The Eye-Opening Link Between Alzheimer’s and Vision

Alzheimer’s and vision
Discover three ways Alzheimer’s and vision are linked to better help someone you love.

What’s the first thing that comes to mind when you think of Alzheimer’s disease? Perhaps it’s memory problems, or confusion and disorientation. One particular area that gets less attention, however, is the link between Alzheimer’s and vision changes. If you’re caring for someone with dementia, understanding these changes is key to understanding why certain behaviors are occurring and how to best help the person manage them.

There are three common vision problems to watch for:

  • Narrowing of the field of vision. Some degree of peripheral vision change is a normal part of growing older. Yet for someone with dementia, the change can be quite dramatic. Imagine trying to go through your daily activities while looking through a pair of binoculars. This gives you some perspective into how someone with dementia may be seeing the world, with perhaps only a 12” visual range.
  • Decreasing visual input. In the later stages of dementia the brain may be unable to process information being received from both eyes. When this happens, the senior begins to see with only one eye. This makes it difficult to discern whether something is 2- or 3-dimensional, making a pattern on the carpet appear to be something that may cause a tripping hazard. It can also make it extremely hard to judge the height of a chair and to sit down safely.
  • Changing depth perception. If you’ve ever watched someone with dementia grasping at something that isn’t there, you may have assumed the person was having hallucinations. While this may be the case, there may be another root cause: the loss of depth perception. Imagine trying to pick up an object that appears to be several inches in front of you, while in reality it’s several feet away, and you’ll have a better understanding of what the person is experiencing.
