In chapter 3, one key topic that struck me was learning about acetylcholine. Acetylcholine is a neurotransmitter that plays a role in arousal, selective attention, sleep, and memory. When someone has Alzheimer's disease, these transmitters are getting destroyed. They have had medication that can alleviate some of the symptoms, but can that lead to a pathway of treatment, or at least, prevention?
This struck me because my grandma has Alzheimer's. Although it is still the early stages of the disease, I am really interested in anything that can help. But so many questions still remain; if they could find a cure, would it reverse the effects? Or would the patient still have some memory loss? Is there specific activities that can boost acetylcholine production in the brain? And are we moving towards a cure, or just prevention?

It is an interesting idea, we can slow symptoms but we can't prevent it. I have the same questions as you, how can this be? I have no clue on the matter but I'm guessing that if there is a way to slow the symptoms, we are on the right track to prevention. In terms of reversing the process, I don't see how that would be possible. I believe once the damage is done its done and there is nothing we can do about it.
