Data from the largest analysis to date of amyloid plaques showed they can appear 20 or 30 years before dementia symptoms.
Scientists believe TSEs are caused by the buildup of abnormal forms of prion protein that causes sponge-like holes in the brain. Using special mice, NIAID researchers have found a new prion disease that does not make holes in the brain.Instead, the disease damages brain blood vessels in a process called cerebral amyloid angiopathy, a symptom typical of Alzheimerâs disease.sing special mice, NIAID researchers have found a new prion disease that does not make holes in the brain.
