BACKGROUND AND PURPOSE An increased prevalence of disabilities is being observed as more preterm infants survive. This study was conducted to evaluate correlations between brain MR imaging measurements taken at a term-equivalent age and neurodevelopmental outcome at 2 years' corrected age among very low-birth-weight infants. MATERIALS AND METHODS Of the various brain MR imaging measurements o...

Reducing the number of false positive discoveries is presently one of the most pressing issues in the life sciences. It is of especially great importance for many applications in neuroimaging and genomics, where datasets are typically high-dimensional, which means that the number of explanatory variables exceeds the sample size. The false discovery rate (FDR) is a criterion that can be employed...

Introduction: The process of aging is essentially defined by a decline in various physical and mental processes that take place within the human body. Healthy aging is not only accompanied by a decline in cognitive processing, but also motor function, in particular an increase in the slowness of movements and a loss of coordination. Functional brain imaging has indicated that age-related change...

1. Patterns of brain activation were measured with whole brain echo-planar functional magnetic resonance imaging (fMRI) at 3.0 Tesla in healthy children (N = 6) and in one child with a left-hemisphere encephalomalacic lesion as sequellae from early stroke. 2. Three cognitive tasks were used: auditory sentence comprehension, verb generation to line drawings, and mental rotation of alphanumeric s...

Functional near-infrared imaging (fNIR) is a non-invasive, convenient, safe and stable imaging method to test biological state. It can obtain the biological tissue hemodynamic data, thus becoming a powerful tool to measure brain activities, mental workload, metabolism and cognitive activities state. First of all, we introduced the characteristics and current situation of fNIR in this article. T...

MR imaging is typically obtained during the work-up of patients who have undergone allogeneic hematopoietic stem-cell transplant who present with unexplained change in mental status, amnesia, or seizures. Although the differential diagnosis is broad in this setting, the presence of T2 prolongation limited to the medial aspect of one or both temporal lobes with or without associated reduced wate...

Neuropsychological assessment is a performance-based method to assess cognitive functioning. This method is used to examine the cognitive consequences of brain damage, brain disease, and severe mental illness. There are several specific uses of neuropsychological assessment, including collection of diagnostic information, differential diagnostic information, assessment of treatment response, an...

Posterior reversible encephalopathy syndrome is a condition characterised by headache, confusion, seizures and visual disturbances. This can occur in high blood pressure and eclampsia. Magnetic resonance imaging is the gold standard. Usually the symptoms tend to resolve after a period of time. It was fi rst described by Hinchey in 1996. We had a 22-years-old primi that has delivered a caesarean...

The objective of this study was to evaluate in individuals applications at clinical high risk of mental disorder with Diffusion Tensor Imaging (DTI-MRI). This provides an important opportunity for pathological mechanisms of Schizophrenia Disease (SD) and Alzheimer Disease (AD), related to mental disorder. All disease is associated with abnormal activity distributed spatially in neural systems w...

Subacute combined degeneration (SCD) is known as myelopathy due to vitamin B12 deficiency. SCD always involves the posterior and lateral columns of the spinal cord, with the neuropathologic change showing vacuolation of the white matter. We describe 2 patients who presented with ataxic gait, impaired proprioception over limbs, and even mental change due to vitamin B12 deficiency. Magnetic reson...
