Higher auditory function in a patient was investigated following a right hemisphere infarction between the middle and posterior cerebral artery territories involving the insula. The patient complained of lack of musical appreciation and a battery of tests confirmed a dissociated receptive musical deficit in the presence of normal appreciation of(More)
When the WHO's Topic Advisory Group for Neurology (TAG) started work on revision of the ICD-10 diagnostic codes in June 2009, the issues were daunting. The existing classification was produced a generation ago and the need to move to the digital age was becoming imperative. Appreciating modern advances in genetics and immunology, and the consequent changes(More)
Human listeners can localize sounds by the difference in both arrival time (phase) and loudness between the two ears. Movement of the sound source modulates these cues, and responses to moving sounds have been detected in animals in primary auditory cortex and in humans in other cortical areas. Here we show that detection of changes in the interaural phase(More)
We treated 15 children with Sydenham's chorea with sodium valproate at a dose of 15 to 20 mg/kg/d. In 13 of them the chorieform movements disappeared within 1 week of therapy. The remaining 2 had incomplete response. Two patients relapsed; 1 of them responded to the reintroduction of valproate. The mean duration of treatment was 6.7 weeks. We observed no(More)
On December 31, 1988 there were 201 registered multiple sclerosis patients in Kuwait, an overall prevalence rate (PR) of 10.2 per 100,000; among them were 186 Arabs, of whom 72 were Palestinians and 51 Kuwaitis. Comparison of these two subgroups, who had a similar age distribution revealed that the disease was 2 1/2 times more frequent among Palestinians(More)
The syndrome of spontaneous intracranial hypotension (SIH) is an uncommon cause of postural headache. We describe three patients with classical low pressure headache associated with low CSF pressure, one of whom presented with sudden deafness and another with a unilateral VIth nerve palsy. Initial magnetic resonance imaging (MRI) scans revealed bilateral(More)
Neurocysticercosis is a major cause of epilepsy and other neurological morbidity in endemic areas of the world but is exceptionally rare in the West. We have recently had experience of eight patients with this condition, seven presenting with epilepsy and single or multiple small, enhancing parenchymal lesions and one with hydrocephalus caused by a midbrain(More)
Twenty-one patients with myasthenia gravis underwent a course of plasma exchange combined with immunosuppressive therapy. In fifteen there was dramatic clinical improvement which has been maintained for periods up to 19 months. Nine of these patients now take no anticholinesterase drugs. Six patients had a recurrence 3--9 months after the first course but(More)
Brucellosis rarely can present with involvement restricted to the nervous system. We describe a total of 19 cases of neurobrucellosis in whom the clinical presentation lay in three distinct categories. The first was an acute presentation with meningoencephalitis. The disease also presented in a chronic form where the brunt of the illness can either be in(More)
