Animal-Assisted Therapy in Elderly Patients: Evidence and Controversies in Dementia and Psychiatric Disorders and Future Perspectives in Other Neurological Diseases.

Animal-assisted therapy (AAT) includes a set of nonpharmacological interventions aimed at improving human health through the use of trained or untrained animals. In recent decades, AAT has been trialed for different neurological and psychiatric disorders. In patients with dementia, interaction with animals seems to have a positive influence on aggressiveness and anxiety and to ameliorate quality of life and relationship skills. In psychiatric patients, AAT seems to increase motivation and self-esteem, improve prosocial conduct, and decrease behavioral problems. The aim of this study is to review the literature on AAT for elderly people with dementia and psychiatric disorders. Other fields of possible application for AAT are suggested.
