In the brain tumor disease, the incidence of epilepsy is about 30%, before surgery, patients with epilepsy, and half of the patients for the first time, some of the symptoms of a long period of time. The seizure location and nature of the tumor and have a certain relationship, such as sports area and near the tumor incidence of epilepsy is higher, the nature of the tumor in pathogenesis of meningiomas, astrocytoma and oligodendroglioma and higher rate. The causes of seizures are caused by direct stimulation or compression of the tumor. Due to the increased intracranial pressure caused by less, the type of attack is often limited to the type, can also be a major attack or tonic type (cerebellar type).

Large seizures refers to systemic muscle spasm, at the onset of loss of consciousness, generally the attack process is divided into 4 phases: (1): in the prodromal period before the onset of several hours or 1~2 days, patients showed lethargy, excitement, irritability, dizziness and prone to discomfort, and there will be had a seizure feeling. (2) the aura: epileptic discharge occurs symptoms appear in a short time, loss of consciousness and systemic circulation before the onset of the. There are many different types of aura, such as sensory aura, motor aura, visual aura, auditory aura, visceral aura, aura, complex aura, and so on. Aura duration is very short, usually for a few seconds, a few minutes up to a few minutes. (3): different spasm stage falls, sudden loss of consciousness, bilateral mydriasis, light reflex, muscle spasm, a straight dyspnea, cyanosis, incontinence. General clonic period lasts several minutes. (4) the spasm of the latter period: the whole body muscle spasm stops, the breath is gradually stable, the complexion returns to normal, about several minutes or half an hour or so from coma to awake, after waking up to the whole body convulsion attack has no memory. After the attack, often sleep a few hours, after the patient felt headache, dizziness, weakness, and sometimes mental disorders.

Epilepsy: more common in children, adults are generally divided into two types: (1) petit mal, transient loss of consciousness, most of the patients lasted for a few seconds, showing a sudden interruption of speech, do not move, I face pale, eyes gazing at the hands of the object floor, serious when can fall over, sometimes the urinary incontinence. The onset of a stop, the patient immediately awake, no knowledge of the attack. (2) myoclonic seizures, mostly in the head, neck, upper limbs and trunk extensor muscle twitch, and tic is rare, the general attack on both sides at the same time, all the time is very short, less than 1 minutes, a clear sense of attack patients.

Focal epilepsy (focal seizures: e) for cells of cerebral cortex in small scale attack by lesions produced by stimulation, the most common is the focal motor epilepsy. Such as by the limitations of the attack caused by systemic seizures, also known as Jackson epilepsy. Was located in the motor area, often see the mouth, finger and foot acupuncture, numbness or shock like feeling, also can be extended to adjacent areas, the emergence of a limb or on one side of the body feel abnormal, sometimes spread to neighboring motor areas produce localized muscle twitches. This is limited to the onset of the attack, the general is not accompanied by a sense of disorder, the patient can remember the attack. When partial discharges spread to the entire cerebral hemisphere, they become a major attack.

Psychomotor seizures: with mental symptoms, patients with olfactory, auditory hallucinations, hallucinations, fear, anger, pain or pleasure, sense of deja vu, as if in a dream like twilight. Also can appear some unconscious movements, such as noise, destroy, run, Shenshe, swallowing, fugue. Each episode lasted several minutes to ten minutes, sometimes up to several hours or even several days. Wake up after the attack, the attack can not remember.
