[A case of idiopathic torsion dystonia showing blepharospasm at the onset].
We report a 12-year-old boy with idiopathic torsion dystonia. Blepharospasm appeared at the age of 10, followed by truncal hypertonia and progressive scoliosis after 1 year. He had bizarre involuntary movement of his limbs upon waking, which was initially misinterpreted as a psychogenic reaction. Routine neurological examinations revealed no abnormality. Treatment with diazepam, bacrophen, 1-dopa, and clonazepam, led to only short time improvement of symptoms. At the age of 14, his symptoms gradually improved in natural course. At present he is 15 years old, and capable of normal daily activities. His clinical course was not typical of idiopathic torsion dystonia and very rare in children.
