Objective: To determine the efficacy of cognitive stimulation therapy (CST) in the treatment of neuropsychiatric symptoms in patients with Alzheimer's disease. Design: A randomized, controlled, rater-blind clinical trial. Setting: The military sanatorium. Subjects: Thirty-two patients with mild to moderate Alzheimer's disease exhibiting marked neuropsychiatric symptoms were included in the study. Intervention: All 32 patients were randomly assigned to a cognitive stimulation therapy group (n = 16) or a control group (n = 16) for 10 weeks. Main measure: The efficacy measures included the Mini Mental State Examination and the Neuropsychiatric Inventory. Results: Patients receiving cognitive stimulation therapy showed a greater improvement in the Neuropsychiatric Inventory total score (mean change -2.06 points versus 0.00 points, t = -4.766, P<0.001) and in the Mini Mental State Examination total score (mean change 0.81 points versus -0.19 points, t = 3.106, P = 0.004) compared to control at week 10. Analysis of the individual Neuropsychiatric Inventory domains revealed a statistically significant benefit for cognitive stimulation therapy-treated patients in the areas of apathy (mean change -1.06 points versus -0.31 points, P = 0.017) and depression/dysphoria (mean change -0.50 points versus 0.06 points, P = 0.047). There were no statistically significant benefits for cognitive stimulation therapy-treated patients in the other individual Neuropsychiatric Inventory domains or in the caregiver distress score. Conclusions: Cognitive stimulation therapy has significant efficacy in lowering apathy and depression symptomatology and in the Mini Mental State Examination in patients with mild to moderate Alzheimer's disease.
