Two new vision tests can help doctors see Alzheimer's coming



Prediction of Alzheimer's disease has proved as difficult and difficult as healing it – but new research has provided promising ways for early detection.

Now two independent research projects have found clues in the eyes of Alzheimer's test subjects at an early stage.

First, subjects conducted by a research team led by Thom Wilcockson of the School of Sports, Exercise and Health Sciences at Loughborough University include measuring eye movements when subjects try to ignore distractions on the screen.

Second, scientists from the University of California, San Diego School of Medicine suggest that the speed at which a student dilates while focusing on a cognitive test provides an early clue to Alzheimer's.

A matter of focus

Loughborough researchers argue that the ability to focus can predict which patients with mild cognitive impairment will develop Alzheimer's disease. Findings published aging magazine.

The ability of the mind, not only to focus or remember the facts, but to ignore the stimuli, seems to be a powerful predictor of Alzheimer's.

Mild cognitive impairment (MCI) is a strong predictor of Alzheimer's. Some studies have shown that 46% of people over 65 years of age with MCI will develop fully swollen dementia in three years compared to only 3% of other people in the same age group.

Test subjects were instructed to refrain from looking at disturbing objects on the computer. Scientists then calculated the number of people ignoring these random seeming points and gave a score strongly associated with the emergence of Alzheimer's.

The result of the team: The ability of reason, not only to focus or remember the facts, but also to disregard stimuli seem to be a strong predictor of Alzheimer's.

Don't look at students

Meanwhile, William Kremen & # 39; s UCSD team on the observation of tau proteins published their latest findings on student expansion. Aging Neurobiology.

Tau proteins, which contain plaques and folds in Alzheimer's first affected brains, damage a region of the brain called locus coeruleus, which controls brain dilatation. The researchers focused on the fact that tau formation affecting the eyes can be determined well before Alzheimer's memory affects.

The UCSD team tested the student's response to 1,119 men aged 56-66 and compared their performance with Alzheimer's family history.

Conclusion: Men whose relatives developed Alzheimer's had slower student responses, suggesting another way eye tests could diagnose Alzheimer's early.

A growing set of diagnostic tools

These new reports are some of the latest developments that could strengthen Alzheimer's early warning systems.

The quest for the hero of the sea, a video game designed to detect these memory gaps, has been used by more than 4 million people. According to their creators, the game produces the same amount of data in a two-minute game, which will take five hours for scientists to gather in a lab.

A recent study by Eli Lilly & Co., Apple and Evidation Health found that the way someone uses their mobile device – whether it's an iPhone, a tablet, or wearable – can be used to predict signs of dementia.

In the meantime, a new blood test can identify the markers of Alzheimer's disease for up to twenty years before the symptoms appear in the first study from the University of Washington School of Medicine. The blood test measures amyloid beta levels, a protein fragment that forms in the brain and creates plaques and nodes characteristic of Alzheimer's.
