White matter hyperintensities on brain magnetic resonance in systemic sclerosis.
OBJECTIVE To evaluate the brain status of patients with systemic sclerosis (SSc). METHODS Fourteen female patients with SSc aged 24-74, with a disease duration of 1-12 years and without other relevant systemic diseases, were enrolled. All patients and an age matched female control group (CG) of 14 clinically normal subjects, underwent brain magnetic resonance examination at 1.5 T; spin echo p...
متن کاملWhite matter hyperintensities in migraine
Case-control studies showed that migraine is associated with ischemic stroke. Studies assessing the prevalence of white matter lesions (WML) in migraine however, reported conflicting results, possibly attributable to selection bias by recruiting only severe cases. We conducted a population-based MRI study of migraineurs with aura (N=161), migraineurs without aura (N=134) and controls (N=140), 3...
متن کاملMTI of white matter hyperintensities.
The severity of tissue changes associated with incidental white matter hyperintensities (WMH) in the elderly cannot be sufficiently determined by conventional MRI. We, therefore, performed a regional analysis of the magnetization transfer ratio (MTR) maps obtained on a 1.5 T scanner from 198 neurologically asymptomatic participants of the Austrian Stroke Prevention Study (mean age 70, age range...
متن کاملAttenuation of brain white matter hyperintensities after cerebral infarction.
Cerebral Infarction Brain white matter hyperintensities (WMHs) on MR imaging are reported to increase with age and do not decrease, though their pathogenesis is not well understood. Here, we report an interesting case in which a patient showed attenuation of WMHs at 1 year after the incidence of cerebral infarction. A 78-year-old female outpatient with hypertension and dyslipidemia presented wi...
متن کاملWhite matter hyperintensities and normal-appearing white matter integrity in the aging brain
White matter hyperintensities (WMH) of presumed vascular origin are a common finding in brain magnetic resonance imaging of older individuals and contribute to cognitive and functional decline. It is unknown how WMH form, although white matter degeneration is characterized pathologically by demyelination, axonal loss, and rarefaction, often attributed to ischemia. Changes within normal-appearin...
