Age was the only independently associated factor for white matter hyperintensities (OR = 1.11 for each 1-year age increase; 95% CI, 1.04-1.19).

Abbreviations: WMH, white matter hyperintensities; PVH, periventricular hyperintensities; DWMH, deep subcortical white matter hyperintensities. Statistical analysis The characteristics of our study were summarized using means and standard deviations (SD) for continuous variables and frequencies and percentages (%) for categorical variables.

White matter hyperintensities are common in MRIs of asymptomatic individuals, and their prevalence increases with age from approximately 10% to 20% in those approximately 60 years old to close to 100% in those older than 90 years. 3 They are more common in individuals with a history of cognitive impairment, dementia, or cerebrovascular disease.

2021-02-18 · Increased white matter hyperintensities occurred frequently among patients with behavioral-variant frontotemporal dementia and Alzheimer’s disease in a cross-sectional MRI study published in Background: Hypertension and white matter hyperintensities (WMH) are mutually associated risk factors for cognitive impairment. However, age may modify the associations between hypertension and WMH, and their links to cognitive impairment. 2021-03-25 · White matter hyperintensity volume, type and shape correlated with an increased risk for mortality and ischemic stroke among patients with manifest arterial disease, according to findings from the 2013-05-09 · Background White matter hyperintensities (WMH) lesions on T2/FLAIR brain MRI are frequently seen in healthy elderly people. Whether these radiological lesions correspond to irreversible histological changes is still a matter of debate. We report the radiologic-histopathologic concordance between T2/FLAIR WMHs and neuropathologically confirmed demyelination in the periventricular, perivascular 2020-10-08 · White matter hyperintensities (WMH) are very frequent in older adults and associated with worse cognitive performance. Little is known about the links between WMH and vascular risk factors, cortical β-amyloid (Aβ) load, and cognition in cognitively unimpaired adults across the entire lifespan, especially in young and middle-aged adults. 2018-07-02 · Background White matter hyperintensities (WMHs) are frequently detected in migraine patients.

4 According to Charles DeCarli, the director of UC Davis Alzheimer's Disease Center, these areas may indicate some type of injury to the brain, perhaps due to decreased blood flow in that area. White matter hyperintensities can be caused by a variety of factors including ischemia, micro- hemorrhages, gliosis, damage to small blood vessel walls, breaches of the barrier between the cerebrospinal fluid and the brain, or loss and deformation of the myelin sheath. The effect of white matter hyperintensities on UPDRS total score and bradykinesia subscore was indirectly mediated by dopamine transporter availability in the posterior putamen, whereas the axial sub-score was directly affected by white matter hyperintensities. White matter hyperintensities (WMHs) are clinically silent abnormalities visible in deep or periventricular white matter on CT or MRI. They are particularly apparent on FLAIR MRI, which is a T2-weighted sequence where the CSF signal is suppressed. The study results suggested that white matter hyperintensities (WMH) “are partly independent of vascular pathology and associated with the neurodegenerative process,” according to the researchers. White matter hyperintensities can be caused by a variety of factors, including ischemia, micro- hemorrhages, gliosis, damage to small blood vessel walls, breaches of the barrier between the cerebrospinal fluid and the brain, or loss and deformation of the myelin sheath.

White matter hyperintensities proliferate as the brain ages and are associated with increased risk for cognitive decline as well as Alzheimer’s disease and related dementias. As such, white matter hyperintensities have been targeted as a surrogate biomarker in intervention trials with older adults.
