Stages of Alzheimer’s Disease: Stage 1 No Impairment
Depending on the source, some say there are seven (7) stages of Alzheimer’s disease while others say there are three (3). The Alzheimer’s Association says that there are seven (7) stages of Alzheimer’s disease. I will cover each stage of Alzheimer’s in separate posts.
Stage 1, according to the Alzheimer’s Association, is No Impairment (normal function). No evidence is apparent to a health care professional during a medical interview. In my post on What is Alzheimer’s Disease? I mentioned three ways that doctors determine how a diagnosis is made –
- Lab tests
- Neuropsychological testing (extensive assessment of thinking and memory skills)
- Brain scans
Apparently, Stage 1 only involves an interview since there is no evidence or reason for more extensive testing at this point. So why a Stage 1? If Stage 1 is normal functioning with no impairment, then it seems to me in order to determine a Stage 1, it is can only be determined AFTER a person has been diagnosed with Alzheimer’s disease. There is no abnormality in Stage 1. So after a person has been diagnosed, then we can go back and say this person with Alzheimer’s was in Stage 1.
On the other hand, it might be possible to detect a Stage 1 if you lived with someone or you know someone very well … a loved one whom you can detect mild memory loss or mild cognitive impairment or other signs and symptoms such as personality changes, all of which may indicate a future Alzheimer’s diagnosis. Or, if you personally feel that something is not right with your memory, then you may possibly be in Stage 1 of Alzheimer’s disease, but Stage 1 means that you are still functioning normally. At this point, though, from a medical standpoint, an Alzheimer’s diagnosis is not possible. Other problems such as anxiety disorders, bipolar disorders, sleep problems, depression, or medications could also point to Alzheimer’s disease, but that would be conjecture at this time.
If you detect dementia, though, and if you are a future caregiver, you need to remember to most importantly take care of yourself. But it also gives you time to get things in order and prepare for the future. Through our continuous journey, I hope we can learn what to expect (even though each case is unique) and follow the Scout motto: “Be Prepared.”
