8:44 AM | DSM-5 impacting on autism numbers
"Consistent with previous reviews, the majority of included studies indicated between 50 and 75 % of individuals will maintain diagnoses."That was one of the conclusions reached by Isaac Smith and colleagues [1] following their systematic review of studies comparing DSM-IV and DSM-5 criteria for autism spectrum disorder (ASD) and what the changes mean for eligibility for the label.Authors further reported that: "the greatest decreases [were] among high-functioning populations with IQs over […]

5:46 AM | Does maternal asthma 'prime' for offspring neurodevelopmental disorder?
The paper from Jared Schwartzer and colleagues [1] (open-access) including a couple of familiar names on the authorship list (Charity Onore and Paul Ashwood) caught my attention recently. Based on mouse studies and the artificial induction of maternal allergy/asthma in pregnant mice, researchers reported that: "Activation of the maternal immune system with an allergy/asthma insult significantly perturbed developmental growth and species-typical behaviors in offspring." Further that […]

8:39 AM | MMR vaccine was not associated with increased risk of autism
"In this large sample of privately insured children with older siblings, receipt of the MMR [measles-mumps-rubella] vaccine was not associated with increased risk of ASD [autism spectrum disorder], regardless of whether older siblings had ASD. These findings indicate no harmful association between MMR vaccine receipt and ASD even among children already at higher risk for ASD."That was the conclusion reached in the study by Anjali Jain and colleagues [1] (open-access) based […]

8:31 AM | Jessica Biesiekierski on non-coeliac gluten sensitivity (NCGS)
It's not often that I dedicate a blog post to a specific individual and their views and opinions on a particular topic. Today however, I'm doing just that to provide you with a link to the paper from Jessica Biesiekierski on the topic of non-coeliac gluten sensitivity (NCGS) [1] (open-access).The reason? Well, aside from being one of the primary protagonists in the research topic of gluten-related ills outside of the autoimmune condition known as coeliac (celiac) disease (itself the […]

8:51 AM | Tics are common in adults with autism
The title of this post comes from a quote included in the paper by Ursula Kahl and colleagues [1] based on their study of the "phenomenology and characteristics" of tics in adults diagnosed with an autism spectrum disorder (ASD) compared with a small control group of adults with Gilles de la Tourette syndrome (GTS). A tic by the way, is a "sudden, fast, repeated movement or sound."This is not the first time that tics have been examined with the autism spectrum in mind. The paper from […]

"To conclude, the presentation of ALTs [autistic-like traits/symptoms] at the sub-threshold or threshold level may be closely associated with BPD [bipolar disorder] and SZ [schizophrenia]."That was the conclusion reached in the paper by Junko Matsuo and colleagues [1] (open-access here) based on their analysis of nearly 300 adults aged between 25-59 years including those diagnosed with "MDD [major depressive disorder], n=125; bipolar disorder, n=56; […]

7:52 AM | Higher cancer mortality rates associated with mental illness
The findings reported by Steve Kisely and colleagues [1] were of some interest recently and their assertion that despite cancer incidence being "the same as the general population for most psychiatric disorders" or even slightly reduced when a diagnosis of schizophrenia was for example received, mortality due to cancer was "increased in psychiatric patients."Such findings were based on their examination of: "Mental health records [that] were linked with cancer registrations and death […]

8:08 AM | Immune signature in ME/CFS detected in cerebrospinal fluid
The research tag-team that is Mady Hornig and Ian Lipkin are fairly frequently mentioned on this blog. If it's not to do with their studies in autism research (see here for a recent mention) it is with their ground-breaking work looking at chronic fatigue syndrome / myalgic encephalomyelitis (CFS/ME) in mind (see here for example).Indeed their latest paper [1] extends some recent findings (see here) on immune involvement in relation to CFS/ME [2] with a focus on examinations in cerebrospinal […]

5:38 AM | Interoception and body awareness in autism
"Interoception: the sense of the physiological condition of the body" [1].This was an important concept detailed in the paper by Lisa Fiene and Charlotte Brownlow [2] with autism in mind. Looking at how adults diagnosed with an ASD (autism spectrum disorder) "interpret elements of the interoceptive sense, which includes thirst, hunger, temperature, satiety" researchers questioned those on the spectrum (n=74) and asymptomatic controls (n=228) with "self-reported perceptions of body […]

7:31 AM | Effects of prenatal organophosphate pesticide exposure on a mouse model of autism
Pesticides and autism is a topic previously covered on this blog (see here for example). The idea that some of the various preparations that we use to control the pests which have an ability to blight our crops or cause serious health issues could be linked to an increased risk of autism is an area likely to invoke some divisions within elements of the autism and wider scientific community.Part of the problem with the available evidence suggesting a link between autism and pesticide exposure is […]

5:34 AM | Cleanrooms and autism?
The paper by Scott Faber and colleagues [1] (open-access) is the topic of today's post and the idea that a cleanroom sleeping environment might impact on some important issues accompanying at least some autism.Just in case you hadn't come across the concept of a cleanroom, the concept is that a space is provided where various systems are put in place to control environmental pollutants such as dust, microbes and various chemical emissions. More readily associated with the construction of […]
