Epilepsy has the potential to affect intelligence, but it is analyzed on an individual basis. Epilepsy is a chronic condition and is one of the more common disorders in neurology. In most people with epilepsy, if the seizures are not frequent, the condition does not usually affect intelligence. However, if the seizures are frequent, the condition may damage the neurons, which in turn may lead to mental decline, especially in children who are growing and developing. This condition persists for a long period of time and can also cause hypoxia and ischemia in the brain, which can also have an effect on intelligence. Therefore, in order to prevent epilepsy from causing persistent damage to the body, it is important to cooperate with the doctor for active treatment.
