Guide To The Symptoms Of Brain Cancer

Seizures

A seizure is a medical event where a patient's brain experiences a sudden and uncontrollable electrical perturbation. During a seizure, an affected individual experiences alterations in their level of consciousness, movements, feelings, and behavior. The majority of seizures have a duration of around two minutes or less. Several different types of seizures may occur due to brain cancer, including grand mal, myoclonic, sensory, and complex partial seizures. A seizure can be caused by any mechanism in a patient that causes the interruption of normal nerve cell connections in their brain. This abnormal electrical activity that occurs in the brain of a patient is somewhat similar to an electrical storm. Seizures are more common in individuals who have a cancerous tumor growing in their meninges or cerebral lobes. The effects of an individual's seizure depend on the part of the brain the tumor is affecting. Everyone who has a seizure precipitated from a brain tumor will have a different experience.

Weakness

Weakness describes when an individual is unable to produce a muscle movement with their greatest effort to do so. It is not the same as fatigue, as their causes differ despite somewhat similar results. Weakness occurs when the nerve impulse from the brain and spinal cord does not reach the muscles in the affected limb or region of the body. The muscles do not contract without an indication from the brain to do so. Therefore, less effective or partial impulses make it to the muscles in the affected area and produce a minimal movement with great exertion of effort.

Malignant brain tumors that form in the cerebellum and or frontal lobe of an individual's brain can cause problems with the communication of nerves in the affected region. The nerves may become compressed or damaged from the effects of the tumor, causing them to be unable to relay the signal down the spinal cord and to the intended muscle to produce movement. Weakness that occurs on one side of an individual's body is more characteristic in brain cancer than weakness in both sides of the body.
