Детский аутизм и эпилепсия

Medscape: What is the risk for epilepsy in autism?

Dr. Chez: The risk for epilepsy in autism is 10%-30%, and it usually develops in the teenage or early adult years. Children with autism who are lower functioning, with mental retardation and cerebral palsy, for example, are more likely to develop epilepsy.

In addition, there are many children with autism who demonstrate epileptic spikes when monitored on 24-hour electroencephalography, but who do not manifest clinical epileptic seizures. These may be worth treating with antiepileptic drugs, as treatment may lead to improved behavior and receptive language. If the spikes are in the central temporal region, affecting the language area, I will usually try a trial of valproic acid. Valproic acid may also act as a mood stabilizer in these children, and also inhibits interleukin 1 cytokines, which may provide additional benefit. Other antiepileptic drugs may also be effective, although I have not seen good results with carbamazepine. There is also anecdotal evidence of improvement with the ketogenic diet.

Dr. Pellock: This is a controversial area. There are a few cases where treatment of epileptic spikes has resulted in improved behavior. However, without a clear manifestation of seizures, it is frequently difficult to know whether the short and long-term risks of the medications are really warranted. Clear goals need to be established to determine whether the treatment benefits the child. As a routine, I do not treat isolated spikes on the electroencephalogram, just as I would not treat isolated spikes in any child, with or without autism.
