Epilepsy, which is extremely harmful to a child’s body. When a child is diagnosed with epilepsy, the main concern of parents is whether the seizures will endanger the child’s intelligence and normal growth and development. Detailed answers to these questions will be given. Does epilepsy affect a child’s development? No generalizations can be made about this question. In most cases, both developmental delay and epilepsy are the result of congenital or acquired brain disorders, and are two parts of the same symptom at the same time, without any cause-and-effect relationship. Of course, if your child has frequent and severe seizures, his or her development does become delayed. This is because excessive abnormal discharge activity is constantly impeding normal brain function, and frequent seizures can cause hypoxia and damage to the brain. Therefore, it is especially important to control abnormal discharges and seizures early. A significant number of children with developmental delay improve after the seizures resolve. Does epilepsy affect a child’s intelligence? Most children with epilepsy have the same intelligence as normal, and only a minority of patients have lower intelligence than normal. There are several factors that affect the intelligence of children with epilepsy: 1. Related to the etiology of epilepsy Some epilepsy is complicated by brain dysplasia, and some are congenital metabolic abnormalities that are often complicated by mental retardation. 2. Different types of epilepsy have different degrees of impact on intelligence Primary epilepsy such as athetoid epilepsy and benign partial epilepsy in children often have little impact on intelligence. Infantile spasms, a type of epilepsy, is associated with more than 90% intellectual disability. 3. The frequency of seizures also has an effect on intelligence The more frequent the seizures, the greater the incidence of mental retardation. A study proved that in pediatric epilepsy, if the average number of seizures per year is less than 11, mental retardation accounts for only 28%; in children with epilepsy who have seizures every day, mental retardation is as high as 76%. The younger the age of onset, the greater the impact on intelligence. According to a survey conducted in previous years, more than 70% of children with seizures within one year of age were mentally retarded, while only about 40% of children with seizures between the ages of 9 and 15 were mentally retarded. The side effects of a large number of long-term antiepileptic drugs may also affect the patient’s intelligence, but the effect of correct and reasonable antiepileptic treatment on intelligence is not significant. It is important to diagnose and standardize the treatment of childhood epilepsy as soon as it is detected. Generally speaking, 70%-80% of children with epilepsy can have their seizures controlled with treatment. The recurrence rate in children with epilepsy is lower than that in adults. If the condition is controlled in time, the impact on the child’s intelligence and development can be reduced.
