Alzheimer’s disease, also known as senile dementia, is a degenerative disease of the nervous system that develops over the age of 60. Its main manifestations are memory loss, calculation loss, judgment loss, language dysfunction, and some psychiatric symptoms, such as personality changes, hallucinations, delusions, suspicion, temper tantrums, and a decline in the ability to perform daily living, and in severe cases, patients cannot take care of themselves. So far, the cause of Alzheimer’s disease is still not very clear, generally related to genetics, age and vascular risk factors, as follows: first, genetics; second, age: the older you are, the more likely you are to develop Alzheimer’s disease. Third, vascular risk factors: some vascular risk factors, such as hypertension, hyperlipidemia, diabetes, heart disease, these will also increase the probability of developing Alzheimer’s disease. If you have Alzheimer’s disease, you must have early standardized treatment to slow down the progress of the disease.
