Nimodipine in the treatment of old age dementias

Abstract

1. In a multicenter, placebo-controlled, double-blind clinical study in 178 elderly patients with cognitive decline, nimodipine, a calcium antagonist was found to be a therapeutically effective agent in the treatment of old age dementias. 2. Treatment with 90 mg of nimodipine administered orally in divided doses for 12 weeks was significantly superior to an inactive placebo on all outcome measures including the Wechsler Memory Scale, the Mini Mental State Examination, the Global Deterioration Scale, the Sandoz Clinical Assessment Geriatric Scale, the Plutchik Geriatric Rating Scale, the Severity of Illness and Global Improvement Scales of Clinical Global Impression, and the Hamilton Psychiatric Rating Scale for Depression. 3. Adverse effects with nimodipine were few and mild. The drug was equally well tolerated and equally effective in the two major dementias of old age, i.e., primary degenerative and multi-infarct. The number of abnormal laboratory test readings remained essentially unchanged from pre-treatment to post-treatment.
