Beware Of Transient Ischemic Attacks
Transient ischemic attacks occur suddenly but do not last long, the disease recovers itself, but can recur. This is a symptom of cerebrovascular disease, signaling a stroke. Therefore, transient ischemic attack is considered an emergency and needs to be detected and treated promptly.
The brain is very sensitive to lack of oxygen. With only 4 minutes of lack of oxygen the nerve cells were destroyed irreversibly
If the blood vessels of the brain are narrowed or blocked, the flow of blood to the relevant part of the brain is disrupted. For example, when the area of the brain in charge of movement is damaged, the patient is paralyzed from the hemiplegia
If the perfusion only decreases for a short time, and does not kill the nerve cells, the symptoms are transient.
If a blood vessel is completely blocked, the nerve cells will die and the damage will be permanent, then called a stroke.
Risk factors for disease
It is thought that the main cause of transient ischemic attacks is caused by a blood clot from the heart or a plaque from a large artery that is pumped into a small blood vessel in the brain.
Therefore, the flow of blood in the arteries is reduced due to narrowed arteries, constriction or blockage, leading to sudden and short-term neurological disorders.
Factors that are prone to transient ischemic attacks or stroke include: genetics, patients often have relatives with cardiovascular disease before age 55; Patient age is often over 60 years;
Gender: men have more episodes of ischemic stroke or stroke than women; due to race; due to hypertension; cardiovascular diseases such as valvular heart disease, heart failure, atrial fibrillation ...; due to smoking; glycorrhea patient; high blood cholesterol; fat; drug addiction, heavy drinking, beer
Signs to detect brain ischemia
One study showed that about 7% of patients suffering from an ischemic attack suffered a stroke within 1 week, of which 50% of these patients had a stroke in the first 2 days and over 14% of those with another patient had a stroke within 3 months.
Suddenly living with the patient, the patient suddenly showed signs of unconsciousness, headache, mild weakness or hemiplegia; lisp or speechless; not seen in one or both eyes; loss of balance, unsteadiness, unsteadiness ...
It happened suddenly, but only lasted a minute or two to 10 minutes. If symptoms persist for more than an hour, often with severe damage, there may be a damaged brain area called a stroke.
During an examination during the first minutes of anemia, a patient with hypertension, cognitive disorders such as disorientation, drowsiness or unconsciousness, facial and hemiplegia, can lisp or not speak, or cannot speak, cannot understand
Cardiovascular examination may show cardiac arrhythmias, signs of stenosis of the arteries, most often the neck artery.
X-rays, scans do not detect signs of bleeding or damage of the brain. Blood tests can show high blood sugar or high cholesterol.
The disease should be distinguished from other diseases such as fainting, epilepsy, hypoglycemia, dizziness, inflammation or vestibular disorders, migraine with warning signs ...
The course of a common ischemic attack is a patient who fully recovered within minutes or within an hour.
However, the patient may have a relapse many times and may have a true stroke, with symptoms of coma and prolonged paralysis, irreversible, death.
Management attitude and prevent disease
Anemia is considered an emergency.
If anemia occurs, an ambulance or physician should be called at home, and patients should not drive themselves to the emergency room because of a dangerous accident.
Patients should be examined and tested to rule out the possibility of a stroke, if right, emergency treatment is required. If transient ischemic attack has occurred within 2 days, it is necessary to take the patient to an early examination at the hospital.
Preventing diseases is mainly reducing factors such as quitting smoking, treating hypertension, diabetes, raising cholesterol, cardiovascular disease, arrhythmia, anti-coagulation ...
Reduce the risk of atherosclerosis and stenosis by taking low-dose aspirin, plavix, aggrenox or anticoagulants. Patients with cerebral ischemia due to cervical artery stenosis may need surgery or angioplasty.
