Robot Therapy for Prevention of Dementia at Home – Results of Preliminary Experiment

In robot therapy for senile dementia patients, a seal-like robot, Paro, was left in patients’ homes for a week to determine its neuropsychological influence. Efficacy was evaluated by the diagnosis method of neuronal dysfunction (DIMENSION), which detects a lack of smoothness of scalp potential distribution resulting from cortical neuronal impairment by analyzing recorded a patient’s electroencephalogram (EEG). Interaction with Paro by patients was observed by their families. In a preliminary experiment, 5 subjects were studied after informed consent was received from them or their families in accordance with the medical ethics committee of the University of Tsukuba and the AIST ethics committee.
