Forty patients aged 65-80 with minor-medium signs of brain aging were treated for 6 months with daily 90 mg doses of nimodipine. Treatment was well tolerated in that the minor side effects reported by a few of the patients never required withdrawal of the drug. Treatment proved useful, as shown by a variety of mental tests, in 69.5% of cases. In 20% conditions remained unchanged and in 9.5% further deterioration was observed. The authors conclude that nimodipine may be considered a useful therapeutic resource for phenomena of brain aging.
