Alzheimer’s Disease Linked to Superficial Siderosis. What Does it Mean? | ALZFORUM

People with Alzheimer’s disease are nearly seven times more likely than
other people to harbor superficial siderosis —a serpentine pattern
of blood deposits that snake the brain’s surface, researchers reported
in the February 25 Neurology. The blood dregs, which show up on MRI
scans, have previously been linked to amyloid-related vascular injury.
The new work, led by Frederik Barkhof at VU University Medical Center in
Amsterdam, extends the superficial siderosis link to AD, and may
provide a useful radiological marker for vascular amyloid pathology that
plagues some AD patients.
