Q: People in the history of how the understanding of epilepsy?
A: Epilepsy (Epilepsy) is a brain neurons sudden abnormal discharge, leading to transient cerebral dysfunction in a chronic disease. The seizures (epileptic seizure) refers to the neuronal abnormalities and clinical phenomenon of excessive discharge super-synchronous caused. Characterized in that a sudden and transient symptoms due to abnormal discharge portion neurons in the brain is different and there are a wide variety of performance. It may be a motion sensory nerve or autonomic nervous system with or without the degree of alertness or consciousness changes.
Q: Epilepsy is a brain something wrong with it?
A: Indeed. Epilepsy is the human brain function there is a problem. Our thinking, memory, learning, emotion, movements are controlled by the nervous system, the composition and function of the nervous system is extremely complex. The existence of the nervous system and other body systems as well as between the parts of the nervous system are complex and diverse, interconnected network, this network, the brain's command to spread the various executive departments, to complete a variety of functions. For a better understanding of epilepsy, we should understand the three basic knowledge about the brain: the brain by electrical activity to work. Under normal circumstances, the brain in an orderly manner weak bioelectric impulses, these electrical impulse conduction along nerve cells in the neural network, and is referred to by some chemical neurotransmitters between the various parts of the nervous system the nervous system to establish a link between each other and other systems. When nerve cells sudden, abnormal electrical activity, it may cause seizures. Different parts of the brain to assume different functions. Therefore, understanding the origin of seizures in different brain regions, its clinical manifestations are different. Doctors often asked in detail about when the performance of seizures in patients, in order to help determine which part of the brain problem. The human brain left and right hemispheres. We left hemisphere controls the right side of the body, while the right hemisphere is in charge of the function of the left side of the body. Therefore, doctors often will ask questions such as the following: When you attack the left arm or right arm pumping? Head and eyes deflection to which side? ...... order to determine which side of the hemisphere is a problem.
Q: What is epilepsy?
A: Epilepsy is one of the most common disorders neurology, nervous system (brain) involvement of a complex form of expression, which is based on recurring sudden, short-term impact can be made as epilepsy brain function characterized by a large group of diseases general. Like tuberculosis patients often have a cough, fever and night sweats as a common feature of epilepsy is repeated seizures clinic. Typically, doctors have at least two epileptic seizures when seizures consider the diagnosis of epilepsy, seizures, and these must be "spontaneous seizures", that is not due to specific causes appear in the patient. For example, febrile seizures, alcohol withdrawal seizures when, not "spontaneous attack", but "induced seizures." The reason epilepsy patients with seizures can be brain damage suffered, such as previously suffered from encephalitis, a brain tumor, or head trauma; there may be episodes in patients with congenital tendency of quality, such as certain hereditary epilepsy; also, where possible could not find a clear reason, this situation is not uncommon.
Q: What is a seizure?
A: Seizures are a group of clinical symptoms due to the sudden cluster of brain cells, abnormal discharge caused. It is a concrete manifestation of symptoms. Depending on the performance, seizure may be classified into various types, e.g., grand mal seizures, absence seizures, tonic seizures like. Some seizures are obvious, such as generalized grand mal seizures; some episodes are mild, careful observation will not be missed, such as hands myoclonic seizures; some attack only the patients themselves can feel it, others can not perceive, for example, or a sense of deja vu visual hallucinations. Different types of seizures are not the same damage to the human body, such as systemic grand mal harm is relatively large, and petit mal (ie typical absence seizures) even if frequent, the human body seems to be no significant damage.
Q: Seizures and Epilepsy is the same thing?
Answer: It is not. In short, the seizures are specific symptoms, while the concept of epilepsy is a disease level. You can use this analogy: someone with tuberculosis disease (the equivalent of epilepsy), the patients presented with fever, coughing and night sweats (the equivalent of seizures). Epilepsy (a disease) is characterized by recurrent seizures appear on clinical (symptoms of the disease), ie patients showed repeated seizures, the doctor can consider the diagnosis of epilepsy.
Q: Why is there a seizure?
A: As mentioned earlier, the nature of seizures is abnormal discharge of brain cells. In simple terms, there are two aspects of the human brain power to stop the discharge and promote discharge, under normal circumstances, to maintain a good balance between the two. In promoting the discharge of excessive force or prevent the discharge power weakened, the balance between ie break, resulting in abnormal discharge, thereby causing seizures clinically. Abnormal discharge occurring site, and mode of transmission path difference determines the onset of different content. When there is two or more times of spontaneous seizures, he called the seizure.
Q: mother suffering from uremia appeared twice convulsions during dialysis, which can be diagnosed epilepsy do?
A: I can not diagnose epilepsy. Sometimes, patients suffering from serious diseases, such as lung disease, kidney disease, liver disease or trauma after receiving surgery, seizures may occur. In this case, seizure is caused due to the underlying disease caused by brain dysfunction. Seizures often disappear after improvement of the underlying disease. Therefore, these "induced seizures" situation is generally not diagnosed with epilepsy.
Q: I have only one episode, you need to see a doctor?
A: Yes. After the first attack, usually require a comprehensive assessment of the nervous system, find the cause seizures. Your doctor will decide whether drug therapy after a first episode based on the assessment results.
Q: How do I know my symptoms are seizures?
A: Not all of the onset of symptoms are seizures. Some people see blood or fainted when hearing the bad news, maybe even accompanied by tics performance; some people due to arrhythmia or syncope due to low blood sugar becomes mind is unclear. These cases are not seizures. Since the onset of symptoms clear whether a seizure is an important first step in the diagnosis of epilepsy, doctors need to carefully understand the specific circumstances of attack. For example, how to attack background appear? It is under attack awake or asleep? Before the onset of whether patients with abnormal sensation (aura)? When the mind is clear attack patients? Whether the face or limbs twitching? Convulsions bilateral symmetry is only one side of the limb or twitch? How is the performance of the onset of evolution? Attack lasted how long? What is the status of patients after the onset? Whether the tongue bite or urinary incontinence? Later episodes in patients with or without memory? There are several forms of attack? How the various frequency of episodes? What causes seizures was motivated? ...... since the determination whether a particular symptom is seizures requires strong expertise, specialist should be done. As patients and their families, the primary task is to provide accurate and comprehensive information attack aspects of medical history, and other medical situations as much as possible.
Q: Why sometimes after brain injury was a long time before seizures occur?
A: In many cases did not appear seizures after brain injury immediately, but a gap of several months or even several years after the occurrence. Unfortunately, at present we do not know why, scientists are actively conduct research.
