One, this is a mostly unsupported phrase used by therapists which may be comforting to patients but isn't actually backed by neuroscience. The best that can be said is that drugs which affect the brain help some people with diagnosed mental illness. The chemical mechanisms for most mental illnesses are not known or barely hinted at.
>Also, this presupposes that by the time you are old enough to experience the world your brain isn't "malleable enough" to handle it which seems unlikely unless you're really sheltered from the vast majority of the world until your late 20s.
This seems to be parroting the "your brain doesn't finish developing until 25 (or whatever)" which has gone around quite a distance as a meme but has no scientific basis.
There are many development windows for many different things, some known better than others. A 20 year old does not have the same language acquisition skills as a 3 year old. My eyes work a little funny because I was myopic at birth and some control systems didn't develop between birth and 6 months and that window is just permanently closed. Most things remain at least a little malleable and some much more than others but this does not mean that there aren't developmental periods at a young age which aren't very important.
Two, many chemical feedback systems are trained in early life. The "chemical imbalance" could be exactly this, childhood experiences not matching adult ones and as a result brain chemistry responds poorly to adult stimuli.
