[Q]: Question: Are lobar microbleeds associated with a decline in executive functioning in older adults?
Answer: Lobar microbleeds, a marker of cerebral amyloid angiopathy, are associated with an accelerated rate of executive function decline. The presence of cerebral amyloid angiopathy may be an important source of cognitive decline in aging. Future work should examine how cerebral amyloid angiopathy interacts with neurodegenerative processes, such as Alzheimer's disease.
