[Normal pressure hydrocephalus in geriatric patients--a treatable form of dementia].

Six geriatric patients are presented who were treated because of normal pressure hydrocephalus. A tentative diagnosis was made if dementia, gait disturbance, and incontinence together with a typical CAT-scan were present. In these cases an operation was carried out.

[Radiation treatment of intracranial arteriovenous malformations--experiences with a semi-stereotactic technic].

Since 1982 79 patients with intracranial AVM's were irradiated at linear accelerator with 10 MV photons. Diagnosis, localization and therapy were done immobilizing the head for identical positioning. In a controlled study the therapy was done with fractionated irradiation up to 50 Gy in 25 fractions within 5 weeks or with 20 Gy in 4 fractions within 7 days.

Prevention of symptomatic vasospasm after SAH by constant venous infusion of nimodipine.

Sixty-one patients with SAH due to rupture of a cerebral aneurysm, classified in Grades I to IV according to Hunt and Hess, received a constant venous infusion of Nimodipine in a dose of 2mg/h for at least 14 days, followed by an oral administration of 60 mg/6 h for at least 4 days. Patients admitted after the 6th day of SAH, patients with SAH but without aneurysm on the angiogram and patients in Grade V were excluded. Mortality in 30 patients of Grades I-II was 3.

Intracarotid slow bolus injection of nimodipine during angiography for treatment of cerebral vasospasm after SAH. A preliminary report.

Nimodipine was given as an intracarotid slow bolus injection in six patients with subarachnoid hemorrhage (SAH) due to rupture of a cerebral aneurysm, with angiographically demonstrated vasospasm. The patients were followed by serial angiograms for demonstration of the effect of nimodipine on vasospasm. After angiography, all patients were treated with a constant venous infusion of this new calcium antagonist.
