Summer births linked to schizophrenia

Young people who develop a severe form of schizophrenia are strikingly likely to have been born in the summer, according to data collected in six countries. Symptoms of the condition, sometimes referred to as deficit schizophrenia, include a lack of emotion, apathy, and an inability to handle social and work situations. In contrast, nondeficit schizophrenia typically includes intense emotions and suicidal thoughts.
