Cerebral blood clots, also known as cerebral thrombosis or embolism, occur when a blood clot blocks a cerebral blood vessel, interrupting blood flow and potentially leading to a stroke or other serious complications. If left untreated, this condition can be fatal. Fortunately, the body may give advance warning through certain signs – not always obvious – that can appear up to several weeks before a stroke occurs. Here are 9 warning signs to be aware of:
1. Sudden intense headache
Cerebral blood clots can cause sudden, unusual headaches that appear without warning. This pain can last for hours despite the use of painkillers and is a serious sign that requires immediate medical attention.

2. Weakness or paralysis on one side of the body
You may experience sudden weakness or numbness in your arm, leg, or face, especially on one side of the body. This is a classic symptom of a stroke caused by a blood clot and can make daily activities and movement difficult.
3. Speech difficulties
Suddenly speaking with a lisp, slurring your speech, or having trouble understanding others could be related to a cerebral blood clot. You may find it challenging to express yourself or understand speech despite being awake and conscious.
4. Vision problems
You may experience blurred vision, double vision, or temporary loss of sight in one or both eyes. These symptoms typically occur suddenly and may be accompanied by other neurological signs, indicating interrupted blood flow to the brain.
5. Loss of balance or coordination
Feeling dizzy, unsteady, or like everything is spinning can be due to a blood clot. This is a dangerous sign as it increases the risk of injury and indicates an acute neurological issue.
6. Disorientation or cognitive impairment
You may suddenly feel confused, unable to comprehend simple sentences, follow conversations, or recognize familiar people. This indicates severe oxygen deprivation in the brain and requires immediate intervention.
7. Fainting
Severe blood clots in the brain can cause sudden loss of consciousness. This is a medical emergency requiring immediate attention to prevent irreversible brain damage.
8. Seizures
Some people experience their first seizure due to a blood clot. Seizures are sudden, uncontrolled electrical disturbances in the brain that result in loss of consciousness or unusual movements.
9. Nausea
Feeling nauseous or vomiting without an apparent cause, especially when accompanied by neurological symptoms, could be due to increased pressure or stimulation in the brain. Do not ignore this symptom.
If you or someone you know experiences any of these signs, seek medical help immediately. Cerebral blood clots are a medical emergency, and early intervention is crucial to prevent severe consequences.
