Background and Purpose: The effect of cognitive intervention in patients with dementia is inconsistent. This study sought to find out the effect of cognitive intervention by measuring interval change between before and after intervention.
Methods: We evaluated cognitive changes according to clinical diagnostic group across Gangwon province for 940 patients with dementia diagnosed at hospital clinics and 2,975 subjects without dementia. All subjects were treated with cognitive intervention. They underwent a cognitive and mood assessment before and after intervention. We used interval change of Mini-Mental State Examination (MMSE) scores as a primary measure of interventional outcome.
Results: Changes in mean MMSE score were significantly different between the non-dementia group and the dementia group (p=0.016), with changes of 0.7±2.4 and 1.0±3.7 points (±standard deviation), respectively. Cognitive improvement regarding completion of session was significantly higher in the dementia group (p=0.001), with changes of 0.41±4.51 for uncompleted group and 1.30±3.22 points for completed ones. Lower initial MMSE scores, lower age, and type of intervention were found to be independent predictive factors of subsequent cognitive changes as indicated by mean MMSE scores.
Conclusions: These findings suggest that cognitive intervention might be useful for patients with dementia. Their response to treatment might be related to the type of intervention.
