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)

Thirty-six parkinsonian patients were selected by age of onset of over 70 and a minimum of five years duration of illness. The mean age of onset was 73.5 years and 30 patients were still alive after a mean of 7.2 years. We found that late onset Parkinson's disease has a relatively benign course with more "axial symptoms" especially dysarthria, freezing and postural instability. Dyskinesias and fluctuations are rare and dementia occurs in few patients in spite of their old age.

The neurologic states and activities of daily life of patients with Parkinson's disease were evaluated using a rating scale with subitems, and subsequently the neurologic disturbance scores and the daily activity impairment scores were obtained. Subjects consisted of 19 normal controls, and 55 ambulatory patients without marked dyskinesia who were on various anti-parkinsonian drugs. Blink reflex was elicited by paired electrical stimulation over the supraorbital nerve. The interval time between the conditioning stimulation and the test stimulation was set at 200 ms, and 5 serial ipsilateral maximal R2 amplitudes on the stimulated side were measured. The mean of the paired maximal R2 amplitude ratio (test/conditioning), expressed as a percentage, was defined as the habituation index. The habituation indices in normal controls and those with Parkinson's disease were 17.1 +/- 7.6 and 51.9 +/- 29.3, respectively (P less than 0.01). The degree of akinesia, rigidity, balance/gait and dysarthria was positively correlated with the habituation index (P less than 0.01), while tremor was not. On the whole the habituation index was found to have a significant correlation not only with the neurologic disturbance score but also with the daily activity impairment score (P less than 0.01).

A 15-year-old boy was diagnosed as having Wilson disease. He perceived involuntary tongue movement and speech disorder since March 1990. The tongue movements presented in the resting state and during action. It contracted transversely and bilaterally with an irregular frequency about 1 Hz. As a result, the sides of the tongue moved to form a narrow central groove. This was quite different from the tongue protrusion of tardive dyskinesia. His speech had imprecise consonants, monopitch, low pitch, low volume, harsh voice, and hyponasality. These suggested that tongue dyskinesia could be an early sign of Wilson disease and was not the main cause of his dysarthria.

Metoclopramide is a widely used product, which can accidentally cause acute dyskinesia, of which several forms may be observed, including dysarthria, tetany, spasmophilia, false cerebral vascular insult, trismus, hysteriform spell.... In all those cases, one should think of giving an antiemetic and of properly orienting history-taking, thus avoiding a longer stay in hospital that would not be justified. This is demonstrated by two patients recently admitted into the department of maxillofacial surgery and stomatology with maxillofacial signs related with the adverse effects of this kind of drug.

Using exploratory factor analysis, we prospectively investigated neuropsychiatric symptoms and structural brain lesions of 47 patients with proven Wilson's disease and identified three subgroups. The first subgroup clinically exhibited bradykinesia, rigidity, cognitive impairment, and an organic mood syndrome and by MRI showed a dilatation of the third ventricle. The second subgroup was characterized by ataxia, tremor, reduced functional capacity, and focal thalamic lesions. The third subgroup showed dyskinesia, dysarthria, an organic personality syndrome, and focal lesions in the putamen and in the pallidum.

We report a 91-year-old man who had a stroke and died of renal failure. He had been treated for hypertension since 20 years before the onset of the present illness. In addition, he was operated on a gastric cancer 17 years previously. Otherwise he was doing well until May 29, 1991 (when he was 87-year-old) when he had sudden onset of dysarthria and right facial weakness. He was admitted to our hospital. On admission, general physical examination was unremarkable, and neurologic examination revealed a mentally sound man with slight dysarthria, right facial weakness, orolingual dyskinesia, and dysequilibrium in which he showed difficulty in tandem gait; however, no cerebellar ataxia was noted. A cranial CT scan revealed leukoaraiosis with multiple low density areas in the cerebral white matter. His BUN was 37 mg/dl and Cr 2.2 mg/dl. His neurologic symptoms cleared within the next few weeks and he was discharged with ticlopidine 100 mg q.d.. He had been doing well after the discharge except for gradual worsening of his renal function; his BUN was 65 mg/dl and Cr 3.27 mg/dl in April of 1994. On March 10, 1995, he fell down and hit his back; he became unable to walk because of pain, and he was admitted again on March 16, 1995. On admission, his blood pressure was 170/80 mmHg. There was an 1 + pitting pretibial edema; otherwise general physical examination was unremarkable. Neurologic examination revealed an alert and oriented man, however, Hasegawa's dementia scale was 23/30. Higher cerebral functions as well as cranial nerves were intact. He showed some unsteadiness of gait, however, no motor weakness or ataxia was noted. Deep tendon reflexes were diminished, but Chaddock sign was positive bilaterally. Vibration was diminished in the feet, however, pain and touch sensations were intact. Laboratory examination revealed a compression fracture of the twelfth thoracic vertebra. Blood count and chemistries were as follows; Hb 7.6 g/dl, Hct 23.3%, TP 6.0 g/dl, Alb 3.6 g/dl, BUN 87 mg/dl, Cr 4.53 mg/dl, T-Chol 174 mg/dl, HDL-Chol 49 mg/dl, Glu 156 mg/dl, Na 142 mEq/L, K 5.4 mEq/L, Cl 115 mEq/L. A urine specimen contained 1 + protein and 1 + glucose, and the sediments contained hyaline casts. A cranial CT scan was essentially same as that taken four years ago. His hospital course was complicated with pneumonia, congestive heart failure, and progressive renal failure. He was treated with intravenous fluid, chemotherapy, and other supportive measures, however, he expired from respiratory failure on April 30, 1995. He was discussed in a neurologic CPC, and the chief discussant arrived at the conclusion that the patient had Binswanger's disease in the brain, benign nephrosclerosis from arteriolosclerosis due to hypertension, congestive heart failure, and pneumonia. Opinions were divided regarding the question as to whether or not this patient had Binswanger's disease. Although his cranial CT scan revealed leukoaraiosis, his dementia and gait disturbance was only mild until his fall on March, 1995. Clinical features did not conform to those of Binswanger's disease. Postmortem examination of the right hemisphere revealed wide spread atherosclerosis and arteriolosclerosis. The kidney showed benign nephrosclerosis due to arteriolosclerosis. Sclerotic changes were also seen in the coronary arteries and the left middle cerebral artery with 70% stenosis. Myelin stain showed diffuse myelin pallor of the cerebral white matters with scattered small infarcts. Arterioles in the white matter showed arteriolosclerosis. Small infarcts were also seen in the putamen and in the thalamus. This patient appeared to have had circulatory disturbance of the white matter which is the basic abnormality causing Binswanger's disease. However, white matter changes in this patient were not quite severe enough to make a pathologic diagnosis of Binswanger's disease.

