Humor therapy can be as effective as some drugs in managing agitation in dementia patients. That’s according to research at the University of New South Wales in Australia. The study examined the effectiveness of professional humor therapists, called Elder Clowns, who work with nursing home staff trained in the practice, called Laughter Bosses. They performed weekly humor sessions with individuals and groups of patients, using methods based on improv comedy — much like Clown Doctors, who work in children’s hospitals to lift the mood of the patients and increase interaction.
