Memory impairment is the main clinical manifestation of Alzheimer’s disease. In the early stage, the patient’s memory is impaired in recent events (cannot remember recent events), in the middle stage, distant memory is impaired (cannot remember previous events), and in the late stage, memory is completely lost (cannot remember anything, and cannot even recognize their closest family members). For memory impairment, in addition to taking puzzle drugs under the knowledgeable guidance of a doctor, appropriate memory training can be performed to maintain the patient’s original memory as much as possible and to delay further memory decline. Memory not only plays a great role in a person’s work, study and life, but is also an important means to ensure human health and slow down brain aging. Memory training is called “gymnastic exercise” for brain cells. Regularly doing this “gymnastics” can prevent brain aging, is a good recipe for brain health. Epidemiological surveys have found that the incidence of Alzheimer’s disease is significantly lower among the elderly with high literacy than those with low literacy, and low literacy is a risk factor for Alzheimer’s disease. Most of the people who are good at brain movement and diligent in memory have normal results of head X-ray tomography (CT) examination even though they are old. Some people who are lazy and don’t pay attention to moving for a long time, although they are in their prime, head CT examination shows obvious signs of brain atrophy such as widening of the subarachnoid space and brain sulcus, thinning of the cerebral cortex and enlargement of the ventricles. For memory training in Alzheimer’s patients, we should focus on the process of training rather than the result of training. That is, we do not necessarily want the patient to remember much, but rather to have the patient participate in the training and use his or her brain. During memory training, the difficulty of memory should not be too high and should be arranged according to the actual situation of the patient. If the difficulty is too high, on the one hand, the patient is unable to complete; on the other hand, it increases the patient’s mental burden and causes adverse emotional reactions; coupled with the patient’s reduced judgment due to mental retardation, the patient not only refuses to cooperate with the training, but some may even trigger mental and behavioral disorders. 1.Alzheimer’s disease patients whose memory damage is obvious but not very serious. If the patient usually likes to read newspapers, books and TV, as long as the patient is still willing to read, don’t restrict or stop him, but also encourage him to read, although the patient may not be able to read or remember. If the patient likes to play cards or mahjong, when the patient has not completely lost his interest and ability in this area, he can find a few people free to play with him, but do not care if the patient plays well or badly. Of course, as long as the patient is willing, you can also play some simple intellectual games with him, such as playing flying chess, counting 24 points, and doing uncomplicated puzzles. 2. For patients with serious memory impairment, put some simple and eye-catching objects in their rooms that are useful in daily life, such as calendars, clocks, various toys, etc. Teach them every day what day it is, establish a regular time of life, tell them when to get up, go to bed, eat, take medication, take a bath, etc., so that long-term targeted training can be conducted to strengthen their memory. For the names of some items, repeat them 3 to 5 times a day, and reward those who answer correctly with some small food or handkerchiefs and other items to consolidate interest in memory. If the answer is wrong, the number of times of learning will be increased and the child will not be allowed to go out. When doing reinforcement memory training, the caregiver must be kind and patient, and should not reprimand or make fun of the patient in a rude manner. For those who have poor memory training, they can use the method of writing the names of objects and time to strengthen their memory, but they should be persistent.
