Your story is so similar to mine, the only difference being that it was thought that an infection was causing my mother's memory problems. But after the infection was cured, the problems persisted and got worse too. A diagnostic of dementia is always devastating, and you can only take it in bits at a time, slowly absorbing it. For me, learning as much as I could about the disease gave me courage to face it, understanding it more and being less scared of it, like describing a nightmare in the light of day. Best of luck, and do continue to visit this forum.
