Findings show changes in specific regions of the brain

No evidence observed for causal effect of stimulant prescription on subsequent psychotic experiences when applying doubly robust estimation

Elevated Aβ status disclosure linked to modest decrease in anxiety and motivation to change lifestyle

Increased global efficiency, as well as decreased characteristic path length and altered nodal centralities, seen on functional MRI

Associations seen between less short wave sleep and rapid eye movement sleep with smaller inferior parietal region volumes

Anterior insula, medial prefrontal cortex, and dorsolateral prefrontal cortex associated with history of heavy use

In longitudinal analysis, epilepsy population had elevated risk for neurological diseases and psychiatric disorders

Most associations, including thinner prefrontal cortex and greater whole brain volume, precede substance use initiation

Increased risk seen for a composite of stroke, dementia, late-life depression, which persisted for sexual, gender minorities separately

Perceived chronic traumatic encephalopathy doubles risk for suicidality
