Comorbidity of cerebral amyloid angiopathy and Alzheimer's disease. Clinical case analysis

Abstract

The development of cognitive impairment in old age is often caused by overlapping neurodegenerative and cerebrovascular changes which have a mutually aggravating clinical effect. In recent years, the problem of cerebral amyloid angiopathy (CAA), which is one of the variants of such an interaction, has gained importance. Despite the frequent occurrence of this pathology in the elderly, a unified approach to the treatment of these patients has not yet been developed, especially taking into account the frequent combination with other nosological forms. CAA is a disease associated with both Alzheimer's type neurodegeneration and cerebrovascular pathology. The article presents a clinical case illustrating this situation and discusses the diagnostic algorithm in detail. The characteristics of the pathogenesis and clinical manifestations of CAA and the link between neurodegenerative and cerebrovascular pathologies are discussed.
