Tips for Living with Eye Issues Related to Alzheimer’s Disease | World Alzheimer’s Month

​According to the National Institute on Ageing, in the United States, over six million people are living with Alzheimer’s disease. The reason Alzheimer’s disease occurs is not completely known. Researchers believe it could be a combination of genetic factors and changes to the brain that occur over time.
​
The symptoms of Alzheimer’s include:

• Problems with memory
• Mood changes
• Trouble concentrating
• Impaired reasoning

Alzheimer’s disease often touches all areas of a person’s life. It can even affect their vision. October is World Alzheimer’s Month and is a good time to take a look at ways to cope with eye issues related to Alzheimer’s disease. 
​

What happens with vision? 

A few different eye issues may develop in people with Alzheimer’s. For example, the field of vision may narrow. In addition, the changes to the brain may cause difficulties interpreting the images a person sees. The part of the brain that handles visual cues may not interpret the information as it should. So, although the eyes may be healthy, vision may still be impaired. 

Alzheimer’s disease usually happens later in life in the 6th or 7th decade. During this time, older adults are at an increased risk of developing eye diseases, such as cataracts, glaucoma, and age-related macular degeneration. These eye conditions can also affect vision.

For some people, their vision problems are a combination of eye disease and issues associated with Alzheimer’s disease.

Tips for coping with vision changes

Problems with vision can worsen issues related to dementia. Vision problems may increase disorientation and cause more problems with mobility. Decreased vision can also affect one’s ability to learn new tasks and increase isolation.

Slowing down the progression of Alzheimer’s disease as much as possible can help a person maintain their vision. As Alzheimer’s progresses, problems with sight may also start and progress. Below are several ways to help someone cope. 

Get regular eye care: It is vital to have regular eye exams to detect any eye diseases that may occur. Remember, eye disease can occur in addition to Alzheimer’s. Regular eye appointments can help make sure glasses prescriptions are current.

Stand in front of someone when talking: Some people with dementia have a loss of side vision. A decrease in peripheral vision can make it difficult for someone with Alzheimer’s disease to understand who is talking to them unless the person is right in front of them.

Turn lights on gradually: The pupils of people that have Alzheimer’s may take longer to adjust to light changes. Consider turning the lights on gradually. For instance, use dimmers that you can adjust. Or, use a small table lamp before turning on a bright overhead light.  

Safety proof the environment: As vision decreases, it may increase a person’s risk of falling. Making a few changes to the environment may help. For instance, reduce clutter, improve lighting, and remove throw rugs that may lead to a fall.

Keep furniture in familiar places: Try to keep furniture and other household items in the same location to help individuals navigate their homes easier.

Seek support: Seek professional help for vision issues, such as working with an occupational therapist or a visual rehabilitation therapist.
