Guide To The Symptoms Of Brain Cancer

Speech Difficulties

Brain tumors that form in the temporal and frontal lobe of an individual's cerebrum are most likely to produce problems with their speech and communication skills with others. The frontal lobe in an individual's brain has a high involvement in the production of language, as is the left hemisphere of the brain. Many patients who have a cancerous brain tumor in these areas of the brain experience stuttering or slurring of their speech. If the part of the brain responsible for the activation of certain muscles that create sound when an individual speaks is affected by the tumor, they will have trouble with their speech. A brain tumor can cause an obstruction in the impulses that flow through the nerves that connect the area of speech formation to the area that tells the muscles to express the speech. A malfunction in this connection causes the patient to experience problems with their speech. A tumor can affect the brain in the areas responsible for an individual's speech by the pressure it places on the structures and by the tissue swelling that occurs around it.

Double Or Blurred Vision

Brain cancer can produce double or blurred vision in several different ways. It can cause the overall pressure inside of a patient's skull to increase, which can cause their optic disc to become swollen. The optic disc is the part of the eye where the optic nerve enters the brain from the eye, and vision changes occur when the optic disc swells and compresses the optic nerve. Another way brain cancer can cause blurry or double vision is by the accumulation of cerebrospinal fluid in the brain that places too much pressure on the cranial nerves. One of the cranial nerves is the optic nerve, which can become impaired by excessive pressure from too much fluid. An individual who has blurry or double vision as a result of brain cancer most likely has a tumor in the occipital lobe, brain stem, or cerebellum.
