What diseases can cause insufficient blood supply to the brain? How to prevent insufficient blood supply to the brain?

The standard for measuring the blood supply to the brain is cerebral blood flow. Once the cerebral blood flow decreases, the oxygen and energy supply to brain cells will also decrease. All the oxygen needed by the brain is supplied by blood, so there must be enough blood supply for the brain to function normally. So, what diseases can cause insufficient blood supply to the brain? How to prevent insufficient blood supply to the brain? Let's learn more about it with Encyclopedia Knowledge Network!

What diseases can cause insufficient blood flow to the brain?

1. Metabolic syndrome

Factors such as high blood pressure, high blood lipids, and high blood sugar can increase the risk of arteriosclerosis, and can also increase blood viscosity, slow blood circulation, and cause insufficient blood supply to the brain.

2. Heart disease

For example, in patients with coronary heart disease, their cardiovascular stenosis causes a decrease in the amount of blood pumped by the heart each time, so the blood supply to the brain is also lower than normal, which in turn causes insufficient blood supply to the brain.

3. Low blood pressure

When the arterial blood pressure of an adult is lower than 90/60 mmHg, it is considered hypotension. If the blood pressure is too low, the amount of blood pumped by the heart will be reduced, and there will be no "power" to push the blood pressure forward, resulting in insufficient blood supply to the whole body including the brain, causing this disease.

4. Systemic diseases

Blood diseases, rheumatic and immune diseases, etc.

What should people with cerebral ischemia pay attention to?

1. Stay asleep

People with insufficient blood supply to the brain are prone to drowsiness due to lack of oxygen and ischemia in the brain. This situation can be treated according to the physical condition. You can take more rest, ensure adequate sleep, avoid staying up late, and avoid overwork for a long time.

2. Massage

Massage is a way to improve insufficient blood supply to the brain and speed up blood circulation in the brain. To massage the head, spread out five fingers and slowly massage from both sides of the ears to the top of the head, and then press to the back of the head. You can also massage the neck, which also helps speed up blood circulation in the brain.

3. Medication

The degree of ischemia caused by insufficient blood supply to the brain is different, so the choice of medication is also different. It is recommended that you go to the hospital regularly for relevant examinations to see the degree of ischemia, and then choose appropriate medication to control the progression of the disease.

4. Diet

People with insufficient blood supply to the brain must have a light diet and avoid eating spicy, irritating, greasy, sugary, or oily foods. They must restrain themselves from eating fatty meat and animal offal, etc. They should eat more fresh vegetables, fruits, and whole grains, and eat more kelp, black fungus, celery, and other foods that have the effect of clearing blood vessels.

5. Exercise

We should pay attention to outdoor exercise, especially regular exercise such as running, yoga, etc., which can help increase the elasticity of blood vessels, prevent vascular sclerosis, and improve the lack of blood supply to the brain. However, we should also pay attention to not exercising too vigorously, otherwise it will aggravate the ischemia.

How to prevent insufficient blood supply to the brain

1. Healthy people should get enough sleep, exercise regularly, and quit smoking and drinking.

2. Actively treat primary diseases, such as hypertension, hyperlipidemia, and hyperglycemia, and control corresponding indicators on a daily basis.

3. Keep a good mood and stick to proper physical exercise, such as jogging, walking, Tai Chi, etc. Exercise for 30 to 40 minutes every day, at least 4 to 5 days a week, and maintain a healthy weight.

4. Go to bed early and get up early, and try to reduce the time spent playing with your phone or looking at the computer. Avoid sitting for long periods of time, correct bad sitting postures, and move your neck regularly. People who look down at their phones should pay more attention to this, as cervical spondylosis is also one of the causes of insufficient blood supply to the brain.

5. In your free time, you can do some art or housework, or engage in some recreational activities, such as singing, dancing, calligraphy, painting, etc., to enhance brain thinking; you can also cooperate with some psychological treatment to relax your mood and reduce stress.

What tests are needed for cerebral insufficiency?

1. Laboratory examination

Testing of indicators including blood sugar, blood lipids, homocysteine, liver and kidney function is very necessary for finding the cause, determining the prognosis and preventing stroke.

2. Head CT

Head CT can show normal or small low-density ischemic lesions and softening lesions in the brain, and generally no new lesions. It can be used to exclude other organic diseases.

3. Head MRA

It is a non-invasive vascular imaging technology that can provide a preliminary understanding of brain vascular stenosis, occlusion, etc.

4. Cerebral CT angiography (CTA)

It can show whether there is stenosis in the intracranial or carotid arteries, the degree of stenosis, collateral circulation, etc.

5. Cerebral angiography

It can clearly show whether there is stenosis in intracranial blood vessels, the degree of stenosis, collateral circulation, etc., which helps to clarify the diagnosis and guide treatment.

6. Transcranial Doppler and carotid ultrasound

Transcranial Doppler can show reduced cerebral blood flow, occlusion or stenosis of cerebral perfusion arteries; carotid artery ultrasound can detect stenosis or occlusion of the carotid artery and vertebral-basilar artery, and determine the degree of stenosis; it can evaluate the compensation of collateral circulation and understand the status of cerebral blood circulation.
