Frontal Lobe 1H MR Spectroscopy of Children With Bipolar Disorder
Previous studies suggest that the administration of lithium, a commonly used agent to treat adult and pediatric bipolar patients, is associated with neuronal inositol decrement (1,2). Lithium strongly inhibits inositol-l-phosphatase, which is the last process in the phospho-inositide cycle. The goal of our study was to assess the effect of lithium treatment on the frontal lobe metabolite levels...
متن کاملFrontal brain lobe impairment in obstructive sleep apnoea: a proton MR spectroscopy study.
Patients with obstructive sleep apnoea syndrome frequently have cognitive deficits, especially related to executive functions, which cannot be fully explained by daytime sleepiness and are partial irreversible after nasal continuous positive airway pressure treatment. The causal mechanism of these cognitive deficits is not yet known, but it has been proposed that they are associated with chemic...
متن کاملProton MR spectroscopy in patients with acute temporal lobe seizures.
BACKGROUND AND PURPOSE Decreases in N-acetyl aspartate (NAA) as seen by proton MR spectroscopy are found in hippocampal sclerosis, and elevated levels of lipids/lactate have been observed after electroconvulsive therapy. Our purpose was to determine whether increased levels of lipids/lactate are found in patients with acute seizures of hippocampal origin. METHODS Seventeen patients with known...
متن کاملfrontal lobe function in chess players
chess is considered as a cognitive game because of severe engagement of the mental resources during playing. the purpose of this study is evaluation of frontal lobe function of chess players with matched non-players. wisconsin card sorting test (wcst) data showed no difference between the player and non-player groups in preservation error and completed categories but surprisingly showed signifi...
متن کاملMultisection proton MR spectroscopy for mesial temporal lobe epilepsy.
BACKGROUND AND PURPOSE Extensive metabolic impairments have been reported in association with mesial temporal lobe epilepsy (mTLE). We investigated whether proton MR spectroscopy ((1)H-MRS) depicts metabolic changes beyond the hippocampus in cases of mTLE and whether these changes help lateralize the seizure focus. METHODS MR imaging and (1)H-MRS were performed in 15 patients with mTLE with a...
