Relationship between white matter hyperintensities, cortical thickness, and cognition.
BACKGROUND AND PURPOSE White matter hyperintensities (WMH) are associated with clinically heterogeneous symptoms that cannot be explained by these lesions alone. It is hypothesized that these lesions are associated with distant cortical atrophy and cortical thickness network measures, which can result in an additional cognitive impairment. Here, we investigated the relationships between WMH, co...
متن کاملWhite matter hyperintensities and cognition: testing the reserve hypothesis.
OBJECTIVE White matter hyperintensities (WMH), visualized on T2-weighted MRI, are thought to reflect small-vessel vascular disease. Much like other markers of brain disease, the association between WMH and cognition is imperfect. The concept of reserve may account for this imperfect relationship. The purpose of this study was to test the reserve hypothesis in the association between WMH severit...
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...
متن کاملStructural neuroimaging in Alzheimer's disease: do white matter hyperintensities matter?
The targeted brain dysfunction that accompanies aging can have a devastating effect on cognitive and intellectual abilities. A significant proportion of older adults experience precipitous cognitive decline that negatively impacts functional activities. Such individuals meet clinical diagnostic criteria for dementia, which is commonly attributed to Alzheimer's disease (AD). Structural neuroimag...
متن کاملcomparison of brain white matter hyperintensities in methamphetamine and methadone dependent patients and healthy controls
background previous studies have proven the development of white matter hyperintensities (wmh) in methamphetamine and opioid users. opiates and methamphetamines (ma) are the most common addictive agents in iran. the adverse effects of drugs on the cns is of concern to specialists and researchers, and given that the neurotoxicity associated with methamphetamine is greater than opioids, it is hyp...
