This document discusses Meige syndrome, which involves involuntary contractions of the muscles around the eyes (blepharospasm) and mouth (oromandibular dystonia). It can be primary or secondary to conditions like neuroleptic medication use or brain injuries. Pathophysiology may involve dopaminergic/cholinergic hyperactivity or decreased inhibitory neurons in the cortex. Diagnosis involves tests like EMGs and imaging to rule out other causes. Treatment options include anticholinergics, dopamine antagonists, Botox injections, and deep brain stimulation. Differential diagnoses include other movement disorders or neurological/psychiatric conditions.
