Are you always doing it before going? Better stop. The widespread habit increases the risk of dementia

Blue light from the screens of telephone, computers and other devices disturbs the production of melatonin, a hormone regulating sleep, and also stimulates neurons. When we also stare at the phone during the day, a decrease in focus and concentration must also be added to negative effects. – The abuse of screen devices, especially just before bedtime, also affects the very course of sleep by disturbing the work of these neurons that are important for processes when the brain sleeps – Dr. Wojciech Glac, a neurobiologist from the University of Gdańsk, explained in an interview with event.interia.pl.

Consequently, the brain does not regenerate properly, He is not able to fully clean himself of toxins, including beta-amyloid, whose accumulation was observed in patients with Alzheimer’s disease. – So this can not only lead to being “sleepy”, but also problems with attention, memory and decision making – he emphasized.

Does excessive use of the phone cause dementia? Scientists warn

As in 2019, it was demonstrated in a study published in the International Journal of Mental Health and Addiction “, constantly staring at the phone screen, also before bedtime, in people between 18 and 25 years of age, it leads to the disappearance of the cerebral cortex, responsible, among others for remembering. In 2021 and 2022, “Journal of Integrative Neuroscience”, in turn, published several studies on “digital dementia”. Conclusions? The abuse of the phone and screens changes the volume of gray and white in the brain, impairs the process of creating memories and learning, at further stages of development leads to accelerated neurodegeneration, and consequently – dementia. It also increases the risk of cognitive, emotional and behavioral disorders in young people.

Evidence suggests that some of the symptoms are similar to those observed in adults with symptoms of mild cognitive impairment (MCI) in the early stages of dementia

– scientists alert in the “Journal of Integrative Neuroscience”. These include For problems with:

• concentration,
• orientation,
• acquiring new memories and recalling memories (reverse amnesia),
• social functioning.

We also recommend:

We hypothesize that excessive exposure to screens in critical periods of the development of the generation with will lead to mild cognitive disorders in early and average adulthood and will cause a significant increase in the indicators of early occurrence of dementia in later adulthood

– they sum up. Researchers predict that between 2060 and 2100 there will be a clear increase in the indicators of Dementia and Alzheimer’s disease.

What increases the risk of dementia? Not just phones

Among the factors that increase the risk of dementia, including Alzheimer, scientists indicate not only staring at the phone. Researchers from universities in British Exeter and Dutch Maastricht analyzed 350,000. people under 65, whose data was found in the UK Biobank database. They managed to discover what could affect the predisposition to early dementia. The conclusions were published in “Jama Neurology”. As Medonet.pl calculates, among the dozens of factors indicated by scientists, the most important are, among others Lower education and socio-economic status, vitamin D deficiency, hearing damage, depression, social insulation, stroke, diabetes and smoking.
