Introduction: As we age, many elderly people often feel dizziness, headache, confusion, nausea and other symptoms, although these symptoms are considered normal aging phenomena in the eyes of many people, but in fact, they may also be a distress signal sent by the body to you, indicating the occurrence of insufficient blood supply to the brain.
Cerebral insufficiency is a common cerebrovascular disease, which can lead to hypoxia and ischemia in the brain, which in turn causes a series of symptoms, and may even develop into serious diseases if not timely.
Therefore, the elderly should always pay attention to their physical condition, especially the recurrent uncomfortable symptoms, and once the abnormality is found, they should be examined and ** as soon as possible. 
Cerebral insufficiency refers to the slowing of blood flow to the brain due to various reasons, resulting in cerebral ischemia and hypoxia, which affects the normal function of the brain, and this phenomenon usually occurs in people who are elderly, frail, or have chronic diseases for a long time.
There are many causes of insufficient blood supply to the brain, the most common of which is atherosclerosis, which leads to narrowing or blockage of blood vessels, in addition, chronic diseases such as hypertension, hyperlipidemia, diabetes can also affect blood flow to the brain, resulting in insufficient blood supply to the brain.
Keep your head down or hold the same position for long periods of time
Looking down at your phone, computer or work for a long time can easily cause the cervical spine to compress the blood vessels, affect blood circulation, and then affect the blood in the brain**.
Excessive fatigue
Long-term high-intensity work or study, as well as a lack of adequate rest, can lead to physical fatigue, affect blood circulation and the function of the respiratory system, and thus affect the blood flow to the brain**.
Long-term smoking or alcohol consumption
Both smoking and drinking alcohol can cause damage to blood vessels, affecting blood circulation, which in turn affects blood flow to the brain**.
Unhealthy eating habits
Long-term intake of foods high in fat, sugar, and salt can lead to chronic diseases such as obesity, high blood pressure, and high blood sugar, which in turn affect the blood in the brain**.
Lack of exercise
Long-term lack of exercise can easily lead to slow metabolism and poor blood circulation, which affects the blood in the brain**.
Cerebral insufficiency does have the potential to lead to cerebral infarction.
When the blood supply to the brain is insufficient, brain cells are damaged due to lack of oxygen, and if this happens for a long time, brain cells may die, causing cerebral infarction.
Cerebral infarction is avascular necrosis or softening of localized brain tissue caused by blood disorders, ischemia and hypoxia in the brain.
"Facial paralysis" appears
Insufficient blood supply to the brain is a common neurological problem that affects the normal functioning of the brain by preventing the brain from getting enough blood**. Facial paralysis is one of the common symptoms of cerebral insufficiency, when cerebral insufficiency occurs, the control of facial muscles will be affected, resulting in facial muscle weakness or paralysis, and symptoms such as drooping corners of the mouth and incomplete eyelid closure appear.
In addition to facial paralysis, insufficient blood supply to the brain can also lead to other symptoms such as headache, dizziness, nausea, vomiting, blurred vision, etc., which may appear suddenly and last for minutes or hours.
Poor mental state
Insufficient blood supply to the brain can lead to a series of uncomfortable symptoms in the body, the most common of which is poor mental state, and patients may experience symptoms such as drowsiness, dizziness, difficulty concentrating, memory loss, etc.
In severe cases, confusion, coma, etc., these symptoms will not only affect the patient's quality of life, but also have a negative impact on the patient's mental health.
When these symptoms occur, it is necessary to be alert to the presence of cerebral insufficiency, and in order to relieve the symptoms of cerebral insufficiency, patients need to take a series of measures.
It's vague to see things
When the blood supply to the brain is insufficient, the body sends out some warning signs to remind us to pay attention to our physical health, among which blurred vision is one of the most obvious symptoms.
The brain, as the organ that controls vision, has an impact on the transmission of visual signals when the blood supply is insufficient, causing the vision to become blurry, as if shrouded in a layer of mist.
In addition to blurred vision, insufficient blood supply to the brain may cause other symptoms, such as headaches, dizziness, nausea, vomiting, and other discomforts, which may be caused by a lack of oxygen to the brain.
Unsteady walking
In life, if you find that you often have problems such as unexplained falls, unsteady walking, or movement disorders during a certain period of time, then it is likely that the cerebral blood supply is insufficient.
Insufficient blood supply to the brain can lead to a lack of oxygen and nutrients** to the brain, which can affect the function of the brain, and in this case, motor function will also be greatly affected.
Even if you are a very athletic person, when the brain loses enough oxygen and blood support, the motor nerves can become insensitive or even malfunction.
Frequent yawning, drowsiness
Frequent yawning is a very obvious symptom of insufficient blood supply to the brain, when the brain is deprived of oxygen, it will send a signal for the body to inhale more oxygen by yawning, which can help the body relieve the lack of oxygen, but it can also make people feel very tired and sleepy.
In addition to frequent yawning, drowsiness is also a common symptom of insufficient blood supply to the brain, and due to the lack of oxygen to the brain, people can feel unusually sleepy and tired, and even need to rest or sleep for long periods of time during the day.
This will not only affect people's work and life, but may also have a long-term impact on physical health, and should be taken seriously when symptoms of frequent yawning and drowsiness appear.
1. Neuroimaging examinations, such as MRI or CT, are required to check whether there are abnormalities in the brain, which can detect whether there are abnormalities such as infarction, bleeding or tumor in the brain.
2. Cerebrovascular examinations are required to check whether there are abnormalities such as stenosis, blockage or arteriosclerosis in the blood vessels of the brain, which can be performed by digital subtraction angiography (DSA), magnetic resonance angiography (MRA) or CT angiography (CTA).
3. Blood tests are also required to check whether there are metabolic abnormalities such as hyperlipidemia, hyperglycemia, and high uric acid, which may affect the cerebral blood supply.
Maintain a good diet
Patients with cerebral insufficiency should maintain a balanced diet and eat more foods rich in protein, vitamins and minerals, such as lean meat, eggs, vegetables, fruits, etc. At the same time, you should eat less foods that are high in fat, sugar, and salt, and avoid excessive alcohol consumption and smoking.
Exercise appropriately
Appropriate exercise can promote blood circulation, increase blood supply to the brain, improve physical function, patients with insufficient cerebral blood supply can choose walking, jogging, yoga and other low-intensity exercises, avoid strenuous exercise.
Control of underlying conditions
Underlying diseases such as hypertension, diabetes, and hyperlipidemia are one of the main causes of cerebral insufficiency, so patients with cerebral insufficiency should actively control these underlying diseases, take medications on time, have regular examinations, and keep blood pressure, blood sugar, blood lipids and other indicators within the normal range.
Maintain a good mindset
Factors such as mood swings and mental stress may also lead to the aggravation of cerebral insufficiency, so patients with cerebral insufficiency should maintain a good attitude, avoid the influence of excessive anxiety, depression and other bad emotions, and seek help from a psychologist when encountering problems.
Finger comb hair
Gently combing your hair from front to back with your fingertips can stimulate blood circulation in the scalp and increase blood in the head**, this action can be done about 50 times at a time, once a day in the morning and once in the evening.
Perform a neck rotation
The neck is an important channel of blood in the brain, and the rotation of the neck can promote the blood circulation of the neck and improve the blood supply to the brain, which can be done about 10 times each time, once a day in the morning and once in the evening.
