I have read around here that some people with cognitive decline or dementia travel well, but that has not been my experience. My family members did not travel well and even a short drive from home could cause confusion, agitation, and disorientation. It seems those with mild impairment fare better.

Hopefully, the treatments will be of help. But, I think preparing for things to progress is reasonable. My dad had Alzheimer’s and it developed slowly, but my cousin’s was rapid. The adjustment is challenging, imo. I hope you have support.
