A recent study reinforces this view, says David Bakish, a psychiatrist at the Royal Ottawa Hospital. David Bakish studied patients who could not stop thinking about killing themselves and who had a family history of suicide.

He was surprised at his discovery that the patients' brain cells had changed in an apparent attempt to make up for a lower than normal amount of a common brain chemical. This means that the desperate acts of committing suicide might be due to a genetic mutation. If researches have proved that this is true, then perhaps many people can then avoid the fate of killing themselves in the end.

Suicide is sometimes associated with mental illness such as schizophrenia or bipolar disorder, where the cases of suicide can be more common than in people without a history of mental illness.
