Wandering and autism continued... yet again

by Paul Whiteley in Questioning Answers

I know that I'm probably starting to sound like a broken record on the topic of wandering (elopement) and autism on this blog (see here and see here and see here) but I am yet again going to briefly talk about peer-reviewed research in this area simply because it's just too damned important not to.This time around the results from Catherine Rice and colleagues [1] are the source of my musings and the conclusion that: "wandering among children with ASD [autism spectrum disorder], regard........

CRISPR-Cas9 and autism research

by Paul Whiteley in Questioning Answers

If you feel brave enough, today I will direct your reading attention to the paper by Michael Williams and colleagues [1] detailing the application of a particularly important genome editing technique called CRISPR-Cas9 [2] to autism-related science.Titled: "A Retroviral CRISPR-Cas9 System for Cellular Autism-Associated Phenotype Discovery in Developing Neurons" the Williams paper probably won't win any awards for plain English but don't be fooled about just how important this pape........

The persistence of self-injury in relation to autism

by Paul Whiteley in Questioning Answers

Some behaviours associated with a diagnosis of autism don't make for great dinner table discussion. Self-injurious behaviours (SIBs), as exemplified by head banging, hair pulling and eye gouging must rank as some of the more distressing facets of [some] autism insofar as their potential effect on the person and also the people around them.These and other types of behaviour commonly headed under the category of so-called 'challenging behaviours' have tended not to be too evident when it come........

Around 1 in 5 with autism will experience seizure or seizure disorder

by Paul Whiteley in Questioning Answers

The paper by Jennifer Jaskiewicz and colleagues [1] recently offered a further important insight into the relationship between autism and seizure or seizure disorder (i.e. epilepsy).Based on the examination of records of nearly 50,000 children and young adults diagnosed with an autism spectrum disorder (ASD) compared with approximately quarter of a million 'not-autism' participants, authors reported some interesting trends. Concluding that some 19% of participants with autism experienced "s........ Read more »

Sex-specific immune response to Candida albicans in schizophrenia and beyond

by Paul Whiteley in Questioning Answers

I have quite a bit of time for the various members of the Stanley Division of Developmental Neurovirology at Johns Hopkins on this blog. Not least because of the interesting work of one researcher in particular - Emily Severance - as a name behind some potentially very important research on how food, infection and immune function might come together in complicated conditions such as [some] schizophrenia and [some] bipolar disorder (see here and see here).Continuing their 'gut-brain' theme (........

Add-on nutraceuticals for depression?

by Paul Whiteley in Questioning Answers

It came as no surprise to me that the systematic review and meta-analysis article by Jerome Sarris and colleagues [1] found what it did in relation to the use of [certain] adjunctive (add-on) nutraceuticals alongside antidepressants to reduce depressive symptoms: some of them might actually be clinically useful.With no medical or clinical advice given or intended, the authors report that "adjunctive use of SAMe, methylfolate, omega-3, and vitamin D with antidepressants" might be something to con........

On the question of valproate use and pregnancy

by Paul Whiteley in Questioning Answers

I very much want to stress the point that 'no medical or clinical advice is given or intended' on this blog before proceeding further with discussions based on the commentary paper by Richard Balon & Michelle Riba titled: 'Should Women of Childbearing Potential Be Prescribed Valproate?' [1].Valproate, as in preparations like sodium valproate, has been a particular talking point in recent years as a consequence of something of an emerging body of peer-reviewed science suggesting that its use ........

Brain GABA levels and autism meta-analysed

by Paul Whiteley in Questioning Answers

The paper by Remmelt Schür and colleagues [1] provides some (brief) blogging fodder today and the observation that following a "systematic literature review and meta-analysis of 1 H-MRS studies" brain GABA levels were found to be significantly lower in cases of autism spectrum disorder (ASD) than compared to control (not autism) populations.GABA - gamma-Aminobutyric acid - has been something of interest for quite a few years in autism research circles (see here). It's particular role ........ Read more »

Siblings of probands with autism: preferential screening suggested?

by Paul Whiteley in Questioning Answers

"Psychiatric and neurodevelopmental disorders cluster among siblings of probands with ASD [autism spectrum disorder]."That was the research bottom line presented in the paper by Elina Jokiranta-Olkoniemi and colleagues [1] who extracted data from the Finnish Prenatal Study of Autism and Autism Spectrum Disorders (FIPS-A). FIPS-A has been mentioned previously on this blog (see here) but this time around the aim was to look not at the various risk factors potentially associated........ Read more »

Immigrant background and risk of offspring ADHD

by Paul Whiteley in Questioning Answers

"The likelihood of being diagnosed with ADHD [attention-deficit hyperactivity disorder] was significantly increased among children of two immigrant parents... and children of an immigrant father."So said the findings published by Venla Lehti and colleagues [1] continuing a research theme from this authorship group (see here) on how immigration might, for various reasons, bring about an increased or decreased risk of certain behavioural and/or psychiatric outcomes.

