were able to gleam much information from studying it without ever reaching a firm explanation for schizophrenia's origins. The science can be difficult to follow, and after arguing in favor of a biological explanation for schizophrenia for the entire book, Garson abruptly switches lanes in the last chapter and suggests that it might be sociological instead. There's no mention of schizophrenia's inheritability, or if certain demographics are more susceptible to developing it. Given the heavy focus on drug experiments, the complete absence of marijuana--which studies have increasingly shown has a direct link to schizophrenia, at least among men--is also a noticeable blind spot. Dr. Snyder's work surely helped many people, but The Madness Pill feels incomplete, both because of how far there still is to go in treating this horrifying illness, and because of all the crucial information that was left on the cutting room floor.

[Steve's Book Stuff · Rating 4 out of 5]

Justin Garson’s father suffered from schizophrenia. He recounts his father’s madness, and his experience with psychiatry in the introduction to The Madness Pill . At first, in the 1970s his treatment was therapy sessions. But when his illness came back in the 1980s pills became his treatment regimen. In between his first bout with mental illness and his second, psychiatry had undergone a revolution. And one of the reasons why was the work of Dr. Solomon Snyder.

Garson’s new book centers itself on the long career of Dr. Snyder. Other scientists make their appearances as well, especially as the book enters the 1960s, but Snyder was the one whose discoveries around dopamine, dopamine receptors in the brain, and their link to schizophrenia, revolutionized psychiatry.

Born in 1938, Snyder graduated from medical school at Georgetown University in DC, specializing in psychiatry. From there he spent time at Kaiser Hospital in San Francisco before landing a role as research assistant to Julius Axelrod at the National Institutes of Health. It was there where his love of laboratory science and scientific research took off. He spent decades searching for the biological roots of schizophrenia.

Garson’s book is part biography and part scientific history, and he has done an excellent job of blending the personal stories with the scientific work. Some of the experiments that Snyder and his peers conducted in the 1960s with psychedelic drugs, including LSD with themselves as the guinea pigs, shows both their dedication to the search for a solution to complex scientific problems, and the naiveite of the times.

This book has a lot in common with Off the Scales, Aimee Donnellan’s book about Ozempic and the discovery of GLP-1 drugs that I reviewed last November. Donnellan acknowledged in her book that obesity has both physical and psychological origins. Garson also acknowledges that the understanding of the chemical nature of mental illness, that Dr. Snyder played such a large role in uncovering, has led to the discovery of drugs much more capable of treating their effects. But there is a growing recognition that drugs cannot replace psychoanalysis but rather must supplement it.

This is an informative and interesting history of the late-twentieth century discoveries about the biology of schizophrenia. Read it for a window into the history of mental illness, psychiatry and our understanding of how the brain works.

Justin Garson provides an intriguing look into the study of schizophrenia in his book The Madness Pill. The quest to determine what caused schizophrenia led scientists and doctors to explore drugs and whether or not they could recreate the symptoms of schizophrenia. This book focuses on two drugs: LSD and Speed.

When covering scientific topics, it is easy to fall into heavy jargon use and dry explanations of all the gritty details. Garson avoids all of that with clear language and a closer look at the person doing the investigation, Solomon Snyder, rather than the investigation itself. That is not to say that the book does not cover the details of the drugs or the mental illness. Garson has a way with words that weaves the two together in fascinating narrative that keeps readers engaged. I never found myself getting bored while reading this book. Each chapter contained interesting details, and I was excited to keep going. Even for someone who has never been particularly interested in the topic, this book kept me engaged.

This book is very well written and well organized. It is split into two parts, each covering one of the ‘madness pills.’ Both sections are thoroughly researched and could easily stand alone as an examination into the particular drug and its potential connection to the symptoms of schizophrenia, but Garson effortlessly blends the two together to show a clear process of the study of the drugs. Garson also does a good job with his examination of Solomon Snyder and how he fit into the larger study of drugs and schizophrenia in the mid twentieth century.

