Notes:
Forty patients with probable Alzheimer's disease (AD) were selected from a pool of 80 patients and assigned to 4 groups. Each received either social support, cognitive training only, or cognitive training in combination with pyritinol or phosphatidylserine. Treatment duration was 6 months. Before and after treatment the patients underwent neuropsychological testing as well as measurement of the regional cerebral metabolic rate for glucose using positron emission tomography (PET) and 2[18F]-fluoro-2-deoxy-D-glucose (FDG). Before treatment, the groups were comparable in respect to resting and activated glucose pattern achieved by a visual recognition task. They did not differ in scores of a neuropsychological test battery. After the treatment period the group with cognitive training + phosphatidylserine showed a significant glucose enhancement during the stimulation tasks in various brain regions, and an improvement in cognitive functioning compared to the other groups. The group with cognitive training + pyritinol had better stimulation effect as that of the social support group indicating that a combination of cognitive training + pharmacological intervention was superior than that of cognitive training alone.
