In the field of medicine, there is a phenomenon that is like a lightning storm deep in the brain, which suddenly strikes but deeply affects people's concern and sympathy, and that is epileptic seizures. It is like a silent symphony, with each chapter revealing the subtle balance and moments of loss of control in the brain's neural network.
1、 Causes of epileptic seizures
1. Congenital/hereditary causes
Genetic factors: Some epilepsy cases have a familial predisposition and are associated with genetic mutations or chromosomal abnormalities. Congenital brain developmental abnormalities: including cortical dysplasia, gray matter ectopia, gyrus malformation, neuronal migration defects, etc. Fetal or neonatal brain injury: such as intrauterine infection, fetal distress, hypoxia, premature birth, low birth weight, birth injury, etc.
2. Acquired causes
Brain trauma: Severe impact or trauma to the head may cause brain tissue damage, leading to epileptic seizures. Brain infections and inflammations: such as encephalitis, meningitis, parasitic infections, etc. Cerebrovascular disease: cerebral hemorrhage, cerebral infarction, cerebral vascular malformation, etc. Brain tumors or other space occupying lesions: Tumors that compress neurons or alter the chemical environment in the brain may cause epilepsy. Poisoning and drug reactions: such as alcohol, drugs, improper use of certain medications, or allergic reactions. Metabolic diseases: such as hypoglycemia, electrolyte imbalance, hepatic encephalopathy, uremia, etc. Sleep and wakefulness cycles: episodes of sleep deprivation, excessive fatigue, and deep sleep are more common. Sensory stimulation: Strong visual, auditory, and olfactory stimuli can serve as triggering factors, especially in susceptible populations. Emotional fluctuations: Great joy, anger, shock, and strong emotional stimulation may also trigger epileptic seizures. Physiological changes: such as changes in female menstrual cycle, hormone levels, etc.
2、 Symptoms of epileptic seizures
1. Generalized seizures
Generalized tonic clonic seizures: Patients suddenly lose consciousness, first experiencing muscle tension and rigidity throughout the body, followed by rhythmic muscle twitching throughout the body. During the seizure, symptoms such as closed teeth, foaming at the mouth, pale complexion, incontinence of urination and defecation, and rolled eyes may occur. After the attack, the patient may fall into a state of unconsciousness and wake up feeling tired and confused. Absence seizure: manifested as a brief loss of consciousness, where the patient appears to be in a daze, ceasing ongoing movements, unresponsive to external stimuli, lasting for a short period of time, and quickly returning to their original activities without leaving any lingering symptoms. Muscle spasm: Short, lightning like muscle contractions, which may be sudden twitches of a single muscle or multiple muscle groups. Dystension attack: Sudden weakness in the muscles of the entire body or part of the limbs, which may cause the patient to fall.
2. Partial seizure
Simple partial seizure: The patient is conscious and the seizure only affects a part of the brain, which may manifest as limb twitching, numbness, pain, visual, auditory, or taste abnormalities. Complex partial attacks: At the beginning of the attack, local symptoms are obvious, followed by or at the beginning of consciousness disorders, which may be accompanied by automatisms such as smacking, groping, repeating certain movements, etc. Partial seizures followed by generalized seizures: Initially a partial seizure, it then spreads to the entire brain and evolves into a generalized seizure.
3、 How to treat epilepsy?
1. Drug therapy is the preferred method for treating epilepsy, and approximately 70% of epilepsy patients can effectively control seizures through appropriate drug treatment. Doctors will comprehensively select suitable antiepileptic drugs based on the type of epileptic seizure, patient age, gender, accompanying diseases, and drug side effects, such as phenytoin sodium, carbamazepine, lamotrigine, sodium valproate, and oxcarbazepine. Drug therapy emphasizes individualization and regularity, requiring timely and quantitative administration according to medical advice, and adjusting medication and dosage according to efficacy and side effects.
2. Surgical treatment
For patients with drug-resistant epilepsy or those with clear structural lesions such as brain tumors or focal cortical dysplasia, surgical treatment may be considered. Surgical methods include lesion resection, corpus callosum incision, stereotactic surgery, vagus nerve stimulation, etc., with the aim of removing or isolating the lesion that causes epileptic seizures.
3. Neuromodulation therapy, such as vagus nerve stimulation, is a minimally invasive treatment method that does not require direct resection of the lesion. It uses implanted devices to send electrical pulses to the vagus nerve to alleviate or reduce epileptic seizures.
4. Ketogenic diet therapy
Ketogenic diet is a high-fat, low carbohydrate, and moderate protein diet therapy that changes the energy metabolism pathway in the body, allowing the brain to use ketone bodies instead of glucose for energy supply, thereby reducing epileptic seizures. Ketogenic diet therapy is commonly used for children with refractory epilepsy who have ineffective or ineffective drug treatment. Before implementation, it needs to be evaluated and guided by a professional medical team.
4、 How to prevent the occurrence of epilepsy?
1. Genetic counseling and eugenics
For couples with a family history of epilepsy, premarital genetic counseling is important and may be necessary to avoid consanguineous marriage. Pregnant women should avoid giving birth at an advanced age, pay attention to health care during pregnancy, avoid harmful factors such as viral infections and radiation, undergo regular prenatal check ups, and if necessary, undergo genetic screening and genetic testing.
2. Prevention in infancy
Prevention of various infectious diseases in infancy, especially encephalitis, meningitis and other central nervous system infections. Control the fever of infants and young children, treat febrile diseases in a timely manner, and avoid the occurrence of febrile seizures, as repeated severe febrile seizures may increase the risk of epilepsy in the future.
3. Healthy lifestyle
Maintain a regular schedule, ensure adequate sleep, avoid staying up late and overworking. Maintain a balanced diet, avoid hunger, overeating, and consuming foods that may trigger epilepsy. Stay away from alcohol, drugs, and certain medications that may trigger epilepsy. Moderate exercise, avoid high-intensity, extremely stimulating or dangerous activities, and reduce the risk of accidental injury.
4. Chronic disease management
Patients with chronic diseases such as hypertension, diabetes and heart disease should be checked regularly to effectively control blood pressure, blood sugar and blood lipid levels and prevent cerebrovascular accidents. Preventing traumatic brain injury, wearing safety helmets, and ensuring safe driving can help reduce the risk of traumatic epilepsy.
5. Medication treatment
For patients diagnosed with epilepsy, they should strictly follow the doctor's prescription for medication, undergo regular check ups, adjust the treatment plan in a timely manner, and not stop or change the dosage of medication without authorization.
May all epilepsy patients recover soon, regain confidence and courage in life, and live their own brilliance and beauty. At the same time, I also wish all those who care about and support epilepsy patients good health, success in their dreams, and contribute to building a more harmonious and beautiful society together.
