Cortical and limbic excitability in rats with absence epilepsy.
The classical cortico-reticular theory on absence epilepsy suggests that a hyperexcitable cortex is a precondition for the occurrence of absence seizures. In the present experiment seizure thresholds and characteristics of cortical and limbic epileptic afterdischarges (AD) were determined in a comparative cortical stimulation study in young and old adult genetically epileptic WAG/Rij, congenic ...
متن کاملPsychiatric comorbidities in temporal lobe epilepsy: possible relationships between psychotic disorders and involvement of limbic circuits.
OBJECTIVE Mounting evidence suggests that the limbic system is pathologically involved in cases of psychiatric comorbidities in temporal lobe epilepsy (TLE) patients. Our objective was to develop a conceptual framework describing how neuropathological and connectivity changes might contribute to the development of psychosis and to the potential neurobiological mechanisms that cause schizophreni...
متن کاملEarly Life Stress as an Influence on Limbic Epilepsy: An Hypothesis Whose Time has Come?
The pathogenesis of mesial temporal lobe epilepsy (MTLE), the most prevalent form of refractory focal epilepsy in adults, is thought to begin in early life, even though seizures may not commence until adolescence or adulthood. Amongst the range of early life factors implicated in MTLE causation (febrile seizures, traumatic brain injury, etc.), stress may be one important contributor. Early life...
متن کاملPre-ictal synchronicity in limbic networks of mesial temporal lobe epilepsy.
PURPOSE We recorded with intracerebral electrodes the onset of limbic seizures in patients with mesial temporal lobe epilepsy (MTLE) to identify the dynamic interactions between the hippocampus (HIP), amygdala (AMY) and entorhinal cortex (EC). METHODS Interactions were quantified by analyzing the interdependencies between stereo-electroencephalographic (SEEG) signals using a nonlinear cross-c...
متن کاملLimbic P300s in temporal lobe epilepsy with and without Ammon's horn sclerosis.
Limbic P300 potentials can be recorded within the mesial temporal lobes of patients with temporal lobe epilepsy (TLE). To delineate possible mechanisms of their generation and pathological alteration, we analysed limbic P300s in 55 TLE patients with and 29 without Ammon's horn sclerosis (AHS) and correlated their amplitudes with neuronal cell counts in 30 histopathological specimens. Limbic P30...
