The problem is that the makeup of women and men’s bodies is different. For example, a woman having a heart attack doesn’t present with the same symptoms as a man. Instead of chest pain, women typically have flu-like symptoms such as sweating and nausea. And that means they’re seven times more likely to be misdiagnosed and sent home, mid-heart attack.
Women metabolize medicine differently to men as well. Researchers found that the recommended daily dose of the sleeping pill Ambien is actually harmful to women because – you guessed it – the dose was tested on men.
The medical establishment has long treated women’s health with what’s known as “bikini medicine”: seeing women as different in terms of their reproductive organs, but otherwise physiologically identical to men. But that overlooks one vital area of difference: the brain.
Women are twice as likely as men to experience depression or anxiety. They experience four times as many migraines and are three times more at risk of autoimmune diseases like multiple sclerosis. Most worrying of all, two out of three Alzheimer’s patients are women. In fact, a woman of 45 has a one in five chance of developing the disease over the course of her life. A man of the same age has only a one in ten chance.

Hormonal transitions like menopause radically affect brain health.
If you’ve experienced the ups and downs of premenstrual syndrome, or PMS, you won’t be surprised to hear that hormones affect your brain. You may be surprised to hear just how much.
The hormone with the most influence is estrogen. Known as the “master regulator,” estrogen affects just about every important brain function. It helps with the production of energy, keeps cells healthy and sparks activity in the parts of your brain responsible for memory and attention.
It also helps protect your brain by boosting your immune system and keeps your mood on an even keel by helping the brain release endorphins. Which is why it’s so devastating when women hit menopause and their estrogen levels fall off a cliff.
Menopause happens when a woman has her last menstrual period and is no longer fertile – usually around her forties or fifties – although a woman who’s had a hysterectomy will experience menopause sooner.
Apart from the typical symptoms like hot flashes, the drop in estrogen has an enormous impact on the brain. Many women find they struggle with depression and anxiety. Some even experience bipolar or schizophrenic symptoms for the first time. On top of that, menopause makes women more susceptible to heart disease, obesity, and diabetes.
Studies of brains pre- and post-menopause show that activity decreases as estrogen levels drop. At the same time, a key indicator of Alzheimer’s disease – the level of amyloid plaques in the brain – increases. Memory centers in the brain also shrink. It turns out that menopause increases the risk of dementia in 80 percent of women.
It can seem like Alzheimer’s comes on suddenly, but the disease is decades in the making. While the clearest symptoms may only be visible in old age, the groundwork is laid when we’re young. For many women, menopause is when it begins.
So, what does this mean? That you have a hormonal target on your back that you just have to accept? Emphatically, no. You need to know about the implications of these hormonal transitions and how to deal with them.
With the right preventive strategies, the effects of menopause can be managed so your brain stays healthy through menopause and beyond.

Alzheimer’s isn’t a natural part of getting older or necessarily hereditary – it’s usually preventable.

Eating a balanced, nutritious diet is the way to optimize your brain health.
If you’ve ever found yourself reaching for a cup of coffee when you’re sleepy, you’ll know that what you eat and drink directly affects your brain.
Our minds depend on food to replenish energy and to help essential functions. If you want to keep your brain healthy, diet is the first thing you need to work on.
Popular wisdom about what we should eat is always changing. In the early 1990s, low-fat diets were gospel; today high-fat “keto” diets are all the rage. The truth is, no extreme diet is healthy for your brain. Instead, focus on the quality of the food you eat.
Some fats are bad for you; others are essential. Take trans fats. They’re highly processed and toxic for your body in any amount. On the flipside, the unsaturated fats found in avocados, nuts, and fish help your heart and brain to flourish, especially if you eat them every day.
The same is true of carbohydrates. Foods which are high in sugar, like white bread, pasta, and cakes, cause your blood sugar to spike and then crash, making it hard for your body to regulate energy. But complex carbs like those found in vegetables, brown rice, and quinoa are high in fiber that balances estrogen and the sugar levels in your bloodstream.
Chickpeas, flaxseeds, and apricots are all good foods to help regulate your estrogen levels. And if you want to actively boost your brain’s health, then you should be regularly eating superfoods full of antioxidants. At mealtimes, half your plate should be stacked with vegetables – the more colorful the better.
To support your body in processing all these nutrients, you also need to optimize the good bacteria in your gut. That means eating lots of prebiotics like onions, bananas, and garlic that act as a kind of “fertilizer,” as well as probiotics found in food like yogurt.
But even with the best diet you might sometimes need extra support. If you’re feeling down or unusually tired, ask your doctor to check your level of B vitamins and Omega 3 fatty acids, which are essential for your mental and emotional wellbeing and brain health.
By eating a balanced diet of high-quality foods and supplementing where you need to, you’ll allow your body – and brain – to flourish.
