Autoimmune disease(s) and ADHD: birds of a feather?

by Paul Whiteley in Questioning Answers

"A personal history and a maternal history of autoimmune disease were associated with an increased risk of ADHD [attention-deficit hyperactivity disorder]. The previously reported association between type 1 diabetes and ADHD was confirmed. In addition, specific parental autoimmune diseases were associated with ADHD in offspring."So said the study results published by Nielsen and colleagues [1] including "a study population of 983,680 individuals followed from 1995 to 2012." Reliant once aga........ Read more »

CHL1 Hypermethylation in Breast Cancer

by Esperanza Martín Sánchez in EpiBeat

Breast cancer (BC) is the most common cancer among women and one of the leading causes of cancer-related deaths worldwide (1-3). It is a clinically heterogeneous disease, with at least 5 different subtypes (4) and quite variable prognosis, even within a subtype. In spite of early detection programmes, unfortunately 20-30% of early stage cases will eventually experience recurrence and develop distant metastasis. However, currently, there is no acceptable method for monitoring patients who are lik........ Read more »

The extra-intestinal effects of coeliac disease autoimmunity?

by Paul Whiteley in Questioning Answers

"In 3.5-year-old children, CDA [coeliac disease autoimmunity] is associated with increased reports of child depression and anxiety, aggressive behavior, and sleep problems when mothers are unaware of their child’s CDA status."So said the findings reported by Laura Smith and colleagues [1] (open-access available here) adding to an emerging body of peer-reviewed research suggesting that the archetypal 'gluten is the baddie' autoimmune condition known as coeliac disease might, when not manag........

Depression in parents of children with autism

by Paul Whiteley in Questioning Answers

"Mothers (OR 2.95, 95% CI 2.81-3.09) and fathers (OR 2.41, 95% CI 2.25-2.58) of children with ASD [autism spectrum disorder] were more likely to have a diagnosis of depression than parents of children without ASD."The paper by Cohrs and Leslie [1] is probably not going to win any awards for novelty when it comes to their findings that: "Autism Spectrum Disorder (ASD) in children can have secondary effects on the child's parents." It does however represent another important piece of evidence........ Read more »

Mitochondria support for mitochondrial activity in [some] autism

Spontaneous Pneumothorax and air travel in BHD Syndrome

by Joana Guedes in BHD Research Blog

Previous studies show that BHD syndrome causes spontaneous pneumothorax (SP) in 24-38% of patients, with a recurrence rate of up to 75% (Toro et al., 2007; Toro et al., 2008; Houweling et al., 2011). A common preventative strategy used following an initial SP in patients with BHD is pleurodesis, however, its efficacy in preventing recurrent episodes is not well known. Due to the pressure changes during air travel, cystic air spaces expand and compress in the thorax possibly leading to cyst ruptu........ Read more »

I would walk 500 miles... or maybe just 8 miles (a day).

by Paul Whiteley in Questioning Answers

"Desk-bound workers should ‘walk EIGHT miles a day’ to slash risk of heart attacks or stroke" went one headline talking about the findings reported by William Tigbe and colleagues [1]. Drawing on data from over 110 postal workers - "(55 office-workers, 5 women, and 56 walking/delivery-workers, 10 women)" - who wore "activPAL physical activity monitors for seven days", researchers observed some potentially important trends.Alongside wearing their activity monitors, participants were also asse........

Getting High Off Snakebites?

by Neuroskeptic in Neuroskeptic_Discover

In a curious case report, Indian psychiatrists Lekhansh Shukla and colleagues describe a young man who said he regularly got high by being bitten by a snake.



The 21-year old patient sought treatment for his heavy drug abuse, which included heroin and marijuna. He also reported a less conventional habit: he visited a local snake charmer, where he was bitten on the lips by a "cobra" in order to get high:
He reported that his peers and the snake charmer informed him that he would have drows... Read more »

This Is How Vision, Not Limbs, May Have Driven Fish onto Land

by beredim in Strange Animals






In a recent study, researchers provide a new theory for the reason we walk the Earth




A new provocative study suggests it was the power of the eyes and not the limbs that first led our ancient aquatic ancestors to make the momentous leap from water to land. According to it, crocodile-like animals first saw easy meals on land and consequently evolved limbs that enabled them to get there, ... Read more »

"Relatives of individuals with ASD were at higher risk of ADHD"

by Paul Whiteley in Questioning Answers

"Individuals with ASD [autism spectrum disorder] and their relatives are at increased risk of ADHD [attention-deficit hyperactivity disorder]."So said the paper published by Laura Ghirardi and colleagues [1] (open-access) who studied "1 899 654 individuals born in Sweden between 1987 and 2006" and identified some 28,000 cases of ASD and 82,000 cases of ADHD "with 13 793 individuals... being comorbid cases."Results: "Individuals with ASD were at higher risk of having ADHD, co........

Epigenetic Predisposition to Radiation Fibrosis

by Christoph Weigel in EpiBeat

Radiotherapy is a highly efficient treatment for many cancers including breast cancer. Intraoperative radiotherapy (IORT), a relatively new type of radiation therapy, has proven successful as a curative treatment for early cancer stages. However, in spite of great improvements in dose delivery and imaging technology, unwanted exposure of healthy tissue to radiation cannot be fully avoided. The resulting late-onset toxicity due to the exposure of health tissue currently limits the usefulness of r........ Read more »

Blocking FRAAs and thyroid function in autism (continued)

by Paul Whiteley in Questioning Answers

Readers of this post are advised to check out a previous blogging occasion describing how 'FRAAs - folate receptor alpha autoantibodies - may correlate with reduced thyroid function in cases of autism' before heading into this entry on the recent paper published by Richard Frye and colleagues [1].You're back already? OK, well just in case you didn't read that last entry (😉), it's worthwhile first noting that: "Folate receptor α (FRα) autoantibodies (FRAAs) are prevalent in autism spectrum d........ Read more »

The growing divide between higher and low impact scientific journals

by Richard Kunert in Brain's Idea

"Logical fallacies in animal model research"

by Paul Whiteley in Questioning Answers

A paper which is a bit 'out of left field' is presented for your reading pleasure today and how one should be rather careful about how animal research - "with focus on animal models of mental illness" - is translated into relevance to humans [1].The paper by Espen Sjoberg is pertinent to various diagnostic labels including depression and schizophrenia. I would perhaps disagree with the author including autism under the specific heading of 'mental illness' (bearing in mind various mental hea........ Read more »

Fatigue in adults with a 22q11.2 deletion syndrome

by Paul Whiteley in Questioning Answers

The genetic condition called 22q11.2 deletion syndrome (22q11.2DS) has, on occasion, provided some research fodder for this blog (see here and see here). The reason for its inclusion here has tended to be around the 'overlap' in the presentation of 22q11.2 and autism/autistic features and the importance of appropriate screening as and when an autism diagnosis is received (see here). Remember: receipt of an autism diagnosis is a starting point not the finishing line.Today I'm once again talk........ Read more »
