Movement disorders following midbrain haemorrhage are infrequently encountered in rehabilitation, and are uncommonly corrected by pharmacologic means. This report describes a 20 year-old male with a prior history of cocaine abuse who presented with a 4 day history of dysarthria and blurred vision following methamphetamine abuse. Physical examination demonstrated hypertension, left facial hemispasm, bilateral upward gaze paresis and ataxic gait. Magnetic resonance imaging/magnetic resonance angiography (MRI/MRA) showed multifocal parenchymal haematomas in the mesencephalic tegmentum, subcortical left front region and right anterior thalamus consistent with cavernous angiomas. The patient was transferred to rehabilitation on hospital day 5. The following day, he developed choreoathetoid movements, dystonia, and aphasia, secondary to an extension of the midbrain haemorrhage. Cogentin was initiated with slight improvement in choreoathetoid movements. The patient began intensive multidisciplinary rehabilitation therapy but after 18 days of therapy, the patient remained totally dependent in activities of daily living (ADLs), transfers, mobility and was unable to communicate in any manner. A trial of Sinemet was initiated, with resultant steady improvement in functional ability over the next month. By discharge, the patient was independent in ADLs and ambulation. By 9 months post discharge follow-up, the patient was fully independent with normal cognition, and had self tapered all medications without ill effect. Dopamine agonist trials of appropriate duration appear indicated in cases of movement disorder (paucity or excess) following midbrain lesions.

A 5-year-old boy with hydrocephalus and a lumbar myelomeningocele underwent extension of peritoneal tube of ventriculoperitoneal (VP) shunt system. Prior to the operation he had been able to walk independently with the use of braces, to speak complex sentences and to sing songs. After the surgery, he lost consciousness and became critically ill with irregular respiration. He was artificially ventilated for 10 days, and then recovered, with sequelae of right facial paresis and slight dysarthria. T1 weighted magnetic resonance image showed high intensities of the medial part of the inferior lobe of the cerebellum and medulla oblongata, which were interpreted as representing edema. This case illustrates that Chiari II malformation can become symptomatic after a VP shunt trouble.

A 30-year-old female became comatose due to embolic occlusion of the basilar artery, caused by surgical injury to the origin of the vertebral artery during removal of a neurinoma in the upper thoracic paravertebral region. The basilar artery occlusion was treated by local fibrinolysis through a microcatheter. Two weeks later she recovered her consciousness but suffered mutism. Her speech disturbance was characterized by severe ataxic dysarthria known as "cerebellar mutism" but without cranial nerve paresis. The mutism gradually improved during the following 3 months. This is case of cerebellar mutism was apparently due to ischemic stroke. Disturbance by hypoperfusion of the cerebellum and brain stem may have been involved in the pathogenesis of cerebellar mutism.

1. Amyotrophic lateral sclerosis (ALS) is a degenerative disorder characterized by selective damage to the neural system that mediates voluntary movement. Although the pathophysiologic process of ALS remains unknown, about 5 to 10% of cases are familial. According to genetic linkage studies, the familial ALS (FALS) gene has been mapped on chromosome 21 in some families and recent work identified some different missense mutations in the Cu/Zn superoxide dismutase gene in FALS families. 2. We recently identified five mutations in six FALS families. The mutations identified in our FALS families are H46R, L84V, I104F, S134N, and V148I. The H46R mutation that locates in the active site of Cu/Zn SOD gene is associated with two Japanese families with very slow progression of ALS. On the other hand, the L84V mutation associated with a rapidly progressive loss of motor function with predominant lower motor neuron manifestations. 3. In the family with the V148I, the phenotype of the patient varied very much among the affected members. One case had weakness of the lower extremities at first and died without bulbar paresis. The second case first noticed wasting of the upper limbs with bulbar symptoms, but the third had weakness of upper extremities without developing dysarthria nor dysphagia until death. These mutations account for 50% of all FALS families screened, although Cu/Zn SOD gene mutations are responsible for less than about 13-21% in the Western population. 4. Our results indicate that the progression of disease with mutations of Cu/Zn SOD is well correlated with each mutation. The exact mechanism by which the abnormal Cu/Zn SOD molecules selectively affect the function of motor neurons is still unknown.

We present an occult metastatic signet-ring cell gallbladder carcinoma in a 78-year-old woman, who complained of recurrent headaches, dysarthria, and paresis of the tongue. Cranial imaging showed contrast enhancement of the basal leptomeninges, and the cerebrospinal fluid displayed clusters of adenocarcinoma cells proposed as leptomeningeal carcinomatosis of the breast, lung or gut. However, postmortem examination revealed the gallbladder as the site of the primary carcinoma with focal signet-ring cell differentiation. In patients with progressive neurologic deterioration due to leptomeningeal carcinomatosis, adenocarcinomas from the gastrointestinal and hepatic systems should be considered. It is likely that signet-ring cell carcinomas display an increased affinity to leptomeningeal spread.

