TL;DR: The findings of this study suggest that elderly individuals who commit suicide represent a heterogeneous group with regard to mental disorders, implying a need for differentiated prevention strategies.

TL;DR: Serious viral CNS infections during childhood appear to be associated with the later development of schizophrenia and nonaffective psychoses, and the association with specific viruses suggests that the risk is related to infectious agents with a propensity to invade the brain parenchyma.

TL;DR: An impairment of late neurodevelopment affecting the acquisition of verbal skills in adolescent boys and young men who later develop psychosis is suggested, and a relative decline in verbal ability between ages 13 and 18 years is a stronger predictor of psychosis than verbal ability at age 18 years alone.

TL;DR: Good performance in secondary (age 16) and upper secondary school is associated with a reduced risk of suicide in men but not women, and this protective effect is not seen amongst those who develop severe psychiatric illness.

TL;DR: A history of an alcohol use disorder conferred an increased risk of admission with a diagnosis of Parkinson’s disease in both women and men, and the risk seemed higher at lower ages of first admission with Parkinson's disease.