If you are interested in the history of the study of schizophrenia and doctor’s determination to recreate the symptoms of the mental illness than this is the book for you. It is also a great book to pick up if you are itching to learn something new. It does not require any previous knowledge of the subject and the writing it inclusive enough that anyone can pick up the book and easily follow along.

It’s complicated: neuroscientists exploring the complex biological, chemical and functional mechanisms of the brain. Yet, it’s written in a simplified version to make it easier for the average person to understand.

Justin Garson started with his dad’s health predicament. He had a distinguished career as a lawyer in DC under President Nixon and then he was overpowered with symptoms that made it impossible to work. In 1973, his dad was diagnosed with paranoid schizophrenia. He was prescribed with various pills at a psychiatric hospital in the DC area that made him appear somber.

Garson decided to take a deep dive into the progress made over the years. He revealed the result of conversations with neuroscientist Solomon Halbert Snyder who now lives in a nursing home after years of an outstanding career developing better ways of treating patients with schizophrenia. Synder gave him an outline of what led up to the “madness pill.”

The book provided a considerable amount of research. One part focused on the brain area with the use of LSD (how the brain sees images) and how it compared with schizophrenia (as one hears voices). One theory from a scientist was that the brain was flooded with too much dopamine. It outlined the difficult work of many scientists who were competing for funding and results.

Garson said now most mental disorders are treated with prescribed drugs. He mentioned the books that have been written over the years. I wish he took it one step further to explore the current AI-driven research. This book did a decent job describing the history and yet, there’s so much more to learn.

In The Madness Pill, Justin Garson unfolds the life and achievement of Solomon Snyder, a psychiatrist whose mission to understand and treat schizophrenia resulted in leaps and bounds being made in the study of psycho-pharmaceuticals.

I always find non-fiction kind of hard to review, but this was very solid overall. Science history nonfiction is usually what I go for when I want to read nonfiction and I've read similar books so this is familiar territory for me. Ultimately, it was informative but not particularly exciting. It was similar to Poisoner in Chief by Stephen Kinzer, both because they had some overlap in content and also because I had similar issues with both books. They both discuss pretty exciting subjects—basically the discovery of medication based mental-health treat and the CIA's experimentation with LSD respectively—but the actually book ends up being kind of dull. It's a real skill to spin a non-fiction story into something that feels like a fictional narrative and is therefore engaging and emotional, but I don't think The Madness Pill quite manages it. The story departs from Snyder so much that it's difficult to get invested in him, and there isn't much enchantment around his discoveries. I think the book could have really benefitted from some personal contributions from the author, because the few moments where Garson opens up about his own experiences with mental illness in his family are some of the highlights of the book, but they are few and far between.

It does the job and Garson did a great job narrating, but I think a lot more could have been done with this story.

I find it interesting that the science-oriented books that I have read that are written by authors who have a personal stake in the subject matter end up being some of the best books on the subject. “The Madness Pill: One Doctor's Quest to Understand Schizophrenia” by Justin Garson is one such book.

His father had suffered from schizophrenia, and as with many diseases, the affliction doesn’t just affect the sufferer but the family as well. Consequently, the author was interested in schizophrenia as a disease because, during the time of his father’s affliction, the treatment of schizophrenia went from talk therapy, which wasn’t all that effective, to medications that had a profound impact on the sufferer.

In fact, the field of psychiatry began to gain respect in the medical community because of the ability to “treat” schizophrenia and other conditions. This shift in the treatment could be traced back to a seminal paper on the discovery of the dopamine receptor and its effect on schizophrenia.

That paper was “The Dopamine Hypothesis of Schizophrenia” by Solomon H. Snyder and it started psychiatry’s biological revolution.

Author Justin Garson book “The Madness Pill: One Doctor's Quest to Understand Schizophrenia” is a story about Dr. Solomon H. Snyder’s quest to find the biological cause of schizophrenia.

