* Acute dystonic reactions: painful, muscular spasms of neck, jaw, back, extremities, eyes, throat, and tongue; highest risk in young men. * Oculogyric crisis is a kind of acute dystonic reaction that involves the prolonged involuntary upward deviation of the eyes. * Akathisia: A feeling of internal motor restlessness that can present as tension, nervousness, or anxiety. Clinical manifestations include pacing and an inability to sit still. * Pseudoparkinsonism: drug-induced parkinsonism (rigidity, bradykinesia, tremor, masked facies, shuffling gait, stooped posture, sialorrhoea, and seborrhoea; greater risk in the elderly). Although Parkinson's disease is primarily a disease of the nigrostriatal pathway and not the<unk>  system, loss of dopaminergic neurons in the substantia nigra leads to dysregulation of the<unk>  system. Since this system regulates posture and skeletal muscle tone, a result is the characteristic bradykinesia of Parkinson's. * Tardive dyskinesia: involuntary muscle movements in the lower face and distal extremities; this can be a chronic condition associated with long-term use of antipsychotics.
