What are the factors of seizures and what are the characteristics of seizures

Epilepsy is also a relatively common disease, and there are many causes of epilepsy, 1. Genetics; 2. Traumatic brain injury; 3. Brain tumor; 4. Cranial surgery; 5. Intracranial infection; 6. Cerebrovascular disease; 7. Prenatal and intrapartum injuries; 8. Metabolic disorders; 9. Poisoning; 10. Hypoxia; 11. Congenital diseases; 12. Hereditary diseases; 13. Demyelinating diseases, etc. All of the above ** cause epilepsy**, I hope these answers will be helpful to friends who don't understand epilepsy in life. It is hoped that patients with epilepsy should go as soon as possible**, and for epilepsy**, Western medicine will be used first**, and surgery can be selected for more serious conditions or if the drug ** is not effective**.

Hello! Grand mal seizures are generally manifested as, sudden loss of consciousness, falling to the ground, head back and limbs twitching, some patients roar due to diaphragm spasm, bluish complexion, dilated pupils, foaming or drooling at the mouth, eyes turned up, some are accompanied by incontinence, it generally takes more than ten minutes to wake up after the seizure, the patient can not recall the seizure process, and the whole body is in pain and weakness.

Absence seizures are also known as petit seizures: they include simple absence seizures and complex absence seizures.

Simple absence seizure: manifested as the patient suddenly stops the activity at that time, the object in the hand falls, the consciousness is temporarily lost, the eyes are staring and not moving, lasting about 5 15 seconds, no aura and local symptoms, immediately awake afterwards, does not affect work or study, has no memory of the seizure, and can have dozens or even hundreds of seizures per day.

Complex absence seizures: In addition to being stunned, they are accompanied by other movements, such as blinking, smacking lips, rubbing fingers, etc., for more than 10 seconds.

Epilepsy is a chronic brain disease caused by various types of **. It is characterized by repetitive, episodic, rigid, and landslide-like transient central nervous system dysfunction caused by neuronal overfiring. The pathogenesis of epilepsy is complex, and it is mainly believed to be caused by the imbalance of excitability and inhibition in the central nervous system, which is closely related to the imbalance of neurotransmitters, ion channels, glial cells, genetic and immune abnormalities, and other factors.

The main causes of epilepsy are primary and secondary. The primary nature of epilepsy refers to the fact that the current detection methods have not found the acquired epilepsy, and for this epilepsy, genetic factors may be the main epilepsy. So epilepsy is hereditary.

<> secondary to epilepsy. There are many secondary epilepsy, mainly due to some factors that cause damage to the cerebral cortex, such as infection, pregnancy, nutritional and metabolic diseases, cerebrovascular diseases, trauma, etc. Intravascular thrombosis, cerebral edema, accumulation of pathogens and their metabolites in the cerebral cortex caused by central nervous system infections such as encephalitis, meningitis, brain abscess, and neurocysticercosis can cause nerve cell necrosis, degeneration, and inflammatory cell infiltration, thereby affecting the stability of nerve cell membranes and affecting the permeability and normal function of nerve cells. Abnormal electrical discharges that cause seizures.

Pregnancy problemsDuring pregnancy, especially in the first trimester of pregnancy, infection, non-conformity with rational medication, receiving a large amount of radiation, or having perfect high sex, placental abruption, placental aging and other diseases will affect the fetus, if it affects the development of the nervous system, such as brain malformations, loss of corpus callosum, gray matter ectopic and other congenital abnormalities, it is prone to epilepsy.

In addition, various birth injuries, severe asphyxia, forceps delivery, etc. can also cause fetal brain ischemia and hypoxia, resulting in brain damage and epilepsy in the future. Nutritional metabolic diseases such as: hypoglycemia, glucose is known as the main energy of the brain**, and the brain group has almost no glucose reserves, once hypoglycemia occurs, the brain function is first impaired, the damage starts from the cerebral cortex, and then spreads to the cerebral cortex, which can cause abnormal neuronal firing and induce seizures.

In addition, the loss of sodium-water replacement and acid-base balance can also easily induce seizures, and the excess water of extracellular fluid and the decrease of sodium are a state of low permeability, and the water moves within the cells, and the edema of the cells and brain cells leads to an increase in intracranial pressure, which can lead to seizures.

There are many causes of seizure failure, most of the patients are found to have a lesion of the central nervous system, or the patient has a space-occupying lesion of the central nervous system, and the symptoms are: impaired consciousness, limb rigidity; Numbness of tics or somatosensory sensations, pins and needles, memory impairment, emotional disturbances, etc.

Excessive mood swings, unhealthy diet, genetics, viral infections, and hail immune system diseases; A: When you have a seizure, your lips will turn purple, your fingers will clench, your face will be pale, and you will suddenly feel dizzy and in shock.

Epilepsy is due to the disorder of the cerebral nervous system, and some brain trauma will directly affect the brain function, and if it is intracranial inflammation, edema, and long tumors, it may also lead to epilepsy.

There are a lot of this**Extremely complex, and there are a variety of factors that affect the onset of the disease, you go to Kunming Junhai to find He Changqi to check it, to determine**, symptomatic**. No. 172, Ankang Road, Xishan District, Kunming City, Yunnan Province. This is the address.

What factors can cause epilepsy in patients: 1. Acute and chronic renal failure, hypoglycemia, hypocalcemia, hypertensive encephalopathy, pancreatic adenoma, hyperthyroidism; 2. Vitamin B6 deficiency; 3. Various systemic infections; 4. Long-term use of hypnotics; 5. Sudden withdrawal from alcoholism; 6. Sudden discontinuation of anti-epileptic drugs; 7. Carbon monoxide poisoning can induce epilepsy. Only by paying attention to your own care and maintenance can you fundamentally control the seizures of epilepsy and return yourself to a healthy body.

Hormones Some women with epilepsy have seizures related to the menstrual cycle, often with an increased number of seizures during the premenstrual period and menstrual period. This is mainly related to changes in the levels of estrogen and progesterone in the body. If the patient is predisposed to do so, the relationship between seizures and menstrual periods should be documented in detail and a specialist should be consulted (see Epilepsy and Women).

The pathogenesis of epilepsy is complex. The imbalance between excitation and inhibition in the central nervous system leads to seizures, which are mainly related to changes in ion channel neurotransmitters and glial cells.

Abnormal ion channel function.

Ion channels are the basis for the regulation of excitability in excitable tissues in vivo, and mutations in the genes encoding them can affect the function of ion channels, leading to the occurrence of certain genetic diseases. At present, it is believed that many human idiopathic epilepsy is caused by ion channelopathy, that is, defective genes encoding defective ion channel proteins, among which the correlation between sodium, potassium and calcium channels and epilepsy is relatively clear.

Neurotransmitter abnormalities.

Epileptic discharges are closely related to neurotransmitters, and under normal circumstances, excitatory and inhibitory neurotransmitters remain in equilibrium, and neuronal membranes are stable. Too many excitatory neurotransmitters or too few inhibitory transmitters can cause an imbalance between excitation and inhibition, making the membrane unstable and producing epileptic discharges.

Glial cell abnormalities.

The electrolyte balance of the neuronal microenvironment is fundamental to the maintenance of normal neuronal excitability. Glial cells play an important role in maintaining the living environment of neurons. Seizures can occur when the ability of astrocytes to take up glutamate or aminobutyric acid is altered.
