Your mother's age, coupled with incentives, this situation is best to see a psychiatrist. If the doctor suggests taking medicine, you can take it for a while. There are also patients who choose to take Chinese medicine, which depends on everyone's specific situation.
Taking medicine is one aspect, so is psychological counseling. You can find a psychological counselor for professional counseling. Generally, if there are local universities, junior colleges and technical secondary schools, these schools will have psychological teachers, and they are generally qualified. If they are willing to help, it is best to recommend some useful institutions or experts, even if they are unwilling to help. Psychological teachers don't charge students fees on campus, but they also don't charge fees depending on the teacher. If none of these schools exist, there are high schools, junior high schools and primary schools. You can ask someone else.
In addition, we should care about the mother's daily life and let the elderly bask in the sun. It is best for the elderly to live in a clean and bright room, draw the curtains when sleeping, eat some apples, bananas and melon seeds (all of which help the brain to regulate emotions), let the elderly communicate with their peers, and let the mother's friends persuade them more. You can also let the elderly contact some faith churches, such as Catholicism, so that the elderly feel warm and have a little spiritual sustenance.
But the key still depends on the doctor's diagnosis, whether to take medicine and psychological counseling, and others are only auxiliary.