But first, a brief explanation of what “schizophrenia” is. From Wikipedia: “The word schizophrenia (“splitting of the mind”) is Modern Latin, derived from the Greek “schizein” (Ancient Greek: “to split”) and “phrēn” (Ancient Greek: “mind”). Its use was intended to describe the separation of function between personality, thinking, memory, and perception.”

When I was growing up in the Sixties and Seventies, a common mistake was to use the definition of schizophrenia to refer to a person who had multiple personalities, popularized by the 1957 movie “The Three Faces of Eve.” Now schizophrenia is no longer identified as such and anyone with multiple personalities is now diagnosed as having Dissociative Identity Disorder (DID).

I found “The Madness Pill: One Doctor's Quest to Understand Schizophrenia” a compelling read and, in fact, many times I found myself reading past my designated stop time, it was that superbly written.

I especially like the way that the author was able to segue into diverse topics that were peripherally related to the topic, never losing the thread of the discussion or topic. I also like the way he wrote about the other scientists who worked with Dr. Snyder, giving just enough background to understand their place in the overall subject.

This book will be of interest to anyone interested in mental illness, specifically schizophrenia, as well as the “hippie” drug culture of the Sixties.

5/5

How did we go from thinking of schizophrenia as a purely "mental" pathology to a dysfunction of neurotransmitters? Garson chronicles the path from the origins of this disease, starting from a time when we thought the cure was talk therapy alone to the modern age where there are dozens of drugs aimed at biological targets. As someone with no knowledge of this history, it was fascinating to see the rapid shift in the culture of psychiatry. Garson focuses on one notable figure, Dr. Solomon Snyder, a man credited with a large part of our understanding about the biological basis of schizophrenia (and also apparently a pretty good classical guitarist).

I learned a lot from this book, something that rather surprised me. Garson didn't shy away from going in-depth as far as the science of medications, but he also devoted ample time to describing the political/social environment that pivotal discoveries were occurring in. I think Garson's conclusions in the epilogue were thorough and insightful, but I also wonder if they're not a bit at odds with the message of the book. It almost feels as though he spends so long dedicated to the biological basis of disease only to trivialize it in his final discussion. While I recognize that this is a call for more more nuanced care, and considering the dangers of a purely biologic view of psychiatric disorders, it seems to detract from the discoveries he spends an entire book describing. That being said, his views are intriguing; I would read any book he decided to author exploring the sociological aspects of schizophrenia in todays society.

I received an advance copy of THE MADNESS PILL: ONE DOCTOR'S QUEST TO UNDERSTAND SCHIZOPHRENIA by Justin Garson from Macmillan Audio!

Publication Date: 4/28/2026
Rating: 4 / 5

THE MADNESS PILL is a nonfiction looking at the history of psychiatry's attempts to understand schizophrenia with a focus on the work of psychiatrist Solomon Snyder. Seeing medicine come leaps and bounds in regards to other diseases, scientists took on the quest for engineering a pill to create madness in the hopes of also figuring out how to heal it.

The quest to cure schizophrenia is a story full of drugs that created similar symptoms. In the 70s, Dr. Snyder sought to create schizophrenia type symptoms, ultimately finding that amphetamines succeeded in this regard by flooding the brain with dopamine. This in turn led to anti-psychotic drugs which inhibited the brain's dopamine neurons.

As someone who works for a nonprofit working with adults with mental illnesses, this book instantly appealed to me and I found it to be very informative. It did a lot to discuss the similarities between drug use and mental illness. It also went into a lot of history around the availability of amphetamines, its uses and addictions in history.

From a past where talk alone was meant to get those dealing with mental illnesses to be cured to the very important recognition that mental illness is a physical and biological illness. This is still a reality that some still challenge today. Over my years working in mental health, I have seen shifts and improvements in the medications available, so I found it very interesting to get some of this far back history of where it all started!

