A blood clot in the brain can cause a range of serious symptoms. Among them are severe headaches, coordination problems, visual disturbances, and language difficulties. Blood-clot related language difficulties may include not only those that are evident when a person speaks, but also those that cause problems processing the speech of others. Paralysis is also among the symptoms of a blood clot in the brain. Weakness and numbness in various parts of the body may also develop as the result of a blood clot.

When a person has a blood clot in the brain, it may develop within the brain or move from another part of the body to the brain. Either way, a blood clot can cause many serious symptoms. For example, one of the common symptoms of a blood clot in the brain is a headache. In such a case, the pain of the headache usually starts suddenly and becomes intense. In many cases, people with these types of blood clots also experience stomach upset along with the headache.

Visual problems are also among the symptoms that may develop when a person has a blood clot in the brain. In such a case, a person may develop blindness in one of his eyes. Sometimes this is temporary, but it can also become a permanent problem. An individual may also experience other visual symptoms of a blood clot in the brain, including impaired and double vision. A person may lose the ability to see things in certain areas of his visual range as well.

Changes in coordination are also among the symptoms of a blood clot in the brain. A person with this condition may have trouble balancing or walking. He may also have problems with sudden falls as a result of the blood clot.

Often, a person with a blood clot in the brain will develop language-related problems. An individual with this condition may have problems forming words or forming words in a way that is easily understandable by others. Likewise, he may have trouble processing the words others say to him.

Body paralysis can also result from a blood clot. Often, the paralysis affects one side of the patient's body rather than both sides at one time. If a person does not experience paralysis, he may instead develop weakness in various parts of the body. In some cases, various body parts or one whole side of the body may feel numb as well.
