Alzheimer’s disease is a progressive neurodegenerative disease characterized by memory loss, cognitive impairment, and impairment in everyday behavior, which has a significant negative impact on the patient’s daily life and severely reduces the quality of life. It is believed that the following groups of people are more likely to develop Alzheimer’s disease: (1) Uncontrollable factors: age (the risk of developing Alzheimer’s disease increases with age), higher prevalence in women than in men (probably related to the decline of estrogen with age), and genetic factors (people with family members who have Alzheimer’s disease are at increased risk of developing the disease). (2) Controllable factors: ① Diabetes, the risk of dementia and mild cognitive impairment is higher in older people with diabetes than in those without diabetes, so people with diabetes must control their blood sugar well. ② Hypertension, controlling blood pressure can reduce the risk of dementia. Hyperlipidemia, hypercholesterolemia can increase the risk of Alzheimer’s disease by inducing atherosclerosis and directly inducing neurodegeneration. Obesity, obesity increases the risk of all types of dementia, so weight loss is important. ⑤ Bad lifestyle: smoking, alcohol consumption, lack of exercise, improper diet structure, and poor socialization may increase the risk of dementia, so older people must quit smoking, limit alcohol consumption, exercise properly, get out of the house more often, and maintain a good social life. Therefore, senior women, people with diabetes, hypertension, hyperlipidemia, obesity, and poor lifestyle are more likely to suffer from Alzheimer’s disease.
