Bowel issues in autism may cluster with other symptoms

by Paul Whiteley in Questioning Answers

"Clinicians should be aware that gastrointestinal problems, anxiety, and autonomic dysfunction may cluster in children with ASD [autism spectrum disorder] and should be addressed in a multidisciplinary treatment plan."So said the findings by Bradley Ferguson and colleagues [1] who, continuing an autism research theme (see here), "examined the relationship between gastrointestinal symptomatology, examining upper and lower gastrointestinal tract symptomatology separately, and autonomic n........

Expanding MAR autism

by Paul Whiteley in Questioning Answers

MAR autism - maternal autoantibody-related autism - is a term that has graced this blog before (see here). Describing a state where autoantibodies directed against foetal brain proteins have been detected in some mothers who have children diagnosed with an autism spectrum disorder (ASD), the suggestion is that such evidence further substantiates a role for various maternal immune functions and processes when it comes to offspring risk of at least some types of autism.Although interesting, t........

Project TENDR and chemical exposures

by Paul Whiteley in Questioning Answers

Yes, I know I'm writing on a Sunday again, but it will be a short-ish post I promise you. The reason for the entry is this brief communication [1] reporting: "The TENDR [Targeting Environmental Neuro-Developmental Risks] authors agree that widespread exposures to toxic chemicals in our air, water, food, soil, and consumer products can increase the risks for cognitive, behavioral, or social impairment, as well as specific neurodevelopmental disorders such as autism and attention deficit........

Pregnancy paracetamol use and "autism spectrum symptoms" (again)

by Paul Whiteley in Questioning Answers

Continuing something of a research theme whereby pregnancy paracetamol (acetaminophen) use has been *correlated* with a few offspring developmental outcomes (see here and see here), the paper by Claudia Avella-Garcia and colleagues [1] (open-access available here) makes for some blogging fodder today.Including data from some 2,600 mother-child pairs living in Spain, researchers prospectively gathered data on maternal paracetamol use ("never, sporadic, persistent") during pregnancy alongside deve........

Cow's milk allergy and risk of psychiatric disorder

by Paul Whiteley in Questioning Answers

"Psychiatric disorders are frequent and severe in pre-school children with cow's milk allergy."That research 'bottom line' reported by Topal and colleagues [1] looking at the possibility of behavioural correlations accompanying an immune response to milk caught my eye recently. Building on the idea that atopic or allergic disease might elevate the risk of various behavioural outcomes (see here) or vice-versa, researchers set about comparing rates of various behavioural conditions using the "Earl........

Ehlers-Danlos syndrome (EDS) associated with autism?

by Paul Whiteley in Questioning Answers

Ehlers-Danlos syndrome (EDS) refers to a collection of conditions also headed under the label of connective tissue disorder. EDS affects the 'cellular glue' that basically gives biological tissues their shape and stability such as cartilage. There are various types of EDS and symptoms can vary from person-to-person but one of the most frequent characteristics of the syndrome is joint hypermobility.I've speculated a few times on this blog about the possibility that EDS and/or joint hypermobility ........

Pregnancy infection and offspring autism risk meta-analysed

by Paul Whiteley in Questioning Answers

Another day, another short post about a meta-analysis; this time based on the suggestion that maternal infection during the critical 'nine months that made us' might elevate the risk of offspring autism and reported on by Hai-yin Jiang and colleagues [1].Based on the collected analysis of 15 peer-reviewed studies covering some 40,000 people diagnosed with an autism spectrum disorder (ASD), the authors concluded that yes, "maternal infection during pregnancy was associated with an ........

Autism and asthma meta-analysed.. or is it?

by Paul Whiteley in Questioning Answers

"In conclusion, the results of this meta-analysis do not suggest an association between asthma and ASD [autism spectrum disorder]. Further prospective studies ascertaining the association between asthma and ASD are warranted."So said the results of the meta-analysis by Zhen Zheng and colleagues [1] (open-access available here) and with it some research that made me think a little. Think because, on more than one occasion, I've talked about research suggesting that there might be a link betw........ Read more »

Autism: visual stress and coloured overlays?

by Paul Whiteley in Questioning Answers

The small study from Amanda Ludlow & Arnold Wilkins [1] is introduced for your reading pleasure today and the idea that "atypical sensory behaviours and symptoms of visual stress" were not uncommon features when it came to a diagnosis of autism and/or Tourette's syndrome (TS). As per that opening sentence, this was a small study - 12 children with autism, 12 children with TS and 12 controls - but that doesn't mean that the results might not be important...So far you might be slightly un........

