A recent study stated that violent crimes are not committed by people with mental illness as even ordinary people can commit them. The chief cause for this was substance abuse.

People who were suffering from bipolar disorder were compared with those who were ordinary when it came to crimes like robbery and assault.

It was observed by researchers that higher risk of violence was associated with bipolar disorder but drug and alcohol abuse were mainly responsible for these happenings and even a person who was ordinary could do these under alcohol and drug influence.

In individuals who had no violence history and were with bipolar disorder there was no significantly increased risk of violence in.

It is being thought that these conclusions would lead to negating the assumption that people who have bipolar disorder are violent.

They also stated that these conclusions should be taken into account when individuals with bipolar disorders are treated who are under alcohol and drug influence and during the risk assessment of such people.

Researchers from Karolinska Institutet, Stockholm, and Oxford University, carried out the study.
