Symptoms of Attention-Deficit/Hyperactivity Disorder in Adults with Restless Legs Syndrome

Abstract

ADHD symptoms are more common in RLS patients than in patients with insomnia or controls. RLS leg discomfort or poor quality of sleep may theoretically lead to hyperactivity and lack of concentration. Alternatively, RLS and ADHD may be part of a single symptom complex, and dopaminergic deficiency may play a role in both disorders.
