Warning signs of dementia revealed through our eyes #
A study carried out by English researchers suggests that visual disturbances could indicate a risk of dementia up to 12 years before its formal diagnosis, particularly for diseases such as Alzheimer’s.
Scientists observed that changes in the ability to perceive complex visual patterns, such as a triangle forming among a field of moving dots, were notable in individuals who would later develop dementia. This finding suggests that regular eye exams could play a crucial role in early detection of the disease.
The cerebral and visual mechanisms involved #
The results of this research shed light on the relationship between vision problems and the early stages of dementia. Amyloid plaques, often associated with Alzheimer’s, initially affect the parts of the brain responsible for vision. This early deterioration may manifest as difficulty recognizing specific shapes or colors, particularly in blue-green spectrums.
It is crucial to understand that these visual symptoms are not simple eye problems, but warning signals sent by the brain. This highlights the importance of not ignoring such symptoms and consulting a specialist who can perform in-depth tests to assess dementia risk.
Preventing dementia through daily activities #
In addition to eye exams, the study found that certain activities could help reduce the risk of developing dementia. Reading and watching television, for example, are activities that stimulate not only vision but also cognitive abilities.
People who regularly engage in these activities tend to have better memory and a reduced risk of dementia. This suggests that healthy lifestyle habits, including regular mental stimulation, could be beneficial for maintaining good brain health in the long term.

| Indicator | Description |
|---|---|
| 👁️ Visual problems | Difficulty perceiving complex patterns and specific colors |
| 🧠 Amyloid plaques | Affect visual areas of the brain first, then memory |
| 📚 Reading and TV | Activities that boost memory and reduce the risk of dementia |
This study shows us that seemingly simple aspects of our daily lives, such as our ability to see and perceive the world, are intimately linked to our brain health. By paying attention to these details, we can aspire to a healthier future and, potentially, extend our quality of life by preventing devastating diseases like dementia.
