Alzheimer’s disease, also known as dementia, is mainly due to atrophy of the hippocampus and temporal lobe of the patient, resulting in cognitive decline. As the disease progresses and worsens, the patient can eventually become bedridden and die due to infection. For patients with Alzheimer’s disease, it is recommended to take oral brain-boosting foods and medications. Food can be taken orally, such as nuts and walnuts, while eating more fresh vegetables, which can supplement the body with vitamin C and prevent malnutrition. At the same time, for patients with Alzheimer’s disease, oral medications can be drugs to improve brain cell metabolism, such as Olacitant capsules, cytarabine sodium tablets, cerebroprotein hydrolysate tablets, etc. Patients can also be given oral cholinesterase inhibitors, which are commonly used clinically, such as rock cedrine A tablets and donepezil hydrochloride. For patients with Alzheimer’s disease, the diet should focus on protein to avoid malnutrition leading to infection in patients with advanced Alzheimer’s disease.
