The first autopsy of a case of multiple sclerosis from the District of Hokuriku was reported. The patient, a 50-year-old house-wife, born in Toyama Prefecture, had noticed a paresthesia of her face, fatigue, numbness and weakness in the right limbs, dimness of vision and gait disturbance at ave 44. Furthermore, in the course of the disease, she had suffered from visual disorder, tetraplegia, hyperreflexia, pyramidal signs and cerebellar syndroms such as dysarthria, nystagmus, intention tremor and ataxia. She also showed symptoms of euphoria and dementia. After a course of six years she died of bronchopneumonia. Remissions and exacerbations were noted four times during her clinical history. Histopathologically, there were many recent and old demyelinating lesions of varying sizes and shapes in all parts of the central nervous system, namely the cerebrum, brainstem, spinal cord and optic nerve. In contrast to the clinical symptoms, the cerebellum itself revealed less plaques than the other areas of the brain. According to the observed distributions of the lesions, our case can be classified as belonging to the optico-cerebro-spinal type in the Ikuta and Zimmerman classification. The demyelinated lesions were characterized by a perivenular distribution of the plaques, lack of tissue necrosis, paucity of inflammatory reaction and marked fibrous gliosis of varying degrees.

An account is given of a form of hereditary, cerebellar ataxia and photomyoclonus. Eight cases from 5 generations were affected. The disease seemed to be transmitted as an autosomal dominant trait. The age at onset usually varied between 35 to 40 years. The symptoms and signs consisted of a cerebellar ataxia, dysarthria and intention tremor. There was no nystagmus. All patients exhibited photomyoclonus and were extremely sensitive to photic stimuli. Other signs were dementia, kyphosis, pes cavus and lipoma localized in the nape of the neck, shoulders and back. Two patients had a partial syndrome with photonyoclonus and skeletal deformities. None of the patients suffered from epilepsy, In one case, histopathological examination revealed atrophy within the cerebellar cortex, dentate nucleus and the posterior columns of the spinal cord. It is concluded that this syndrome belongs to a groups of hereditary ataxias and myoclonus, and differs from myoclonic cerebellar dyssynergia (Ramsay Hunt) and alos from a variety of familial myoclonus and ataxia (Gilbert et al. 1963);

Infantile neuroaxonal dystrophy is a degenerative disease, mostly of nerve endings in the central and peripheral nervous system, with typical pathological findings. We describe a 3-year-old boy who had suffered from nystagmus, progressive muscle weakness and dementia since the age of 10 months. Biochemical work-up, MRI of the brain, and electrophysiological studies were within normal limits. Only skin biopsy, and sural nerve biopsy at a later stage, were diagnostic. We stress the importance of performing tissue biopsy even when intensive investigation is negative.

Wernicke encephalopathy and Korsakoff psychosis are two facets of the same disease with well-determined cerebral lesions caused by thiamine deficiency. The disease occurs mainly in alcoholics, but other conditions (malabsorption or severe malnutrition) also predispose to the risk of Wernicke-Korsakoff syndrome. The incidence in Denmark is unknown. In the period 1.1.1979-31.12.1988, 24 patients (18 men and six women) were discharged from Rigshospitalet with the diagnosis Wernicke encephalopathy or Korsakoff psychosis. This represents about 0.05% of all admissions in the period. Eighteen out of the 24 cases (75%) were admitted in the past three years (1986-88). The mean age was 55 years. Twenty patients admitted alcohol abuse. The presenting symptoms and the patients' complaints showed great variety and were often related to other alcoholic complications, which could mask the disease. The classic symptom combination: eye movement abnormalities- ataxia and disorders of consciousness were found in seven patients (29%). Sixteen patients had disorders of consciousness or orientation. All the patients were treated with thiamine. The eye-movement disorder has recovered in eight out of ten known cases (80%), nystagmus--in six out of seven cases (86%) while ataxia, disorders of orientation and confabulation recovered in about 50% of cases. The average duration of hospitalisation was 50 days. Altogether nine patients died during the observation period. The condition is most probably underdiagnosed and the traditional diagnostic criteria are considered too rigid. The diagnosis should be considered in alcoholics who present even only one of the classical symptoms and in patients with alcohol dementia. Thiamine should be given on wide indications.

