The beta amyloid theory is pretty tired at this point since the correlation between plaques and Alzheimer's is only moderate.
Imo Alzheimer's is probably more related to the brain falling into dysdunctional, self reinforcing patterns of synaptic connectivity.
Neural plaques might exacerbate this problem by disrupting connectivity, but clearly the brains of many people with plaques learn to route around this damage to retain functionality.
- bransonf 7y ago> self reinforcing patterns of synaptic connectivity Any sources for this? I’d be very interested to read the literature on this.

The connectome dysregulation theory is my own, it hasn't appeared in the scientific literature as of yet due to our inability to perform fine mapping of synaptic connections without microtoming a cadaver brain.
- kortex 7y agoThat's a cool theory. The brain tries pretty hard to maintain criticality (hard as in, disruptions cause it to return to that setpoint quickly). It's possible that inability to recover or maintain optimal processing criticality can lead to corruption of the connectome. https://www.sciencedaily.com/releases/2019/10/191007113314.htm https://www.sciencedaily.com/releases/2019/10/191007113314.h...
