Experts: Psychotic disorders in youth and young adults 

While overall rates of psychosis in Canada appear stable, there has been a sharp increase in diagnoses among adolescents and young adults, and they are receiving diagnoses at younger ages than did members of older generations, according to a new study published in the Canadian Medical Association Journal. 

Researchers suggest the trend may reflect a mix of factors, including improved early diagnosis and treatment and increasing consumption of psychoactive substances.
