Alzheimers disease (AD) is a chronic neurodegenerative disease that represents the most prevalent cause of dementia in older adults. The progression of cognitive and functional deficits in AD leads to dependence and is associated with significant caregiver burden. Currently available treatments aim to alleviate cognitive and functional loss, in addition to behavioral symptoms that are expected to occur in the course of the disease. The objective of the present study is to evaluate the effect of a multiprofessional cognitive and functional stimulation program for patients with mild and moderate AD. The study was conducted at the Rehabilitation Center and Day Hospital, Institute of Psychiatry, Hospital das Clínicas, Faculty of Medicine, University of Sao Paulo. The control group consists in a subset of patients with AD to whom no such intervention was provided. Both groups have received regular outpatient treatment and were stably medicated with antidementia drugs. Patients and controls were evaluated before and after the intervention by two raters who were blinded to treatment groups. The intervention took 15 weeks, with two six hours weekly meeting (a total of approximately 180 hours). Outcome measures were modifications in cognitive, functional, mood and quality of life ratings. The assessment consisted in: Short Test of Cognitive Performance (SKT), Mini-Mental State Examination (MMSE), Direct Assessment of Functional Status (DAFS), Geriatric Depression Scale (GDS), Neuropsychiatric Inventory (NPI) - caregiver subscale, Quality of Life in Dementia (QoL-AD), and Clinicians Interview Based Impression of Change (CIBIC-Plus). Results: whereas patients in the intervention group remained cognitively stable, patients in the control group displayed a mild but significant decline, as indicated by the total SKT score (p=0.05) and the attention STK subscore (p=0.01). No significant differences were observed in functional performance (DAFS) and neuropsychiatry symptoms (NPI), irrespective of treatment groups. Patients in the intervention group displayed improvement in depressive symptoms (p=0.002) and quality of life measures (p=0.01). As for the CIBIC-Plus, both patient- and informant-based questionnaires indicated a significant improvement in memory (p=0.01 and p=0.05, respectively), in addiction to a significant improvement in the patient-based assessment of orientation (p=0.05), and in the informant-based assessment of sleep and praxis (p=0.05 and p=0.03 respectively). In conclusion, evidences were provided that the present program of cognitive and functional stimulation may yield mild but relevant benefits for patients with AD. Global impressions of change in memory, orientation, sleep and praxis, in addition to improvement in quality of life and depressive symptoms, were the most sensitive measurements in the present schedule.
