ScienceDaily (Apr. 19, 2011) — A new study found that treatment-resistant epilepsy (TRE) is common in idiopathic autism. Early age at the onset of seizures and delayed global development were associated with a higher frequency of resistance to antiepileptic drugs (AEDs). Full findings appear online in Epilepsia, a journal published by Wiley-Blackwell on behalf of the International League Against Epilepsy (ILAE).
