title: [Widespread tau abnormality in a case of cortico-basal degeneration].
abstract: A case with cortico-basal degeneration was reported with special reference to the immunohistochemical study. A 59-year-old housewife noted tremor and clumsiness of her left hand. On the initial examination she showed the hyperreflexia of the upper extremities and jaw jerk, parkinsonian symptoms such as Myerson sign, parkinsonian gait and rigidity in the left arm. She showed pronounced forced grasping in the left hand. At the age of 60 she showed a WAIS scale with verbal IQ of 99 and performance below the scale. She could not copy hand postures. Tremor was aggravated by action or anxiety, more prominent on the left hand. There was some incoordination on the finger-nose testing of left arm and on the knee-heel testing of both legs. She also showed homolateral dyskinesia. She had a left Babinski sign and sensory testing was normal. A CT scan showed slightly enlarged ventricles (Fig. 1). At the age of 61 she could not understand simple requests and speak few words spontaneously, showing severe dysarthria. There were palilalia and motor impersistence. CT scan showed more widening of the lateral ventricles. At the age of 62, she had lingual dyskinesia and tapping on her upper lip provoked myoclonic jerk on her arms. She died of pneumonia at the age of 65 years, 6 years from the onset. The brain weighed 1190 g. There were bilateral old subdural hematomas on the right parietal and occipital lobe and the left parietal lobe. There was atrophy of frontal and superior parietal region.(ABSTRACT TRUNCATED AT 250 WORDS)
