Causes
Genetic mutations in certain types of dystonia Brain injury or stroke affecting movement areas Medications (e.g., long-term use of antipsychotics) Unknown in many cases
Diagnosis
Neurological examination Medical history and family history review Imaging or genetic testing if required
Treatment
Medications to reduce muscle contractions (anticholinergics, muscle relaxants) Botulinum toxin injections for focal dystonia Physical therapy to maintain mobility Deep brain stimulation in severe cases
Complications
Functional impairment affecting daily life Pain or fatigue from constant muscle contractions Social or emotional challenges due to visible symptoms
Prevention
