abdominal epilepsy syndrome
Introduction
Introduction to abdominal epilepsy syndrome Abdominal Apoplexy Syndrome is an epilepsy characterized by paroxysmal abdominal pain. In 1944, Moore reported this disease first, so it is also called Moore syndrome. In addition, it is also called visceral epilepsy and diencephalon. Epilepsy, thalamic and hypothalamic epilepsy, autonomic epilepsy, epilepsy variant, sputum equivalent, epilepsy etiology, non-sexual epilepsy equivalent syndrome, abdominal reflex epilepsy, helminthic epilepsy, autonomic reflex Epilepsy, island back epilepsy and so on. basic knowledge The proportion of illness: 0.005% Susceptible people: more common in children Mode of infection: non-infectious Complications: tuberous sclerosis edema
Cause
Causes of abdominal epilepsy syndrome
Cause (30%):
The cause is not yet clear. Some people think that it may be caused by head trauma, tuberous sclerosis, tumor and neurovascular edema caused by injection of diphtheria antitoxin. Some people think that some patients suffer from hypoxia, premature birth and serious infection. Related to factors such as diseases (such as encephalitis), Moore believes that this type of paroxysmal hyperactivity is associated with abnormal cortical discharge in the frontal lobe (6-zone), parietal lobe (5, 3), and is associated with the diencephalon.
Prevention
Abdominal epilepsy syndrome prevention
1. For epilepsy caused by hereditary diseases, it is necessary to conduct prenatal diagnosis and find that a fetus with epilepsy can be artificially aborted, which can reduce the occurrence of such epilepsy.
2. Patients with epilepsy should avoid marriage with family history of epilepsy when choosing a mating object. The fiancé (wife) of the epilepsy patient should have an EEG topographic map before marriage. For example, if the EEG topographic map has epilepsy, avoid marriage. People with a family history of epilepsy should also avoid getting married.
3, in order to prevent epilepsy caused by brain damage at birth, for the primipara, if the production process is not smooth, the laparotomy should be taken early, so as to avoid the occurrence of epilepsy in the future due to hypoxia, asphyxia and birth injury.
4, prevention of epilepsy caused by traumatic brain injury, the focus is to prevent the occurrence of brain trauma, to avoid brain trauma caused by work, traffic accidents.
5, about 15% of patients with febrile seizures will change into epilepsy. For example, if there is a possibility of recurrent febrile seizures, preventive measures should be taken early, which can greatly reduce brain damage caused by febrile seizures and reduce the incidence of epilepsy.
Complication
Complications of abdominal epilepsy syndrome Complications tuberous sclerosis edema
1, head trauma: due to sudden abnormal discharge of brain neurons in patients with epilepsy, resulting in transient brain dysfunction, easily lead to trauma.
2, tonic episode: manifested as a sudden sustained contraction of the paroxysmal whole body or bilateral muscles, muscle stiffness, so that the limbs and body are fixed in a certain tension posture, such as axial body extension dorsiflexion or flexion. It usually lasts from a few seconds to tens of seconds, but generally does not exceed 1 minute. Tonic attacks are more common in patients with epilepsy with diffuse organic brain damage, which is generally a sign of serious illness.
3, tumor and injection of diphtheria antitoxin caused by neurovascular edema, severe infectious diseases.
Symptom
Abdominal epilepsy syndrome symptoms Common symptoms Abdominal wall involuntary axis drowsiness, abdominal pain, nausea, dizziness, green appetite, loss of consciousness, convulsions, gastrointestinal symptoms
The disease is more common in children, and its onset time can often be traced back to infancy. Adults are rare. There was no significant difference in the incidence of men and women. It is characterized by sudden onset abdominal pain. The site is mostly around the umbilicus and the upper abdomen. A few can be radiated to the lower abdomen and ventral side. The pain is more severe, such as colic or knife cutting. It lasts for a few minutes and can last for more than a few hours. . Attacks are often accompanied by a certain degree of disturbance of consciousness, such as disorientation, perceptual or mental confusion, but no complete loss of consciousness. Often accompanied by loss of appetite, nausea, vomiting, diarrhea and other gastrointestinal symptoms. There may also be other symptoms of autonomic dysfunction, such as pale complexion, flushing of the skin, sweating, unstable blood pressure, low body temperature or fever, dizziness, syncope and so on.
Examine
Examination of abdominal epilepsy syndrome
1, head magnetic resonance (MRI), CT, blood glucose, blood calcium, cerebrospinal fluid examination, etc., to further identify the cause.
2, EEG examination: paroxysmal fast wave or slow wave, diffuse fast wave or slow wave, array 14 and 6 weeks / second positive phase spike appears. The EEG chart has a focal change of temporal lobe, which is a typical manifestation of this disease. The abnormal rate of conventional EEG is very low, about 10 to 30%. The standardized EEG, due to its appropriate extension of the tracing time, to ensure that various induced tests, especially sleep induction, if necessary, add sphenoidal electrode tracing, thus significantly improving the detection rate of epileptic discharge, can increase the positive rate to About 80%, and the accuracy of the diagnosis of epilepsy is significantly improved.
Diagnosis
Diagnosis and identification of abdominal epilepsy syndrome
Diagnostic criteria
1. There are recurrent paroxysmal abdominal pain, and abdominal pain is often accompanied by a certain degree of disturbance of consciousness.
2. No chest, abdominal cavity, pelvic cavity, spinal cord, peripheral nerves and spirit, physical illness.
3. Authors of epilepsy at the onset of abdominal pain or before the onset.
4. History may have central nervous system diseases.
5. Patients with epilepsy or migraine often have a family.
6. EEG abnormalities, often 14 and 6 weeks / second positive phase spikes appear.
7. Antiepileptic drug treatment has a good effect on abdominal pain.
Need to be differentiated from general gastrointestinal inflammation.
