Need a lot more info. To even start to give you an answer, i would need to know a lot more about you: your age, medical conditions, why you think you might be getting alzheimer's. And that's just to start. To actually make the diagnosis requires a thorough work-up including, at least, a good history, a brain scan, comprehensive psychometric testing, lab work, and a physical exam. And there's even more possibly.
Depends . I cannot answer this with out knowing the symptoms .
