The relationship between WM lesions (WM) and Postural Instability Gait Disorders (PIGD-PD)in Parkinson's disease patients is largely unknown. We hypothesize that sub-clinical WM pathology may be a major contributing factor to PIGD-PD. We will compare two groups of patients with Parkinson's disease (PD): those with PIGD and patients with dominant tremor (n=120)to assess the role of brain WM changes.
To compare brain WM burden using MRI in PD patients with and without PIGD. Diffusion tensor imaging (DTI) analysis techniques will be applied.We will quantify PIGD-related symptoms including cognitive function, balance and gait and their associations with MRI findings.

The purpose of the study is to evaluate the prevalence of white matter lesions in Chinese migraineurs with and without right-to-left shunt. The aim is to study the relationship among right...
The purpose of this study is to evaluate the efficacy of PDE-3 inhibitor, cilostazol, in prevention and treatment of vascular dementia, in those with brain white matter lesions and vascula...
Studies show that depression is a risk factor for the development of cardiovascular disease. Furthermore there is an increased occurrence of depression in patients with cardiovascular dise...
Rapidly accumulating evidence indicates that the central nervous system (CNS) plays a pivotal role in mobility function with age-associated CNS changes strongly contributing to declining m...
Pharmacological Recruitment of Endogenous Neural Precursors to Promote Pediatric White Matter Repair: Establishing Correlations Between Visual Outcomes, Saccadic Function and MEG Oscillations in Children With Demyelinating Disorders in Comparison to Healt
The neural circuits in our brains require a layer of insulation in order to transmit signals in a rapid and efficient fashion. This insulation is called White Matter and is comprised of a ...
The relation of white matter hyperintense lesions to episodic memory impairment in patients with Parkinson's disease (PD) is still controversial. We aimed at evaluating the relation between white matt...
To investigate spatial heterogeneity of white matter lesions or hyperintensities (WMH).
It is unclear how white matter hyperintensities disrupt surrounding white matter tracts. The aim of this tractography study was to determine the spatial relationship between diffusion characteristics ...
White matter lesions (WMLs), detected as hyperintensities on T2-weighted MRI, represent small vessel disease in the brain and are considered a potential risk factor for memory and cognitive impairment...
Cerebrovascular pathology, quantified by white matter lesions (WML), is known to affect cognition in aging, and is associated with an increased risk of dementia. The present study aimed to investigate...
A condition that is characterized by HEADACHE; SEIZURES; and visual loss with edema in the posterior aspects of the CEREBRAL HEMISPHERES, such as the BRAIN STEM. Generally, lesions involve the white matter (nerve fibers) but occasionally the grey matter (nerve cell bodies).
A cylindrical column of tissue that lies within the vertebral canal. It is composed of WHITE MATTER and GRAY MATTER.
Striped gray and white matter consisting of the NEOSTRIATUM and paleostriatum (GLOBUS PALLIDUS). It is located in front of and lateral to the thalamus in each cerebral hemisphere. The gray substance is made up of the CAUDATE NUCLEUS and the lentiform nucleus (the latter consisting of the GLOBUS PALLIDUS and PUTAMEN). The white matter is the internal capsule.
Loss of the power to comprehend written materials despite preservation of the ability to write (i.e., alexia without agraphia). This condition is generally attributed to lesions that "disconnect" the visual cortex of the non-dominant hemisphere from language centers in the dominant hemisphere. This may occur when a dominant visual cortex injury is combined with underlying white matter lesions that involve crossing fibers from the occipital lobe of the opposite hemisphere. (From Adams et al., Principles of Neurology, 6th ed, p483)
The region of CENTRAL NERVOUS SYSTEM that appears lighter in color than the other type, GRAY MATTER. It mainly consists of MYELINATED NERVE FIBERS and contains few neuronal cell bodies or DENDRITES.
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
