The occurrence of photosensitivity (PS) was examined in 327 Arabs greater than or equal to 15 years of age with epilepsy by intermittent photic stimulation (IPS). A control group of 192 nonepileptic Arabs greater than or equal to 15 years of age were also examined by IPS. Of the epileptic patients, 24 (7.3%) were photosensitive, an incidence comparable to(More)
We studied the pattern and outcome of strokes in 200 Saudi patients. Cerebral infarction constituted 87% of strokes, subarachnoid hemorrhage 4.5%, cerebral hemorrhage 6.5%, and venous infarction 2%. The vessel most commonly involved was part or all of the middle cerebral artery, constituting 52% (90) of the 174 arterial infarcts. Lacunar infarcts were seen(More)
We describe 6 patients with ophthalmoplegia, ataxia and normal or exaggerated deep tendon reflexes. All had been preceded by a febrile illness and had a full recovery without sequelae. The brainstem auditory evoked potentials showed a localised lesion in the upper brainstem while the pattern shift visual evoked potentials were normal and did not show any(More)
Evoked potential audiometry and brain-stem auditory evoked potentials were evaluated in 15 patients with systemic brucellosis in whom brucella meningitis was suspected clinically. In 8 patients cerebrospinal fluid (CSF) was abnormal with high brucella titre, and evoked potentials were abnormal in all of them. In 7 patients the CSF was normal and evoked(More)
To obtain data about the size of the third ventricle, the lateral ventricles, and the cortical sulci in dementing diseases, computed tomography was performed on 300 patients over 60 years of age. Half of these patients were demented; half were not. Measurements were made to determine the width of the third ventricle, the Huckman number, the ventricular(More)
Six patients (three males and three females), mean age 35.2 years (range 31-43 years), with extensive venous thrombosis were studied. Initial laboratory data indicated that all patients had normal antithrombin III (ATIII), four patients had low protein C (PC), three patients had low protein S (PS) and two patients had low plasminogen. Four patients had high(More)
One hundred and two stroke patients were studied. Thirty-three (32 per cent) were hypertensive by the WHO criteria. Eighty-three (83 per cent) had cerebral infarction and three patients suffered from spontaneous intracerebral haemorrhage. The mean left ventricular mass was calculated from echocardiographic measurements and compared with that of controls.(More)
