Amyloid accumulation in Alzheimer disease is response to chronic stress.
2004 SEP 1 - (NewsRx.com & NewsRx.net) -- Amyloid accumulation in Alzheimer disease is a response to chronic stress.
"Amyloid deposition within cerebral vessels, or cerebral amyloid angiopathy (CAA), is common in advanced age and even more common in Alzheimer disease. CAA may be complicated by lobar intracerebral hemorrhage, while rare kindreds of autosomal dominant CAA also show propensity for intracerebral hemorrhage, due to germline mutations in specific amyloidogenic precursor proteins and apparent compromise of structural integrity of the blood vessel wall due to marked amyloid deposition. The relationship between cerebral amyloid angiopathy and cognitive dysfunction, however, is less clear," scientists in the United States report.
"While cognitive dysfunction in familial CAA is likely related to prodigious amyloid deposits and vascular luminal compromise (e.g., hereditary cerebral hemorrhage with angiopathy-Dutch type (HCHWA-D)), cerebral amyloid angiopathy with intracerebral hemorrhage often presents sporadically in cognitively intact elderly patients," stated Rudy J. Castellani at Michigan State University and collaborators at Case Western Reserve University.
"Moreover, while about 80% of subjects with Alzheimer disease have demonstrable amyloid beta within blood vessel walls at autopsy, the vast majority of these fail to suffer clinically relevant intracerebral hemorrhage during life. The remaining 20% manage to progress and die of their disease with virtual no amyloid within blood vessels."
"Thus, the role of amyloid beta deposits in cerebral vessels as regards cognitive function on the one hand, and tendency for hemorrhage on the other, ...
