Cerebral perfusion changes reliably reflect changes in neuronal activity. Our aim was to obtain new insights into the pathophysiology of complex partial seizures (CPS) in patients with hippocampal sclerosis (HS) using interictal and ictal single photon emission computed tomography (SPECT). We studied 24 patients with refractory temporal lobe epilepsy (TLE)(More)
PURPOSE To present the first ictal fluorodeoxyglucose-positron emission tomography (FDG-PET) evidence of the hypothalamic origin of gelastic seizures in a patient with a hypothalamic hamartoma (HH) and to raise the issue of true dual pathology related to this entity. METHODS Ictal FDG-PET was acquired during an episode of status gelasticus with preserved(More)
The authors compared ictal SPECT injection performed by medical personnel with self-injection ictal SPECT in six patients with refractory temporal lobe epilepsy. Self-injection was safe and started faster. Self-injection subtraction ictal SPECT coregistered to MRI (SISCOM) was localizing in three patients who had a complex partial seizure, but only one of(More)