We studied the clinical features and molecular genetics of a family, afflicted with a form of atypical parkinsonism, originating from the Madeira Islands of Portugal. We examined four affected individuals and reviewed clinical information on one other affected family member. Mean age at onset was 31 years. Parkinsonism (akinesia, rigidity, gait disturbance) was the most prominent feature in advanced disease. Levodopa responsiveness with peak-dose dyskinesia was present in one individual. Initial symptoms and other clinical features were variable and included other extrapyramidal signs (dystonia, action tremor of the limbs and bulbar muscles, synkinesis), ophthalmologic abnormalities (ptosis, slow saccades, progressive external ophthalmoplegia, hypometric saccades, saccadic pursuit movements), speech abnormalities (dysarthria, hypernasality), cortical impairment (dementia, frontal lobe dysfunction, palilalia, perseveration), minor cerebellar signs (dysmetria, gait ataxia), pyramidal abnormalities (spasticity, hyperreflexia), and peripheral nervous system abnormalities (propioceptive loss, areflexia, distal weakness, atrophy). The length of trinucleotide repeats in the MJD1 gene was in the normal range for all affected individuals.

The authors report the underestimated cognitive, mood, and behavioral complications in patients who have undergone bilateral contemporaneous pallidotomy, as seen in their early experience with functional neurosurgery for Parkinson's disease (PD) that is accompanied by severe motor fluctuations before pallidal stimulation. Four patients, not suffering from dementia, with advanced (Hoehn and Yahr Stages III-IV), medically untreatable PD featuring severe "on-off" fluctuations underwent bilateral contemporaneous posteroventral pallidotomy (PVP). All patients were evaluated according to the Core Assessment Program for Intracerebral Transplantations (CAPIT) protocol without positron emission tomography scans but with additional neuropsychological cognitive, mood, and behavior testing. For the first 3 to 6 months postoperatively, all patients showed a mean improvement of motor scores on the Unified Parkinson's Disease Rating Scale (UPDRS), in the best "on" (21%) and worst "off" (40%) UPDRS III motor subscale, a mean 30% improvement in the UPDRS II activities of daily living (ADL) subscore, and 60% on the UPDRS IV complications of treatment subscale. Dyskinesia disappeared almost completely, and the mean daily duration of the off time was reduced by an average of 60%. Despite these good results in the CAPIT scores, one patient experienced a partially regressive corticobulbar syndrome with dysphagia, dysarthria, and increased drooling. No emotional lability was found in this patient, but he did demonstrate severe bilateral postoperative pretarsal blepharospasm (apraxia of eyelid opening), which interfered with walking and which required treatment with high-dose subcutaneous injections of botulinum toxin. No patient showed visual field defects or hemiparesis, but postoperative depression, changes in personality, behavior, and executive functions were seen in two individuals. Postoperative abulia was reported by the family of one patient, who lost his preoperative aggressiveness and drive in terms of ADL, speech, business, family life, and hobbies, and became more sleepy and fatigued. One patient reported postoperative mental automatisms, such as compulsive mental counting, and circular thoughts and reasoning during off phases; postoperative depression was found in two patients. However, none of the patients demonstrated these symptoms during intraoperative microelectrode stimulation. These findings are compatible with previous reports on bilateral pallidal lesions. A progressive lowering of UPDRS subscores was seen after 12 months, consistent with the progression of the disease. Bilateral simultaneous pallidotomy may be followed by emotional, behavioral, and cognitive deficits such as depression, obsessive-compulsive disorders, and loss of psychic autoactivation-abulia, as well as disabling corticobulbar dysfunction and apraxia of eyelid opening, in addition to previously described motor and visual field deficits, which make this surgery undesirable even though significant improvement in motor deficits can be achieved.

Acanthocytosis occurs because of ultrastructural abnormalities of the erythrocyte membranous skeleton resulting in reduced membrane fluidity. At least three hereditary neurological conditions are associated with it, although as yet the pathogenesis of the neurological features is unknown. In abetalipoproteinaemia, an autosomal recessive condition, vitamin E deficiency results in a progressive spinocerebellar syndrome associated with peripheral neuropathy and retinitis pigmentosa. Neuroacanthocytosis is also probably an autosomal recessive condition and is characterised by chorea, orofaciolingual dyskinesia, dysarthria, areflexia, seizures and dementia. McLeod syndrome is an X-linked recessive disorder usually presenting in males as a benign myopathy with areflexia, in association with a particular abnormality of expression of Kell blood group antigens. However, occasionally the neurological features are more severe and indistinguishable from those of neuroacanthocytosis. Recent advances in molecular genetics may assist better understanding of the disease mechanisms and the search for more effective treatments.
