Are amyloid plaques a natural response to head injury, somewhat like
the formation of scar tissue or the setting of bones after breakage?
A synapse surrounded by an amyloid plaque would at least seem, at
least inferring from its structural properties, to have a greater
physical strength of connection than a synapse that was not surrounded
by an amyloid plaque.
