Dementia is a chronic neurodegenerative disorder characterized by progressive cognitive loss. Alzheimer's disease (AD) and the Lewy body disease are the two most common causes of age-related degenerative dementia. Visuo-cognitive skills are a combination of very different cognitive functions being performed by the visual system. These skills are impaired in both AD and dementia with Lewy bodies (DLB). The aim of this review is to evaluate various studies for these visuo-cognitive skills. An exhaustive internet search of all relevant medical databases was carried out using a series of key-word applications, including The Cochrane Library, MEDLINE, PSYCHINFO, EMBASE, CINAHL, AMED, SportDiscus, Science Citation Index, Index to Theses, ZETOC, PEDro and occupational therapy (OT) seeker and OT search. We reviewed all the articles until March 2013 with key words of: Visual skills visual cognition dementia AD, but the direct neurobiological etiology is difficult to establish., Dementia of Lewy body disease. Although most studies have used different tests for studying these abilities, in general, these tests evaluated the individual's ability of (1) visual recognition, (2) visual discrimination, (3) visual attention and (4) visuo-perceptive integration. Performance on various tests has been evaluated for assessing these skills. Most studies assessing such skills show that these skills are impaired in DLB as compared with AD. Visuo-cognitive skills are impaired more in DLB as compared with AD. These impairments have evident neuropathological correlations, but the direct neurobiological etiology is difficult to establish.
