Abstract

Objectives
Cognitive intervention treatment is known to be effective among dementia patients. To establish an effective nonpharmacological treatment for dementia patients, it is necessary to study how it affects not only cognitive function but also emotional function as well as daily life abilities. This study examined the effects of a cognitive intervention program using the robot PIO.
Methods
The robot-mediated cognitive intervention using “laughter-PIO” was applied to 36 participants rated Clinical Dementia Rating 0.5 or 1. The cognitive function, emotional state, and daily life abilities were evaluated before and after the program.
Results
After the cognitive intervention, the Geriatric Depression Scale-Korean score improved from 11.6 ± 6.3 to 9.0 ± 6.0 (p = 0.03). The subtests of the Korean version of the Consortium to Establish a Registry for Alzheimer’s Disease Assessment Packet, J2 Boston Name test, J3 Mini-Mental State Exam, and J7 Word Recognition test, showed significant improvements (p < 0.05). The Digit Span Test result increased from 13.1 ± 5.4 to 15.2 ± 6.1 after the program (p < 0.05).
Conclusions
The cognitive intervention program using the robot “PIO” improved cognitive function and the emotional state of dementia patients, and daily life abilities.
