Spain has developed the video game The Mind Guardian, in collaboration with Samsung, for the early detection of neurodegenerative diseases, such as Alzheimer’s, with an effectiveness of 97 %.

The announcement was made by Samsung. And although The Mind Guardian is not intended to replace clinical diagnosis, it can help reduce the detection time for these diseases.

The video game consists of an “innovative application based on artificial intelligence that allows the assessment of cognitive performance in people over 55 years of age,” developed by Samsung Iberia in collaboration with the University of Vigo and the Galicia Sur Health Research Institute.

It is supported by the Spanish Society of Neurology and the Spanish Society of Psychiatry and Mental Health. It can be used to assess memory independently of an Android tablet. Its gamified design is user-friendly; it “reduces the anxiety associated with traditional medical tests and makes large-scale cognitive screening accessible.” Those interested can download the app from the Google Play Store.

Among the items included are challenges such as “remembering objects in a virtual city, matching images, or following movements on the screen. These tasks have been validated in studies with more than 150 users in day centers and senior citizen associations, achieving 97 % accuracy in detecting signs of cognitive decline.”

A team of scientists from China, the United States and Spain conducted a study, according to which poor sleep quality or difficulty in achieving paradoxical sleep could be an early sign of Alzheimer’s disease.

According to the team of scientists, there is a relationship “between sleep quality, memory formation, cognitive thinking and the risk of dementia.”

In the study, they analyzed the relationship between lack of sleep in patients with dementia, “Alzheimer’s and the biomarkers of said disease, even in its preclinical phases” in 128 adults with an average age of almost 71.

The participants remained overnight in a sleep clinic for sleep monitoring. Of the sample, “64 had been diagnosed with Alzheimer’s and 41 had mild cognitive impairment.” One group reached the REM phase in less than 98.2 minutes, while the rest took more than 192.7 minutes.

According to the scientists, elderly people with functional problems, combined with genetic risk, have a high probability of suffering from Alzheimer’s, due to their lower production of a protein called brain-derived neurotrophic factor, which favors the survival of neurons and helps the brain to learn.

The damage can manifest itself in an increase in “the stress hormone, cortisol. This can damage the brain’s hippocampus, a critical structure for memory consolidation.”

The specialists recommend improving the healthy sleep cycle through healthy lifestyle habits that help “prevent REM sleep delays, favor memory formation and, ultimately, reduce the risk of dementia.”
