Cerebral amyloid angiopathy (CAA) is common in elderly individuals, especially those affected with Alzheimer's disease. To investigate whether the presence of severe CAA (SCAA) in the brains of demented patients was associated with a higher burden of old microinfarcts than those with mild CAA (MCAA), 18 brains with SCAA were compared to 21 brains with MCAA. Immunohistochemistry for CD68 was employed to highlight old microinfarcts in tissue blocks from various brain regions. Old microinfarcts, manually counted by light microscopy, were present in 14 of 18 SCAA brains, and in 7 of 21 MCAA brains (P = 0.01, 2-tailed Fisher’s exact test). The average number of old microinfarcts across geographic regions in each brain ranged from 0 to 1.95 (mean rank 24.94, sum of ranks 449) in the SCAA group, and from 0 to 0.35 (mean rank 15.76, sum of ranks 331) in the MCAA group (P = 0.008, 2-tailed Mann-Whitney U test). Frequent old microinfarcts in demented individuals with severe CAA may contribute a vascular component to the cognitive impairment in these patients.