With "The Madness Pill," Justin Garson has written a fascinating biography of Dr. Solomon Snyder and his search for the cause of and cure for schizophrenia. Garson's writing is conversational, compelling, and driven by a personal interest in the topic (Garson's father had schizophrenic disorder). He combines an objective philosophical point of view with rigorous primary and secondary research—codified in an extensive list of references—of Snyder’s life and research.

I struggled to put the book down. The relationships between the visionary scientists, the mysteries of psychiatric biology they were trying to solve, and the challenges they faced are woven together like a scientific thriller. Alas, the book poses more questions than answers, since we still don't have a specific cause and cure for schizophrenia nor for many other mental disorders. In thinking about the ever-increasing use of drugs to cure mental disorders, I couldn't help but wonder if the scales have tipped too far from psychiatry's origins of psychoanalysis to psychopharmacy. The Epilogue addressed many of my thoughts and ponders a solution that is not either/or but rather both.

For readers interested in the history and future of diagnosis and treating mental disorders, "The Madness Pill" is an informative and thought-provoking book—but don't skip the Epilogue.

I received this book courtesy of the Goodreads First Reads program for the purpose of a fair and honest review.

Overview: Schizophrenia has been a thorn in the side of mankind for quite a while now. But how did psychiatry go from Freud and the asylums to hide the mad away, to finding a group of medications that can work for those who have to deal with the symptoms of madness? That's where Doctor Solomon Snyder comes in. How did he come to understand how parts of schizophrenia work? Let's find out.

Dislikes: This does lean rather heavily into some scientific terms. That's not a bad thing per se, it just makes for dry reading at a time.

Likes: The effort Dr. Snyder went through just to discover part of how schizophrenia works. It takes a big person to admit that perhaps the plan to make it easier to communicate with those who have schizophrenia, may have had unforeseen consequences.

Dr. Snyder seems to have been quite the musician. I don't blame him for finding something else to work at.

Few of us today realize what exactly added the regulations on scientific studies. This book will tell you. None of these 'volunteers' sound like they understood what was going on, or what they were agreeing to.

Conclusion: This was a fascinating book. If you like biographies or medical history, then this book is for you. Enjoy the read.

The Madness Pill is a fascinating biography of Dr. Solomon Snyder, detailing his quest to discover the cause of schizophrenia.

This is a fairly quick read at less than 200 pages of actual text, but provides a wealth of information. The book is in third person, so as a reader, the purpose isn’t to get to know Sol as a person outside of his research. Instead, the thesis of this work is to provide a timeline and life and history of Sol, his research, and how that research contributed to psychiatry and biological neuroscience.

It’s a very successful and well-researched book. While it’s not what I would traditionally rate 5 stars even for a non fiction work, I ultimately stopped waffling on whether I should round down to a 4 or up to a 5 because I think that’s this book delivers exactly what it sets out to and does so in a remarkably interesting way.

For people interested in psychology, psychiatry, or in schizophrenia research, this is an empathetic and interesting biography that has enough technical meat to interest someone with academic knowledge of those topics, and yet is explained well enough to allow for more novice readers to enjoy the book as well.

Thank you to St. Martin’s Press for providing this ARC for review consideration via NetGalley. All opinions are my own.

If you've ever wondered how psychiatry went from guesswork to genuine science, The Madness Pill offers a fascinating answer. Garson traces the unlikely path through mid-century medicine, when researchers — desperate for a foothold against schizophrenia — decided the best way to cure madness was to first engineer it in a lab.

At the center of the story is Solomon Snyder, a prodigy who entered medical school at 19 and spent decades quietly reshaping our understanding of the brain. His discovery that amphetamines could mimic schizophrenia by flooding the brain with dopamine, and later his identification of the dopamine receptor itself, gave psychiatry something it had long lacked: a biological foundation to stand on.

What makes the book work is how readable Garson keeps it. The history of failed treatments and institutional neglect could easily feel heavy, but instead the narrative moves with real momentum. I came away with a much richer understanding of how far the field has come.

A genuinely engaging read for anyone curious about the history of medicine, mental health, or the strange, sometimes reckless ingenuity that drives scientific discovery.

