Understanding Acquired Dystonia and Its Causes
Acquired dystonia manifests through sustained muscle contractions that lead to abnormal movements and postures, often triggered by identifiable external events. Common causes include the use of dopamine-blocking medications, which may result in drug-induced or tardive dystonia. Other contributing factors can be brain injuries from trauma or stroke, as well as infections like viral encephalitis and toxic exposures to substances such as manganese or methanol. Additionally, conditions such as cerebral palsy resulting from perinatal brain injuries can also lead to acquired dystonic syndromes, highlighting the diversity of potential triggers.
