title: [Oculogyric crisis as an initial symptom of juvenile parkinsonism-like disease].
abstract: A 12-year-old boy developed occasional attacks of oculogyric crisis after physical exercises or when tired. Following the initial symptom, progressive Parkinsonian features such as bradykinesia, muscular rigidity, hand tremors in posture, mild dysarthria and disorder of postural reflexes developed. There was no marked diurnal fluctuation o symptoms. Serum ceruloplasmin, copper levels, cranial X-ray CT scan and MRI were normal. Measurement of the plasma levels of L-dopa after single oral administration (300 mg) were normal. The treatment with L-dopa improved the Parkinsonian features excluding the attacks of oculogyric crisis in a few weeks. This case is not identical with juvenile Parkinsonism proposed by Yokochi et al for lack of both crural or truncal dystonia and remarkable response to L-dopa. Oculogyric crisis is known in several patients with severe generalized dystonia, and seldom in patients with Parkinson disease or juvenile Parkinsonism. Oculogyric crisis may be one of focal dystonias confined to extraocular muscles.
