when there are disturbances to this symptom.
- More common with typical antipsychotics
- Primarily consist of four primary dimensions:
1. Parkinsonian symptoms

3. Acute dystonia
4. Tardive dyskinesia
,EPSE: parkinsonism
Rigidity, mask like face, shuffling gait, tremor at rest, difficulty speaking or swallowing.
Resolved with anticholinergic or
antiparkinsonian drugs or possibly a change in medication.
EPSE: akathisia

May be reversible if recognised early & medication is stopped
, Neuroleptic Malignant Syndrome
