Why your eyes might be the key to early Alzheimer's diagnosis
Could a trip to the ophthalmologist also be a diagnosis of Alzheimer's disease? Recent research indicates that small blood vessels in the back of the eye can reveal the progression of the disease in your brain, and a general eye scan can detect these changes before much damage has been done. Make sure you know these 10 early signs of Alzheimer's.
Two recent studies published by the American Academy of Ophthalmology suggest that imaging, known as optical coherence tomography angiography (OCTA), may help physicians identify signs of Alzheimer's disease in the small veins in the fundus. Although neurologists can use brain scans to detect the damage of Alzheimer's. med. Ygal Rotenstreich, ophthalmologist at the Goldschleger Eye Institute of Sheba Medical Center in Israel and one of the leading researchers in a study, said in a press release at this time illness is well beyond a treatable stage. "The goal of the research was to find a precise, inexpensive test that can detect Alzheimer's before too much damage has occurred. Take a look at 6 newer breakthroughs in Alzheimer's research.

In the first study, Duke University researchers examined OCTA to examine the retina of Alzheimer's disease patients and compared it to those of people with mild cognitive impairment and healthy people. The theory is that the blood vessels in the fundus can reflect changes in the brain. The researchers found that members of the Alzheimer's group have lost small retinal blood vessels in the back of the eye. They also found that a specific layer of the retina was thinner.
In the study of Dr. med. The researchers conducted OCTA and brain scans on more than 400 people who had a family history of Alzheimer's – but had not yet developed any symptoms. They compared the pictures with those of people without a family history of the disease. As in the first study, Dr. Rotenstreich noted that the inner layer of the retina was thinner in people with Alzheimer's history. The study also found that the hippocampus, an area of the brain first affected by the disease, was already beginning to shrink. Learn more about the stages of Alzheimer's disease.
While researchers are still looking for effective ways to treat Alzheimer's, the existing instruments now work better when the disease is at an earlier stage. "We need a treatment sooner," Dr. Red String. "These patients are at such a high risk." Stop believing these 15 myths about Alzheimer's.

Eating habits to protect your brain from Alzheimer's
Fill up less calories
Start your meals with vegetarian-packed salads or soups, or use small plates to get your brain to make your meals look bigger than they actually are. As you reduce your calories, you can lose pounds, which can help stop other risks of Alzheimer's disease, such as sleep apnea, high blood pressure, and diabetes. Reducing your daily caloric intake by 30 to 50 percent will also reduce metabolic rate and slow down the oxidation of the entire body, including the brain. It also lowers blood sugar and insulin levels.
Eat at least five servings of fruits and vegetables every day
Higher vegetable consumption was associated with a slower cognitive decline in 3,718 individuals aged 65 years and over who participated in the Chicago Health and Aging Project. The study participants completed meal protocols and agreed to periodically test their cognitive abilities for six years. All study participants were lower in cognitive testing at the end of the study than at baseline, but those who consumed more than four servings of vegetables daily showed a 40 percent lower performance drop than those serving less than one consumed daily. that you can recognize the 10 early signs of Alzheimer's that every adult should know.
Use spices generously
Herbs and spices add flavor to the food so you can reduce butter, oil and salt. Because they come from plants, many herbs and spices also contain antioxidants and offer many healing benefits, including Alzheimer's prevention. Various studies show that, for example, curcumin reduces the risk of cancer, arthritis, depression and Alzheimer's disease. Just a quarter teaspoon twice a day reduces fasting blood sugar in people with type 2 diabetes by up to 29 percent. This is important because type 2 diabetes can increase the risk of developing Alzheimer's disease.
Marinate meat before cooking
When fat, protein and sugar react with heat, certain harmful compounds form, known as Advanced Glycation End Products (AGEs). They are particularly high in bacon, sausages, processed meats and fried and grilled foods. It has been shown that consuming large amounts of AGEs causes harmful changes in the brain. However, there is a simple way to reduce your ALTER consumption: Make your food (especially meat) as moist as possible. By cooking, braising, poaching, or marinating meat and fish before grilling or grilling, you let the moisture penetrate their flesh, drastically reducing AGEs.
Eat cold-water fish once a week
Fish swimming in cold waters tend to develop a layer of fat to keep them warm. This type of fat, called omega-3 fatty acid, has been shown to reduce inflammation throughout the body when consumed by humans. In a study of 815 individuals who consumed fish at least once a week, the risk of Alzheimer's disease was reduced by 60 percent compared to people who had rarely or never eaten fish.
Snack on nuts and seeds
Not only are nuts and seeds rich in omega-3 fatty acids, they also provide a good dose of selenium and vitamin E, two other nutrients that can boost brain health. Walnuts can be a particularly effective source of edible brain protection. In addition to omega-3 fatty acids, walnuts are rich in antioxidants that have been shown to reduce Alzheimer's disease in mice. Avoid these 9 habits that can seriously increase your risk of dementia.
Drink several cups of tea a day
Black and green tea are rich in antioxidants called catechins, which can ward off oxidative damage throughout the body, including the brain. Green tea is also a rich source of epigallocatechin-3-gallate (EGCG), which has been shown to reduce beta-amyloid plaque and tau implications in mice. It has also been shown that tea lowers blood pressure and cholesterol levels.
Enjoy a coffee in the morning
Caffeine consumed too late can disturb your sleep. Coffee, which is drunk in the morning and possibly in the early afternoon, may reduce the risk depending on personal caffeine sensitivity. Coffee contains a chemical called eicosanoyl-5-hydroxytryptamide (EHT), which protects against Alzheimer's disease in studies in rats. The caffeine itself can also be protective: Mice developed fewer tau complications in their brain when their drinking water was infused with caffeine. In humans, Johns Hopkins researchers have shown that 200 milligrams of caffeine (the amount in a strong cup of coffee) can help us consolidate memories and make it easier to memorize new information. Do not miss these 15 other things that neurologists do to prevent Alzheimer's.
Eat dinner with dark chocolate, not chocolate cake
Most desserts are high in high blood sugar, and recent research has linked high blood sugar levels to oxidative damage and increased production of beta-amyloid protein plaque. However, chocolate can be an exception. Chocolate contains antioxidant chemicals called flavonoids, Protective substances are also present in many colorful fruits and vegetables. Baby boomers, who consumed chocolate-rich drinks twice a day for three months, also showed memory tests as several decades younger. In one part of the same study, tests showed that the chocolate drinks also seemed to improve blood flow to the hippocampi regions of the brain. Here are even more everyday habits that can reduce the risk of Alzheimer's.
