What Are The Signs And Symptoms Of A Blood Clot In The Brain?

Blood clots in the brain can cause strokes. There are four types of accidents. Two are not related to the formation of clots and are caused by bleeding from a blood vessel or artery (subarachnoid or cerebral hemorrhage). The other two types of strokes are caused by blood clots. These are called cerebral thrombosis and cerebral embolism. An accident is precipitated by a thrombus (clot) formed in the arteries that stops or slows blood flow to the brain. The other is created when an embolism, which is a wandering clot from another part of the body, lodges in an artery and causes a decrease in blood flow. Since these accidents can cause permanent damage, it is important to know the symptoms of blood clots in the brain.


Cerebral thrombosis (brain clot) is the most common cause of strokes. It often occurs when blood pressure is low. Many times it happens at night or first thing in the morning, since the blood pressure is usually lower then.

Clot versus stroke

The symptoms of clots are similar to the symptoms of stroke. Often there are no symptoms until the time of the accident, or "stroke." One of the symptoms that can appear before a stroke is a headache that does not go away or is more serious than any you had before.

Other symptoms

Symptoms of blood clots in the brain include headaches and dizziness. These could be accompanied by changes in vision. There may be changes in speech or even difficulty speaking. Paralysis of some part of the body can also be a sign of a clot or stroke. The difficulty to walk, even if it is not paralysis can be noticed.

Transient ischemic attacks

Sometimes these symptoms are experienced for a very short time, possibly only a few minutes. This could mean what is called a transient ischemic attack (TIA). It is a "mini-stroke", which can lead to a complete stroke. Therefore, even if the symptoms dissipate rapidly, a person with these symptoms should receive immediate medical attention.


Since blood clots block blood flow and can cause strokes when they are in the brain, they are very dangerous. The problem is that cells die quickly without blood to the brain, which is how permanent damage can occur. The earlier it is treated, the less long-term chances of permanent disability due to the death of brain cells.
