Periodic Limb Movement Disorder (PLMD) is a sleep disorder characterized by repetitive limb movements during sleep, often leading to sleep disturbances and daytime fatigue. These movements are typically stereotyped and can involve various muscle groups. PLMD is frequently associated with other conditions such as Restless Legs Syndrome (RLS) and Attention-Deficit Hyperactivity Disorder (ADHD).

Diagnosis and Misdiagnosis:
PLMD is a sleep disorder marked by repetitive limb movements that disrupt sleep and lead to daytime fatigue. It is often associated with other conditions like RLS and ADHD, particularly in children and adolescents. The disorder causes significant sleep fragmentation and arousal, which can be identified through polysomnography. Accurate diagnosis is essential for effective management, as PLMD can be easily misdiagnosed without proper sleep studies.
