Autism does not usually cause convulsions. Convulsions in children with autism are often considered to be related to febrile convulsions (convulsions due to high fever), seizures, and other causes. Autism is a developmental disorder that does not usually cause convulsions. Children with autism mainly show a lack of interest in social interaction, such as reluctance to communicate with others, always avoiding others, and difficulty in establishing friendships with children of the same age. Convulsions in children with autism may be related to febrile convulsions, for example, when the child suffers from certain infectious diseases, it is easy to have high fever symptoms, when the body temperature rises sharply, if the fever is not reduced in time, it is likely to induce febrile convulsions, which may cause convulsions. In addition, children with convulsions may also be associated with epileptic seizures. Some children with autism may have a history of epilepsy, and when stimulated by certain undesirable factors, seizures may be induced, resulting in convulsions, which may also be accompanied by foaming at the mouth and distorted eyes. Children with autism should actively cooperate with their doctors for targeted treatment and conditioning to prevent excessive health hazards.
