title: A placebo-controlled study of pyritinol ('Encephabol') in dementia.
abstract: A double-blind, placebo-controlled trial was carried out on 40 patients suffering from moderately advanced dementia. The patients were allocated randomly either pyritinol (800 mg daily) or identical placebo for 3 months. Assessments using a modified Crichton Geriatric Behavioural Rating Scale were made pre-treatment and monthly up to 3 months, and then at follow-up at 6 months. Patients on pyritinol showed significantly higher levels of improvement than did those on placebo. Laboratory tests conducted throughout remained within normal limits for both groups.
