How Dementia Affects Vision
Dementia can considerably impact a person’s vision, creating fear and confusion. As a result, the individual starts to behave strangely. If you’ve noticed a senior with dementia acting this way then it’s highly likely that their condition has taken a toll on the way they see things.
Compassion Home Care, Inc. dba Zion Hands of Grace is a reputable provider of home care in Chattanooga, Tennessee that believes awareness of the way vision changes with dementia can help families better handle the disease.
So what exactly happens to a person’s vision when they have dementia?
- Reduced visual field.
Dementia causes the area surrounding you where you can see things to become smaller. Because of this narrower visual field, a person with dementia feels like he or she is walking around wearing binoculars. They sometimes even miss things that are right in front of them.
- Absence of peripheral vision.
Think about a horse wearing blinders. This is what people with dementia sometimes feel with the loss of their peripheral vision. They’re no longer able to see things that aren’t directly in front of them. Losing this part of one’s vision can be dangerous as it would easily cause them to trip on objects or bump into things that are right at their side.
- Blurred vision.
Blurring of the vision can happen when a person has dementia. Objects and faces become difficult to make out because your vision is less sharp than it was. You would even find reading and writing an immense difficulty at times.
- Pupils react slowly to light.
Moving from a dark room to one that is filled with light can be overwhelming for an individual who has dementia. This is because their pupils adjust very slowly to light changes.
- A huge issue with depth perception.
Late-stage dementia can make whatever a person sees much more complex for the brain to process. When dementia is this advanced, an individual is only able to see from one eye, making it difficult for them to judge space and distance. It can even make it hard for them to perceive the shape of an object. Again, this could make dementia patients vulnerable to slipping and falling over and even influence strange behavior and weird decisions.
Vision is just one area affected by dementia and it already sounds like family caregivers in for a lot of work. Keep in mind that caregiver burnout is not healthy and you should always make time for yourself and take a break. During these times you can rely on providers of respite care in Tennessee like Compassion Home Care, Inc. dba Zion Hands of Grace to care for your loved ones in your stead.
