Positron emission tomography in basic epilepsy research: A view of the epileptic brain

Abstract

The neurobiological processes that result in epilepsy, known as epileptogenesis, are incompletely understood. Moreover, there is currently no therapy that effectively halts or impedes the development or progression of the condition. Positron Emission Tomography (PET) provides valuable information about the function of the brain in vivo, and is playing a central role in both clinical practice and research. This technique reliably reveals functional abnormalities in many epilepsy syndromes, particularly temporal lobe epilepsy. Unfortunately, epileptogenesis is extremely difficult to study in human patients who usually present with established epilepsy, rather than at the early stages of the pr..
