Hyperhomocysteinemia as a significant risk factor for autism?

by Paul Whiteley in Questioning Answers

The findings reported by Naushad Shaik Mohammad and colleagues [1] provide some blogging fodder today and the suggestion of a link between some of the genetics of the folate pathway and the finding of elevated levels of homocysteine with [some] autism in mind.OK, from the start, the genetics of folate metabolism mentioned in the context of autism typically means reference to the quite well replicated finding of issues with the gene methylenetetrahydrofolate reductase (MTHFR) (see ........

Antibiotic brain part 3

by Paul Whiteley in Questioning Answers

"This study demonstrates an association between antibiotic use in the first year of life and subsequent neurocognitive outcomes in childhood."So said the findings reported by Slykerman and colleagues [1] who relied on data from the Auckland Birthweight Collaborative Study (an initiative set up to determine whether "internationally recognized risk factors for small-for-gestational-age (SGA) term babies were applicable in New Zealand") to examine the suggestion that early life antib........

Testing an Automated and Humane Way to Resolve Barking

by CAPB in Companion Animal Psychology Blog

Teaching a quiet behaviour using an automatic feeder is a promising solution to barking problems.Some dogs bark when their owner is out and they are left home alone. A recent study by Alexandra Protopopova  (Texas Tech University) et al investigates the effectiveness of a humane, automated approach to solving barking problems.The research was conducted because some owners use citronella or shock collars to try and prevent their dogs from barking. While the devices may sometimes work, there ........ Read more »

ADHD (symptoms) and pain

by Paul Whiteley in Questioning Answers

If a primary goal of medicine is to relieve pain and suffering then the paper by Andrew Stickley and colleagues [1] might provide an important insight into how medicine might be missing some important groups when it comes to the experience of pain "assessed by the degree to which it interfered with work activity in the previous month."Drawing on data from the English 2007 Adult Psychiatric Morbidity Survey (APMS) (a resource that has cropped up on this blog before), auth........

On the "increasing evidence for an association between vitamin D insufficiency and depression"

by Paul Whiteley in Questioning Answers

The quote titling this brief post - "increasing evidence for an association between vitamin D insufficiency and depression" - comes from the review by Parker and colleagues [1] who seem to be no strangers to reviewing evidence on a possible link between the sunshine vitamin/hormone and depression [2].Affiliated to the Black Dog Institute in Oz ('black dog' being used as a metaphor for depression for quite a few years), the authors surveyed the quite voluminous peer-reviewed research literat........

The Morning After: What We Learn from Halloween

by Aurametrix team in Aurametrix Blog

What can we learn from Halloween? A lot, judging by numerous scientific studies and less scientific surveys. Halloween could help to collect a wide range of extreme facial expressions, including highly negative situations when children discover their parents ate up all their Halloween candy. This is what was done in the recent study and an ongoing youtube challenge.  Smile! You are being watched [...] ... Read more »

HBOT and autism systematically reviewed again (and the same results?)

"To date, there is no evidence that hyperbaric oxygen therapy improves core symptoms and associated symptoms of ASD [autism spectrum disorder]."So said the results of the review by Xiong and colleagues [1] (open-access available here) completed under the auspices of the Cochrane Collaboration, leaders in the science and publication of systematic reviews (see here for another example).Looking at the collected peer-reviewed science on the topic of hyperbaric oxygen therapy (HBOT) for aut........

Haunting Delusions of Identity

The science behind real life zombies

by Dr. Jekyll in Lunatic Laboratories

In the spirit of Halloween we bring you the science fact and fiction behind the undead. Zombies, those brain loving little guys, (and girls) are everywhere. Sure, we are all familiar with the classic zombie, but did you know that we aren't the only zombie lovers out there? It turns out that nature has its own special types of zombies, but this isn't a science fiction movie, this is science fact! Sometimes fact can be scarier than fiction, so let's dive in.

