Researchers have discovered that our brain actively takes sugar from the blood. Prior to this, researchers around the world had assumed that this was a purely passive process. An international team reports that transportation of sugar into the brain is regulated by so-called glial cells that react to hormones such as insulin or leptin; previously it was thought that this was only possible for neurons.

A bit of a lazy post for you today with lots of quotes based on the findings reported by Ragnar Nesvåg and colleagues  asking some important questions about 'off-label' use of antipsychotics.Drawing on population-based data from Norway concerning "which substances, and for which mental disorder diagnoses, antipsychotic drugs were prescribed to 0–18-year-old boys and girls" the conclusions drawn make for some interesting reading.So: "In total, 0.18% of Norwegian children and adolescent........

Should we have people providing "fake" acupuncture in the Emergency Department?
If so, how should we do this?
Since it is not the acupuncture, but the patient's reaction to the "ceremony of the placebo" that appears to be providing the pain relief, how many different ways might we vary the "treatment" to improve the placebo effect?... Read more »

There's a reason it's called a gut feeling. The brain and the gut are connected by intricate neural networks that signal hunger and satiety, love and fear, even safety and danger. These networks employ myriad chemical signals that include dopamine, a powerful neurotransmitter most famous for its role in reward and addiction.

"In this nationwide sample of live births we observed no association between induction of labor and offspring ASD [autism spectrum disorder] within sibling comparison.

If you read my blog often, it's no surprise I suffer from PTSD, depression, and anxiety issues. Maybe it's from my military service, but maybe it's my father's, or his father's, maybe it's an insidious family legacy that was just never noticed. This is because having both parents and grandparents with major depressive disorder (MDD) was associated with higher risk of MDD for grandchildren, which could help identify those who may benefit from early intervention.

Although research stories stating a link (an association if you will) between condition A and factor X make for interesting reading, not all science is so blessed with such news-worthy findings. That's not to say that 'negative findings' are any less important than the 'hey, we found this...' studies, just that they don't perhaps tend to grab the headlines as much as those finding something.In saying all that I'm standing up for negative findings today and some rather interesting science reporte........

"Comorbid anxiety symptoms are ubiquitous among psychiatric patients with mood or schizophrenia spectrum disorders, and in almost half of them, reportedly severe."So said the findings reported by Karpov and colleagues  who sought to put some further research flesh on to the bones of the idea that clinically relevant anxiety symptoms might not be unstrange bedfellows with a variety of other psychiatric labels.Based on the analysis of various patient groups included in the "Helsinki University ........

I tread carefully in discussing the findings reported by Karola Dillenburger and colleagues  (open-access) on the question of "knowledge and training with regards to autism" received by "health, social care, and education staff who work within the statutory autism services sector in the UK." The observation that "an acute lack of autism-specific training that has detrimental impacts" was apparent is a worrying sign indeed.Although not intimately involved in the autism services sector, I ........

Feeling stiff first thing in the morning? It's not your imagination, new research has found a protein created by the body's "biological clock" that actively represses inflammatory pathways within the affected limbs during the night. This protein, called CRYPTOCHROME, has proven anti-inflammatory effects in cultured cells and presents new opportunities for the development of drugs that may be used to treat inflammatory diseases and conditions, such as arthritis.

The idea that use of the diagnostic label called attention-deficit hyperactivity disorder (ADHD) is on the increase, and pretty significantly so, is quite common-place these days (see here).

Long before Zika virus made it a household word, the birth defect called microcephaly puzzled scientists and doctors -- even as it changed the lives of the babies born with it during the pre-Zika era. But new discoveries reported by an international team of scientists may help explain what happens in the developing brains of babies still in the womb, causing them to be born with small brains and heads.

Many lower organisms retain the miraculous ability to regenerate form and function of almost any tissue after injury. Humans share many of our genes with these organisms, but our capacity for regeneration is limited. So scientists are studying the genetics of these organisms to find out how regenerative mechanisms might be activated in humans.
