Early symptoms of cerebral vascular obstruction

Blockage of cerebral blood vessels, also known as cerebral thrombosis, is one of the most important causes of cerebral infarction. It mainly refers to atherosclerotic changes in the main cerebral arteries or cortical branch arteries, which often cause blood vessel thickening and narrowing of the lumen. At this time, blood clots will form. When patients have cerebral thrombosis, they often suddenly drool, speak incoherently, and have severe headaches. When these symptoms occur, you must go to the hospital for treatment in time.

Early symptoms of cerebral vascular obstruction

1. Drooling

Sudden slurred speech or drooling.

For elderly people who already have risk factors for cerebral thrombosis such as hypertension and diabetes, frequent drooling may be a precursor to cerebral thrombosis.

2. Sudden dizziness

Dizziness is a very common symptom of cerebral thrombosis and can occur at any time, especially when getting up in the early morning. In addition, it is also prone to occur when you are tired or after taking a bath.

Especially for patients with hypertension, if dizziness occurs more than 5 times in 1 to 2 days, the risk of cerebral hemorrhage or cerebral infarction will increase.

3. Sudden severe headache

Sudden onset of severe headache accompanied by convulsions, recent history of head trauma accompanied by coma and drowsiness, sudden changes in the nature, location, and distribution of the headache, headache aggravated by forceful coughing, severe headache and waking up in pain at night are prone to cerebral thrombosis.

4. Yawning

80% of patients with ischemic cerebral thrombosis will experience frequent yawning 5 to 10 days before the onset of the disease.

5. Blurred vision

It manifests as transient visual impairment or visual field loss, which usually recovers on its own within 1 hour.

6. Abnormal gait

Staggering and weakness in walking are one of the precursor symptoms of hemiplegia. If an elderly person's gait suddenly changes and is accompanied by numbness and weakness in the limbs, it may be a precursor to cerebrovascular disease, such as cerebral thrombosis.

7. Razor Drops

It means that when he was shaving with a razor, his head turned to one side and he suddenly felt his arm become weak, causing the razor to fall to the ground. He fully recovered after 1 to 2 minutes.

This is because when you turn your head and twist your neck, the already hardened carotid artery twists and aggravates its stenosis, leading to insufficient blood supply to the brain.

8. Abnormal blood pressure

When blood pressure suddenly rises to above 200/120 mmHg, it is a precursor to cerebral thrombosis; when blood pressure suddenly drops below 80/50 mmHg, it is a precursor to cerebral thrombosis.
