Summary
Anticholinergic medications, including trihexyphenidyl and ethopropazine, effectively treated torsion dystonia in children and adults. Children experienced higher benefit rates, while adults faced more adverse effects limiting dosage.
Area of Science:
- Neurology
- Pharmacology
Background:
- Torsion dystonia is a movement disorder characterized by involuntary muscle contractions.
- Various etiologies and movement patterns exist within torsion dystonia.
Purpose of the Study:
- To evaluate the efficacy and tolerability of anticholinergic medications in treating torsion dystonia.
- To determine optimal dosages and identify factors influencing treatment outcomes.
Main Methods:
- An open-label study involving 23 children and 52 adults with torsion dystonia.
- Gradual dose escalation of anticholinergic medications (trihexyphenidyl, ethopropazine) until benefit or adverse effects occurred.
Main Results:
- Significant benefit was observed in 61% of children and 38% of adults.
- Average daily dosages: 41 mg trihexyphenidyl (children), 24 mg trihexyphenidyl (adults), 350 mg ethopropazine (adults).
- Adverse effects limited high dosages primarily in adults.
Conclusions:
- Anticholinergic therapy offers significant benefits for torsion dystonia, particularly in pediatric patients.
- Dosage and tolerability vary between children and adults, with adults experiencing more dose-limiting side effects.
