## Abstract The effects of both opiate agonists and the opiate antagonist naloxone were examined in a rodent model of tardive dyskinesia (TD). Chronic (ห20 weeks) administration of fluphenazine resulted in the emergence of vacuous chewing mouth movements (VCMs), a response which may be a useful mod

โฆ Synopsis
Tardive dyskinesia (TD), a hyperkinetic disorder associated with long-term neuroleptic treatment, may be a manifestation of imbalance of opposing DA and ACh dependent systems in the CNS (i.e., hyperdopamine activity or hypoeholinergic function). Dopamine blocking agents give some transient relief of symptoms. Physostigmine, an anticholinesterase which enhances CNS acetylcholine action, has been given to 7 subjects with TD and measurements of their pathological movements made before, 45 min and 24 h later. All 7 subjects showed significant suppression of movement at 24 h. Many showed measurable decrement at 45 rain. Side effects were minimal and transient. Physostigmine suppresses movements of TD.
