Coeliac disease, autism and more

by Paul Whiteley in Questioning Answers

"Compared with the general population, children with celiac disease had a 1.4-fold greater risk of future psychiatric disorders. Childhood celiac disease was identified as a risk factor for mood disorders, anxiety disorders, eating disorders, behavioral disorders, ADHD [attention-deficit hyperactivity disorder], ASD [autism spectrum disorder], and intellectual disability."So said the study findings reported by Agnieszka Butwicka and colleagues [1] who, yet again, relied on one of ........

[Objective] exposure to flame retardants and social behaviours

by Paul Whiteley in Questioning Answers

Although a few details of the study reported by Shannon Lipscomb and colleagues [1] (open-access) interested me, I was particularly taken by their use of "a silicone passive wristband sampler [worn] around his/her wrist or ankle" to "assess the child’s exposure to flame retardants" as part of their investigation "to determine if flame retardant exposure was associated with measurable differences in social behaviors among children ages 3–5 years."I've covered the topic of potential adver........

The retina receives signals from all over the brain, and that is kind of weird

As a neuroscientist, when I think of the retina I am trained to think of a precise set of neurons that functions like a machine, grinding out the visual basis of the world and sending it on to the brain. It … Continue reading →... Read more »

L-methylfolate administration and autism: a case report

by Paul Whiteley in Questioning Answers

I should have really titled this post 'another case report' given yesterday's entry on this blog talking about a case of [untreated] PKU and autistic behaviours/diagnosis. Here I am again talking about another N=1 with autism in mind and specifically the findings reported by Kim Siscoe & David Lohr [1] on how: "L-methylfolate supplementation improved symptoms of aggression and disruptive behavior in a child with autism who tested positive for the C677TT allele of the methyltetrahydrofolate r........

Bottlenose Dolphins: The Ultimate Sea Bully? (A Guest Post)

by Miss Behavior in The Scorpion and the Frog

By Kayla FullerImagine this situation: you’ve brought your favorite lunch to work. Everyone is jealous of your food, continuously eyeing it up. A few coworkers, who have brought in disappointing lunches in comparison, approach and demand that you hand it over. After you refuse, they beat you until your body lies lifeless and they take your lunch anyway. Woah, woah, woah… that took a dramatic turn!

Caterpillars Recruit Friends with Anal Scraping

by Elizabeth Preston in Inkfish



Newly hatched caterpillars look helpless: they're teensy, soft and juicy, with no parent around for protection. But certain young insects, the masked birch caterpillars, are more capable than they seem. They gather in groups to keep themselves safe. To form those groups, they use a previously undiscovered language of buzzes, vibrations, head banging and butt scraping.



The species, Drepana arcuata, passes through five caterpillar life stages (called instars) on its way to becoming a li... Read more »

Radio Diagnostics of Electron Acceleration Sites During the Eruption of a Flux Rope in the Solar Corona by Eoin Carley et al.*

by CESRA in Solar Radio Science

Flares and coronal mass ejections (CMEs) are thought to result from magnetic energy release in the solar corona, often involving the destabilisation of a twisted magnetic structure known as a flux rope (Chen et al. 2011, Webb et al. 2012). This activity may be accompanied by the acceleration of electrons (Kahler 2007, Lin et al. 2011). However, there is ongoing debate on exactly where, when and how this particle acceleration occurs [...]... Read more »

Presenting with the symptoms of autism and then diagnosed with phenylketonuria (PKU)

by Paul Whiteley in Questioning Answers

The case report from Betül Mazlum and colleagues [1] (open-access available here) illustrates once again that (a) the plural 'autisms' exist (see here) and (b) screening for inborn errors of metabolism (IEM) should be an important part of any autism assessment (see here). Indeed, screening for IEM should really be part of assessments for many different labels...Detailing a case report wherein a 3-year old child came to clinical attention for "speech delay and social problems", the authors ........

Theory of Mind in Brain Development

by William Yates, M.D. in Brain Posts

Theory of Mind (ToM) is a concept describing the ability to understand what another person is thinking or feeling.Today in my neuroscience medicine news review I ran across a novel, interesting and important research study targeting brain development in ToM.Normally developing children develop ToM around 4 years of age. In the study published in Nature Communications, a research team at the Max Planck Institute in Germany studied white matter development in 3 to 4 year old children.Using a serie........ Read more »

Being multilingual in school

by Madalena Cruz-Ferreira in Being Multilingual

P { margin-bottom: 0.08in; } Schooling nurtures development of academic ways of talking about things. This has come to be called ‘education’, in the sense that an ‘educated’ person is able to use language in this way. Schooling teaches us how, why and with whom our languages can be used to acquire knowledge formally, about history, chemistry, or geography, things that not all of us will have encountered at home, by these or any other names. It also teaches us that knowledge, of these a........ Read more »

Detecting stereotypic behaviours through technology

by Paul Whiteley in Questioning Answers

"We have designed an Internet-of-Things (IoT) framework named WearSense that leverages the sensing capabilities of modern smartwatches to detect stereotypic behaviors in children with autism."So said the paper by Amir Mohammad Amiri and colleagues [1] (open-access available here) and, I have to say, something that really piqued my [research] attention. Describing how authors managed to design and construct a smartwatch with the ability to "detect three behaviors, including hand flapping, pa........ Read more »

Multilingualism and disorders

by Madalena Cruz-Ferreira in Being Multilingual

P { margin-bottom: 0.08in; } Norms of conduct, including linguistic norms, are social constructs. They vary in space and time, and they can be of two types. Descriptive norms draw on observation and tell us what people do, for example that interrupting your conversation partners is common in parts of southern Europe (which can be a sign of polite engagement in the exchange), or that fermented herring is a delicacy in parts of northern Europe (which can be a sign of Nordic stoicism). Prescripti........ Read more »

Textbook languages

by Madalena Cruz-Ferreira in Being Multilingual

P { margin-bottom: 0.08in; } Wanting to learn a language doesn’t always result in learning the language that we want. This is so even when the language that we want to learn and the one that we end up learning go by the same name – let’s call it X. One reason for this is that most language teaching proceeds through what we’ve come to identify as the language’s holy writ, namely, the X textbook. A textbook is a book. Like all books, it uses printed modes of language, with two consequ........ Read more »

Multilingual novelties

by Madalena Cruz-Ferreira in Being Multilingual

P { margin-bottom: 0.08in; } Research on multilingualism has mushroomed over the past 50 years or so, which must be a good thing. Although some publications do take multilingual norms as multilingual norms, most research has proceeded through the bias of monolingual standards, which is not so good for the obvious reason that multilinguals aren’t monolinguals. Equally biased is the academic and media hype spawned by the flurry of interest in current multilingualism, which risks spawning, in t........ Read more »

Multilingual neuromyths

by Madalena Cruz-Ferreira in Being Multilingual

P { margin-bottom: 0.08in; } Neuromyths are misconceptions about how the brain works. They are the topic of the Nature Neuroscience editorial The mythical brain, which highlights that they are as false as they are appealing, and that their appeal is what explains their resilience.Appealing seems to be the key word here, in its sense of ‘engaging’ with little or no rational engagement. Deena Skolnick Weisberg and colleagues showed this in The seductive allure of neuroscience explanations: w........ Read more »
