This unusual symptom could be an unexpected indication of Alzheimer's

Scientists have highlighted a little known symptom of Alzheimer's disease that could help provide an earlier diagnosis in patients: it is the loss of smell.Find out the details of this research.

Scientists claim that a particular symptom could be an indication of Alzheimer's

Although it is thought that the initial damage to the brain of dementia occurs until 20 years before that symptoms appear , there is currently no evidence to confirm whether this is true or not.

However, now, scientists at McGill University (Quebec) believe they have found a possible link between loss of smell with early indication of the disease.

To test the theory in 300 participants who were at high risk of developing Alzheimer's disease because they had a father who suffered from her, each of these people was pi He gave me a multiple choice test that consisted of the classic scratch and smell games.

While everyone was asked to identify strong perfumes such as chewing gum, gasoline and lemon, 100 of them were also offered to have regular lumbar punctures to measure the disease-related proteins in their spinal fluid.

The researchers found that those who had the most difficulty identifying odors were also the ones who had more biological indications of Alzheimer's disease.

Loss of smell could be an unexpected sign of Alzheimer's

Marie-Elyse Lafaille-Magnan, author of the study, explained that this is the first time someone has been able to clearly show that the loss of the ability to identify odors correlates with biological markers that indicate the progression of the disease.

Also, it is necessary that for more than 30 years , scientists have been exploring the connection between loss of memory and the difficulty that patients may experience in the identification of different odors.

In her opinion as an expert, this makes sense because it is known that the olfactory bulb (involved with the sense of smell) and the cortex Entorhinal (involved with memory and the name of odors) are among the first brain structures that are first affected by the disease.

Although there is currently no treatment for Alzheimer's disease, experts say this odor test could be used to follow the disease before other symptoms appear and even to reduce the symptoms once they begin.

This unusual symptom could be an unexpected indication of Alzheimer's

Dr.John Breitner, director of the Center for Studies on Alzheimer's Disease Prevention at the University of McGill said that if you can delay the onset of symptoms for at least five years, it is possible to reduce the prevalence and severity of these symptoms by more than 50 percent.

Although researchers are hopeful, they recognize that it is still necessary to perform many more tests in this direction and that, for now, smell alone should not be used to diagnose the disease.

What do you think of this discovery about this indication of Alzheimer's? Do you think it will help improve conditions and the future of those who suffer?

What does a volcanic lightning sound like? It has been registered and it is not as we thought!

As we have said on more than one occasion, nature often surprises us in the most terrifying way that it knows.One of those ways is, without a doubt, the eruptions of some volcanoes, one of the events more impressive and fearsome that our planet can offer us .The eruption of a volcano is terrible, suffocating, noisy and also usually covers the entire terrain around a dense and thick fog accompanied by ash that can even last several weeks They can also be accompanied by some volcanic lightning , which can add a few electric fireworks and a great deal of noise to a whole spectacle, in itself ostentatious. Catching a volcanic lightning Scientists, to date, even knowing their existence, haven't h They had never heard a volcanic lightning due to the volcano's own thunder, but finally, in March 2018, the research team led by Matthew Haney of the US Geological Survey managed to register a authentic and terrifying volcanic thunder .Although it is something that is scientific...

A black hole will be photographed in 2017

2017 will be a year of challenges for astronomy, and in particular for the study of our solar system and the galaxy it is in.With some luck it could be the year that we managed to have the first photograph of a black hole Thanks to an international project, the Event Horizon Telescope . A black hole will be photographed in 2017 We will tell you a story that could reach a climax in 2017, but which began in 1971, when Martin Rees and Donald Lynden-Bell proposed the hypothesis that in the center of the Milky Way , our galaxy, there should be a supermassive black hole, which they named as Sagittarius A * , to differentiate it from the rest of the central sector, known as Sagittarius A, and to indicate that something very special was happening there. Supermassive black holes are usually found in the center of galaxies and there is still no cons among astrophysicists about how they originate, but they could play a fundamental role in the stability of elliptical and spiral galax...

8 countries that do not spend on army

Thinking about a country without an army sounds, for those of us who believe that war is not a passable road, like a beautiful melody, but is it feasible to happen? Are there countries that do not have armies, or that do not spend on military matters? If there are any, but not always by pacifist conviction.Take a look at this list so you know which countries lack army. 8 countries that do not spend on army The expense that most countries make in their army is sometimes obscene.War conflicts across the planet have generated Strangely high profits for companies engaged in arms production.It is natural, thus, that war be promoted at all levels, so that each independent state of the world invests in maintaining military forces and armies, with increasingly sophisticated weapons and all the latest generation elements. The end of the Cold War, in the late 1980s, halted world military spending, but in 2000, and especially after the attack on the Twin Towers in New York, this expense ...

The debt of sleep acquired every day should be targeted The study was I performed with 522 volunteers who suffered from type 2 diabetes.All of them had a blood test and all their body measurements were taken.During the 6 months that the first part of the experiment lasted the participants had to write diaries where they collected the dat The dream debt they contracted each week, that is, the time they had left to sleep.
