Abstract
A randomized, double-blind study of procaine/haematoporphyrin (KH3) has been carried out over two years in a selected population of healthy elderly subjects. The period of study exceeds 500 patient years. The trial population was weighted to contain a larger proportion of subjects aged over 75 years than a standard population; those receiving active KH3 had similar characteristics on entry to those receiving placebo. Over the course of two years, KH3 was shown to be an active substance in that: (a) decrement in the consolidation of new learning was prevented in the treatment group (P P P <0.005).Keywords
