Stage 1: Normal Function
This stage is pretty much as it sounds, your memory and cognitive abilities are only as limited as you've trained them. Considering that Alzheimer's is usually diagnosed at around the age of 65, you still have your whole life ahead of you if you're young.Stage 2: Very Minor Impairment
Technically, this is the first stage of the Alzheimer's progression. At this stage, the person will only experience minor memory lapses and small everyday confusion. It's nearly impossible to detect Alzheimer's at this stage since the only symptoms can easily be mistaken for stress or sleep deprivation. Considering how minor they are, you'll hardly notice them; it could be as simple as those short lapses you get when you enter a room, or even which cabinet you keep you bowls in.Stage 3: Minor Impairment
At this point, your confusion and forgetfulness may have increased by a few folds. By now, it would be visibly noticeable to the people around you that you've been becoming increasingly forgetful/confused. At stage 3, it's probable that you'll have slight difficulty remembering new things that you've just learned, such as names and words. (It could be as simple as stuttering for about three seconds while trying to recall a person's name) along with trouble organizing and planning for the future.While possible, it is still difficult to detect AD at this stage.
