Effectiveness measurement of familiar songs method by means of electroencephalography

Using the electroencephalography measurement, it was proved that the "familiar songs method", a method of music therapy, was effective enough to improve the arousal level of senile dementia. The frequency analysis of the electroencephalography shows that crests were observed in the a wave region before the music program, and the crests were lowered or shifted to the /spl beta/ wave region before and after singing the familiar songs, The result shows that the arousal level is increased by the familiar songs method.
