Multi-infarct dementia

Introduction to multiple infarct dementia This disease affects the blood supply to the brain due to cerebral arteriosclerosis, especially the dementia syndrome caused by recurrent cerebrovascular accidents. Microemboli or cerebral white matter in the cerebral white matter of the external cerebral artery (carotid or cone-like basilar artery) is caused by scattered small infarcts in the cerebral white matter center, and is therefore called multiple infarct dementia. The disease is mostly in the middle and old age, and the male is slightly more than the female. The course of the disease is mostly stepwise, often accompanied by localized signs of the nervous system. The root cause of this disease is caused by cerebral arteriosclerosis caused by organic changes in brain tissue. The degree of cerebral arteriosclerosis can vary from site to site. Those with hypertension and arteriosclerosis should be treated according to the internal medicine. An acute ischemic attack can be injected with injections such as salvia miltiorrhiza and Chuanxiong. Subjects with indications can be treated surgically. In order to improve cognitive function, you can take brain rehabilitation, brain rejuvenation and ribonucleic acid. Hyperbaric oxygen therapy and ultraviolet light oxygenation and blood return therapy can achieve certain effects in some early patients. When the psychiatric symptoms are more obvious, a small amount of antipsychotic drugs such as methotrexate can be used in combination, and once the symptoms are controlled, the drug can be stopped. basic knowledge The proportion of sickness: 0.01% Susceptible people: no specific people Mode of infection: non-infectious Complications: hemiplegia, renal failure

Causes of multiple infarct dementia

Causes:

The root cause of this disease is caused by cerebral arteriosclerosis caused by organic changes in brain tissue. The degree of cerebral arteriosclerosis may vary from site to site.

Multiple infarction dementia prevention

1, the blood pressure is controlled at a reasonable level because the blood pressure is too high, so that the microcirculation of the brain and the atherosclerotic small artery rupture and hemorrhage; and the blood pressure is too low, the blood supply is incomplete, and the cerebral infarction is easily formed when the microcirculation is stagnant.

2, life should be regular, work on time, work and rest, to ensure adequate sleep, do not drink strong tea or coffee and other exciting drinks before going to bed, can not be too excited, easily chat and chat, wash your feet with warm water, calmly fall asleep Moderate activities in the morning, the content of life should be rich, not to do nothing, lonely and bored, not too tired, lack of rest.

3, proper diet, not only to ensure adequate nutrition, but also to limit some foods that are unfavorable to the elderly, especially those with high blood pressure and high blood lipids, eat less animal fat peas oil, vegetable oil instead of lard, to rich Cholesterol-containing foods such as animal viscera, egg yolk, fish roe, squid, etc. should be restricted. Food should be mainly light and light, and sputum and salt should not be too much. It should also have necessary vitamins and other nutrients, and eat more vegetables. Bean mouth, lean meat and fruit.

4, weight control, obesity is one of the high risk factors of stroke.

Multiple infarction dementia complications Complications, hemiplegia, renal failure

1. There are different neurological signs, such as hemiplegia, depending on the location of the vascular infarction.

2. The course of the disease can last for several years or even more than 10 years. The cause of death is heart and kidney failure is more.

Symptoms of multiple infarct dementia Common symptoms Dizziness Bridge Cerebral infarction Ataxia Guess Fatigue Illusion Dementia Hypertension Anxiety

Most patients have a history of hypertension and hyperlipidemia, and some may have cerebrovascular accidents. Early patients complain of headache, dizziness, insomnia or lethargy, are prone to fatigue, reduce mental concentration, and the patient's original personality characteristics become More prominent, prone to irritability or nervousness, gradually appearing near memory impairment, long-term memory is relatively intact, intelligent damage sometimes only involves certain specific, limited cognitive functions, such as calculation, naming, etc., and general reasoning, Judgment can remain intact for a considerable period of time, often can detect these obstacles and actively seek medical treatment or make efforts to make up for it. Therefore, it is called "net-like dementia", the patient's mood is unstable, and the irritability is increased. Insignificant inducement leads to crying or laughing, called emotional incontinence, occasionally depression, anxiety, suspicion and delusion, loss of self-control in the late stage, self-care for personal life, and sometimes difficult to distinguish from Alzheimer's disease.

Examination of multiple infarct dementia

1. EEG is often abnormal;

2. Cerebrospinal fluid examination may have a slight increase in protein;

3. The cerebral blood flow is the same as the examination, the blood vessel elasticity is reduced, the resistance is increased, and the blood flow is reduced and slow;

4. CT scan shows low density areas and localized ventricular enlargement;

5. Magnetic resonance imaging can show ventricular infarction.

Diagnosis and diagnosis of multiple infarction dementia

It is distinguished from gliomas, metastases and brain abscesses, and other symptoms such as dementia. It is not difficult to identify by EEG and MRI.
