Unfortunately for Alice, two of the people she might have confided in at this moment, her mother and Anne, are buried in the graveyard in front of her. Dr. Davis told Alice that her form of Alzheimer’s (the early-onset variety) is strongly connected to genetics, which means at least one person in her family may have had it themselves and passed it onto her. Because of Peter’s alcoholism, Alice never had reason to suspect that his belligerence or strange behavior was the result of Alzheimer’s. So, by a cruel twist of fate, the same alcoholism that indirectly led to the deaths of Anne and Sara may have also prevented him from finding out about his possible Alzheimer’s. Therefore, Alice would also have been unable to take precautionary measures for herself, such as taking medications or making dietary changes to designed to slow its progress.
