Maelezo
Cerebral small vessel disease (SVD) is commonly detected in elderly individuals, and patients with stroke or neurodegenerative disease. Features seen on neuroimaging include recent small subcortical infarcts, lacunes, white matter hyperintensities, perivascular spaces, microbleeds, and brain atrophy. Previous studies indicated that SVD was associated with an increased risk of stroke and stroke recurrence, cognitive deficits, physical disabilities, and mortality. However the pathogenesis of SVD is largely unknown. Little is known about how SVD lesions contribute to neurological or cognitive symptoms, and the association with risk factors. Recent data sugessted concomitant SVDs and retinopathy is associated with a profile of vascular cognitive impairment. In this study, the investigators try to explore the new pathological mechanism of SVD, the new predictors for SVD progression, and the association with cognitive Impairment, based on digital retinal images and brain multimodal imaging technique.
