Dystonic reactions are the first extrapyramidal symptoms to occur when a patient is taking antipsychotic agents. Dystonias are spasmodic movements of muscle groups such as tongue protrusion, rolling back of the eyes (oculogyric crisis), jaw spasms (trismus), or neck torsion (torticollis). Pseudoparkinsonism is characterized by tremor and rigidity. Akathisia is characterized by subjective feelings of anxiety and restlessness, accompanied by pacing and the inability to remain in one place for extended periods. Tardive dyskinesia is characterized by persistent involuntary hyperkinetic movements.
