What Researchers Did
Researchers reviewed various drug treatments that were being explored in 1981 for age-related cognitive decline.
What They Found
They identified cerebral vasodilators, Gerovital H3, psychostimulants, "nootropics," neuropeptides, and neurotransmitters as substances under investigation. The understanding of cognitive decline had shifted, recognizing it often occurs independently of arteriosclerotic vascular changes. Substances affecting brain electrical activity, neurohumoral processes, or central neurotransmitters were showing early promise.
Canadian Relevance

Study Limitations
As an overview from 1981, this study provides a historical perspective but lacks specific clinical trial data or definitive treatment outcomes.
