The literature concerning medication effects on cognitive functioning and test results is reviewed, along with guidelines for treatment-team members to help assure proper prescribing and monitoring of medication to achieve maximum therapeutic effect with minimal side effects. (Author/DLS)

This commentary reviews studies of children with Landau-Kleffner Syndrome (LKS) and autistic regression (AR) and concludes that they are two distinct entities with different epileptic profiles and that the treatment modalities used in LKS cannot be expected to yield a therapeutic effect in AR. Multiple Subpial Transection is discussed. (Contains…

The treatment of seizure disorders and EEG epileptiform abnormalities without epilepsy in children with autism spectrum disorders in considered within the context of the relationship epilepsy and epileptiform disorders to language, behavior, and cognition. The use of anticonvulsants to treat epileptiform discharges thought to be producing…
