Original abstract
We report a case of juvenile Parkinson's disease which initially presented as bulbar incoordination at the age 12. The condition was characterized by dystonia of the upper extremities. The patient was a 14-year-old female. The patient's main symptoms were bulbar dysfunction. Resting and action tremor, akinesia, stooped posture, distortion of the trunk, dystonia of the upper extremities, oculogyric crisis, and impairment of the postural reflex were seen. The bulbar symptoms were considered to be attributable to circumoral uncoordination. Although L-dopa decarboxylase inhibitors were markedly effective in alleviating these symptoms, an adverse reaction due to the agent was observed as the form of oral dyskinesia. Since the changes in blood concentration of L-dopa after administration of the agent was clearly reflected in the surface electromyogram, we concluded that this diagnostic procedure is useful in evaluating the therapeutic efficacy of L-dopa.
