Research Title: Effects of laughter therapy on depression, cognition and sleep among the community-dwelling elderly
Aim of the research: To investigate the effects of laughter therapy on depression, cognitive function, quality of life, and sleep of the elderly in a community.
Methods: Between July and September 2007, the total study sample consisted of 109 subjects aged over 65 divided into two groups; 48 subjects in the laughter therapy group and 61 subjects in the control group. The subjects in the laughter therapy group underwent laughter therapy four times over 1 month. We compared Geriatric Depression Scale (GDS), Mini-Mental State Examination (MMSE), Short-Form Health Survey-36 (SF-36), Insomnia Severity Index (ISI) and Pittsburgh Sleep Quality Index (PSQI) between the two groups before and after laughter therapy.
Conclusion: Laughter therapy is considered to be useful, cost-effective and easily accessible intervention that has positive effects on depression, insomnia, and sleep quality in the elderly.

I have always felt that laughter in the face of reality is probably the finest sound there is and will last until the day when the game is called on account of darkness. In this world, a good time to laugh is any time you can. -- Linda Ellerbee
