The possibility that inflammatory processes in the brain contribute to the etiopathogenesis of seizures and the establishment of a chronic epileptic focus is increasingly recognized as a result of supportive evidence in experimental models and in the clinical setting. Prototypical inflammatory cytokines (such as IL-1beta) and "danger signals" (such as HMGB1 and S100beta) are overexpressed in hu...
Encephaloceles are spontaneous or acquired abnormal herniations of the brain into congenital or acquired osseous-dural defects of the skull base or cranial vault. When located in the middle fossa, they may present with medically intractable epilepsy, recurrent meningitis, CSF fistulas, middle ear fluid, or unilateral hearing loss. Bony deficits may involve either the body or the greater wing of...
There is a marked increase in the amount of electrophysiological and neuroimaging works dealing with the study of large scale brain connectivity in the epileptic brain. Our view of the epileptogenic process in the brain has largely evolved over the last twenty years from the historical concept of “epileptic focus” to a more complex description of “Epileptogenic networks” involved in the genesis...
Objectives—Firstly, to compare the findings of interictal F-fluorodeoxyglucose (FDG) positron emission tomography (PET) and of single photon emission computed tomography (SPECT) using Tc-hexamethyl propylene-amine-oxime (HMPAO) and I-iomazenil in localising the epileptogenic cortex in patients who were candidates for epilepsy surgery, but in whom clinical findings, video EEG monitoring (V-EEG),...
PURPOSE To detect the epileptogenic region causing epileptic spasms in an infant with tuberous sclerosis (TS). METHODS We applied a multiple band frequency analysis to video electroencephalographic (EEG) recordings of the infant's scalp. We also performed computed tomography (CT), magnetic resonance imaging (MRI), single-photon emission computed tomography (SPECT), and magnetoencephalography ...
PURPOSE Patients with mesial temporal lobe epilepsy (MTLE) without MRI abnormalities (MTLE-NL) represent a challenge for definition of underlying pathology and for presurgical evaluation. In a recent study we observed significant amygdala enlargement (AE) in 14% of MTLE patients with MRI signs of hippocampal sclerosis. Areas of gray matter volume (GMV) increase could represent structural abnorm...
The aim of this study was to investigate thalamic and basal ganglia (BG) metabolism in temporal lobe epilepsy (TLE) on interictal 18F-FDG PET using standardized uptake value (SUV). Retrospective review of data was undertaken for patients who were surgically treated for medically intractable TLE. All patients underwent 18F-FDG PET, MRI brain and EEG as preoperative workup, and subsequently under...
