This perspective would suggest that interventions to limit neurodegenerative environmental exposures (e.g. "Black holes" on T1 weighted imaging are not usually seen in the spinal cord but gadolinium enhancement of acute cord lesions does occur. White matter hyperintensities are of presumed vascular origin and are frequently observed in older adults as well as in patients with AD (Brickman, Muraskin, & Zimmerman, 2009; Dadar et al., 2015). New imaging techniques present an opportunity to examine white matter pathology in great detail in younger populations. There is no specific treatment for white matter lesions. White matter hyperintensities are lesions in the brain that can be detected by T2-weighted MRI on which these lesions show up with increased brightness. White matter hyperintensities proliferate as the brain ages and are associated with increased risk for cognitive decline as well as Alzheimers disease and related dementias.

In a population-representative birth cohort of individuals now in midlife, we found that WMHs are (i) common, (ii) associated with cognitive abilities in childhood and midlife and (iii) associated with cognitive decline from childhood to midlife. The https:// ensures that you are connecting to the With other imaging techniques, a white matter lesion may appear as a black hole, which indicates damage to the axons. The risk of dementia is expressed as age- and sex-adjusted hazard ratios. White matter hyperintensities (WMHs) are a frequent finding on T2-weighted MRI of the brain in elderly individuals, but their prevalence and severity in younger asymptomatic populations is less well studied. Specifically, the addition of childhood SES as a covariate attenuated the relationship between childhood IQ and WMH volume because SES and IQ are known to be closely related during childhood. Study members in all panels are grouped into deciles defined by SDs from the mean WMH volume (mm3), ranging from 1.5 to 1.5 SDs in 0.5 SD increments. There also is emerging evidence that treating high blood pressure may reduce white matter lesions associated with vascular disease.

Background: White matter hyperintensities of presumed vascular origin (WMH) are a common finding in elderly people and a growing social malady in the aging western societies. One reason for this inconsistency could be that older adults have accumulated decades of irrevocable age-related tissue damage. Thus, our findings suggest that WMHs may be a surrogate biomarker for identifying individuals in midlife who are at risk for future clinically significant cognitive decline or ADRD. White matter lesions are one of the most common incidental findings on brain scans.
