Have you or your patients ever wondered why patients with absence epilepsy have impaired attention as their major deficit? Is this caused by generalized brain dysfunction, or by changes in specific thalamocortical networks important for normal consciousness? And why is impaired attention seen so often even between absence seizures in these patients? Is this a side-effect of seizure medications, or a sign of underlying interictal network dysfunction?
Dr. Hal Blumenfeld asks for your help in conducting a research study to address these questions. If you have any patients with childhood absence epilepsy or juvenile absence epilepsy, please consider referring them for this study.
Participants will undergo simultaneous EEG-fMRI, attention & behavioral testing to determine which parts of the brain are affected by the spike-wave discharge, and how this may interact with normal mechanisms of attention and consciousness. Data obtained both during and between absence seizures, either on or off medications will all be useful for these investigations.
6 to18 years old
Diagnosed typical childhood absence epilepsy or juvenile absence epilepsy
No history of myoclonic or tonic-clonic seizures
This study is approved by Yale’s Human Investigations Committee
Patients are paid $100 for their participation, receive a photo of their brain, plus reimbursement for any transportation costs
