Here’s What Suicidal Thoughts Do To The Brain

First study to find these changes in the brains of depressed people experiencing suicidal thoughts. People experiencing suicidal thoughts have a certain type of inflammation in their brain, new research finds. Microglial cells activate as part of the body’s inflammatory response. The researchers found that these immune cells were more active in depressed people who were also having suicidal thoughts. The study suggests that neuroinflammation could play an important role in suicidal thoughts and behaviour. It may also offer another route to treat this type of depression: through the use

How Dementia Can Be Prevented For One-In-Three

There are 9 risk factors for dementia, which can all be reduced. One-in-three cases of dementia is a result of manageable lifestyle factors, a new report from 24 international experts concludes. There are nine risk factors identified by dementia experts: low levels of education, midlife hearing loss, physical inactivity, high blood pressure (hypertension), type 2 diabetes, obesity, smoking, depression, and social isolation. These risk factors account for 35% of dementia cases. In other words: changing or managing these factors will help fight off dementia. Addressing high blood pressure, obesity and

When These Muscles Are Fitter Your Brain Is Also Fitter

The brains and bodies of identical twins were compared over ten years. Stronger leg muscles are linked to better brain ageing, a new study finds. It’s the first time a connection has been found between power in the lower limbs and healthy ageing in normal people. The study suggests that increasing levels of simple exercises like walking or even standing for longer may lead to healthy cognitive ageing. The study followed 324 identical female twins over a ten-year period. Fitness and lifestyle habits were measured by researchers. They also gave

Insomnia Is NOT Just “All In Your Head”, Genetic Study Finds

Insomnia is the most common complaint people have about their health. Insomnia is not just “all in your head”, neuroscientists have found. For the first time, seven risk genes have been identified for insomnia. This could be the first step in understanding the biological causes of insomnia. It helps to show that insomnia is not — as is sometimes claimed — just a psychological condition. Professor Van Someren, one of the study’s authors, said: “As compared to the severity, prevalence and risks of insomnia, only few studies targeted its causes.

The Very Best Learning Method Is Not Taught To Students Or Teachers

The Very Best Learning Method Is Not Taught To Students Or Teachers

The one learning technique which works best is the one that students use the least. Spreading out learning over time is one of the most effective strategies. So-called ‘distributed practice’ means breaking up learning into short sessions. People learn better when they learn in these short sessions spread over a long period of time. The reverse — cramming in a short space of time — doesn’t work that well. Despite this, distributed practice is very infrequently used by students and may not be highlighted as a top strategy to them

The Best Exercise To Improve Brain Function

The Best Exercise To Improve Brain Function

With age people’s memory and thinking naturally slows down — but this process can be held in check. Lifting weights is one of the best ways of protecting brain function, research finds. The study found that increased muscle strength improved brain function in people with Mild Cognitive Impairment. LIfting weights was more effective than doing brain training exercises. Dr Yorgi Mavros, the study’s first author, said: “What we found in this follow up study is that the improvement in cognition function was related to their muscle strength gains. The stronger

Depression Reduced By This Ancient Method

Depression Reduced By This Ancient Method

People in the study were suffering from a major depressive disorder. Yoga and deep breathing classes twice a week are effective treatments for depression, new research finds. They could be used as alternatives to drugs or in addition to them, the researchers suggest. The type of yoga used in the study is named after B. K. S. Iyengar. It is a form of Hatha yoga and focuses on being precise in the postures and the control of the breathing. For the study, 30 people were given yoga classes and told

Most People Don’t Know This Is The Best Way To Empathise

Most People Don’t Know This Is The Best Way To Empathise

People are mistaken about the best way to understand other people’s minds. The best way to know other people’s minds is to put yourself in their shoes, new research suggests. This is not what people expect, though. Instead, people assume that reading facial expressions and body language is a better way of understanding the emotional states of others. Study authors, Drs Haotian Zhou and Nicholas Epley said: “People expected that they could infer another’s emotions by watching him or her, when in fact they were more accurate when they were

This Little-Known Supplement Improves Sleep

This Little-Known Supplement Improves Sleep

Supplement found to buffer the body against stress and improve sleep. For a long time probiotics — the so-called ‘good bacteria’ in fermented foods and elsewhere — have been linked to all sorts of physical and psychological benefits. Now the lesser-known prebiotics are getting in on the act. Prebiotics are dietary fibres found in foods such as: Onions, leeks, artichokes, and chicory. Prebiotic fibre — also available as dietary supplements — can improve the health of your gut by helping beneficial bacteria to multiply. New research has found that prebiotics

This Common Beverage May Help Fight Dementia

This Common Beverage May Help Fight Dementia

Studies on both humans and mice have suggested a protective effect. Caffeine — along with 24 other compounds — could help to protect against dementia. The protective effect comes from an enzyme called NMNAT2 that was discovered last year. Professor Hui-Chen Lu, who led the study, said: “This work could help advance efforts to develop drugs that increase levels of this enzyme in the brain, creating a chemical ‘blockade’ against the debilitating effects of neurodegenerative disorders.” NMNAT2 plays a dual role. It guards neurons against stress and helps fight the
