When people are experiencing dementia and/or Alzheimer’s, they lose not only memory skills but rational thinking skills as well. When people lose their memory skills, they may become unable to recall what has happened minutes ago, days ago, or even years ago, and so will inadvertently misinterpret and draw the wrong conclusions about what’s true and happening in the present. (And trying to jog the memory of someone who’s lost memory skills won’t work, just like pointing to something won’t help if someone’s lost vision skills.) However, because they are also losing their rational thinking skills, it doesn’t help to try to correct their inaccurate view of reality. Losing their rational thinking skills means they’ve lost the ability to compare their own version of reality with ours, and to analyze which view of reality is more likely, logical, or true. The result is that people who are experiencing dementia live in an altered reality and may believe that very illogical things are true, including dreams.
