AIMS To assess the visual function in epileptic patients who have received vigabatrin; to compare this with the visual function in similar epileptic patients who have never received vigabatrin; to investigate whether the severity of visual field defect (VFD) is related to the dose of vigabatrin; to consider other factors that may correlate with the severity… (More)
Parkinson's disease patients have been shown to have abnormal visually evoked cortical potentials (VEPs) to pattern stimulation. Whereas dopamine is not an important neurotransmitter in the central visual pathways, the retina is rich in dopamine and, together with previous animal and human studies, this suggests that the abnormal VEPs in Parkinson's disease… (More)
A patient with a severe organic schizophreniform illness is described in whom the bizarre psychotic features were related to a non-dominant parietal lobe lesion. This case is a severe and unusual form of the neuro-psychiatric disorder, somatoparaphrenia. The relationship of this condition to other disorders of parietal lobe function is discussed.
Multiple sclerosis (MS) is very uncommon among ethnic Asians in the Indian subcontinent, among Asians and Africans resident in the New Commonwealth countries of Africa and in the West Indies. It is also very uncommon among those who have migrated to England from those countries. In contrast, the children born in the United Kingdom of Asian, African and West… (More)
Botulinum toxin inhibits acetylcholine release and therefore could cause mydriasis. We report a case of acute angle-closure glaucoma which occurred shortly after a series of injections of botulinum toxin round the eyelids for blepharospasm.
A trial of n-3 polyunsaturated fatty acids in the treatment of multiple sclerosis has been conducted over a 5 year period. Ambulant patients (312) with acute remitting disease were randomly allocated to treatment or placebo. Both groups were given dietary advice to increase the intake of n-6 polyunsaturated fatty acids and the treatment group in addition… (More)
BACKGROUND A relation between migraine with aura and cardiac right-to-left shunts has been reported. Right-to-left shunts are also associated with stroke and certain forms of decompression illness. We investigated the effect of closure of right-to-left shunts on migraine symptoms. METHODS A consultant neurologist, who was unaware of information about… (More)
People with dementia or delirium have increased mortality in the 6 months after hip fracture, but depression might take longer to have an effect. We assessed the psychiatric status of 731 participants with hip fracture and analysed the effect of psychiatric illness on mortality during the next 2 years. We found that dementia, delirium, and depression all… (More)
We have amplified and sequenced DNA in the envelope (env) and long terminal repeat (LTR) regions of human T-cell lymphotropic virus type I (HTLV-I) proviruses from the peripheral blood of 10 HTLV-I-seropositive patients with tropical spastic paraparesis (TSP) and two patients with adult T-cell leukemia. The aim was to examine variation in these regions and… (More)
In six patients with episodic, severe, and disabling headaches with specific characteristics and in whom clinical examination and CT scanning were normal the symptoms were due to hindbrain herniation into the foramen magnum with resulting craniospinal pressure dissociation. This syndrome may be recognised by eliciting the typical history. In all patients… (More)
