Mental retardation epilepsy

Common Name(s)

Mental retardation epilepsy

Mental Retardation epilepsy refers to a form of intellectual disability that is characterized mainly by below-average mental ability, and sudden periods of continuous shaking of the entire body, seizures. These seizures are caused by a condition called epilepsy. These periods of continuous shaking can be brief and undetectable or extremely obvious and uncontrollable. Females are more prone to have both intellectual disability and epileptic symptoms. Individuals with this form of intellectual disability often will have trouble concentrating on tasks. Like other individuals with intellectual disability, an individual with this condition often has problems with reasoning and solving problems, as well as performing day-to-day tasks. The condition is also often diagnosed during childhood. Doctors diagnose this form of intellectual disability if frequent body shaking is observed. Signs like walking and talking late, slow mastering of basic tasks, and having difficulty remembering things may also suggest this condition in children. Treatment is based on a case-by-case basis and depends on the specific needs of the patient. Brain specialists, neurologists, can provide treatment for the seizures and epileptic symptoms. Treatments include various drugs targeting nerve cells, brain surgery, directly stimulating nerve cells, and changes to one's diet. Doctors seek help from various therapists and community services to provide support and care for families affected by intellectual disability.
