BBC NEWS | Health | Suicide linked to brain changes: "The brains of people who commit suicide are chemically different to those who die from other causes, a Canadian study has suggested.

Researchers analysed brain tissue from 20 dead people and, in those who killed themselves, they found a higher rate of a process that affects behaviour.

Writing in Biological Psychiatry, they said it appeared environmental factors played a part in the changes."
