First, everyday, familiar tasks will take longer than before to get them done, and eventually they will become harder to complete. The person will have trouble finishing them, getting distracted and confused in the middle of the process. Common activities like cooking a specific, favorite recipe or going to a certain location will also become difficult and challenging over time. This person also will struggle to learn new things and to adapt to new routines. This sign is an obvious symptom of early dementia, which should be your exclamation point if you have experienced this kind of everyday struggle.
