I'm 66 years young and Diabetic. I do take a number of medicines for my diabetes, but I have also noticed that the memory is very forgetful at times is this cause I'm 66 or the meds. I know you don't know what I take but I find being 66 is kind of young to be so forgetful?
You may or may not want to know the answer. But answers are always better than questions and doubts, particularly if there's something that can be done. Even if this is a degenerative condition heading towards dementia, there are often ways that they can help increase brain function and delay the onset of Alzheimer's and dementia.
And you might just find that it is something minor that can be corrected. How great would that be?!
