Symptoms of intellectual disability caused by pediatric epilepsy include memory impairment, dyscalculia, disorientation, and disuse. 1. Memory impairment. Familiar environment feels strange, and certain familiar things suddenly cannot be recalled. 2. Calculation disorder. Simple addition, subtraction, multiplication and division errors. 3. Poor orientation. Inability to recognize familiar people, not recognizing familiar places at preschool age, etc. 4. Disuse. Errors in timing and sequence when doing fine and complex movements, clumsier movements, etc. When pediatric epilepsy develops, if it is not controlled in time, it will lead to irreversible damage to the neurons in the brain and cause retardation of intellectual development and a significant decline in learning ability.
