I do not have words to say how sorry I am for you Steve Martin and Shaun. This is a very sad disease for sure and I have a soft spot for those who I hear are going through it. Steve, for you to experience this so young in your marriage, it must have been an extremely hard this past year. My only advice is to take care of yourself, and the next time you meet with your doctor, ask if there would be any benefit to having your wife go on a ketogenic diet. With the help of a nutritionist, it may help. There was a study done in 2020 in the Journal of geriatric psychiatry and neurology titled Ketogenic Diet for the Treatment and Prevention of Dementia: A Review. The summary is that this way of eating has the potential to lower systematic inflammation in the body and allow malfunctioning body functions to potentially heal. I’m not saying it’s the cure to all dementia, but possibly could help since you caught it early and may prolong the decline. As to how to prepare for such a life, Shaun had good advice of getting your finances and all that legal stuff in order now and tie in a close family member to help you. Plan to adjust your life if things get worse and do not feel bad if you have to get a part time nurse to help out at the house or potentially taking her to a full time care facility. My family had all the good intentions that they could muster to help my grandfather with dementia out, but eventually it just was way too much on a huge support network of people to even handle and he went to a care facility. He is doing well there and is living out life the best way he can.
