Introduction to Dementia

In particular, it will affect memory, attention, language, and problem solving ability. In severe cases, it is impossible to distinguish personnel, features and features. Dementia can be reversible or irreversible, depending on the disease. Less than 10% of dementias are reversible. Dementia is an unspecific general term. Also called dementia .

Dementia symptoms

The most common type of dementia is dementia in the elderly (aka Alzheimer's). Its typical initial symptom is memory impairment. Patients forget what just happened (poor short-term memory), while older memories (long-term memory) are relatively unaffected in the early stages of onset.

Dementia affects language ability, comprehension, motor ability, short-term memory, ability to recognize daily necessities, reaction time, personality, execution ability, problem solving ability. Even if there are no signs of mental decline, there are often delusions (15-56% of the Alzheimer type), such as suspecting that he is another person in the mirror.

Symptoms of dementia also include changes in personality or behavior. Many of the cases that were last diagnosed with dementia experienced severe confusion during the early stages of hospitalization. The elderly may also have symptoms of intellectual changes due to other medications, surgery, infections, insufficient sleep, abnormal diet, dehydration, change of residence or personal crisis. This is called delirium, and the symptoms are similar to mental illness or dementia.

Because most people with dementia may have symptoms of insanity. Although the symptoms of confusion may be alleviated by close care, improved living conditions, and diet; psychiatric drugs can also help stabilize mood, reduce hallucinations, or impulse control. But the drug has not yet slowed brain degradation. Dementia patients are often accompanied by depression, which is best diagnosed and treated by professional medical personnel.

Dementia epidemiology

Age is the most important risk factor for dementia. According to epidemiological studies, 5% of people over the age of 65 have dementia, and it increases to 20% of those over the age of 85.

Classification of dementia

Causes of degenerative dementia

Most dementias are degenerative. The following three categories are most common:

Alzheimer's disease: The most common cause of dementia.

Frontotemporal lobe degeneration

Dementia with Lewy Bodies

Causes of vascular dementia

Dementia caused by cerebrovascular disease.

Rare causes

Parkinson's Disease

HIV infection: AIDS dementia

Brain injury

Treatable causes

Less than 5% of the causes of dementia are treatable.

Vitamin B4, B12 and Vitamin A are missing.

Tumor

Dementia Treatment

In terms of dementia drugs, acetylcholine inhibitors are the mainstay. It is a kind of cognition-promoting drugs. The drugs currently on the market include Ai Yixin, Yi Sineng and Li Yiling.
