Correlation between H-1 MRS and memory before and after surgery in mesial temporal lobe epilepsy with hippocampal sclerosis

Purpose: Proton magnetic resonance spectroscopy (H-1 MRS). which can demonstrate neuronal loss and gliosis, may be used as a sensitive tool for lateralization of temporal lobe epilepsy (TLE). Although the correlation between the memory functions and H-1 MRS has been investigated, its predictive value after surgery has not been studied previously. This Study evaluated memory and H-1 MRS values of medically intractable patients with mesial TLE and hippocampal sclerosis (MTLE-HS) before and after selective amygdalohippocampectomy (SAH)

Memory in patients with drug-responsive mesial temporal lobe epilepsy and hippocampal sclerosis

Purpose: Mesial temporal lobe epilepsy associated with hippocampal sclerosis (MTLE-HS) is the most common of the antiepileptic drug (AED)-resistant seizure syndromes that are remediable mostly with surgery, although a small group of patients have benign prognosis with fewer seizures. Material-specific memory impairment is an important feature in these patients and may be related to both the structural abnormality and the frequent seizures. In this study, we investigated the relation between memory deficit and HS by taking seizure frequency into account
