Useful though controversial, Dolphin Assisted Therapy (DAT) appeared in Florida, USA in the 1970s and 1980s at seaside amusement parks as an outgrowth of animal performances and the postive reactions of guests.
More recently, ocean resorts have grown up around the DAT phenomenon, often with large accomodations and entertainment fees levied for stay near the dolphin facilities. DAT has become part of a high-priced Travel and Tourist attraction in some areas of the US, but a certain number of people gain real benefits form DAT, no matter the costs.
DAT facilities advertise that the treatments are effective agasint neurologial disorders and learning disabilities, cerebral palsy, depression, and other conditions. Since the 1980s, wounded veterans are also responding well to DAT.
