For unknown reasons, there is a greater increase in the risk for cardiovascular complications in diabetic women than in diabetic men. Our aim was to study gender-related differences in the mechanical properties of the great arteries in patients with insulin-dependent diabetes mellitus (IDDM) but free from known cardiovascular and cerebrovascular(More)
The mortality rate has recently been reduced to only a small percentage of patients selected for early aneurysm surgery. Despite recovery without neurological deficits, however, a diffuse encephalopathy may remain, with emotional and psychological sequelae that will interfere with rehabilitation and social reintegration. The present study evaluates quality(More)
Does early aneurysm operation, while lowering the overall management mortality, result in an unacceptable morbidity in terms of increased cognitive disturbances and psychosocial maladjustment? The present study evaluates quality of life, degree of cognitive dysfunction, and adjustment of 93 patients with satisfactory neurological recoveries after operations(More)
Twenty patients who underwent early aneurysm surgery--that is, surgery within 72 hours after rupture--underwent further follow-up examination including magnetic resonance imaging (MRI) of the brain and a comprehensive neuropsychological assessment. Significant statistical correlation between tissue loss as seen on a late MRI scan and neurobehavioral(More)
Seventy-eight individuals among a population of 1.46 million suffered aneurysmal subarachnoid hemorrhage (SAH) during 1983. Within 24 hours after the bleed, 32 of the 78 patients were in Hunt and Hess neurological Grades I to II, 13 were in Grade III, 21 were in Grades IV to V, and 12 were dead on admission to a hospital or forensic department. When the(More)
Four women, aged 39 to 46 years, were urgently admitted to our neurosurgical unit after strokes. On admission, all appeared moribund, presenting with deep coma, pupils bilaterally dilated and fixed, decerebrate posture, and markedly abnormal respiratory patterns. Computed tomography revealed subarachnoid hemorrhage with an associated large intracerebral(More)
Twenty patients, who had sustained a proven subarachnoid haemorrhage (SAH) and in whom cerebral panangiography had failed to reveal any source of the bleeding (SAH-NUD), were subjected to a neuropsychological examination involving memory functions, spatial perceptual organization, visuoconstructive abilities, reasoning, perceptual speed and accuracy, and(More)
The discouraging history associated with management of aneurysmal subarachnoid haemorrhage (SAH) is reviewed along with improvements in outlook attributable to progress made within the past decade. Among the new developments is the introduction of microsurgical techniques that allow elective surgery in the acute stage thereby preventing repeat haemorrhages.(More)
OBJECTIVE Many patients exhibit cognitive disturbances after aneurysmal subarachnoid hemorrhage (SAH). Structural and functional neuroimaging has failed to demonstrate any correlation with these complaints. This study was performed to investigate whether neuropeptide concentrations in cerebrospinal fluid could be related to cognitive disturbances after SAH.(More)
