40% of people with transient ischemic stroke

A transient ischemic attack is considered an important warning sign of stroke. About 40% of people with transient ischemic events will experience a stroke, according to the American Stroke Association.

Associate Professor Dr. Nguyen Thi Hung, vice president of HCMC Neurology Association, said: ' Transient ischemic is considered to be a rapid recovery of cerebral vascular accident , recovery time from a few minutes to a few hours. , up to a day and leave no sign of weakness'.

Cerebral anemia is a condition in which blood flow to the brain is reduced so it does not provide enough oxygen and nutrients needed for certain areas of the brain. The cause is hardening of the blood vessels, narrowing of the vein or due to heart disease causing blood clots to move to the brain, causing a narrowing of the blood vessels. These congestion cases are very likely to occur because the cerebrovascular system is predominantly blood vessels, very small and vulnerable.

According to world medicine, chronic ischemia is common after age 55 but appears early in young people who have risk factors such as atherosclerosis, diabetes, dyslipidemia, live and working in a stressful, polluted environment . Depending on the level of anemia and the function of the brain cells that the blood vessel nourishes, the body will experience various symptoms such as limb weakness, mouth distortion, difficulty speaking, talking, half-numb, dizzy, dizzy, dizzy . In addition, there are some other symptoms such as reducing the ability to concentrate, the "problems" of memory until those Serious symptoms like cognitive disorders, memory loss like Alzheimer's .

When there are signs of transient ischemic attacks, patients should be placed

After more than a month after her transient anemia, Ms. Nguyen Thi Hong (34 years old, District 5, HCMC) is still afraid. She said: 'I was waiting for the green light at the intersection to be dizzy, limp, half-numb and fall off my motorbike. Taken into a hospital, the doctor diagnosed me with a transient ischemic attack. No sequelae, but I was scared because I heard that the risk of stroke afterwards was very high. '

After being admitted to the hospital after being distorted, unable to speak for nearly 6 hours, Mr. Le Quoc Trong (46 years old, Binh Chanh District, Ho Chi Minh City) was diagnosed as a transient ischemic. This is not the first time Mr. Trong has encountered these signs. He shared: 'There was a time when I was distorted in my mouth and pouted for a few minutes, thinking of hitting the wind, so I didn't go to the doctor. This time everyone rubbed the shaving oil for a while and still couldn't help but take it to the hospital. '

Transient ischemia is quite common, but not everyone is aware of the seriousness of this condition. Many people with transient ischemic heart disease, after one or two times, do not have serious consequences, they are prone to disregard, refrain from monitoring and screening risk factors. By the time of the actual accident, it was late.

In terms of pathogenesis, according to Associate Professor Hung, lesions often start from the vascular wall - where free radicals produce a lot in the continuous metabolism in the endothelium. With poor stability, free radicals rob the electrons from surrounding atoms, damaging the arterial cell structure, leading to the formation and development of atherosclerosis, blood clots that interfere with blood circulation. If the blockage is cleared immediately, the patient can recover after a few minutes, but if prolonged it will lead to a catastrophe.

In addition, a decrease in blood flow to the brain also causes damage to the structure or death of brain neurons, thereby increasing the risk of dementia with conditions such as memory loss, forgetfulness, Alzheimer's. . A study by scientists in the Netherlands showed that the group of elderly patients with dementia had much lower blood flow to the brain than the same age group with normal brain function and younger age group. .

In theory, after only 4 or 5 minutes of receiving no oxygen and nutrients, the damaged brain cells could not recover. In cerebral anemia and seizures, when a blood vessel is blocked, the surrounding blood vessels may be 'hospitalized' but the time to endure is not too long. Therefore, the treatment, examination and treatment of blood clots only bring the best results in the first 3-4 hours.

When encountering signs such as dizziness associated with one-sided weakness, sensory disorders, facial distortion, difficulty speaking . need to think immediately of transient ischemic attacks, even cerebral infarction. The most urgent need is to immediately bring the patient to a medical facility with enough equipment for examination and testing to determine the diagnosis of a stroke, risk factors and treatment measures. fit.

Professor Hung advises: 'To reduce the risk of cerebral anemia and other cerebrovascular diseases, each person should have a disease prevention strategy for themselves soon . " Accordingly, it is necessary to maintain a diet and exercise. Scientific, working and resting properly to avoid stress Control of risk factors such as good treatment of hypertension, diabetes, dyslipidemia, arrhythmia . Besides, should increase Enhance anti-free radicals in your diet or use other supplements to prevent vascular wall damage.

Anthocyanin biologically active substances, Pterostilbene (included in OTIV) are extracted
Blueberry helps prevent free radicals, protects nerve cells and cerebral vessels.

In recent years, modern medicine pays attention to the use of Blueberry - a fruit of North American origin - to fight free radicals, protect blood vessel walls and brain nerve cells. The group of biological active ingredients against free radicals in Blueberry such as anthocyanin, pterostilbene increases the synthesis of enzymes necessary to neutralize free radicals that damage blood vessels, while helping to limit the process of forming atherosclerosis and thrombosis, reducing the risk of cerebral anemia.

Blueberry also helps protect brain nerve cells from the attack of free radicals, effectively supporting brain activities and reducing the risk of neurodegeneration.
