Dementia is clinically known as Alzheimer’s disease, and anyone can get it, but older people, people with a family history of the disease, people with mild cognitive impairment, people with chronic illnesses, and people with a history of head trauma are usually more susceptible to the disease than normal people. 1. Elderly people: The probability of developing Alzheimer’s disease increases with age, so older people are more likely to develop the disease than younger people. 2. People with a positive family history: Alzheimer’s disease runs in families, especially if the father or siblings have the disease, they are more likely to develop the disease than others. 3. People with mild cognitive impairment: When a person’s memory or other thinking skills decline more than expected for their age, they are also more likely to develop Alzheimer’s disease. 4. People with chronic diseases: People with chronic diseases such as high blood pressure, type 2 diabetes, and high cholesterol are also at higher risk of developing Alzheimer’s disease than normal people. 5. People with a history of head trauma: People who have suffered severe head trauma are also susceptible to Alzheimer’s disease. At present, although there is no specific drug to reverse Alzheimer’s disease, but active and effective treatment can slow down the development of the disease, it is recommended that patients seek timely medical treatment, active treatment to control the condition.
