Sudden loss of consciousness is a risk of stroke?

I am 40 years old, sometimes dizzy, dark, lose consciousness for 5-10 seconds, then normal. Am I at risk of stroke, what should I do? (Thanh Trung, Ho Chi Minh City)

Sudden dizziness and loss of consciousness for 5-10 seconds is a warning sign of a health problem that requires intervention. There are many different causes that can lead to this condition.

Loss of consciousness for 5-10 seconds (less than 5 minutes) may be a sign of a seizure or a mini-stroke, which occurs when blood is cut off from the brain for a few seconds, then the blood flow is restored and the person regains consciousness. However, this symptom may not be typical of a stroke. Migraine sufferers sometimes experience dizziness and sudden loss of consciousness.

Your case needs to be assessed more carefully in many aspects, for example, in what situation did it occur, how long did it last, what were the symptoms, what happened afterwards, and how often it recurred.

To know for sure the cause and level of danger and risk of stroke, you should go to a hospital with a neurology department so that the doctor can evaluate and screen for related problems.

People with additional risk factors such as underlying diseases, high blood pressure, cardiovascular disease, diabetes, obesity, smoking, high blood fat, family history of stroke... need screening to prevent the disease. Depending on the level of occurrence and impact of risk factors, the doctor will prescribe the appropriate stroke screening method.

You should choose a medical facility with a specialist or a reputable neurological center for a thorough and accurate examination. Modern equipment and machinery specialized in the field of neurology and stroke screening actively support diagnosis and treatment.
