(left panel) and rendered images (right panel) showing results of the ALFF analysis. Upper: compared with normal controls, patients at baseline showed significantly decreased (blue) ALFF only in bilateral ventral medial frontal cortex (P < 0.05 corrected). Middle: compared with baseline, patients after six weeks showed significantly increased (red) ALFF mainly in bilateral prefrontal and pariet...

Aging effects on blood-oxygen-level-dependent (BOLD) functional MRI (fMRI) have been studied using task induced hemodynamic responses with controversial findings. The present study systematically investigated the normal aging effect in the visual cortex using 3 indices of low frequency fluctuations of resting state BOLD fMRI, i.e., amplitude of low frequency fluctuations (ALFF), regional homoge...

Depressive symptoms are common in Parkinson's disease (PD), but the neurophysiological mechanisms of depression in PD are poorly understood. The current study attempted to examine disrupted spontaneous local brain activities and functional connectivities that underlie the depression in PD. We recruited a total of 20 depressed PD patients (DPD), 40 non-depressed PD patients (NDPD) and 43 matched...

BACKGROUND The cerebellum is of potential interest for understanding adaptive responses in motor control in patients with multiple sclerosis because of the high intrinsic synaptic plasticity of this brain region. OBJECTIVE To assess the relative roles of interactions between the neocortex and the cerebellum using measures of functional connectivity. METHODS A role for altered neocortical-ce...

Cortical reorganization has been demonstrated in the motor network that mediates performance of a motor task in patients with multiple sclerosis. How this network responds to motor training is not known. This study examined functional MRI (fMRI) activation patterns associated with performance of a motor task, consisting of repetition of directionally specific voluntary thumb movements, before a...

sjogren-larsson syndrome (sls) is an inherited autosomal recessive neurocutaneous disorder with congenital ichthyosis, spastic diplegia or quadriplegia and mental retardation. we report a case of sjogren-larsson syndrome with clinical profile (mental retardation, ichthyosis, spastic diplegia) and mri findings such as seen in multiple sclerosis (ms). so this rare syndrome can be another differen...

conclusions these results suggest that treadmill training and yoga practice improved ambulatory function, fatigue and mood status in the individuals with mild to moderate ms. patients and methods thirty-one ms patients, all female with mean of age of 36.75 years and expanded disability status scale scores (edss) of 1.0 to 4.0 were recruited. subjects were randomly assigned to one of the three g...

multiple sclerosis (ms) is a demyelinating neuro- inflammatory autoimmune disease of the central nervous system. genetic predisposition has long been suspected in the etiology of this disease. the association between mthfr polymorphisms and ms has been ivestigated in different ethnic groups. we investigated the association between mthfr c677t and a1298c missense variants and ms in 180 patients ...

background: hormones can play a significant role in the pathogenesis of multiple sclerosis (ms). the aim of this study was to compare levels of ghrelin, leptin, and testosterone hormones of ms patients with healthy subjects, and assess the relationship between levels of peptide hormone and sex hormones in ms patients. methods: 35 ms patients with definite relapsing remitting multiple sclerosis ...
