What are focal seizures?
focal seizures affect the small area of the brain, while generalized seizures affect the entire brain. Also called partial seizures are classified as simple or complex, depending on whether a person is aware of during the episode. A seizure may be unexpectedly for anyone, although it is most common in people suffering from congenital epilepsy, a recent trauma head or strokes. Some of the symptoms of focal seizures include uncontrollable facial movements, abnormal armor or numbness or muscle twitching. Mixed electrical signals in a limited region of the brain cause muscle cramps on one or both sides of the body, strange movements or tics, numbness and blurred vision. The individual could begin to feel sick, dizziness and confused. Episodes can also lead to hallucinations, increased heart rate, fragrance changes or hearing and speaking difficultylties.
Complex focal seizures include the sink of consciousness and memory during or after an episode. PoisonThe notlivec can be black during the seizure and is unable to remember exactly what happened. In most cases, complex focal seizures follow simple seizures. The episode can happen during sleep or awake, and many people state that their seizures create feelings of déjà vu. Simple and complex seizures can take anywhere from a few seconds to about five minutes.
It is possible for people to experience only one simple or complex focal seizures for their lifetime, without any warning or understood medical reason. Individuals who have congenital epilepsy, head injury, strokes or brain tumors have suffered from several focal seizures over time. Bacterial and viral infections can also lead to seizures, and people with meningitis and encephalitis are particularly high risk of epileptic attacks. Short -term or long -term drug and alcohol abuse affects chemicals and electrical signals in mOzka that can sometimes cause outbreak seizures.
Medical evaluation and treatment are very important after a person experiences a focal seizure. The physician usually performs an electroencephalogma (EEG) test to check the abnormal electrical activity in the brain. During the EEG test, specialists connect several small electrodes to the scalp to record electrical signals and represent the exact values on the computer screen. EEG results, along with other scanning medical imaging and blood tests, doctors can help doctors determine the cause of seizures along with the best ways to prevent future episodes.
Many people are prescribed medicines that help control and prevent their epilepsy. Infections are usually treated with antibiotics and may be surgically removed by brain tumors. In addition, anyone can help keep brain health and reduce the risk of seizures by delaying drugs, sufficient sleep, regular exercise and maintaining good diet.
