[Psychometric evaluation of the effects of an almitrine-raubasine combination in the intellectual deterioration of aged subjects. A double-blind controlled trial versus placebo].

The clinical and psychometric evaluation of a drug to be used against the intellectual deterioration associated with cerebral aging is of obvious interest when carried out on ambulatory subjects, since the symptoms likely to be reduced are found in elderly people usually living at home. Thirty-six patients (18 male, 18 female; mean age 65.5 +/- 1.7 years) were selected and allocated at random to two treatment groups. They received during 2 months 80 drops per day in two doses of either an almitrine-raubasine combination or a placebo. Patients definitely entered the trial when Hachinski's score for ischaemia was equal or inferior to 7. They were evaluated at zero, 1 and 2 months by means of 3 performance tests (Toulouse-Pieron test, Tapping test, numbers memorization test) and 2 mood tests (Hamilton's scale, Zung's questionnaire). All mean scores of recognition tests were statistically improved in the almitrine-raubasine group after 2 months of treatment. Compared with the placebo group, the improvement in the almitrine-raubasine group was significant at 1 month for 3 medium scores (symbols omitted, taping, numbers in normal order) and for all scores at 2 months. The psycho-behavioural symptoms evaluated by the two mood scores were significantly improved in the almitrine-raubasine group (P less than 0.001) and in comparison to the placebo group after 1 and 2 months (P less than 0.001). These results concerning intellectual performance and mood demonstrate that the almitrine-raubasine combination is useful in the treatment of intellectual deterioration in elderly people living at home.
