A 'frank' presentation of autism?

by Paul Whiteley in Questioning Answers

"Many individuals with ASD [autism spectrum disorder] have a distinctive behavioral presentation that is recognizable within moments, a phenomenon we call "frank" ASD." So said the paper by Ashley de Marchena & Judith Miller [1] who carried out an "empirical study of frank ASD" and by the looks of my Twitter feed when I initially posted about this study, there are quite a few varied opinions about the concept of 'frank' autism.Although 'frank autism' makes up a significant portion ........

"A Putative Blood-Based Biomarker for Autism Spectrum Disorder-Associated Ileocolitis"

by Paul Whiteley in Questioning Answers

Contrary to Murphy's Law - 'never repeat a successful experiment' - replication or reproducibility is a cornerstone of good science. Today, I'm blogging about a piece of research that aimed to do just that as per the findings reported by Stephen Walker and colleagues [1] (open-access).The title of this post has been borrowed from the title of the Walker paper to illustrate how moving on from the quite widely known 'fact' that functional gastrointestinal (GI) symptoms are over-represented wh........

8.6% of children with autism have epilepsy?

by Paul Whiteley in Questioning Answers

"Epilepsy was reported to co-occur in 8.6 % of ASD [autism spectrum disorder] cases."That was the headline conclusion reported by Shiny Thomas and colleagues [1] as they drew on data from "the most recent U.S. National Survey of Children's Health, 2011-2012" to add to the extensive literature looking at how common epilepsy is when it comes to autism.Including some 1600 children/young adults diagnosed with autism - equivalent to a prevalence of 1.8% of the entire 85,000-strong co........

Sensory subtypes and anxiety and autism

by Paul Whiteley in Questioning Answers

"This is the first study to identify the existence of sensory subtypes among older children and adolescents with ASD [autism spectrum disorder] and explore their association with anxiety levels."Far be it from me to question the above quote provided in the paper by Mirko Uljarević and colleagues [1] but I'm inclined to suggest that there has already been some research published on the link between sensory issues and anxiety in the context of the autism spectrum before (see here and se........

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

Weight Training Boosts Brain Size and Performance

by William Yates, M.D. in Brain Posts

Aerobic exercise increases brain blood flow and has demonstrated beneficial effects on cognition.The effects of weight training exercise on the brain is less frequently studied. Hence, we know little about the effect and mechanism of weight training on brain function and performance.A recent study provides some needed insight on this topic.A study by C Suo and colleagues from Australia examined the effects of resistance training and cognitive skills training on brain structure and function.The k........

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........

Haunting Delusions of Identity

by The Neurocritic in The Neurocritic

Bugs Bunny in Hyde and Hare (1955)Delusional misidentification syndromes have fascinated filmmakers and psychiatrists alike. Afflicted individuals suffer under the false belief that persons or things around them have changed their identities or appearance.

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........

Lack of Tsc2 in Mesenchymal Cells Causes Kidney Cysts and Defective Lung Alveolarization

by Joana Guedes in BHD Research Blog

Tuberous sclerosis complex (TSC) is an autosomal dominant genetic disorder that shares clinical similarities with BHD. TSC results from germline mutations in the Tsc1 or Tsc2 gene, affecting multiple organs, including the kidney and lung. In the kidney, lesions such as multiple renal cysts and renal cell carcinoma can occur. In the lung, patients can develop multifocal micronodular pneumocyte hyperplasia and LAM. TSC proteins are negative regulators of the mTORC1 pathway. The mechanisms of organ........ Read more »

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."