The gut microbiome and coeliac disease risk

by Paul Whiteley in Questioning Answers

"Elective caesarean delivery and repeated maternal urinary tract infections during pregnancy are associated with increased risk of CD [coeliac disease] onset during childhood, suggesting the role of dysbiosis during early life."Those were some of the rather surprising findings reported by Fredinah Namatovu and colleagues [1] (open-access) following their pretty well-powered study covering "1 912 204 children born between 1991 and 2009, 6 596 of whom developed CD before 15 years of........

Eosinophilic esophagitis (EoE): another over-represented condition in autism

by Paul Whiteley in Questioning Answers

Returning to the idea that not every symptom/characteristic present in cases of autism is necessarily 'due to autism' are the findings reported by Heifert and colleagues [1] and the observations that: "Children with ASD are more likely to be diagnosed with EoE [Eosinophilic esophagitis] compared to controls" and further: "A diagnosis of feeding disorder was strongly associated with EoE."EoE is something that has been discussed before on this blog in relation to the myriad of gastrointe........

Gestional exposure to Group B Streptococcus and an autism model

by Paul Whiteley in Questioning Answers

"Overall, these data show for the first time that gestational exposure to GBS [Group B Streptococcus] plays an important role in the generation of neurodevelopmental abnormalities reminiscent of human autism spectrum disorders (ASD)."I chose to discuss the findings reported by Marie-Julie Allard and colleagues [1] on this blog for various reasons. That this research team already have some research 'form' when it comes to looking at GBS [2] is one; another is the idea that they rep........ Read more »

Antipsychotic prescribing trends in autism meta-analysed

by Paul Whiteley in Questioning Answers

"Almost 1 in 10 antipsychotic-treated youth were diagnosed with ASD [autism spectrum disorder] and/or ID [intellectual disability], and 1 in 6 youth with ASD received antipsychotics."The findings reported by Su Young Park and colleagues [1] have not surprisingly garnered some media attention (see here).

An excess of ADHD among children born to glyphosate appliers?

by Paul Whiteley in Questioning Answers

The job of pesticide applicator is one that has been discussed on this blog before (see here). Minus any scaremongering, the conclusion of that post was that under certain circumstances (e.g. a high pesticide exposure event - HPEE), the effects of that particular occupation might be pretty far-reaching for the 'cognitive' as well as physical health of the individual concerned.Today I'm talking about other potential effects "needing confirmation by further studies" related to perhaps one of ........

Eating difficulties in adolescents with CFS/ME

by Paul Whiteley in Questioning Answers

I tread quite carefully when discussing the paper by Sarah Harris and colleagues [1] (open-access available here) on the potential causes and effects of 'eating difficulties' when it comes to adolescent chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME).Careful because (i) I don't want to confuse eating difficulties with eating disorder (they are not one and the same) and (ii) the suggestion that some of the young adults included for study "recognised how their eating difficulties were ........

HBOT and autism systematically reviewed

by Paul Whiteley in Questioning Answers

"Current evidence indicates that HBOT [Hyperbaric Oxygen Therapy] is not an effective treatment for children and youth with autism."That was the conclusion reached by Cynthia Goldfarb and colleagues [1] following their "systematic review of the literature evaluating the clinical impact of HBOT on behavior and development in ASD [autism spectrum disorder]." Drawing on guidance from the American Academy of Neurology and their "Classification of Recommendations", authors lo........ Read more »

Is autism underdiagnosed in prisoners? Probably not...

by Paul Whiteley in Questioning Answers

The UK media today is awash with the result of 'that referendum'.Life however goes on here at Questioning Answers and today the recent opinion piece by Sarah Ashworth [1] talking about autism being 'underdiagnosed' in the prison population provides the starting material for today's post.Being careful not to generalise nor also 'excusing' the often important reasons why people end up in prison, I'm particularly interested in this area of discussion given what is increasingly being recognised with........

ADHD symptoms improved with allergic rhinitis treatment

by Paul Whiteley in Questioning Answers

The findings reported by Ming-Tao Yang and colleagues [1] make for some brief blogging fodder today and the idea that: "Higher ADHD [attention-deficit hyperactivity disorder] scores in children with AR [allergic rhinitis] compared with healthy controls decreased significantly with AR treatment." Said AR treatment consisted of "nonpharmacologic intervention, oral antihistamines, and topical steroids."I know furrowed brows and eye-rolling might be the response of some people to........

Still 'nothing good comes from exposure to lead'

by Paul Whiteley in Questioning Answers

Consider this short-ish entry a sort of extension of other discussions on this blog on the topic of lead (Pb) (see here). As per the blog title, the systematic review published by Maryam Daneshparvar and colleagues [1] (open-access available here) adds to the quite voluminous peer-reviewed literature indicating that lead exposure, particularly during infancy and childhood, seems to be associated with nothing but adverse outcomes in terms of development and behaviour.Surveying the research litera........
