What causes convulsions?This is a common problem in the outpatient clinic of neurology.When it comes to epilepsy, people usually think of scenes such as "losing consciousness, turning eyes, twitching body, and bubbles on the mouth".But in fact, epilepsy is a chronic brain disease with complex causes and diverse symptoms.Today, let’s see what other symptoms may be manifestations of epilepsy besides typical convulsions.Why do epilepsy have so many symptoms?

　　We all know that the brain is the "command center" that controls various functions of the body. It has a precise structure and clear functional partitions, including language areas, motor areas, sensory areas, visual areas, auditory areas, and complex areas that deal with emotions and spirits.Epilepsy seizures are temporary neurological dysfunction caused by abnormal brain neurons and excessive synchronized discharge.Different locations of abnormal discharges determine the diversity of clinical manifestations of epilepsy.

　　Here are the atypical symptoms that may indicate epilepsy:

　　Stay in a daze, be stunned, interrupted movement

　　When I was in class or work, I suddenly became dazed and stunned, my eyes were dull, and I didn't respond to the calls of people around me, and suddenly returned to normal after a while.If these seemingly daily behaviors occur frequently and are accompanied by small movements such as groping and lip smacking, they may be epilepsy, such as absenteeism or an autopsy of focal origin.

　　The hand trembles briefly and the item falls

　　This is a common manifestation of myoclonus seizures, such as sudden shaking of hands while writing or eating, causing the pen or chopsticks to fall.Despite the clear awareness, this symptom is often overlooked and thought to be an accidental mistake.Sometimes, this jitter can be confused with Parkinson's disease or idiopathic tremor in the family, and it is not diagnosed with epilepsy until years later.

　　Memory fragments, brain blankness

　　Many people have had the experience of suddenly "breaking" such as forgetting what just happened, or doing something but suddenly forgetting it.This is often used as a joke among young people, and in the elderly, it may be mistaken for Alzheimer's disease.In fact, epilepsy seizures can also cause this symptom.However, stress, lack of sleep, fatigue, tension, anxiety and other conditions can also cause similar symptoms, which can usually be relieved after rest and relaxation.If these symptoms occur frequently and there is no other cause, beware of the possibility of epilepsy.

　　A sense of familiarity, a sense of stomach qi rise

　　Sometimes I suddenly feel that the current scene seems familiar, or accompanied by stomach discomfort, and feel that gas is rising.This may be a precursor to temporal lobe epilepsy, and if these symptoms often occur simultaneously or successively, detailed examinations should be considered.

　　Audio-silience, vision, fear

　　Auditory hallucinations and vision are common symptoms of epilepsy, especially occipital and temporal lobe epilepsy.Visual or auditory hallucinations may occur, such as seeing irregular figures, colorful lines or strangers, animals, etc., or hearing non-existent sounds.These symptoms may cause fear and excessive behavior.Epilepsy and some other diseases may cause these manifestations and require professional examinations to clarify the cause.

　　What causes convulsions?You may be worried about knowing that these diverse symptoms may indicate epilepsy.But if it occurs occasionally and there is no other discomfort, it will be relieved after rest, and usually there is no need to worry too much.If symptoms appear frequently and there is no clear cause, or if family and friends notice abnormalities, or have a history of head trauma or brain disease, seek medical treatment in a timely manner for professional examination and evaluation to avoid delaying diagnosis and treatment.
