Seizures and Epilepsy—Autism Toolkit

ICD10

  • F84.0

What are seizures?

Seizures are caused by an attack of too much activity in the brain. A child who has a seizure may lose consciousness (black out) for a short time; shake strongly all over his body; have unusual, repeated body movements; have “drop attacks”; have seizures in his sleep; or stare blankly into space.

What is epilepsy?

Epilepsy is defined as 2 or more seizures when the child does not have a fever or another medical reason for the seizure.

How common are seizures in children with autism spectrum disorder (ASD)?

About 1 in 4 children with autism spectrum disorder (ASD) has seizures. Seizures usually start in early childhood or the early teen years. Children with ASD who have a lower IQ or cannot speak have the highest risk for seizures.

How does a doctor diagnose seizures?

Children with ASD often have repetitive movements and staring episodes. A doctor can often tell which repetitive behaviors might be seizures. A test called electroencephalography (EEG) can record electrical activity in the brain and help a doctor check for seizures. Electroencephalography can record a seizure that happens only when the EEG equipment is on your child. The EEG cannot record seizures that happen at other times. Sometimes, it is necessary to do EEG over a longer period of time to see if movements or spells are seizures.

Should every child with ASD have electroencephalography?

Most children with ASD do not need EEG. A doctor will likely ask for an EEG if a child is having spells that the doctor thinks are seizures or if a child has recently lost language or other skills. Electroencephalography is usually done with the child awake and then asleep. There are different types of EEGs, some completed during a shorter visit to the hospital, others done overnight in the hospital or at home. The doctor will decide the type of EEG that is appropriate for each child.

How are seizures treated?

In most cases, medicines called anticonvulsants can help control seizures. These medicines can usually lower the number of seizures, but they cannot always get rid of them. Some children have EEG results that are not normal, but they do not have obvious seizures. It is not yet clear if in those situations anticonvulsants can help.

One of 2 specific types of cannabidiol oil (known as CBD oil) is now US Food and Drug Administration approved for treatment of seizures in children with 2 kinds of severe epilepsy (Lennox-Gastaut and Dravet syndromes). Cannabidiol oil is not approved for management of ASD in children who do not have these specific conditions.

There have been cases of measles in NC, with exposures in Chapel Hill, Durham, and Wake County. We can give the MMR dose early to families who want it. This applies to infants 6-12 months who have not gotten a dose yet or kids under 4-5 years who have not gotten their second MMR dose. At this time, the NC DHHS and health departments are not recommending this unless traveling or living in an area with sustained transmission. Two doses of the MMR vaccine are highly effective (97%) at preventing measles infections. At CHCAC, children receive their first dose at 12 months of age and a second dose at 4 years of age, ensuring they are fully protected as soon as possible, in accordance with the most up-to-date AAP recommendations. Some infants aged 6 months to 11 months who travel internationally or in high-prevalence areas may need a dose to protect them; however, they still require the 1-year and 4-year-old doses as well. If you are ever concerned about a possible exposure to measles, please CALL before entering our office. DO NOT ENTER the office. NC DHHS keeps a list of areas with measles exposures here . This is a highly contagious illness, and special precautions must be taken to prevent spread. The virus can be present in the air for 2 hours after an infected person is in the room, and 90% of susceptible patients can be infected. As always, if you have questions, we are here to help make sense of it all!
