Cognitive Stimulation in Patients with Dementia: Randomized Controlled Trial

Background/Aims: This study explores the effective outcomes of a structured cognitive stimulation treatment to improve cognition and behavioral symptoms in people with dementia (PWDs), using a randomized controlled clinical trial. Methods: Thirty PWDs were divided into three groups: experimental (treated with cognitive stimulation), placebo (treated with occupational therapy), and control (continuing with the usual activities of the nursing home). Assessment, at baseline and after a period of 8 weeks, was performed using the Clinical Dementia Rating Scale, activities of daily living, Mini-Mental State Examination, Esame Neuropsicologico Breve 2, Geriatric Depression Scale and Behavioral Pathology in Alzheimer’s Disease Scale. Results: Only the experimental group improved its performance in cognitive tests (p < 0.05) and showed a significant decrease in behavioral symptoms (p < 0.01) after the treatment. Conclusions: The results suggest that a cognitive stimulation treatment for PWDs would improve not only their cognition, but also behavioral symptoms
