Researchers from the Danish psychiatry research-project iPSYCH have contributed to identify 33 new genetic variants which, as it turns out, play a role in bipolar disorder. To achieve this, they have examined DNA profiles from 413,000 people.

Almost half of the parents who have children together with a parent with schizophrenia or bipolar disorder, are themselves burdened by psychological issues. This can affect family life and the children. This is shown in the research result from the major Danish psychiatry project iPSYCH.

New research shows that patients who have had contact with the hospital due to serious glandular disease have a greater risk of subsequently developing depression. The study from iPSYCH is the largest yet to show a correlation between glandular fever and depression.

An international collaboration headed by researchers from iPSYCH has found genetic variants that increase the risk of aggression in children with ADHD. In the same study, the researchers also discovered that the genetics which increase aggression in some children with ADHD, are the same genetics that affect aggression in children without a diagnosis.

The results of a new Danish study by researchers from iPSYCH show that the amount of green space surrounding children's homes has influence for the risk of developing ADHD. The study is so far the largest of its kind.
