On ADHD medication and motor vehicle crashes

by Paul Whiteley in Questioning Answers

"Among patients with ADHD [attention-deficit hyperactivity disorder], rates of MVCs [motor vehicle crashes] were lower during periods when they received ADHD medication."That was the research bottom-line discussed by Zheng Chang and colleagues [1] who continue a theme on how managing/treating the symptoms of ADHD can often have some profound effects on those diagnosed with ADHD and also the wider population.The outcome measure on this occasion was MVCs; in particular: "E........

Gaslighting in the Medical Literature

by The Neurocritic in The Neurocritic

Have you felt that your sense of reality has been challenged lately? That the word “truth” has no meaning any more? Does the existence of alternative facts make you question your own sanity? In modern usage, the term gaslighting refers to “a form of psychological abuse in which false information is presented to the victim with the intent of making him/her doubt his/her own memory and perception”.Gaslighting is a form of manipulation that seeks to sow seeds of doubt in a targeted ........

Blood heavy metal levels and autism (yet again)

by Paul Whiteley in Questioning Answers

"Data showed that the children with ASD [autism spectrum disorder] had significantly (p < 0.001) higher levels of mercury and arsenic and a lower level of cadmium."And... "It is desirable to continue future research into the relationship between ASD and heavy metal exposure."Those sentences come from the study by Huamei Li and colleagues [1] continuing a research theme regarding (generally) elevated levels of heavy metals being detected in those on the autism spectrum (see here).

Unreliability of fMRI Emotional Biomarkers

by Neuroskeptic in Neuroskeptic_Discover

Brain responses to emotion stimuli are highly variable even within the same individual, and this could be a problem for researchers who seek to use these responses as biomarkers to help diagnose and treat disorders such as depression.

That's according to a new paper in Neuroimage, from University College London neuroscientists Camilla Nord and colleagues.



Nord et al. had 29 volunteers perform three tasks during fMRI scanning. All of the tasks involved pictures of emotional faces, which... Read more »

The Invisibility Cloak Illusion: We are more observant (and  yet, less observed) than all others

by Rita Handrich in The Jury Room

This is the sort of article that can either amuse or terrify you. It will amuse you if you are charmed by all the ways in which we see ourselves as superior to others. And it will terrify you if you do not want to know that you are always being observed closely by everyone […]... Read more »

Irritable bowel syndrome (IBS) as a risk factor for bipolar disorder

by Paul Whiteley in Questioning Answers

"Only irritable bowel syndrome (IBS) emerged as a risk factor for BD [bipolar disorder] supported by convincing evidence."So said the results of the umbrella review of systematic reviews and meta-analyses by Beatrice Bortolato and colleagues [1] looking at the various environmental risk factors potentially linked to the diagnosis of bipolar disorder. I might add that this is a topic that has been discussed before on this blog (see here and see here for examples).If the systematic ........ Read more »

Dismantle the Poverty Trap by Nurturing Community Trust

by Jalees Rehman in The Next Regeneration

Understanding the precise reasons for why people living in poverty often make decisions that seem short-sighted, such as foregoing more education or taking on high-interest short-term loans, is the first step to help them escape poverty. The obvious common-sense fix is to ensure that the basic needs of all citizens – food, shelter, clothing, health and personal safety – are met, so that they no longer have to use all new funds for survival. This is obviously easier in the developed w........ Read more »

Multi-Loop Structure of Nonthermal Microwave Sources in a Major Long-Duration Flare by V. Grechnev et al.*

by CESRA in Solar Radio Science

Hard X-ray (HXR) and microwave observations of flares show only a few nonthermal sources. They are simple and compact, especially in impulsive flares, suggesting involvement of one to two loops. Hanaoka (1996) and Nishio et al. (1997) interpreted these observations in terms of double-loop flares. This view was later extended up to long-duration flares (Tzatzakis, Nindos, and Alissandrakis, 2008). A concept of a simple flare loop became dominant. However, observations [...]... Read more »

"there is no single way for a brain to be normal" (or how 'neurotypical' is a nonsense)

by Paul Whiteley in Questioning Answers

I'm not usually so forthright with my posts on this blog, but today I'm being a little more bullish as I talk about an editorial from Simon Baron-Cohen [1] titled: "Neurodiversity – a revolutionary concept for autism and psychiatry."The crux of the SBC paper is the suggestion that use of the term 'disorder' specifically with autism in mind might have certain connotations - "Disorder should be used when there is nothing positive about the condition" - and until the "biomedical mechanistic cause........

Unraveling the Mysteries of Mischievous Microbiome

by Aurametrix team in Aurametrix Blog

Science explains why some people smell worse than others despite keeping themselves squeaky clean. The body is crawling with bacteria increasing the risk for diseases for which we have unreserved levels of sympathy. It can also lead to ​unlikable conditions such as unpredictable and embarrassing outbursts of body odor - so bad it ruins social lives and careers.  But there is no cure for metabolic body odor ...

"a gluten-related subgroup of schizophrenia"?

A quote to begin this post: "this preliminary study demonstrates that altered AGDA [antibodies against gliadin-derived antigen] levels in the circulation are associated with schizophrenia and could serve as biomarkers for the identification of a schizophrenia subgroup that may need an alternative therapy or precision treatment."So said the findings reported by McLean and colleagues [1] (open-access) looking at an area of some interest to this blog (see here) on how dietary gluten might........

A Survey of Our Secret Lives

by Neuroskeptic in Neuroskeptic_Discover

What kinds of secrets does the average person keep? In a new paper, Columbia University researchers Michael L. Slepian and colleagues carried out a survey of secrets.



Slepian et al. developed a 'Common Secrets Questionnaire' (CSQ) and gave it to 600 participants recruited anonymously online. Participants were asked whether they'd ever had various secrets, at any point in their lives. The results are a monument to all our sins:

It turns out that extra-relational thoughts - meaning "thou... Read more »

Gastrin-releasing peptide and autism continued

Yet another 'continued' or 'part 2' short post for you today, building on some previous - very preliminary research - talking about the use of gastrin-releasing peptide (GRP) and autism (see here).The authors included on the paper by Josemar Marchezan and colleagues [1] are familiar ones to this part of the autism research landscape as per the other occasions that members of this group have looked at / talked about GRP and autism in the peer-reviewed domain.GRP is all about a compound that 'does........

Characterization of a FLCN mutation associated with RCC

by Joana Guedes in BHD Research Blog

Mutations in the FLCN gene are the cause of Birt-Hogg-Dubé (BHD) syndrome, a rare disease characterized by renal cell carcinoma (RCC), pneumothorax and fibrofolliculomas. In their new study, Bartram et al. (2017) identify a heterozygous mutation in the FLCN gene in a patient with RCC. DNA from tumour and a metastasis was analysed and the authors demonstrated skipping of exon 11 as the consequence of this mutation leading to a shift in the reading frame and the insertion of a premature sto........

Injury risk and ADHD: part 2

On vaccinated and un-vaccinated homeschooled children: the disappearing-reappearing-disappearing-reappearing studies

by Paul Whiteley in Questioning Answers

I originally began writing this post in the last week of November 2016 following first sight of the study abstract by Anthony Mawson and colleagues [1] and their journey into a topic that has had its fair share of discussion/argument* (*delete as appropriate) with autism in mind down the years: are vaccines or immunisation patterns potentially linked to [some] autism?As it happened, this post was shelved for some time because (a) only an abstract appeared despite a publication date accompan........