Among the numerous clinical syndromes observed after severe traumatic head injury, post-traumatic mutism is a disorder rarely reported in adults and not studied in any detail in children. We report seven children between the ages of 3 1/2 and 14 years who sustained severe head injury and developed post-traumatic mutism. We aim to give a precise clinical characterization of this disorder, discuss differential diagnosis and correlations with brain imaging and suggest its probable neurological substrate. After a coma lasting from 5 to 25 days, the seven patients who suffered from post-traumatic mutism went through a period of total absence of verbal production lasting from 5 to 94 days, associated with the recovery of non-verbal communication skills and emotional vocalization. During the first days after the recovery of speech, all patients were able to produce correct small sentences with a hypophonic and monotonous voice, moderate dysarthria, word finding difficulties but no signs of aphasia, and preserved oral comprehension. The neurological signs in the acute phase (III nerve paresis in three of seven patients, signs of autonomic dysfunctions in five of seven patients), the results of the brain imaging and the experimental animal data all suggest the involvement of mesencephalic structures as playing a key role in the aetiology of post-traumatic mutism.

We report a case of a unique eye sign following right hemispheric infarction. This patient was a 78 year old right-handed woman. There was a history of a left hemispheric stroke 1 year previously. On admission, she showed left hemianopia, dysarthria, mild left central facial paresis, bilateral sensory deficit and quadriparesis which were marked on the left side. Babinski sign was elicited on the left. She did not have anosognosia or visual neglect. She had mild orofacial apraxia, but ideomotor and ideational apraxia was absent. There was no motor impersistence. Magnetic resonance imaging of the brain revealed a recent infarction in the territory of the right middle cerebral artery and an old infarction in the left tempro-parietal lobe. The patient could not open her eyelids to verbal command or voluntarily until about two weeks later, when she became able to open her eyes but showed difficulty keeping her left eye closed. She was aware of this problem and could repeat the command and comprehend what was requested to her. On verbal command to close the eyes, her right eye would be closed continuously and excessively and the left eye would only blink. When requested to blink, however, she could blink correctly without excessive eye closure. Spontaneous, reflex and voluntary blinking were normal. Her eyes were closed normally during sleep. Blepharospasm was not seen. The patient showed a striking dissociation between a failure to close her eyes continuously and a preserved ability to blink voluntarily. We suggest that her ability to contract palpebral portion of her left orbicularis oculi muscle is preserved. Regarding the mechanism of the voluntary eye closure system, separate control mechanisms should exist on closing eyes continuously and blinking.

We report here a girl aged 5 years 3 months with cryptogenic localization-related epilepsy who showed a prolonged episode characterized by dysarthria, dysphagia, drooling and paresis of the right arm associated with almost continuous diffuse sharp-slow wave complexes during sleep. These symptoms were not directly related to seizures or to each sharp-slow wave complex revealed by examination during the video electroencephalographic (EEG) recording. The interictal single photon emission compute tomography showed a localized high perfusion area in the left posterior frontal region. The introduction of clonazepam completely controlled the clinical symptoms as well as the EEG abnormality within 2 weeks. After 4 months of remission, a similar episode recurred which was associated with aggravation of EEG. The clinical and EEG characteristics of this patient were identical to those of acquired epileptiform opercular syndrome (AEOS), a newly proposed epileptic syndrome, in which a transient operculum syndrome develops in association with continuous spike-and-wave activity during slow sleep (CSWS). Computer-assisted EEG analysis demonstrated that the epileptic EEG focus was located in the left sylvian fissure, and produced secondary bilateral synchronous sharp-slow complexes. The present study further supports the hypothesis that the electrical interference by CSWS creates bilateral opercular dysfunction through the mechanism of secondary bilateral synchrony, thus producing AEOS.

In the last 10 years, wound botulism has increasingly been reported and nearly all of these new cases have occurred in injecting-drug abusers. After absorption into the bloodstream, botulinum toxin binds irreversibly to the presynaptic nerve endings, where it inhibits the release of acetylcholine. Diplopia, blurred vision, dysarthria, dysphagia, respiratory failure and paresis of the limbs are common symptoms of this intoxication. Surprisingly and despite the well-known blocking action of the botulinum toxin on the autonomic nerve system, little attention has been paid to changes in the lower urinary tract following acute botulinum toxin poisoning. Here we report a case of bladder paralysis following wound botulism. Early diagnosis and adequate management of bladder paralysis following botulism is mandatory to avoid urologic complications. Accordingly, the prognosis is usually favorable and the bladder recovery complete.

This study concerns an autopsy case of motor neuron disease with dementia (MND-D) that exhibited unusual clinical and neuropathological findings. The patient was a Japanese man without any relevant family history who was 60 years old at the time of death. His clinical manifestation included character change at the age of 54, followed by frozen gait, dysarthria and bradykinesia and he was diagnosed with Parkinson's disease. He gradually developed spastic paresis and died of respiratory failure 6 years after onset of the illness. Neuropathological examinations showed prominent degeneration in the striatonigral and pallidoluysian systems in addition to the neuronal loss and microvacuolation in the second to third layers of the frontal and temporal cortex, the involvement of the upper and lower motor neuron systems and the presence of ubiquitinated neuronal inclusions. To our knowledge, five cases of motor neuron disease (MND) combined with pallido-nigro-luysian atrophy (PNLA) have been reported previously, but the present case is the first report of MND-D combined with the degeneration of the striatonigral and pallidoluysian systems. Such an association may represent more than a coincidental occurrence, and it suggests that MND-D is not simply a disease of the motor neuron system but a multisystem degeneration.
