Abstract

BACKGROUND:

It is unclear whether associated cerebrovascular pathology contributes to the clinical spectrum of Lewy body dementia (LBD).

SUMMARY:

The present postmortem 7.0-tesla MRI study investigates the anatomical distribution of cortical microbleeds (CoMBs) in LBD brains with and without associated Alzheimer's disease (AD) and cerebral amyloid angiopathy (CAA). CoMBs predominated in the frontal section of the LBD brains and were associated to severe white matter lesions. No differences were observed when LBD brains with and without AD and CAA were compared.

KEY MESSAGES:

In LBD, there is a specific distribution of CoMBs that is different from that in other neurodegenerative diseases. The increase of frontal CoMBs is not due to the frequently associated AD and CAA features but due to the LBD itself.
