Choreo-athetosis and encephalopathy induced by phenytoin.

Two patients with intractable epilepsy who had been treated with various combinations of anticonvulsant drugs developed phenytoin encephalopathy. In both patients choreo-athetoid involuntary movements were prominent. Blood phenytoin concentrations were above 30 mug/ml. When phenytoin was given in smaller doses and its level in the blood fell the involuntary movements and other clinical manifestations disappeared.

Periaqueductal dysfunction (the Sylvian aqueduct syndrome): a sign of hydrocephalus?

A patient with hydrocephalus due to aqueductal occlusion is described in whom the Sylvian aqueduct syndrome appeared during a sudden increase in intracranial pressure. The ocular signs resolved completely when the hydrocephalus was relieved. Marked dilatation of the posterior part of the third ventricle and of the rostral aqueduct with axial displacement of these structures was demonstrated radiologically. It is suggested that the ocular signs in this case were the result of periaqueductal dysfunction due to assimilation and dilatation of the aqueduct, with secondary tentorial block. This abnormality may be the cause of the similar abnormalities commonly found in noncommunicating hydrocephalus in both infants and adults.

Effect of chocolate in migraine: a double-blind study.

The effect of chocolate on a group of volunteer migrainous subjects, who had observed that headache regularly occurred after the ingestion of small amounts of cocoa products, was investigated. Two separate studies were carried out in a double-blind placebo controlled manner. Only 13 headaches occurred to chocolate alone in 80 subject sessions, and only two subjects responded consistently to chocolate in the two studies. This suggests that chocolate on its own is rarely a precipitant of migraine. Other possible implications of the results are also discussed.

Differential diagnosis of transient amnesia.

In a group of 39 consecutive patients attending neurological clinics with transient amnesia patients with transient global amnesia formed the largest group; others suffered from epilepsy, migraine, temporal lobe encephalitis, or psychogenic fugues. In most cases the clinical features suggested the aetiology, but an electroencephalogram recorded as soon after the attack as possible may help in distinguishing amnesia due to temporal lobe epilepsy.
