Movement disorders encompass a spectrum of abnormal involuntary movements that can arise from lesions throughout the central nervous system or be associated with medical conditions. They include myoclonus, ballismus, chorea, athetosis, and dystonia. While sometimes difficult to distinguish, they often overlap and can have similar underlying causes such as genetic disorders, drugs, vascular events, and metabolic derangements. Treatment involves managing underlying conditions when possible and may include medications like valproic acid or botulinum toxin injections.
