Amyloid plaque is a symptom (assumed, not proven) of Alzheimers.

There is no empirical evidence directly showing it to be a cause.

Perhaps it arrests the typical Alzheimer’s decline, once initiated as a preventative treatment. The amyloid kills neurons and causes permanent structural changes to the brain. It seems to act to stop any further damage occurring, without actually regenerating brain tissue.

Stroke patients can regain function by the retraining of healthy portions of the brain to perform the functions of areas which became injured. Perhaps the losses to Alzheimer can be compensated for in an analogous fashion.