A case of metastatic small cell carcinoma to the pineal body is reported and the clinical and radiological features of this rare tumor are discussed. A 66-year-old man presented with progressive dementia, gait disturbance, vertical gaze palsy, and convergence retraction nystagmus. Computed tomographic scan revealed a 2 X 3-cm high-density mass in the pineal region, which showed strong contrast enhancement. The tumor was resected through a right occipital transtentorial approach. The pathological diagnosis of the surgical specimens was small cell carcinoma. A systemic workup for the primary lesion subsequently revealed small cell carcinoma of the lung. Although occurring rarely, metastatic tumor should be considered in the differential diagnosis of pineal tumor in elderly patients.

Seventy five patients affected by senile dementia of the Alzheimer type (mean age 82) have been submitted to a standardized neurological examination of 88 items. Gait abnormalities were present in 57% of the cases. Extrapyramidal symptoms (akinesia or rigidity or tremor) were noticed in 64% of the cases but they were rarely associated with a typical parkinsonian syndrome. Myoclonus was observed in only 4 patients. The gait abnormalities were significantly associated with the presence of rigidity and grasp reflex but not with other primitive reflexes. The only symptoms to be correlated with dementia severity as assessed by the Mini Mental State were rigidity and optokinetic nystagmus abolition. Tremor and amyotrophy of the hands appeared to be negatively correlated to dementia severity.

A 69-year-old male, with a history of a previous subdural hematoma, multistroke dementia and ventricular shunting for hydrocephalus, exhibited while comatose isolated periodic alternating rotatory nystagmus with cyclic pupillary changes and periodic alternating gaze. His simultaneous EEG showed PLEDs and subsequently burst-suppression pattern. The latter abnormality was associated, in addition, to transient eyelid opening, synchronized with the EEG bursts. Complex neuro-ophthalmologic clinical signs, sometimes subtle, may be the sole manifestation of EEG periodic complexes that have potential prognostic and therapeutic implications.

Quantitated automated electro-oculographic data from 45 parkinsonian patients were compared with those from 30 normal control subjects. Patients were selected with idiopathic Parkinson's disease without other associated neurological disease or dementia; 20 had never received antiparkinsonian drugs and in 25 such treatment had been stopped for at least 2 days. Saccade latency, amplitude and peak velocity, smooth pursuit peak velocity, optokinetic nystagmus (OKN) maximal and mean velocities and vestibulo-ocular reflex (VOR) suppression by vision or imagination were significantly altered in patients, whereas VOR gain in darkness was normal. Alterations of saccade latency and smooth pursuit peak velocity were more severe in the more advanced stages of the disease and saccade latency directed towards the symptomatic side was slightly delayed in hemiparkinsonian patients. Saccade amplitude improved 90 min after a single oral dose of L-DOPA. These results suggest a possible dopaminergic control of some ocular movements.

We found abnormal supranuclear ocular or lid motility in all of 37 patients with Lytico-Bodig (amyotrophic lateral sclerosis/parkinsonism-dementia complex). Twenty-one patients had pursuit paresis, 18 abnormal vestibulo-ocular reflex (VOR) cancellation, 15 abnormal convergence, 13 abnormal optokinetic nystagmus (OKN), 12 conjugate gaze limitation, nine nystagmus, nine saccadic paresis, and six abnormal fixation. Lid abnormalities included glabellar hyperreflexia in 21, involuntary levator inhibition in three, and blepharospasm in two. Earlier reports have indicated infrequent ocular disturbances in Lytico-Bodig, but we now find supranuclear eye and lid deficits are universal and sometimes very prominent.

Computed tomographic (CT) findings of cerebral and cerebellar calcification are described in three American adults with raised serum lead levels and known exposure to lead for 30 or more years. Calcification patterns were punctiform, curvilinear, speck-like, and diffuse and were found in the subcortical area, basal ganglia, vermis, and cerebellum. Admission serum lead levels ranged from 54 to 72 micrograms/dl (normal, 0-30 micrograms/dl). Nonspecific neurologic manifestations consisted of dementia, diminished visual acuity, peripheral neuropathy, syncope, dizziness, nystagmus, easy fatigue, and back pain. Two patients developed chronic renal disease and hypertension; in both cases, serum parathormone was elevated. Blood, calcium, and phosphorus were normal in all three. No other structural abnormalities were observed with CT. Although the pathophysiologic mechanism of these findings remains poorly understood, it is suggested that chronic lead exposure should be included in the differential diagnosis of unexplained intracranial calcifications in adults.
