Lyketsos et al. [125] found that bright light therapy improved sleep patterns, but it did not lead to improvement of agitated behaviors. Gasio et al. [126] also found that light treatment changed the circadian rhythms of sleep patterns by inducing a small advancement of the circadian rest-activity cycle and inducing an earlier onset of the most restful period of the night. They did not investigate agitation response. Van Someren et al. [127] not only looked at individuals with AD, but included those with severe vision loss or blindness.

Visuospatial Variants of AD In recent years, several studies in humans have shown that many AD patients initially present with prominent visual and visuospatial symptoms. Since NFT and SP formation represent a reliable correlate of the disconnection of certain corticocortical pathways, the identifiable clinical deficits observed in such AD cases may be directly linked to the disconnection that has occurred. In these cases, the visual impairment affects specific aspects of visual function [38–41].
