Brain tumors produce seizures as their initial symptom, which affects approximately 80% of patients. This occurs because the brain’s normal electrical signals become disrupted, when abnormal brain cells appear. The brain experiences abnormal electrical activity which results in seizures that cause patients to experience twitching limbs, jerking movements, numbness, unusual sensations and loss of consciousness. People who have never had seizures, need to visit their doctor right away after their first seizure occurs. The presence of seizures indicates a brain function problem which requires immediate medical attention, because they represent a direct sign of abnormal brain activity.
