Neurodegenerative diseases such as Alzheimer’s or dementia are more common in the elderly. The World Health Organization (WHO) It is estimated that 5% to 8% of people over the age of 60 have dementia. So there are several factors that are questionable for science. One of the most important factors is genetics.

For the above percentage, University of California Research Group, San Diego (UCSD) Has developed a statement Who can identify basic information about human neurological functions by looking at the size of a goog.

According to one of the largest studies to date, up to 75 genes associated with an increased risk of dementia, including 42 previously unwritten genes, have been identified by analyzing the genomes of 100,000 and 600,000 healthy people with Alzheimer’s disease.

In this sense, it is believed that the immune system has some connection with its appearance, as it can be caused by the “overly aggressive” response of the brain’s immune cells, the so-called immune system. Microglia.

In addition, other investigations have found that there is a The link between depression and Alzheimer’s disease Whereas in the most severe cases of the first case the memory decays faster.

Neurodegenerative diseases can be detected by application

Contribution Technology There are numerous improvements in the quality of life of people with neurodegenerative diseases. In this particular case, By self-diagnosis it is really simple.

“While there is still a lot of work to be done, I’m excited about the potential of using this technology to bring neurological screening laboratories home and out,” he explains. Release Colin Barry, The main author of the article.

Therefore, students’ changes are measured by the so-called method Student response test, But currently it requires specialized and expensive equipment, so it is impossible to get out of the clinic.

The app uses A’s near-infrared camera Smartphone To detect a human gut. thus, The app can calculate height with less than a millimeter accuracy compared to a student meter.

Besides, Researchers have made it really accessible to people of all ages, Such as older people who are less familiar with new technologies.

This tool is currently in development to ensure accessibility for everyone with a simple gesture Mobile devices.

How Alzheimer’s disease affects the brain

Scientists continue to understand the complex changes in the brain during Alzheimer’s disease. It is likely that changes in the brain may begin Ten years or more before symptoms appear.

Toxic changes occur in the brain at this extremely early stage of Alzheimer’s disease, including abnormal accumulation of proteins that form amyloid plaques and tau.

Neurons that were previously healthy stop working, They lose contact with other neurons and die. It is believed that many other complex changes in the brain also play a role in Alzheimer’s disease.

It looks like the damage is happening at first Hippocampus and entorhinal cortex The parts of the brain that are essential for memory formation. As more neurons die, other parts of the brain are damaged and begin to shrink.

In the last stage of Alzheimer’s disease, The lesion is extensive and the brain tissue is significantly reduced.
