Research progress of the characteristics of abnormal visual pathway and its clinical application in patients with Alzheimer's disease

Abstract:

Alzheimer's disease (AD) is the most common form of dementia in the elderly who is characterized by progressive and irreversible loss of multidimensional cognitive function. Visual impairment is one of the features in AD and its high-risk population mild cognitive impairment (MCI) patients, and visual pathway dysfunction is associated with the underlying mechanism. Neuroimaging can reveal subtle changes in visual pathway in AD spectrum patients, which could help to early recognize and intervene in the progress of AD. In this article, we will review the progress of characteristics of abnormal visual pathway and its clinical application in AD spectrum patients.
