Interictal alterations of thalamic metabolic concentration ratios in migraine without aura detected by proton magnetic resonance spectroscopy

Interictal and postictal contingent negative variation in migraine without aura.

Cortical hyperexcitability is thought to explain the more enhanced contingent negative variation (CNV) amplitudes and impaired CNV habituation that have been found during the interictal period in migraine without aura. These CNV characteristics have been shown to normalize to the level of healthy controls during an attack. This study aimed to replicate the interictal findings, and additionally ...

Assessment of Cerebellar Metabolites Levels in Athletes Compared to Non-Athlete by Proton Magnetic Resonance Spectroscopy

Background: Adaptability to exercise training can increase the plasticity of the brain, and whether this can be due to a beneficial change in the neurometabolites, is uncertain. The purpose of this study was to evaluate basal metabolic concentrations of cerebellum, including N-acetyl aspartate (NAA) and Cholin(Cho) in athletes and compare them with non-athlete subjects. Materials and Methods: I...

Cerebral metabolic abnormalities in COPD patients detected by localized proton magnetic resonance spectroscopy.

STUDY OBJECTIVES To investigate changes in the cerebral metabolism of patients with COPD, using localized in vivo proton magnetic resonance spectroscopy ((1)H MRS), and to evaluate the clinical significance of cerebral metabolic abnormalities in COPD patients. PATIENTS AND METHODS Seventeen symptomatic COPD patients and 21 age-matched healthy volunteers participated in this study. All subject...

Cerebral metabolic abnormalities in congestive heart failure detected by proton magnetic resonance spectroscopy.

OBJECTIVES Using proton magnetic resonance spectroscopy, we investigated cerebral metabolism and its determinants in congestive heart failure (CHF), and the effects of cardiac transplantation on these measurements. BACKGROUND Few data are available about cerebral metabolism in CHF. METHODS Fifty patients with CHF (ejection fraction < or = 35%) and 20 healthy volunteers were included for thi...
