Addressing the real causes of mental pain

I WOULD like to respond to Jaime Hyland’s letter (Irish Examiner, October 25) in which my view that genetics do not play a significant role in behaviour or in ‘mental illness’ was criticised.

The scientific evidence in support of Jaime’s view is very sketchy indeed and far from conclusive.

I would acknowledge though that some people may have a genetic predisposition towards certain behavioural or emotional problems.
