How Dementia Impacts Vision

Learn how dementia impacts vision and how to help older adults feel safe.

The intricate steps needed to enable us to see are mind-boggling. In the blink of an eye, our brains have the ability to take transmitted details on the environment all around us, translate that information based on input from other senses, experiences, and thoughts, and then build an understanding of that information to make us aware of what we are seeing.

It’s not surprising to learn that dementia impacts vision, and that individuals with dementia can encounter visual deficits and misperceptions, particularly in the aspects of:

  • Depth and/or color perception
  • Contrast
  • Motion recognition
  • Peripheral vision

Moreover, people who have Alzheimer’s disease can frequently experience a distorted sense of reality in the form of illusions. As an example, someone with Alzheimer’s disease could see a shadow on the floor, and confuse it for something innocent, such as the family pet, or a hazard, such as an intruder. Some other types of visual misperceptions in dementia can consist of:

  • Misjudging reflections in glass or mirrors for another person. This could lead to distress in believing someone else is present, or believing that a restroom mirror reflection means the washroom is currently occupied by another person.
  • Believing that images on television are real and taking place in the room.
  • Difficulty with sitting in a chair or on the toilet, being afraid of a fall.
  • Stress in overstimulating environments that causes confusion.
  • Reaching for objects that are not there, or missing the mark in trying to grab an item.
  • Troubles with self-feeding and drinking.

Below are some approaches to help clients:

  • Keep sufficient lighting through the entire home, and remove any particular items that cause stress or visual confusion when possible.
  • Incorporate contrasting colors anytime you can; for example, serve dark-colored soup in a light-colored bowl, or a fried egg on a brown plate.
  • Close blinds or curtains both at night and whenever the sun causes a glare.
  • Take advantage of adaptive tools such as remote controls and telephones with large buttons to help facilitate opportunities for independence.
