Could an "ill-state" associated with anorexia nervosa mimic the symptoms of autism?

by Paul Whiteley in Questioning Answers

The question posed in the title of this post 'Could an "ill-state" associated with anorexia nervosa mimic the symptoms of autism?' stems from the findings reported by Heather Westwood and colleagues [1] (open-access).They continued a research theme looking at the potential 'overlap' when it comes to autism and eating disorders such as anorexia nervosa (AN) (see here). Notably, researchers questioned whether the finding that some 50% of their cohort "scored above the clinical cut-off on the ........ Read more »

Gender disparities in science persist despite significant advances

by SciELO in SciELO in Perspective

The participation of women as authors in academic publications has been increasing significantly worldwide and in all areas of knowledge, reaching 49% in Brazil and Portugal, followed by Australia (44%) and the European Union (41%). Gender equity in science, however, still has a long way to go, especially in the editing and peer review functions. A study of more than 41,000 articles published between 2007 and 2015 shows that male editors - who are majority - preferentially select same gender ref........ Read more »

Know your brain: Preoptic area

by neurosci in Neuroscientifically Challenged

Where is the preoptic area?















the preoptic area is highlighted in blue.











Functionally, the preoptic area is considered to be a region of the hypothalamus even though its embryological origins are as part of the telencephalon (rather than the diencephalon like the rest of the hypothalamus). It consists of the area o........ Read more »

Sustainable hunting regulations take the speed of trophy growth into account

by sschindler in sschindlerblog

Hunting regulations aim to keep trophy hunting sustainable. Yet most regulations fall short of this aim and trophy size is becoming shorter over time in most hunted populations, such as Bighorn sheep, Impala, Mouflon, and Sable antelope. This might be due to ignoring the speed of trophy growth when deciding on hunting regulations. more Schindler, […]... Read more »

Conviction for violence and autism: comorbidity counts

by Paul Whiteley in Questioning Answers

I tread carefully when discussing the results published by Ragini Heeramun and colleagues [1] on the topic of "whether autism is associated with convictions for violent crimes" and "the associated risk and protective factors." Carefully because, as I've indicated on other occasions (see here), people commit crimes not labels, and sweeping generalisations about labels, specific types of crime and/or the concept of 'dangerousness' tend to do very little to help anyone in the long term.St........

Microwave emission as a proxy of CME speed in ICME forecasting by Carolina Salas Matamoros, Ludwig Klein and Gerard Trottet

by CESRA in Solar Radio Science

Coronal Mass Ejections (CMEs) are one type of interplanetary structure that mostly affect the geomagnetic field (e.g. Gonzalez and Tsurutani, 1987; Zhang et al, 2007). These structures are observed and studied through coronagraphic images. The basic limitation of the coronagraph is that it shows the corona only in the plane of the sky, and blocks by necessity the view on the solar disk. Thus, the projection effect in the kinematic [...]... Read more »

"Medical Conditions in the First Years of Life Associated with Future Diagnosis of ASD"

by Paul Whiteley in Questioning Answers

I rank the paper by Stacey Alexeeff and colleagues [1] (open-access available here) as being in the 'pretty important' category when it comes to hierarchy in autism research. Not only because of their use of data derived from Kaiser Permanente (KP) (quite a large US healthcare provider that has some autism research history) including some "3911 ASD [autism spectrum disorder] cases and 38,609 controls" but also because some of the findings reiterate what is already 'known' abo........

Let those who never smelled bad cast the first stone

Analysis of our metabolism is crucial to comprehending the responses of our genes and microbes to the stresses of daily life, and to elucidating the causes and consequences of health and disease. And measurement of urinary metabolites - small molecules produced from foods, drinks, drugs, environmental contaminants, bodily waste products and bacterial by-products - is key to the analysis. We applied this approach to an elusive condition that has always evaded diagnosis: s........

Neuropeptides and Peer Review Failure

by Neuroskeptic in Neuroskeptic_Discover

A new paper in the prestigious journal PNAS contains a rather glaring blooper.

The paper, from Oxford University researchers Eiluned Pearce et al., is about the relationship between genes and social behaviour. The blooper is right there in the abstract, which states that "three neuropeptides (β-endorphin, oxytocin, and dopamine) play particularly important roles" in human sociality. But dopamine is not a neuropeptide.



Neither are serotonin or testosterone, but throughout the paper, Pea... Read more »

Vitamin D genes and autism

"Vitamin D deficiency is a putative environmental risk factor for autism spectrum disorder (ASD)."And..."We provide straightforward genetic evidences for the first time that VDRGs [vitamin D-related genes] with a strong degree of DNM [de novo mutations] burden in ASD and DNMs of VDRGs could be involved in the mechanism underlying in ASD pathogenesis."That was the research bottom line reported on by Jinchen Li and colleagues [1] examining an important part of the whole 'vitami........

Is "Allostasis" The Brain's Essential Function?

by Neuroskeptic in Neuroskeptic_Discover

A paper just published in Nature Human Behaviour makes some big claims about the brain. It's called Evidence for a large-scale brain system supporting allostasis and interoception in humans, but how much is evidence and how much is speculation?



The authors, Ian R. Kleckner and colleagues of Northeastern University, argue that a core function of the brain is allostasis, which they define as the process by which the brain "efficiently maintains energy regulation in the body". Allostasis ent... Read more »
