| 1 | Vascular depression for radiology: A review of the construct,methodology,and diagnosis显示文摘Vascular depression(VD)as defined by magnetic resonance imaging(MRI)has been proposed as a unique subtype of late-life depression.The VD hypothesis posits that cerebrovascular disease,as characterized by the presence of MRIdefined white matter hyperintensities,contributes to and increases the risk for depression in older adults.VD is also accompanied by cognitive impairment and poor antidepressant treatment response.The VD diagnosis relies on MRI findings and yet this clinical entity is largely unfamiliar to neuroradiologists and is rarely,if ever,discussed in radiology journals.The primary purpose of this review is to introduce the MRI-defined VD construct to the neuroradiology community.Case reports are highlighted in order to illustrate the profile of VD in terms of radiological,clinical,and neuropsychological findings.A secondary purpose is to elucidate and elaborate on the measurement of cerebrovascular disease through visual rating scales and semi-and fully-automated volumetric methods.These methods are crucial for determining whether lesion burden or lesion severity is the dominant pathological contributor to VD.Additionally,these rating methods have implications for the growing field of computer assisted diagnosis.Since VD has been found to have a profile that is distinct from other types of late-life depression,neuroradiologists,in conjunction with psychiatrists and psychologists,should consider VD in diagnosis and treatment planning. | Sara N Rushia Al Amira Safa Shehab Jeffrey N Motter Dakota A Egglefield Sophie Schiff Joel R Sneed Ernst Garcon | 2020 | World Journal of Radiology2020，12，5： | 5 |