More [metabolomic] evidence for dysbiosis and some autism?

by Paul Whiteley in Questioning Answers

The paper by Xiyue Xiong and colleagues [1] (open-access available here) took my attention recently and some further evidence contributory to the idea that the trillions of wee beasties that call our gastrointestinal (GI) tract home - collectively known as the gut microbiome - might have some important links to at least 'some' autism.Describing the results of "a GC/MS based metabolomic approach"  - GC-MS being gas chromatography-mass spectrometry and metabolomic(s) being the analysis o........

On autism symptoms in ADHD (again)

by Paul Whiteley in Questioning Answers

Continuing a research theme (see here), the paper by Jessica Green and colleagues [1] again focuses the spotlight on how the various childhood developmental diagnoses often enjoy mingling together when it comes to their real-life presentation; real ESSENCE in action. Such overlaps can and do present challenges to diagnosticians to unpick often complicated presentations (no, your 'Am I autistic?' screen is not really a good idea) and onwards the best way forward to manage symptoms ........

Autism and the [different] expression of pain

by Paul Whiteley in Questioning Answers

Two papers provide some brief discussion today. The first by Janice Goldschmidt [1] titled: 'What Happened to Paul? Manifestation of Abnormal Pain Response for Individuals With Autism Spectrum Disorder' provides an account of a young man with autism who during a "pilot nutrition intervention designed to teach cooking skills to young adults with autism spectrum disorder (ASD)" fell quite seriously. We are told that: "After his accident, which resulted in broken and dislocated bones in his ankle, ........ Read more »

Shared genetics? Autism, gastrointestinal issues and serotonin

by Paul Whiteley in Questioning Answers

I note the paper by Kara Gross Margolis and colleagues [1] (open-access available here) has been garnering a few media headlines with the suggestion that: "Gastrointestinal [GI] problems in autistic children may be linked to the same genetic mutations that cause other characteristics of autism spectrum disorder."The study, focusing on the idea that SERT (the serotonin transporter) encoded by the SLC6A4 gene might show some connection to 'some' autism [2], looked to model........

Vitamin D and autism: the story so far...

by Paul Whiteley in Questioning Answers

I don't want to keep you too long today aside from directing you to the literature review by Hajar Mazahery and colleagues [1] (open-access available here) discussing the collected peer-review literature on the topic of vitamin D and autism to date.Anyone that stops by this blog might already know about my interest in the science around this issue (see here and see here for example) and how quite a few more resources really should be directed into this 'sunshine' research area.

What does a gluten-free diet do to the gut microbiome?

In answer to the question posed in the title of this post: "A GFD [gluten-free diet] changes the gut microbiome composition and alters the activity of microbial pathways."So said the findings reported by Marc Jan Bonder and colleagues [1] (open-access) who presented results based on the "changes in the gut microbiomes of 21 healthy volunteers who followed a GFD for four weeks."

Water, carbamazepine and mother-embryo transmission

by Paul Whiteley in Questioning Answers

"These results provide the first evidence that carbamazepine in drinking water and at typical environmental concentrations is transmitted from mother to embryo."So said the findings reported by Gaurav Kaushik and colleagues [1] who continued a research theme looking at the possibility of an environmental 'exposome' also potentially overlapping with [some] autism (see here). The autism connection came from the a paper by Thomas & Klaper [2] who previously reported that putting fish in a ........ Read more »

The darker side to swimming with dolphins?

by Paul Whiteley in Questioning Answers

Described under the heading of a 'Challenging Case', the paper by Randall Phelps and colleagues [1] titled 'The Curse of the Dolphins: Cognitive Decline and Psychosis' highlights an intriguing case report potentially suggestive of a darker side to the idea of swimming with dolphins.Yes, you did hear me right - dolphins - those aquatic mammals regarded as one of the earth's most intelligent creatures and the suggestion that swimming with them might somehow 'impact' on aspects of a person's functi........

Autism prevalence in the Somali population in Minneapolis continued

by Paul Whiteley in Questioning Answers

A very quick post today to direct you to the paper by Amy Hewitt and colleagues [1] who seem to have finally published their findings on autism prevalence in the Somali population in Minneapolis in the peer-reviewed domain. I had previously covered their report on this blog (see here) and the suggestion that: "Somali (1 in 32) and White (1 in 36) children were about equally likely to be identified with ASD [autism spectrum disorder], but more likely to be identified with ASD than Black and ........

NAC for 'social impairment' in youth with autism... probably not

by Paul Whiteley in Questioning Answers

"The results of this trial indicate that NAC [N-acetylcysteine]  treatment was well tolerated, had the expected effect of boosting GSH [glutathione] production, but had no significant impact on social impairment in youth with ASD [autism spectrum disorder]."So said the results reported by Logan Wink and colleagues [1] (open-access) who, continuing an autism research theme, looked at whether this important L-cysteine prodrug might have more to give when it comes to a........
