We all know that Alzheimer’s disease is a disease caused by aging and lesions in the brain, and it is not the same as what we often call mental illness. However, it can be deduced that the mental activity of a person is linked to the brain function, and Alzheimer’s is also linked to the brain function. For example, when a person gets old and retires, he or she often feels a sense of loss mentally. They feel that they are not the same as before, that no one listens to their words, that no one is around them anymore, that their status in the family and society has decreased, that their ability to work and live is not as good as before, that their financial income is less, that their health is often in trouble, and that if they are not open-minded, they will inevitably become depressed and moody. At the same time, in old age, it is also easy to have illness, the departure of relatives, the departure of children, loneliness, and the stimulation of some unfavorable factors in life, such as keeping an empty nest by oneself, which can promote the occurrence of dementia. The first time I saw him, I was very happy with his life. For this sudden event, Li DaBu at first hard to accept, and then began to blame himself. He felt that he did not take good care of his partner in the past, did not discover her illness in time, did not give her treatment, and let her go so early. He was depressed and restless all day long, and always sighed when he thought back to the past. The son was afraid that he would be alone at home with his thoughts, so he asked to be relieved of his past, but Uncle Li did not want to go out and stayed at home all day. The son had to move in with him. Soon, Uncle Li’s son found that his father was not only in a low mood and slow to react, but his memory had also declined. Often can not remember what just happened, sometimes the date can be remembered wrong, sometimes chatting and talking suddenly can not remember the name of the former colleague. When his grandson comes home on weekends, he often doesn’t remember, so his son has to remind him that it’s time for the weekend and his grandson is coming to see him, and only then does Uncle Li have a smile on his face. Everyone thought that Uncle Li might be in a bad mood because his partner had just left, and that he would get better after a while. However, Uncle Li’s memory is getting worse and worse, and he is making more and more mistakes. Once, Uncle Li went out to buy vegetables and came back to find that he forgot to turn off the tap when he left, and the floor of the house was covered with water, and the wooden floor was also soaked. Uncle Li is more self-blame, restless, think they are useless, can not do things, become more depressed, always worried about their faucet did not turn off, to check several times. And afraid of their poor memory, can not remember things, what else can go wrong. He walks around the house, fidgets, gets upset and loses his temper easily. The son saw his father’s appearance and was worried, so he took him to the doctor, who gave Uncle Li some medication for depression and anxiety. After returning home, Uncle Li insisted on taking the medication, and after more than 1 month, his mood improved significantly. However, what worries Uncle Li’s son is that Uncle Li’s memory is still very poor. Uncle Li’s son had taken him to the doctor, who said that Uncle Li might be suffering from Alzheimer’s disease, which is still in its early stage. Ans: As we can see in this example, Uncle Li was first in a bad mood due to the death of his partner, and gradually he also developed memory loss, which in turn aggravated his mood changes. When his mood improved after treatment, his memory did not improve with it. Moreover, the doctor also said that Uncle Li was suffering from Alzheimer’s disease. We can also see in our life that Alzheimer’s disease, in addition to the decline of intelligence, often shows some psychological behavioral symptoms, such as, paranoia, irritability, walking around aimlessly, asking the same one question over and over again, and even aggression, bickering, and hitting, cursing, and destroying things. Among these psychological symptoms, depression is the most common, and anxiety is also a common symptom, sometimes in combination with other symptoms. Generally speaking, elderly people are more introverted and conservative, prone to depression, stubbornness and suspicion, which often play a role in accelerating the aging process of the elderly. In this way, the physical aging and psychological restlessness of the elderly form a vicious circle. It can also be understood that people’s physical aging tends to produce psychological depression, anxiety, irritability, etc.; and these bad psychology in turn promotes this aging. As we all know, nowadays, medical science often talks about “physical and mental diseases”, which means that physical diseases are often psychologically related, and the treatment of diseases nowadays also pays more attention to the role of psychological treatment. Similarly, Alzheimer’s disease is also related to psychological factors, so the treatment should also focus on the use of psychotherapy to eliminate their bad psychology, stabilize their emotions, and have enthusiasm and confidence in themselves and their lives. For example, we often see some Alzheimer’s patients change to a new living environment and their condition often worsens. Because the elderly people are less able to adapt to new environment, less able to learn new things, and less able to accept new people and things are inferior. Therefore, if they are given a new environment and new caregivers, they often cannot adapt and accept it, and will show irritability for a period of time at first, which may even affect his eating and sleeping. According to new research on the subject, people who often have negative emotions such as pessimism, anxiety and depression may be more likely to get Alzheimer’s disease than people with positive attitudes. Therefore, for the majority of elderly people, in addition to paying attention to their physical health, they must also pay attention to their psychological adjustment and maintain their mental health, which can slow down our aging. We can make some attempts in our daily life: keep an open mind; forget our age and contact more fresh things; insist on activities and live in a rhythm; enjoy ourselves and enrich our life in old age.
