This change with your eyes can predict dementia, says a new study

Knowing what to search can lead to early diagnosis and better treatment options.


In the first stages of dementia, its symptomscan be difficult to spot- But knowing that you (or a loved one) is at high risk can help put these subtle changes in the context. This is important because early diagnosis allows previous intervention and treatment.

Now, a new study shares a way for eye health changes could help predict the future cognitive decline. He indicates that a particular change, that your doctor can notice during an examination of the sight, could serve as "non -invasive ocular biomarker" for future dementia. Read the rest to find out which change with your eyes could help predict dementia and what other eye conditions are linked to your cognitive health.

Alzheimer's disease and other forms of dementia can affect health and vision of the eyes.

Alzheimer's (AD) disease - a neurodegenerative disease caused by an abnormal accumulation of amyloid and tau proteins in the brain - is the most common cause of dementia in the elderly. Alzheimer's symptoms often include loss of memory, difficulties in thinking,Behavior and mood changes, and more.

In addition to these common symptoms, people with Alzheimer's can also undergo changes in their vision, such as poor peripheral vision, difficulties with object recognition, poor discrimination of colors and a perception of lowered depth. This link prompted researchers to explore the link between eye health and dementia.

"The relation betweenBrain fabric and eye fabric is an intense area of ​​interest in ophthalmologists and neurologists, "explains the American Academy of Ophthalmology." Research shows that brain diseases and conditions can also affect the eyes because the optic nerve and the retina are in fact cerebral tissues that extend outside the cerebral case. Alzheimer's disease and dementia, which are caused by damage to brain cells, seem to have effects on the retina. ""

This change with your eyes can help predict dementia.

According to a study in 2022 published in the journalJama ophthalmology, a particular ocular change could offer an index on your future risk of dementia. The study, which took place in South Korea, examined the link betweenRetinal layer thickness And the future cognitive decline of a cohort of 430 individuals over 60 years of age. They concluded that the thickness of the layer of macular retinal nerve fibers (RNFL) is associated with a future cognitive decline in the elderly.

"We propose that a thinner macular RNFL can predict a drop in cognitive performance," said the study. "Overall, the macular thickness of the RNFL can be considered as a non -invasive ocular biomarker to assess changes in cognitive function in patients."

The thinner the RNFL, the greater the drop in cognitive scores, revealed that the study.

The authors of the study observed a correlation between the extent of the cognitive decline and the degree of macular thinning of the RNFL. "A greater drop in cognitive scores and a higher prevalence of cognitive impairment and Alzheimer's disease have been observed for participants with a thickness of total macular RNFL below the lowest quartile cut -off value compared to those with a RNFL thickness above the lowest quartile cut value, "they wrote.AE0FCC31AE342FD3A1346EBB1F342FCB

Although these changes are likely to go unnoticed by the person who lives them, an eye specialist can see these changes during an examination of sight.

These other eye conditions are linked to your cognitive health.

Several other studies have worked to shed light on the links between ocular health andbrain health. Until now, the evidence suggests that people with macular degeneration, glaucoma and diabetic retinopathy are at a significantly increased risk of developing dementia at the bottom of the road.

In fact, a 2018 study of the University of Washington and the Permanent Kaiser Washington Health Institute revealed that the subjects which had one or more of these eye conditions were in a40 to 50% higher risk Alzheimer's disease, compared to others who have not done so. Although all those who have eye problems do not develop a neurodegenerative condition, the results highlight the importance of sight exams, which the American Academy of Ophthalmology recommends for all those who start at the age of 40.

Talk to your doctor or ophthalmologist if you notice changes in your vision, or if you have questions about how your eye health can tell you other aspects of your general health.
