When research has more fairly compared PS-I with I-PS, it has concluded that, in general, the sequence doesn't matter all that much, though there are some positive trends on conceptual and transfer assessments for PS-I.... Read more »

A diet high in saturated fat can make your brain struggle to control what you eat. If people are looking to lose weight, stay clear of saturated fat. Consuming these types of fatty food affects a part of the brain called the hypothalamus, which helps regulate hunger.

I was really, really pleased to read the paper by Melanie Uhde and colleagues  (open-access) I don't mind telling you. Covering a topic close to my blogging and research heart - sensitivity to wheat or gluten but not coeliac disease - the authors provide some much needed scientific clarification when it comes to how gluten or wheat might impact on some of those "who reported symptoms in response to wheat intake and in whom coeliac disease and wheat allergy were ruled out." Some media int........ Read more »

Science headlines eh? Who would trust them and their sometimes inflated press releases?I start today with a science headline taken from the BBC website reading: "Pregnancy multivitamins 'are a waste of money'" based on the findings of a review article  published in the journal Drug and Therapeutics Bulletin.In it we are told that complex multi-vitamin and mineral supplements are 'unlikely to be needed and are an unnecessary expense' during the nine months that made us. Further that certain vi........ Read more »
Medication roulette, if you have ever had to deal with depression or other types of mental illness you know what I'm talking about. You take a pill that could help or could cause all sorts of horrid side effects. You cross your fingers as you take that first pill and in the 4-6 weeks it takes to start working you cross your fingers, hope, wish and probably even dread the outcome. But why does it take so long for antidepressants to start working in the first place and what could be done to c........ Read more »

The paper by Traolach Brugha and colleagues  makes for some blogging fodder today and the suggestion that: "The combined prevalence of autism in adults of all ages in England was 11/1000."Just before going through the Brugha paper it is perhaps appropriate to put it into some context based on other work from this group previously covered on this blog (see here) and the findings again by Brugha and colleagues  (a further report on their findings that time around can be seen h........

A team of Toronto scientists has found similarities in brain impairments in children with autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD) and obsessive compulsive disorder (OCD). The study involved brain imaging of white matter in 200 children with autism, ADHD, OCD or no diagnosis.

If you're ever lost in a remote European forest, you might be able to get your bearings by finding a herd of roe deer. These animals like to align themselves roughly north-south, whether they're standing still or fleeing danger.
Roe deer are small, reddish or grayish grazers common in Europe and Asia. Petr Obleser, of the Czech University of Life Sciences in Prague, and his coauthors studied the behavior of these skittish herbivores to look for evidence that they can sense the earth's ma........ Read more »
One would think that people with few friends and living in poverty are more at risk for PTSD than those with a strong support network and many resources. And that's true.
However, it is a different story when you look at the country-, rather than the individual level. Countries with more resources, such as the USA and the Netherlands, have higher levels of PTSD than countries with fewer resources (e.g. Colombia, South Africa).

Food puzzles will help satisfy your cat’s hunting instinct, but most cats are missing out.A new paper on food puzzle toys for cats has plenty of ideas to get everyone started on these wonderful enrichment items.

"The meta-analysis provided evidence for higher blood glutamate levels in ASD [autism spectrum disorder]."That was the research bottom-line reported by Zhen Zheng and colleagues  (open-access available here) who surveyed the current peer-reviewed science literature in this area and found something to see based on: "Twelve studies involving 880 participants and 446 incident cases."Drawing on the idea that glutamate is a rather important amino acid that plays a role in various biological p........

I going to assume that readers have some background knowledge about probiotics, gut bacteria, bacterial dysbiosis and coeliac disease before reading this post. I'd love to be able to give detailed descriptions of each here but fear that this would turn a short post into a much longer one...So... in a previous post titled: 'Probiotics degrading gluten peptides?'

I very carefully approach the findings reported by Jennifer Fairthorne and colleagues  today detailing "the occurrence of hospital admissions and treatment/services for cancer in mothers of children with ASD [autism spectrum disorder] with or without ID [intellectual disability] compared with other mothers." Appreciating that families touched by autism probably have enough on their plate without additional talk about the 'big C', I do however think that this kind of r........ Read more »

Capitalizing on experimental genetic techniques, researchers have demonstrated that temporarily turning off an area of the brain changes patterns of activity across much of the remaining brain. The research suggests that alterations in the functional connectivity of the brain in humans may be used to determine the sites of pathology in complex disorders such as schizophrenia and autism.

The brain's reward centers in severely obese women continue to respond to food cues even after they've eaten and are no longer hungry, in contrast to their lean counterparts. The study compared attitudes and the brain activity of 15 severely obese women (those with a body mass index greater than 35) and 15 lean women (those with a BMI under 25).

Granted, I am taking a slight departure from the material typically discussed on this blog by introducing the paper by Yan Zhang and colleagues  who reported the findings of a meta-analysis examining "the efficacy of different probiotic types, doses and treatment durations in IBS [irritable bowel syndrome] patients diagnosed by Rome III criteria via a meta-analysis of randomized controlled trials (RCTs)." The results however - "Probiotics are an effective pharmacological t........ Read more »

Ever feel like someone is hiding something? Or maybe you suddenly feel like you can't trust a co-worker. The feeling may seem logical, but is empathy the result of gut intuition or careful reasoning? Research suggests that, contrary to popular belief, the latter may be more the case.

People who perform regular altruistic acts like giving blood also tend to have more sex.Viewed through the lens of evolutionary psychology, altruism takes some explaining. In a dog eat dog world, it seems like a risky, indulgent habit. Yet we are only alive today because our distant ancestors were successful at reproducing – and the fact many of us have inherited their altruistic tendencies suggests that being altruistic gave them some kind of survival or reproductive advantage.One idea i........

I can't profess to be an expert on the techniques called sigmoidectomy and appendicostomy so won't even try and pretend that I am. From what I gather from Dr Google, the latter is a surgical technique generally performed to "help deliver enemas more easily" to relieve constipation, whilst the former involves the surgical removal of some or all of the sigmoid colon. Both are only generally indicated when traditional methods of treating constipation for example, fail.The reason I'm briefly ta........ Read more »
