It is a syndrome in which you cannot even perform. Dementia is largely classified into Alzheimer's dementia, vascular dementia, and other dementia. Alzheimer's dementia is 71.3%, which is the most common type of dementia, and it is said that brain cells that were performing normal functions die without a specific cause and lose cognitive ability. It develops and progresses gradually and gradually, and the risk increases with age and is more common among women. Vascular dementia is 16.9%, and if patients with risk factors for stroke such as high blood pressure, diabetes, arteriosclerosis, heart disease, and hyperlipidemia do not receive appropriate treatment, cerebrovascular disease (stroke) or cerebrovascular dementia is likely to occur. . It is more common in the East than in the West, and more dementia in men in Korea. Other dementia accounts for 11.8%, and degenerative brain diseases lead to dementia symptoms as a result of the brain being damaged by shock or by brain tumors, central nervous system syphilis, carbon monoxide, alcoholism, and other diseases.

Looking at the diagnosis status of dementia, in the dementia test that asks a specific question to a test subject currently being conducted in public health centers nationwide, it is very difficult to test for dementia through a question as the test subject has a rejection to the question. There was a problem in that the most basic information about is not obtained.
