Randomized Controlled Trial of Multi-Component Cognitive Stimulation Therapy (SADEM) in Community-Dwelling Demented Adults.

BACKGROUND Dementia is a persistent, progressive state of cognitive decline against which pharmacological intervention has a modest efficacy, reducing behavioral but not cognitive symptoms. Therefore, different non-pharmacological therapies have been developed; the most scientifically recognized are cognitive therapies that have improved cognitive function and daily life activities. OBJECTIVE To evaluate the effectiveness of a multicomponent cognitive stimulation therapy (SADEM) on cognitive and behavioral function and daily life activities in patients with mild stage dementia. METHODS Controlled clinical trial with pre- and post-intervention (12 months) and follow-up (24 months after) evaluations. Participants (67) diagnosed with mild dementia were randomly assigned to intervention group (n = 39) or control group (n = 28). The intervention took place throughout one year and consisted of two weekly 90-minute sessions and one more a year after a monthly follow-up. Instruments were used to evaluate outcomes in cognitive, behavioral, and affective domains. RESULTS The results showed statistically significant differences, with improvement in the cognitive outcomes and the Dementia Index post-intervention (p = 0.01). No progression of the disease was observed at the end of the study. CONCLUSION The multicomponent intervention tested had positive effects on cognitive and behavioral functions and daily life activities in people with mild stage dementia, delaying progression for at least two years.
