10 Signs of Blood Clot in Brain

Blood clot in brain


The clotting of blood is essential in ensuring that excessive loss of blood is avoided. This happens with the help of a blood component known as platelets.

It normally takes place in order to protect the body against complications that may result from excessive blood loss. However, in some cases, a blood clot can abnormally develop in the blood vessels therefore, causing an interference in the flow of blood to some parts of the body.

When a blood vessel is blocked, essential factors like oxygen and nutrients needed for normal functioning of the recipient body organ will not be fully provided.

The shortage of oxygen and nutrients can further lead to complications of adverse severity.

For instance, the brain has a control of every activity carried out in the body. Its failure to function normally due to lack of oxygen can impair functioning of the whole body.

A blood clot can be formed in the arteries that directly supply blood to the brain. But in some cases, it is formed in other parts of the body but then suddenly dislodges and moves along with the blood towards the arteries of the brain, causing a blockage against flowing blood.

The blockage is a primary cause of stroke amongst most of the incidences.


The common signs and symptoms of blood clot in brain include the following

1. Recurring headaches

There are several causes of headaches in a person.

It is also known that some headaches can occur without any evident reason.

When headaches occur recurrently without being triggered by any known reason, it may be likely associated to be caused by a blood clot in the brain.

A blood clot in brain can result to increased pressure exerted within the arteries due to blood accumulation trying to pass through the blocked arteries.

2. Problem in speech

A blood clot can lead to insufficient oxygen in different parts of the brain.

The type of artery affected will define its specific influence on the brain. This is to say that impairment in functioning mainly depends on the part of the brain affected.

Since different parts of the brain carry out different tasks, the role played by the part involved will be affected.

In some cases, speech of the patient may become slurred or garbled. In this event, the speech coordinators in the brain would likely be the area affected.

3. Paralysis

Paralysis is a common symptom of stroke which is mainly caused by a clot in the brain of the patient.

In some cases, failure of the brain to receive enough oxygen may result in paralysis on some of the body parts.

Commonly, the arms, face and legs are the areas mostly affected. They will display a loss of normal sensory or motor function.

4. Depression

This can happen when a person is diagnosed with a blood clot, especially if the clot is life-threatening and extensive.

Depression is an emotional state which has shown to affect the outcome of medical treatment.

It is normal to feel anxious, shocked and fearful following the diagnosis of a blood clot.

5. Confusion

Thought processes and understanding are some of the main activities that are coordinated in the brain.

In situations where the brain is blocked from receiving enough oxygen, its normal activities will be compromised.

A patient undergoing this condition will behave as if they cannot understand any single word; or it takes too long for the person to reason and comprehend.

This can happen even when the patient is given with only simple instructions that could be easily understood.

6. Vision problems

A clot in the brain can result in the patient’s inability to see properly due to visual function being tampered.

The brain area involved with vision processes (occipital lobe) will become unable to be in a position to work normally due to lack of oxygen.

The individual may experience blurred vision or double vision.

In some cases, the patient may experience tunnel vision as well as complete inability to see.

Also, the patient can lose the ability of sight only in one eye and still be able to use the other eye.

7. Poor coordination

Body coordination of a person depends greatly on the functionality of the brain.

Impairment of the brain by any means can also affect the brain’s ability in coordinating normal body activities such as movement.

When cells of the brain lack the supply of oxygen, they can become sluggish or worse, if the cells do not receive any oxygen at all, they could die.

If the body parts involved in coordination are sluggish or denatured, there will also be a loss of balance or in extreme cases, there will be no visible coordination at all.

8. Ischemic attack

When only one side of the brain is deprived of enough oxygen, it may imply that one side of the body will experience the dysfunction.

At this stage, the condition is referred to as hemiplegia.

If this type of stroke is not managed, it may escalate, possibly leading to dysfunction of the whole body.

9. Increased heart rate

Since the brain also controls most of the metabolic activities in the body, any disorder in the functioning of the body will normally be dealt with to try and rectify the problem.

Shortage in the supply of oxygen to the brain will lead to an increased heartbeat given the aim of offsetting the imbalance.

The brain will command the heart muscles to increase the rate of their expansions and contractions in order to make sure that enough oxygen reaches the brain.

10. Rapture of blood veins

In extreme cases, the blood collected in the blocked vessels may lead to rupturing of the vessels itself. This is due to the pressure exerted on the walls of these vessels.

The rapture may lead to complications to the extent of causing death.

The brain is a major and very important part of the human body. Conditions that may render it incompetent in carrying out its functions should be given attention at any cost.

In case any of these signs are present, a medical examination should be sought for immediately in order to identify the true cause of the problem.


  • A blood clot in brain is a primary cause of stroke
  • The brain needs oxygen in order to perform its functions properly
  • Brain failure can result to the loss of function of other parts of the body
  • Coordination is one of the main functions of the brain that gets altered due to the presence of a blood clot in the brain
