There are so many correlations of vascular injury with dementia that it seems obvious that the fibrils would not be causative but rather correlated to dementia.

There are so many correlations of vascular injury with dementia that it seems obvious that the fibrils would not be causative but rather correlated to dementia. I personally believe that dementia is related to or caused by repeated small vascular injuries that eventually cause degradation of the brain. That is, transient ischemic attacks that are completely subclinical aside from the injury that is visible after autopsy.
