25 Signs and Symptoms of Alzheimer's Disease
Trouble with visual or spatial relationships
One symptom of dementia is vision problems that are different from typical age-related problems such as cataracts.
People with AD tend to have difficulty reading, judging distances, and determining color or contrast as time goes on.
In terms of perception, they may look in a mirror and think someone else is in the room instead of realizing they are looking at a reflection.
Dementia can also cause changes in visual and spatial abilities. They can find it tough to distinguish food from the plate it’s on, for instance.
