Alzheimer’s is not yet curable, so active prevention and rehabilitation are especially important and may somewhat slow down the progression of the disease and improve memory loss. Frequent recall: Ask the elderly frequently about things that just happened, such as who they just received a phone call from or what they just ate. Patients can also be trained to recall things they did a short time ago, such as what groceries they bought in the morning and where they put their wallet. Patients can also be helped to recall what they ate for dinner yesterday and where they have been recently, etc. It is recommended to use words or pictures or cards. Literacy cards for teaching small children are a good choice. Do more arithmetic: Have the elderly try to calculate the value of items, determine how many items are in large quantities, and use playing cards, etc. Get an abacus and a calculator to exercise arithmetic skills. Ask and answer: Encourage seniors to communicate and express themselves more often, which is the key to repairing their language skills. For example, when watching TV, feel free to say what you think to achieve the purpose of using your brain power. Label the room: When the environment is dark, the elderly’s ability to respond decreases, so you can make a clear difference in the layout of each room, put a striking animal pattern on the bathroom door, or put a teddy dog inside, and a teddy bear in the bedroom. At night, there are floor lights in the bathroom and bedroom, etc. As for the outside space, you can take the patient to identify more markers around the home and then bring cards for easy reminders. Sorting games: Families can fix logical thinking by doing some card, puzzle, and connection games to categorize items and identify shapes. For example, line up plastic models in order of 1, 3, 5, and 7 and ask the patient to fill in the spaces with even numbers.
