Stress and trauma raise risk for neurodegenerative disease

Key clinical point: Individuals exposed to stress and trauma had a higher risk of developing neurodegenerative diseases compared with unexposed controls.

Study details: The data come from a population-matched and sibling cohort study including 61,748 exposed and 595,335 unexposed individuals in Sweden.

Disclosures: The researchers had no financial conflicts to disclose.
