Insomnia linked to psychosis in the young

Young people who experience insomnia symptoms have almost a threefold increased risk of psychosis onset compared with their peers, an Australian study suggests.
The findings also indicate that adolescents and young adults with a history of sleep-wake disturbances — such as poor-quality sleep, oversleeping or daytime fatigue — have a 1.5-2.5 greater relative risk of developing mood disorders, such as bipolar or depression.
