Summary
Tardive dystonia (Tdt) is a rare condition usually linked to neuroleptics. This case report details Tdt developing after lithium treatment, responding well to clozapine.
Area of Science:
- Neurology
- Pharmacology
Background:
- Tardive dystonia (Tdt) is an uncommon chronic movement disorder.
- It typically arises from exposure to neuroleptic medications.
Observation:
- A 38-year-old male with bipolar disorder developed Tdt.
- This occurred during maintenance therapy with lithium.
- No recent neuroleptic exposure was noted.
Findings:
- This is the first reported case of Tdt following lithium therapy.
- The patient's Tdt responded favorably to clozapine, an atypical antipsychotic.
- This suggests Tdt can be induced by non-neuroleptic drugs.
Implications:
- Tardive dystonia may develop from various medications beyond neuroleptics.
- Clozapine presents a potential treatment option for drug-induced tardive dystonia.
- Further research into lithium-induced Tdt and its management is warranted.
