Dementia has the ability to rob patients of their routines through memory loss. Much worse, it can make precious memories feel blurry or even nonexistent. In recent years, research has drawn connections between dementia and cataracts. Is there a link between the two conditions - and could cataract surgery have an impact on dementia?
While not a single disease, dementia refers to a collection of symptoms relating to worsening memory and cognition. This could be shown through memory loss, forgetfulness, poor deductive reasoning, and reduced socialization. Some of the most common causes of dementia include Alzheimer’s disease, Parkinson’s disease, and severe head trauma.
Your eyesight is extremely vital for your cognitive functions. Due to most activities and day-to-day actions being visual in nature, reduced vision could lower mental stimulation that comes from performing tasks like cleaning, driving, or reading. Based on this premise, conditions like cataracts (or other eye conditions like diabetic retinopathy, glaucoma, etc.) that negatively affect eyesight could also impair cognitive abilities and recalling information.
The University of Washington shared research in 2022 regarding cataract surgery and dementia. Their research suggests by removing cataracts to clear up cloudy vision, patients can resume their normal activities and continue to be visually and mentally stimulated – thus lessening dementia risk. The takeaway from this is that if patients can have their vision restored, the chances of developing dementia may lower in the long run. Dr. Veena Rao, a CEENTA cataract surgeon at our Matthews and Monroe offices, provided her take on the research. “The results of this recent research help those of us with family and friends with dementia think of vision in a new light. If we now feel improved vision can help keep people thinking sharply and perhaps reduce dementia risk, cataract surgery may gain importance in people dealing with the condition."
Although this is a single study and these results would need to be replicated in additional studies, the data is promising.
