Animal-assisted Therapy Improves Cognitive and Emotion in Nursing Home Residents

More than 80% of the residents of the investigator\'s nursing home are dementia, who are often mentally and emotionally unstable. The staff need to spend time helping to eliminate problems. The investigator assume that non-drug intervention measures can be added, such as the Animal-assisted Therapy (AAT). The hypothesis for ATT is expected to improve the mental and emotional inappropriate manifestations of dementia, reduce interfering behaviors, improve the quality of life, reduce the use of inappropriate mental drugs, and expect residents to delay the degradation of physiological functions.
