From your description, I think your mother is not only forgetful, but also likely to suffer from mild Alzheimer's disease, that is, Alzheimer's Harmo's disease. So first of all, I suggest you take your mother to the neurosurgery department of a big hospital as soon as possible, and the doctor should give you more advice. For example, sleepiness may be due to insufficient blood supply to the brain (lack of blood, lack of oxygen makes you want to sleep), so you can also check hyperlipidemia and thrombosis by the way.

At present, there is no specific medicine that can directly cure Alzheimer's disease. Scientists tend to treat Alzheimer's disease with nutrition. More effective are nutrients rich in DHA, such as deep-sea fish oil and algae, which can maintain the nutrition of brain cells and pay attention to these nutrients.

However, nutrition basically only plays a role in delaying the severity of Alzheimer's disease. The severity of Alzheimer's disease varies from person to person. Your mother's condition may gradually require special care. If the child has no energy, it is recommended to find someone to take care of him, or see if there is a better nursing home around him.

In addition, according to the truth, chronic nephritis is nephropathy, and Alzheimer's disease is encephalopathy. There is no direct connection between the two, but it illustrates a problem: your mother's overall health is not very good. Enhance immunity, moderate exercise (such as morning exercise, walking and Tai Ji Chuan) is more reliable than taking medicine!

I study neurophysiology, and what I said may not be right, but since I have written so much, I hope it will help your question!
