The most common disorder in a patient presenting to a movement disorder clinic will be parkinsonism. The challenge is to provide the patient with the most accurate diagnosis and prognosis possible. The assumption at the time of initial presentation of the clinical diagnosis of Parkinson's disease is often wrong (20-25%). Waiting to see the pattern of(More)
Presented here are four cases of catatonic reactions which were felt to be neuroleptic induced. Intravenous lorazepam was rapidly effective in reversing the catatonia and attendant symptoms. Lorazepam's previous uses and pharmacological profile are discussed. Reviewed briefly are catatonia and its neuroleptic-induced forms. Possible mechanisms responsible(More)
Deep brain stimulation (DBS) has virtually replaced thalamotomy for the treatment of essential tremor. It is thought that the site for DBS is the same as the optimal lesion site; however, this match has not been investigated previously. We sought to determine whether the location of thalamic DBS matched the site at which thalamotomy would be performed.(More)
Glossopharyngeal neuralgia is an uncommon craniofacial pain syndrome. An association with syncope is even less common. We report a case illustrating that the glossopharyngeal neuralgia-syncope syndrome can occur without pain in the sensory distribution of the glossopharyngeal nerve and that it can have similar consequences. We suggest that permanent cardiac(More)
BACKGROUND Dystonia must be accurately diagnosed so that treatment can be administered promptly. However, dystonia is a complex disorder, with variable presentation, which can delay diagnosis. METHODS Data were gathered by questionnaire from 866 patients with dystonia or hemifacial spasm (HFS) treated in 14 movement disorders centres in Canada injecting(More)
We describe eight cases of primary cerebral lymphoma seen in Manitoba from 1980 to 1985. The clinical presentation is similar to other primary brain tumors. The diagnosis should be considered when single or multiple, often deep lesions, show dense enhancement on computerized tomographic (CT) scan, but are avascular at angiography. These tumors are(More)
