I also have no sense of direction, but I've pretty much always been that way.
My daughter thinks I'm just a ditz or have adult ADHD, but I don't know if she is just trying to make me feel better.
When I read these forums and see just how awful dementia is and the horrible things caregivers go through, I am terrified. I get so paralyzed with fear that I check things I do multiple times. For instance, I will open the dishwasher or washing machine more than once to make sure the detergent compartments are closed. I will have my spouse check simple math for me when making change or figuring out a tip at a restaurant. I feel like I should talk less so I don't say something bizarrely wrong, like getting the wrong month or season. I'm driving myself nuts!
Articles say that if a person is concerned about his/her memory, then that is a sign that the person probably is developing cognitive problems. BTW, I am 67 and do not have a family history of dementia.
