Title: Pupil Movements Could Help Predict Later Dementia, Researchers Find
By Judith Braun
September 19, 2023, 3:49 p.m – Researchers at the University of San Diego have discovered a remarkable link between pupil movements and the early detection of Alzheimer’s disease, according to a study published in the journal Neurobiology of Aging. The findings suggest that changes in the brain of Alzheimer’s patients influence pupil movements, making it possible to predict the onset of the disease even before symptoms appear.
Alzheimer’s disease is the most common form of dementia, and while there is currently no cure, its progression can be slowed down significantly if detected early. It is crucial to identify the signs of the illness as soon as possible. Researchers have already found various indicators, such as sleep-related symptoms that can emerge years before the onset of dementia. Additionally, a revolutionary blood test for diagnosing dementia is being developed for the future. Now, scientists have discovered that the eyes may offer another way to predict the disease.
The study conducted by the University of San Diego focused on observing pupil movements in conjunction with cognitive testing. Pupillary responses are controlled by the locus coeruleus in the brainstem, which is responsible for cognitive functions. The protein tau, strongly linked to perception, forms clumps in Alzheimer’s patients. During cognitive tasks, the locus coeruleus alters the pupil diameter. The study found that individuals with clumped tau and mild cognitive impairment exhibited greater pupil dilation and higher cognitive effort.
These findings suggest that tracking pupil movements could serve as a screening method for the early detection of Alzheimer’s risks and facilitate early treatment. Detecting the disease at an early stage is crucial because healthy lifestyle choices, physical activity, memory training, and medication can significantly slow down its progression.
The researchers hope that their study will lead to the development of a simple and non-invasive method for identifying individuals at a higher risk of developing Alzheimer’s. By monitoring pupil movements, doctors may be able to intervene before irreversible damage occurs in the brain.
It is important to note that this research is still in its early stages and requires further validation. However, it offers promising possibilities for early detection and intervention in the fight against Alzheimer’s disease.
In conclusion, this study conducted by the University of San Diego suggests that pupil movements may provide valuable insights into the early detection of Alzheimer’s disease. By observing changes in pupil dilation and cognitive effort, researchers were able to identify an increased genetic risk for the disease long before symptoms appeared. While more research is needed, this discovery could potentially revolutionize the diagnosis and treatment of dementia in the future.
