The cause of sudden convulsions in children has not been determined, but a number of factors can cause them to occur. The main factors include stress, genetic factors and brain abnormalities. Stress can cause convulsions in children is a common phenomenon, when children are under some stress, the body’s ability to withstand it is not acceptable, this time the body will have some reactions, and convulsions are a situation. This cause of convulsions will generally recover on its own and does not require treatment. Some twitches may be caused by heredity, and genetic mutations can cause some patients to suffer from such diseases, which are caused by genes, and such diseases can only be controlled but not cured. Brain abnormalities may also be the cause of tic disorder, or it may be due to some mental illnesses that cause such symptoms, such as depression. Some studies suggest that sudden twitching may be related to neurotransmitters, which are chemicals in the brain that transmit nerve signals to cells, and that the levels of neurotransmitters are disrupted when twitching is treated. The cause of pediatric convulsions is uncertain, but stress-related is the most common, followed by genetic mutation-induced and neurological abnormalities. Those caused by stress can usually recover without treatment, but those caused by genetic and neurological abnormalities are difficult to treat.