Living with severe autism: families share their experiences

by Paul Whiteley in Questioning Answers

Appreciating that the autism spectrum is truly a wide and heterogeneous one (or even several?), I'd like to direct your attention today to the findings reported by Jocelyn Bessette Gorlin and colleagues [1] on the topic of "the experiences of families living with a child with severe autism."In particular, I'd like to highlight the six areas that emerged from the "29 interviews with 22 participants from 11 families" related to family experiences and how, minus any sweeping generalisations, m........

Choosing your jurors: On bias, curiosity and  wisdom

by Doug Keene in The Jury Room

Earlier this week, we wrote on the question of whether those who have a higher score on the Need for Cognition Scale are just lazy (and the answer was no, not really). If you read this blog regularly, you know that bias is where we work and focus. We also like a curious juror (sometimes) […]

Lower autism rate under DSM-5 (yet again)

So: "Results indicate that individuals diagnosed with PDD [pervasive developmental disorder] by DSM-IV-TR criteria may not be diagnosed using DSM-5 criteria."That was the conclusion reached by Ferhat Yaylaci & Suha Miral [1] following their study of 150 children (3-15 years old) diagnosed with PDD "by DSM-IV-TR" whose symptoms/presentation were "reviewed through psychiatric assessment based on DSM-IV-TR and DSM-5 criteria." The percentage figure they arrived at (19.3%) indicat........ Read more »

Dogs Do as You Do, Not as You Say

by Elizabeth Preston in Inkfish



Italy's school for water rescue dogs, the Scuola Italiana Cani Salvataggio, has trained hundreds of animals in canine heroics. The dogs work on Italian police and coast guard boats, and with fire departments and the navy. They can even jump into the ocean from a hovering helicopter to save a person.

They're pros at taking commands from humans. So researchers wondered if the dogs could help them understand what kind of command works best: Words? Or gestures?

Advances in the Psychology of Passing the Salt

by Neuroskeptic in Neuroskeptic_Discover



I just came across a remarkable new paper on the science of salt-passing behavior: Expected Results Show that a Longer Nose Means Slower Times for Passing the Salt and Pepper: A Second Report



The article, which I have no doubt is entirely serious in nature, lists as its authors Canadian researchers Minér Patrick, Léon Le Néz and Pat Minér.

Here's how Patrick et al. describe their work:

Autism and inborn errors of metabolism

by Paul Whiteley in Questioning Answers

I'd like to think that the review article by Annik Simons and colleagues [1] (open-access) highlights some pretty strong evidence to suggest there being at least some connection between some autism and some of the collected inborn errors of metabolism. Indeed, when people generally talk about 'not knowing what causes autism' if we perhaps consider a more plural view of 'the autisms', there is a case to be made to say we might know what causes 'some' autism and some of it might lie in this area..........

Study Shows Just How Stressed Dogs Are at the Vet's

by CAPB in Companion Animal Psychology Blog

Most dogs show signs of impaired welfare at the vet, according to their owners.A survey of 906 dog guardians in Italy found most people report their dog as being stressed at all stages of the visit to a vet clinic, from being in the waiting room to being examined by the vet. 6.4% of dogs had actually bitten their guardian at the vet and 11.2% had growled or snapped at the vet.The report by Chiara Mariti (University of Pisa) et al draws important conclusions about what owners and vets need to do ........

The title of this post is partially taken from the BBC take on the findings reported by Andrew Pickles and colleagues [1] detailing a long-term follow up (and slight adjustment to the calculation of behavioural scores) of the Preschool Autism Communication Trial (PACT). PACT by the way, is a strategy based on the important tenet of shared attention where: "The approach aims to help parents adapt their communication style to their child’s impairments and respond to their child with enhance........

Are spouse killers “wicked” or  “stressed”?

by Rita Handrich in The Jury Room

While it may be 2016, there are still some judges who view women and men differently even when they commit the same offense. When it comes to killing your spouse—apparently, the difference lies in the gender of the defendant. Australian researchers looked at the sentencing remarks from nine different judges from trials involving men killing […]
