Gary is exhibiting symptoms of tardive dyskinesia, which is a side effect commonly associated with long-term use of antipsychotic medications. Savant syndrome is a rare condition in which individuals have extraordinary abilities in certain areas despite having significant cognitive or developmental disabilities. A clozapine overdose would result in symptoms of toxicity, such as confusion, agitation, seizures, and coma. Neuroleptic malignant syndrome is a potentially life-threatening reaction to antipsychotic medication characterized by high fever, muscle rigidity, and autonomic dysfunction.
