In recent years, the trend of my country's population aging has intensified, and the number of elderly people has increased sharply, which has caused greater pressure on society and families. The physical and mental health of the elderly has an important impact on their daily lives.

The research and analysis found that the types of mental illness in the elderly mainly include twilight psychology, inferiority complex, worthlessness, restlessness, mental disorders, and psychosis. The reason for the formation of twilight psychology is the influence of factors such as the children of the elderly leaving home, infirmity, and other factors, which lead to the loss of the joy of life in the elderly, negative and pessimistic emotions about the future, and a negative and negative gray psychology [4,5]. Inferiority psychology will lead to complaints and acute responsibilities for children in the elderly. The inferiority complex is mainly due to the reduction of economic income, social status, and role changes in the elderly after retirement from their original jobs, followed by the formation of psychological problems. Disappointment and an inferiority complex. The sense of worthlessness means that the elderly cannot adapt to a leisurely life, cannot reasonably arrange their own time, and gradually think that they have become a burden on the family and society, unable to find the value of their own existence, and then have a negative and low evaluation of themselves. Uneasiness is caused by the elderly due to self-enclosed, Unable to communicate with society and others, they gradually develop a feeling of loneliness and helplessness and a fear of the outside world.

At present, about 85% of the elderly in my country have different degrees of psychological problems, and more than 20% have significant psychological disorders such as depression and anxiety. The number of patients with Alzheimer's disease has reached 0.75%. Factors such as children leaving home as adults and forming new families have led to an increasing number of empty-nest elderly in my country. More and more elderly people are unaccompanied in their lives, and their lives are very lonely and monotonous [7]. The gradual transfer of the young rural population to the city has seriously affected the medical care, entertainment, and quality of life of the rural elderly population, and their physical and mental health will have varying degrees of problems.
