We often believe that the function of the eyes is only to see, but do you know that your eyes can also tell about the health of your brain. Recently, scientists have made such a shocking revelation that it can be known whether a person may suffer from a serious disease like dementia in the future or not and this signal comes directly from the eyes.

Dementia is a disease that gradually changes a person’s memory, thinking ability, daily activities and even his nature. This disease is not limited only to the elderly, but can affect anyone with time. Now scientists say that if some changes occurring in the eyes are identified in time, then the risk of dementia can be understood in advance and steps can be taken towards treatment.

What is dementia and how dangerous is it?

According to the National Institutes of Health, dementia is affecting millions of people around the world. In America alone, more than 60 lakh people are suffering from this disease and every year about 10 lakh people die due to complications related to dementia. Dementia is not a single disease, rather it is a group of many types of brain diseases, the most common of which is Alzheimer’s disease.

If you see these symptoms in the eyes then understand that dementia is going to happen.

Scientists have found that a very important part present at the back of the eyes, the retina, can give an early indication of the risk of dementia. The retina is the part of the eye that captures light and transmits it to the brain. The retina is like a bridge between the eye and the brain. According to experts, the optic nerve is directly connected to the central nervous system. Therefore, if the retina starts weakening or becoming thin, it may be a sign that changes are gradually starting in the brain.

What did the research reveal?
In a study published in the journal Frontiers in Aging Neuroscience, scientists conducted research on about 30,000 adults for about 10 years. During this, the eyes of the participants were examined with a technique called retinal optical coherence tomography (OCT). People who had thin retinas were found to be at higher risk of developing dementia. With every unit decrease in retinal thickness, the risk of dementia increases by 3 percent. The risk of frontotemporal dementia (FTD) was found to be 41 percent higher in people whose layer in the middle part of the retina was thin. In the follow-up done after 9 years, 148 people were diagnosed with Alzheimer’s and 8 people were diagnosed with FTD, which proved the research results correct.

Common symptoms of dementia

According to the National Institute on Aging and the NHS, the symptoms of dementia gradually increase, such as frequent forgetting of things, slow thinking and understanding, trouble finding words in conversation, difficulty in making decisions, sudden changes in mood, irritability or restlessness, difficulty in doing everyday tasks. If these symptoms persist for a long time, it is very important to immediately consult a doctor.

Can dementia be prevented?

There is no sure shot cure to completely prevent dementia, but its risk can be reduced by adopting some habits. Which includes healthy and balanced diet, daily exercise, activities that keep the brain active, adequate sleep, abstinence from smoking and alcohol, regular eye and health check-ups.

Parkinson disease is a neurological disease. Now a big change is going to come in its identity and treatment. Recently in the research published in Nature Aging, it has been claimed that a new RNA-based blood test can be detected before the beginning of simples such as the problem of trembling or walking in hand and legs. That is, it will be easy for patients to diagnose on the initial stage itself.

How does blood test work?

This test is based on small fragments of TRNA (Transfer RNA). Earlier TRNA was linked to the process of making only protein, but now research found that its fragments can also give information about the disease.

Researchers get two special biomarkers

• Nuclear TRNA fragments, which are more in Parkinson patients.
• Mitochondrial TRNA Fragment, which is low in patients.

From the proportion of these two, it was found that the person is normal, on the initial stage or on the advance stage. The accuracy of this test came out 86 percent in a big study.

Why is this discovery special?

So far, Parkinson is detected only when I come to the Simpams. But this blood test:

• This is much cheaper than the rest of the treatments
• This will reveal the disease rapidly
• Apart from this, only blood samples (minimly-invasive) test process.

This test can be effective for those who have a high risk of Parkinson, eg, erasure to end genro disease, REM Sleep Disorder or Smell.

FDA approval and future

There will be more trials on this test right now. But recently FDA has approved the blood test for Alzheimer’s Disease, which is expected that the Parkinson test may also get approval quickly. In the future, this test can be useful not only to diagnose but also to track disease progress and to see the effect of treatment. If all goes well then this test routine can become a part of health checkup. Researchers believe that this test will be tested on a large scale in the coming time. Also, it will be made more accurate by adding more biomarkers to it. It can become a powerful diagnostic tool in combination with future genetic testing and brain imaging.

For the last two decades, the National Football League has surrounded a degenerative brain disease. Its continuous mention in a billion dollar cases, Congress hearing, a top film and anxia’s obwright have now infiltrated the most viilent ways in this favorite sports of America. A Casino Employee from Las Vegas shot four people in Skyscrapper in New York City, who is the headquarters of NFL. He also left a note, in which he blamed the league for his mental health problems. He told the time of his high school football player.

When does this disease detect?

27 -year -old Shane Tamura wrote in a three -page note found in his wallet that he has a chronic traumatic encephalopathy, whose diagnosis can only occur after death. At the same time, he requests my brain from those who found them. NFL’s Against Complaints also included the claim that the league hid the damage from CTE and football and gave priority to the players before the safety of the players. While repeating a scary trend in NFL players suicide, he shot himself in a chest, and kept his brain safe for post -mortem. This can confirm whether his common diagnosis was correct or not.

Connection with these injuries

CTE, a degenerative brain disease, which is linked to the Normal Constion to be held in Military War and Contact Sports and another head injuries. Its diagnosis has been done in more than 100 X NFL players and has become a threat for the US’s most powerful professional sports league. Due to its Dangers, some states have considered banning young football. The leagues at most levels have been motivated to limit the contact exercise in practice and have made many types of trauma protocols and other rules to remove the most valent aspects from this tuff game.

What is CTE after all?

Chronic tramatic encephalopathy (CTE) can affect the brain areas that control behavior and emotions. This can lead to memory loss, depression, sudden change in mood and other cognitive and behavioral problems. However, researchers say that these symposes can also be linked to other diseases. Experts say that Simpams can be seen many years or decades after the last brain trauma. Evidence of this disease has been found not only in people with long professional careers, but also in high school athletes.

Research between CTE and football

A study conducted by CET Center at Boston University in 2017 found that 111 NFL brains were examined, 110 were CTE present at one level in 110. In September 2024, a study made by Football Players Health Study at Harvard University revealed that about one third of the 2,000 former NFL players samples believed that they had CTE.

Understand the symptoms of CTE in detail

Chronic traumatic encephalopathy is a brain disease that develops symptoms over time and their severity may vary from every human being. These sympoons often begin to appear several years or decades after the last head injury or the end of sports activities. Its main symptoms include changes in mood, behavioral changes and changes in mental function. In addition, muscle problems such as difficulty walking or involuntary acts can also be seen. These symptoms can also be found from other diseases. Therefore, the advice of experts is necessary for the right diagnosis.
