Reduced occipital cerebrovascular reactivity is unique to cerebral amyloid angiopathy

Takeaway

  • Diminished occipital cerebrovascular reactivity is a unique feature of cerebral amyloid angiopathy that is not seen in Alzheimer’s disease.

Why this matters

    These findings could support the diagnosis of cerebral amyloid angiopathy as currently available beta-amyloid markers do not accurately differentiate between cerebral amyloid angiopathy and Alzheimer’s disease.
