The complex steps needed to enable us to see mind-boggling. In the blink of an eye, our brains can easily take transmitted specifics of the environment all around us, translate that information based on input from other senses, experiences, and thoughts, and then shape an understanding of the information to make us aware of what we’re seeing.
It is no surprise that those with Alzheimer’s disease can encounter visual deficits and misperceptions, particularly in the areas of:
The depth and color perception
Contrast
Motion detection
Peripheral vision
Moreover, individuals with dementia can frequently suffer from a distorted sense of reality in the form of illusions. For instance, an individual with dementia could see a shadow on the ground and mistake it for something harmless, such as the family dog, or a hazard, such as an intruder – which can pose a challenge for family caregivers. Some other examples of visual misperceptions in dementia include:
You are misjudging reflections in glass or mirrors for another individual. This could easily cause distress in believing another individual is there or believing that a washroom mirror reflection means the bathroom is currently occupied by someone else.
I believe that images on television are authentic and occur within the room.
Problems with sitting in a chair or on the toilet, being afraid of a fall.
Anxiety in overstimulating environments confuses.
It was reaching for objects that weren’t there or missing the mark in trying to grab an item.
Troubles with self-feeding and drinking.
Below are some ways to help when dementia affects vision:
Keep sufficient lighting throughout the entire home and remove any specific things that cause anxiety or visual confusion when possible.
When feasible, utilize contrasting colors, such as serving dark-colored soup in a light-colored bowl or a fried egg on a black plate. If possible, carry this concept to home furnishings, with darker furniture on a light carpet and differing paint colors on trim vs. walls.
Close blinds or curtains both at night and whenever the sun’s rays cause a glare.
Use adaptive tools such as remote controls and telephones with large buttons to provide the senior loved one with sufficient opportunities for independence.
Confirm your loved one has ongoing access to eye care and notify the ophthalmologist of the older adult’s dementia diagnosis.
