This is a compilation of articles from Scientific American over the 5 years up to its publication in 2021, that provides a good survey of the latest scientific developments in our understanding of depression and anxiety. There are quite a lot of nuggets of knowledge including:
- It is not true that depression is caused by a chemical imbalance in the brain. This is a theory pushed by the pharmaceutical companies, but there is no conclusive evidence.
- It is quite likely that depression is caused by situational factors. Strong feelings of stress and shame are also likely to be causal factors.
- Caregivers of mentally or medically unwell family members are also prone to becoming depressed
- Post-partum and para-natal anxiety is just as prevalent but much less known than depression. It can result in desire to self-harm or harm the infant.
- Exercise is very good for mental health. So are the right diets including Mediterranean, Okinawan and Nordic diets.
- Watching a lot of TV, sedentary lifestyle and western diets like fast food all increase the likelihood of depression.
- Depression could actually be an adaptation to shut out distractions and allow the mind to focus on complex problems, rather than an illness.
There are also quite a few articles about possible treatments including pharmaceuticals, electric shocks, apps, psychedelics, etc all of which have some record of success but there is no sure-fire solution that works for everyone.
Overall, a good introduction to the topic of depression and anxiety because the curated articles cover a broad range of the associated issues.
