It comes as no surprise to anyone working in mental health, that mental ill-health is more often caused by experience than by biology or genes. Unfortunately, it seems, the funding just isn’t available for woolly stuff like emotions and behaviour. Science is sexy and it’s easier to get research funding for things like brain chemistry and genetics.
There’s also another area of confusion that contributes to mental health being constantly under-funded. Studying the causes is all very well, but what is really needed are effective treatments which produce positive outcomes for sufferers.
Knowing about the cause of a problem can be useful in correcting the social and other problems that lead to mental ill-health. But, it’s not essential or even necessary when treating, say, depression or anxiety, to understand the cause. The urgency is to treat the effects, which means tackling the symptoms to relieve the suffering.
