Cortical Lewy body disease is a pathological observation rather than a distinct clinicopathological entity. Cortical Lewy bodies (CLB) are typically found in Parkinson’s disease and dementia with Lewy bodies (DLB), although they may also occur in other neurological disorders. Unlike their brain stem counterparts, CLB are less distinctive and are poorly visualised using conventional histochemical methods. The protein -synuclein is the main component of Lewy bodies and the related dystrophic Lewy neurites¹; immunohistochemistry using antibodies raised against this protein has greater sensitivity in demonstrating Lewy pathology within the cerebral cortex than histochemical methods and anti-ubiquitin immunohistochemistry.

Dementia is a common occurrence in Parkinson’s disease, with a prevalence of 20–40% in cross sectional studies,^2,3 but a cumulative incidence approaching 80%.⁴ The clinical phenotype of this dementia shares many features with DLB. In neither condition, however, has the relation between the presence of CLB and the dementing . . . [Full text of this article]
