The Link Between Sleep And Alzheimer’s Explained

During slow-wave or deep sleep, the brain is cleared of waste products. A single night of disrupted sleep is enough to increase a brain protein linked to Alzheimer’s, new research shows. A full week of poor sleep causes increases in another brain protein that is also linked to Alzheimer’s. The findings may help to explain why poor sleep has been linked to Alzheimer’s. Professor David M. Holtzman, who led the study, said: “We showed that poor sleep is associated with higher levels of two Alzheimer’s-associated proteins. We think that perhaps

This Is The Number 1 Cause of Ill Health Worldwide

Depression is the leading cause of disability and ill health worldwide. There are over 300 million living with depression around the world. This represents an increase of 18% between 2005 and 2015, according to figures put out by the World Health Organisation (WHO). Almost 50% of people who are depressed do not get any treatment, even in high-income countries. Two important reasons are: Lack of support for people with mental health problems, and stigma. The WHO is currently running a year-long campaign called “Depression: let’s talk”. Dr Shekhar Saxena, Director

How Experiencing Joy Can Help Children and Promote Optimal Development

Joy is a powerful tool for solving childhood challenges. Yet in our culture of doing, teaching, treating and pathologizing, too often we forget that when a child needs help, the first thing we should increase is joy. This is certainly true in my own field, child psychology, in which we often prioritize theories, techniques and analyzing behaviors over being present and building relationships. The simple truth is that joy leads to healing and supports optimal development. I experienced this years ago in a sad moment for my family. My beloved

10 Minutes On These Beats Caffeine For Energy And Motivation

Afterwards people reported greater motivation to work and more energy. Walking up the stairs for 10 minutes beats a cup of coffee for increasing energy and motivation, new research finds. Researchers compared the effects of 10 minutes low-to-moderate intensity exercise with a 50mg of caffeine (around a cup of coffee or can of cola) and a placebo condition. Professor Patrick J. O’Connor, study co-author, said: “We found, in both the caffeine and the placebo conditions, that there was not much change in how they felt. But with exercise they did

Single Or Married: Which Is The Happiest Life?

Single Or Married: Which Is The Happiest Life?

The two surveys involved around 370,000 people in the UK. Being married brings people more lifelong happiness than being single, new research finds. The boost to happiness in being married also persists into old age. The positive effect of marriage is even stronger for those people who described their partner as their best friend. The findings were just the same for those people who lived together but were not actually married. Professor John Helliwell, study co-author, said: “Even after years the married are still more satisfied. This suggests a causal

This Work Habit Is Killing Your Wellbeing

This Work Habit Is Killing Your Wellbeing

Organisations should adjust their policies if they care about their employee’s wellbeing. People who do not separate their work-life from their private life are killing their well-being, according to new research. Habits like checking and responding to work emails at home or taking the laptop on holiday were linked to lower wellbeing in the study. Those who mixed work and free time were less likely to engage in activities that would help them recover, like hobbies or sports. So they returned to work more exhausted and with a lower sense

29% Lower Dementia Risk After This Training

29% Lower Dementia Risk After This Training

Dementia risk reduced in 10 1-hour sessions — benefits seen 10 years later. A type of mental exercise has been linked for the first time to a reduced risk of dementia. The training is called ‘speed processing’ and involves identifying objects and their location on a screen. As people improve at this cognitive task, the software speeds up. The speed training was effective where more traditional memory and reasoning training had little effect on dementia. Professor Frederick W. Unverzagt, who led the study, said it was comparatively easy training: “We

Coffee Has Surprising Effect On Mental Health

Coffee Has Surprising Effect On Mental Health

How coffee consumption is linked to both mental and physical health. Moderate coffee consumption is linked to reduced depression risk and lower levels of Parkinson’s and dementia, new research finds. Not only that, but the review of more than 200 studies found that drinking 3 to 4 cups of coffee a day is linked to many other benefits. These include lower levels of heart disease, reduced risk of some cancers, diabetes and liver disease. The study’s authors write: “Coffee consumption was consistently associated with a lower risk of Parkinson’s disease,

The Herbal Antidepressant With Serious Side-Effects

The Herbal Antidepressant With Serious Side-Effects

Despite being perceived as safe by the general public, herbal medicines actually carry considerable risks. St John’s Wort — a popular herbal treatment for depression — can have serious side-effects, research finds. These include dangerous changes in body temperature and blood pressure. The research compared the side-effects of St John’s Wort with those of fluoxetine — an antidepressant also known as Prozac, Animex-On, Sarafem, Adofen and Deprex. The side-effects of St John’s Wort were just as serious as for the antidepressant. These included: anxiety, panic attacks, dizziness, vomiting, amnesia and

Asking One Simple Question Improves Your Relationship

Asking One Simple Question Improves Your Relationship

People in the study were encouraged to think about conflicts in their relationships in a new way. “How will I feel in one year about this current conflict in my relationship?” Asking a question with a future-orientation helps people feel more positive about their relationship, a study finds. People feel more forgiving and interpret their relationship in a more positive light when they think about it from a future perspective. Mr Alex Huynh, the study’s first author, said: “When romantic partners argue over things like finances, jealousy, or other interpersonal

The Linguistic Trick That Helps You Cope With Strong Emotions

The Linguistic Trick That Helps You Cope With Strong Emotions

It is a way of expressing universal, shared experience and creating some emotional distance. People use the word ‘you’ when they really mean ‘I’. It helps to distance them from negative emotional experiences, new research finds. For example, the expression “you win some, you lose some” probably means the person has failed, but that it could happen to anyone. The pronoun, therefore, helps you to feel better about the experience. Ariana Orvell, the study’s first author, explained: “When people use “you” to make meaning from negative experiences, it allows them

This Sleep Pattern Leads To Faster Learning That Lasts Longer

This Sleep Pattern Leads To Faster Learning That Lasts Longer

50% improvement in learning from this sleep technique. Sleeping in between study sessions could be the key to better recall, new research finds. The technique aids recall up to six months later, psychologists have found. Dr Stephanie Mazza, the study’s first author, said: “Our results suggest that interleaving sleep between practice sessions leads to a twofold advantage, reducing the time spent relearning and ensuring a much better long-term retention than practice alone. Previous research suggested that sleeping after learning is definitely a good strategy, but now we show that sleeping

The Most Severe Personality Disorder Weakens Empathic Brain Activity

The Most Severe Personality Disorder Weakens Empathic Brain Activity

Why people with the most severe personality disorder find it difficult to have romantic relationships and friendships. People with borderline personality disorder have deficits in brain regions related to empathy, new research finds. The finding helps explain why people with borderline personality disorder have unstable moods. They also often have trouble maintaining relationships with others. Dr Brian Haas, the study’s lead authors, said: “Our results showed that people with BPD traits had reduced activity in brain regions that support empathy. This reduced activation may suggest that people with more BPD

How To Have An Extraordinary Memory At 80

How To Have An Extraordinary Memory At 80

Superagers reveal how we can all age gracefully. Warm and trusting social relationships could be the key to having an extraordinary memory when you are 80. The conclusion comes from new research on so-called ‘superagers’ — people who have the cognitive abilities of those up to 30 years younger. The decline in superager’s memory and other cognitive skills is much slower than their peers. They also report having more high-quality and satisfying relationships with other people. Dr Emily Rogalski, a study author, said: “You don’t have the be the life
