White Matter Pathology in Parkinson's Disease (PD)

2014-08-27 03:17:00 | BioPortfolio

Summary

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.

Description

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.

Medical and Biotech [MESH] Definitions

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.
