My wife and I have recently downsized to a housing development primarily for older people. One of those living here is a doctor who has recently retired. He is part of a group developing a process so younger people can determine their chances of developing Alzheimers or other forms of dementia. There are some things out there already and LOTS being developed. Stay in touch with your neurologist, make sure he is up on the latest, and you keep checking on things as well. This is changing fast now and and that speed is only going to get faster.
