Pathophysiologic Mechanisms in the Development of Age-Related White Matter Changes of the Brain. Understanding white matter disease: Imaging-pathological correlations in vascular cognitive impairment. It is worth noting that juxtaventricular white matter changes (<3 mm from the ventricular surface), such as ependymitis granularis, are not related to small vessel disease, but rather represent cerebrospinal fluid leak due to disruption of the ependyma10. "However, in many cases, the white matter. The goal is to treat the cause of the damage and stop the disease from getting worse. We'll send you our print magazine 6x per year! This protects the nerve fibres and gives white matter its colour. This can make it especially difficult to exclude other potential diagnoses before MS can be diagnosed.

Some of the most common mimics include migraine and chronic cerebrovascular disease, according to Dr Schiess. MRI brain white matter change in particular the APOE*E4 genotype.5 There has been a wide variation in radiologic terms to describe these white matter changes and in an attempt to unify, the term 'WMH of presumed vascular origin' has been suggested (STRIVE: Standards for Reporting Vascular Changes on Neuroimaging).

These axons connect the neurons of the brain and spinal cord and signal nerve cells to communicate with one another. Each involves problems related to myelin, a fat that covers nerve fibers in the brain. 2002;33(1):45-50. Histology from these lesions shows atrophy of axons and decreased myelin, although MRI overestimates the degree of demyelination with many regions of FLAIR abnormality being due to increased fluid rather than demyelination 17. Non specific white matter changes can be just that, or they can be something else entirely. They also can occur in genetic diseases, toxic disorders, infections, inflammatory conditions, metabolic disturbances, traumatic brain injury, cancer, neoplasia, and hydrocephalus.
