"

Scientists carrying out a gambling experiment found the worst performers tended to be those who regularly used platforms such as Facebook.

The same trend was also observed among people who are reliant on drugs such as cocaine and heroin.

"Around one-third of humans on the planet are using social media, and some of these people are displaying maladaptive, excessive use of these sites," said lead researcher Dr Dar Meshi, from Michigan State University."

Relatos de sonhos diferentes conforme saúde mental?

Cientistas brasileiros criam programa para diagnosticar esquizofrenia e transtorno bipolar através do relato de sonhos

http://noticias.r7.com/tecnologia-e-ciencia/cientistas-brasileiros-criam-programa-para-diagnosticar-esquizofrenia-e-transtorno-bipolar-atraves-do-relato-de-sonhos-10082018

Citando:
"Os discursos dos pacientes foram transcritos e inseridos no programa de computador, que os transformou em grafos. Os relatos do dia dos três grupos não foram muito diferentes uns dos outros. Quando eles contam seus sonhos, no entanto, as diferenças apareceram. Elas ficaram bem evidentes entre os esquizofrênicos e bipolares.

Os relatos dos primeiros, representados por grafos, apresentam menos ligações do que os demais. Eles costumam falar de forma lacônica e com pouca digressão (desvio de assunto), o que explica por que a conectividade e a quantidade de arestas dos seus grafos são menores em comparação às dos bipolares, que, por sua vez, tendem a apresentar um sintoma oposto, a logorreia.

Citando:
"Psychedelic drugs like LSD and ecstasy ingredient MDMA have been shown to stimulate the growth of new branches and connections between brain cells which could help address conditions like depression and addiction.

Researchers in California have demonstrated these substances, banned as illicit drugs in many countries, are capable of rewiring parts of the brain in a way that lasts well beyond the drugs' effects."

Exercício fisico e depressão

Citando:
"Isto porque a atividade física potencia a libertação de endorfinas, que atuam como um poderoso analgésico natural. Mas não só. De acordo com a revista Time, a prática de exercício físico desencadeia a libertação de substâncias químicas no cérebro, diretamente relacionadas com o humor - serotonina, dopamina e noradrenalina - que têm ação no alívio da dor e do stress. Funciona ainda como um escape em relação aos pensamentos negativos, motores do stress, ansiedade e, em última instância, a depressão, porque exige a total concentração da pessoa que a pratica."

Ketogenic diets e o efeito profundo no cérebro (em ratos)

"Ketogenic diets are this year’s weight-loss silver bullet. While we should approach every diet with a healthy dose of skepticism, the more studies being conducted on ketosis—the state your body enters when producing elevated amounts of ketone bodies, which are constructed via fatty acid metabolism in your liver—the more the benefits are accruing. 

Weight loss is a continually trending topic, though such popular pastimes sometimes lead to deeper inquiry. In the case of ketogenic diets, two new studies published in Cell Metabolism show how cutting back carbohydrates and intermittent fasting not only helps with weight, but may stretch out your life while improving your memory along the way—in mice, at least. "

Saúde mental em jovens e vida na cidade estudada

Viver na cidade e com problemas com vizinhos aumenta o risco de psicoses em jovens?
https://www.theguardian.com/society/2017/may/23/city-living-teens-greater-risk-psychotic-experiences

Citação:
"It drew on the Environmental Risk Longitudinal Twin Study, in which 2,063 18-year-olds in England and Wales were asked whether they had had any psychotic experiences since the age of 12, including delusions, hallucinations or concerns that their food had been poisoned. Just over 30% of the teens reported at least one psychotic experience over the period.

Once factors including family psychiatric history, socioeconomic status and alcohol or cannabis dependence were taken into account, the odds were 43% higher for adolescents living in very urban settings – such as cities like London or Birmingham – than for rural teens.

Further analysis revealed the effect was at least in partly down to low levels of social cohesion, meaning poor relationships between neighbours, and high levels of neighbourhood disorder."

Efeitos do tempo na disposição estudados

E o número de horas de sol parece ser a variável mais preponderante (não se está chuva ou não):
http://m.jamaicaobserver.com/mobile/news/How-much-sun-time-are-you-getting-_79603


Citando:
"Your day might be filled with irritatingly hot temperatures, thick air pollution and maybe even pockets of rainclouds, but that won’t necessarily get you down. If you’re able to soak up enough sun, your level of emotional distress should remain stable. Take away sun time, though, and your distress can spike. This applies to the clinical population at large, not just those diagnosed with Seasonal Affective Disorder.
“That’s one of the surprising pieces of our research,” said Mark Beecher, clinical professor and licensed psychologist in BYU Counselling and Psychological Services. “On a rainy day, or a more polluted day, people assume that they’d have more distress. But we didn’t see that. We looked at solar irradiance, or the amount of sunlight that actually hits the ground. We tried to take into account cloudy days, rainy days, pollution . . . but they washed out. The one thing that was really significant was the amount of time between sunrise and sunset.”"

Saúde mental no Reino Unido

... A degradar-se desde o último inquérito:
http://m.huffpost.com/uk/entry/12262340
Citando:
"The seven years since the last Adult Psychiatric Morbidity Survey has seen the start of a major change in the way our society views mental health. A notable shift in public attitudes towards mental health is underway, and mental health issues are now widely recognised.

Factors such as recession, poverty and unemployment have adversely affected the mental health of the nation, leading to an increase in demand for help and support and at the same time, services are under enormous pressure.

The data paints a stark picture. In some groups of the population it is stabilising, while in other groups it is worsening. Nowhere is it improving. We can now start to see the true scale of an issue which has been stigmatised for centuries and it is deeply worrying for all. "
