Key Facts: Adults with ADHD face statistically higher risks for cardiovascular diseases, including hypertension and arterial disorders. Impulsivity serves as a behavioral gateway to health risks like substance misuse, binge eating, and physical inactivity. Preterm birth is a significant predictor of ADHD severity due to disruptions in early fetal brain glucose metabolism and blood flow. Stimulant medications improve health outcomes by reducing risky behaviors, despite potential side effects like elevated heart rate. Early intervention in childhood is a primary preventive measure against the cascade of long-term adult health complications.