Thanks to NetGalley and the publisher for an ARC in exchange for an honest review.

Growing up with a mother who works in the field of psychology, I inherited her interest in the subject. This title instantly caught my attention. I've never read deeply into the medical side of things, so I was excited to branch out.

This book is mainly a biography of Dr. Solomon Snyder and his studies to find a pill that not only helps schizophrenic patients, but one replicates the experience of a psychotic episode. It's also a general history of the pharmaceutical approaches to various mental illnesses. At the beginning and the end, the author inserts his personal experiences with schizophrenia through his father, adding a personal touch.

I found the book interesting, but by the end, I wasn't entirely sure if the author was for or against Dr. Snyder's research. I suppose it can be thought of as presenting the pros and cons, but I would have liked that to be clearer. I liked that there was discussion beyond schizophrenia included as well, so much connecting when you see it written down, and the research felt solid.

Extra content warning: There are graphic depictions of animal experimentation.

Thanks to St. Martin's Press and NetGalley for providing me with a free digital ARC of the book!

3.5 ⭐️ rounded up

I thought this audiobook was very well narrated, and was pleased to see that the author himself was the narrator which is perhaps why it seemed to flow with such smoothness.

I enjoyed learning the history and biography sort to speak of Dr. Soloman Snyder and the history of treating schizophrenia.

While I was very impressed by the amount of detail and history which was included, there were some sections that I just wasn’t so prepared for (i.e., talking about scooping out rat brains, blending them then, and injecting them with drugs) which were quite a shock to me. I also felt that this was more a medical history type of read, and that the number of details at times became overwhelming to follow to someone who does not know the intricacies of this particular field.

The last chapter was probably my favorite, to be honest, talking about today’s treatment and diagnoses, stigmas, etc. and more about the author’s personal tie to this subject as it relates to his father. Overall, though, I thought it was a very interesting read.

Thank you to NetGalley & Macmillan Audio for this advanced listener’s copy. All thoughts and opinions are my own and my review is left voluntarily.

I received this book from Net Galley in exchange for a review.

Sol Snyder is a doctor and researcher who sought to recreate “madness” initially with LSD and then amphetamines. His theory was that if you could recreate the symptoms of schizophrenia in a controlled environment, you could then potentially understand the mechanisms working to cause it.

This book details his research journey and some of the successes and failures along the way. I didn’t have much background knowledge going into this book and I found it to be easy to understand and interesting. There is an informal quality to the tone and writing that make it feel like you’re reading a correspondence from a friend. The author’s father was diagnosed with schizophrenia, so there is a care taken and there isn’t any judgement for the behaviors exhibited by the patients discussed throughout the book.

If you are looking for a biography on someone who played a role in shifting the focus of psychiatry from talk therapy to medication, interested in the history of schizophrenia research, or neuroscience more generally I think this is an option worth pursuing. It is not overly technical and gives an overview of the topics mentioned above. I appreciated learning about Dr. Snyder and the research that made up his career. Especially given how much that research and his dopamine hypothesis have impacted the trajectory of modern psychiatry.

[Jeremy Reppy · Rating 4 out of 5]

This was a fascinating book. I enjoyed learning about the history of the study of and treatment for schizophrenia and other mental illnesses; the various theories for what caused schizophrenia; the medication trials; the professionalization of psychiatry; the way certain doctors and scientists were able to take existing research and knowledge and see connections or new insights; how chemicals designed for non-medicinal purposes were able to be repurposed for medical uses, etc. Some of the experiments that were tried were pretty wild — experiments that would never be allowed today. I appreciated that the author used the epilogue to highlight the downsides of the medicalization of mental illness, especially that while knowing there is a biological component to mental illness provides a sense of comfort to those with mental illness (there is a reason I am like this), it also creates a belief that the mental illness is something that can possibly be managed but never overcome. For some people that is certainly true. But for people whose symptoms are heavily tied to life stressors, mental illness is not necessarily permanent.
