Blood clots in the brain can cause strokes. There are four types of accidents. Two unrelated to blood clots and are caused by bleeding from a blood vessel or artery (subarachnoid hemorrhage or cerebral). The other two types of strokes are caused by blood clots. These are called thrombosis and cerebral embolism. An accident is precipitated by a thrombus (clot) formed in the arteries that stops or slows the flow of blood to the brain. The other is created when an embolism, a wandering clot elsewhere in the body, lodges in an artery and causes decreased blood flow. Since these accidents can cause permanent damage, it is important to know the symptoms of blood clots in the brain.
What are the signs and symptoms of a blood clot
Cerebral thrombosis (clot in the brain) is the most common cause of stroke. Often occurs when blood pressure is low. Often occurs at night or first thing in the morning, because blood pressure tends to be lower then.
Stroke versus clot
Clots symptoms are similar to the symptoms of a stroke. Often there are no symptoms until the time of the accident, or “brain attack.” One of the symptoms that may appear before a stroke is the headache that does not go away or is more severe than any you’ve had before.
Symptoms of blood clots in the brain include headaches and dizziness. These may be accompanied by changes in vision. There may be changes in speech or difficulty speaking. Paralysis of any part of the body can also be a sign of a clot or stroke. The trouble walking, even if not paralysis can be felt.
Transient ischemic attacks
Sometimes these symptoms are experienced for a very short time, possibly just a few minutes. This could mean what is called a transient ischemic attack (TIA). This is a “mini-stroke” that can lead to a full stroke. Therefore, even if the symptoms dissipate quickly, a person with these symptoms should get immediate medical attention.
Because blood clots block blood flow and may cause strokes when they are in the brain, are very dangerous. The problem is that the cells quickly die without blood to the brain, which is as permanent damage may occur. The sooner you try, the less chance of having long-term permanent disability due to the death of brain cells.
