Neuropsychiatric disorder onset "temporally related to prior vaccinations"?

by Paul Whiteley in Questioning Answers

"Given the modest magnitude of these findings in contrast to the clear public health benefits of the timely administration of vaccines in preventing mortality and morbidity in childhood infectious diseases, we encourage families to maintain vaccination schedules according to CDC guidelines."The quote opening this post comes from the paper published by Douglas Leslie and colleagues [1] (open-access) and offers not a conclusion from their study looking at the possibility that "the onset of some ne........

Catatonic symptoms and autism

by Paul Whiteley in Questioning Answers

"Catatonic symptoms are more prevalent in young people with autism than previously thought" said the article recently published by Breen and Hare [1]. Continuing a research theme of at least one of the authors [2], the idea that catatonic symptoms - primarily manifesting as stupor, unresponsiveness to light, noise or touch, mutism, etc - might be over-represented when it comes to autism is not a new one by any means.Breen & Hare set about looking for "the presence and nature of such att........

Social interaction and autism: it takes two to tango

by Paul Whiteley in Questioning Answers

Psychology experiments are not generally fodder for this blog when it comes to autism. The main reason being that quite a few appearing in the peer-reviewed literature tend to look at quite abstract features perhaps somewhat removed from the daily lives of autistic people and their significant others. A few also seem to struggle with the idea that grand over-arching psychological theories (that seem to inevitably follow psychological findings in particular) are not required when it comes to auti........

Vitamin D halting colds and flu?

by Paul Whiteley in Questioning Answers

"Overall, the study said one person would be spared infection for every 33 taking vitamin D supplements. That is more effective than flu vaccination, which needs to treat 40 to prevent one case, although flu is far more serious than the common cold."That was some of the media interpretation of the paper - "systematic review and meta-analysis of individual participant data" - published by Adrian Martineau and colleagues [1] looking at the collected data on vitamin D supplementation "on risk ........

"early medical events are associated with clinical ASD phenotypes"

by Paul Whiteley in Questioning Answers

The paper by Charlotte Willfors and colleagues [1] (open-access) provides some food for thought today and the observation that various individual and cumulative medical events - "early medical events likely to be caused by environmental factors" - may be important to at least some autism.Researchers "scrutinized the early medical histories of a rare and informative sample of 13 MZ [monozygotic] twin pairs discordant for clinical ASD [autism spectrum disorder]" also including "13 M........

"Androgens were not associated with autistic traits at 12 months of age"

by Paul Whiteley in Questioning Answers

EARLI - the Early Autism Risk Longitudinal Investigation study - has been mentioned on this blog before (see here) with the aim of the initiative to "examine possible environmental risk factors for autism and study whether there is any interplay between environmental factors and genetic susceptibility."In this post I'm bringing the paper by Bo Park and colleagues [1] (open-access) to your attention and the observation(s) that umbilical cord blood levels of testosterone and other relate........

The Complexities of “The Love Hormone”

by Miss Behavior in The Scorpion and the Frog

New York street art. Photo inWikimedia Commons posted by Pedroalmovar.Oxytocin, commonly known as “the love hormone”, is a small chemical that is produced in the brain of mammals, but can both act as a neurotransmitter and enter the blood stream and act as a hormone. It has long been heralded for its role in both maternal and romantic love, but more recent research is showing us just how complicated the physiology of love can be.Oxytocin is released in mammalian mothers after birth. It promo........ Read more »

Relative age and ADHD medication

by Paul Whiteley in Questioning Answers

"Youngest children in class 'more likely to be given ADHD drugs'" went the NHS Choices headline that led me to the short report produced by Martin Whitely and colleagues [1] (open-access).ADHD - attention-deficit hyperactivity disorder - is something of interest to this blog; not least the idea that relative age (age relative to peers in the same school year group) might be an important variable when it comes to at least some diagnoses of the condition (see here).The Whitely paper draws on ........

Depression, SMILES and Modified Mediterranean diet (advice)

by Paul Whiteley in Questioning Answers

SMILES in the title of this post refers to the SMILES trial - Supporting the Modification of lifestyle In Lowered Emotional States - and results recently published by Felice Jacka and colleagues [1] (open-access) pertinent to the idea that "dietary improvement" might be something to consider when a diagnosis of major depressive episode (MDE) is received.Having previously published their study protocol [2], researchers set about looking at whether under "single blind, randomised controlled" ........

More than Meets the Eye

by Aurametrix team in Aurametrix Blog

Eyeglasses are almost as old as the civilization itself. They have not changed much since Benjamin Franklin's bifocals in the 18th century. Nor were they made obsolete by laser surgery and contacts. Still, eyeglass technology leaves much to be desired. But new technologies are unfolding before our eyes. ... Read more »

Pregnancy exposure to SSRIs and offspring autism risk: debate continues

by Paul Whiteley in Questioning Answers

"It remains unclear whether the association between first trimester SSRI [selective serotonin reuptake inhibitor] exposure and child autism that was present in the case-control studies even after adjustment for MMI [maternal mental illness] is a true association or a product of residual confounding."So said the results of the systematic review and meta-analysis undertaken by Hilary Brown and colleagues [1] looking at a potentially important association between pregnancy use of a class ........

A few-foods diet for ADHD: a systematic review of meta-analyses of double-blind, placebo-controlled trials

On dietary and nutritional therapies for ME/CFS

by Paul Whiteley in Questioning Answers

ME/CFS in case you don't already know refers to Myalgic Encephalomyelitis / Chronic Fatigue Syndrome and, according to the findings reported by Nadia Campagnolo and colleagues [1], is in need of quite a bit more scientific investigation when it comes to the application of dietary changes and nutritional supplements to potentially alter the course of the condition(s).Surveying the peer-reviewed literature "from 1994 to May 2016" the authors looked for peer-reviewed studies where "CFS/ME........

On atopic disease and ADHD: 'strong evidence' for an association

Natural course of "chronic disabling fatigue" in adolescents

by Paul Whiteley in Questioning Answers

"We use the term 'chronic disabling fatigue' (CDF) because CFS/ME [chronic fatigue syndrome / myalgic encephalomyelitis] was not verified by clinical diagnosis."That was one of the important details included in the findings reported by Tom Norris and colleagues [1] (open-access) who "aimed to describe the epidemiology and natural course of CFS/ME in adolescents aged 13–18 years."

ADHD, obesity and bariatric surgery?

by Paul Whiteley in Questioning Answers

"The findings suggest that a considerable number of patients before and after bariatric surgery screened positive for ADHD [attention-deficit hyperactivity disorder]. It can be hypothesized that some core ADHD symptoms improve after surgery."Bariatric surgery, where several surgical options are available to aid weight loss in those who present with 'dangerous' obesity, was the topic of the paper by Nielsen and colleagues [1] (open-access available here) who set out to compare "pre- and........

Brain Shape and Personality Type

by William Yates, M.D. in Brain Posts

Personality has often been conceptualized a a human feature shaped largely by nurture and environment.Unlike major neuroscience medicine disorders, personality features have been considered less influenced by brain structure and genetic influences.A recent brain structure (morphology) study puts these assumptions at risk.Roberta Riccelli along with colleagues in Italy and Florida State University studied brain structural features across 507 participants in the Human Connectome Project.All subjec........

"Schizophrenia confers a high endogenous risk for diabetes"

"Schizophrenia confers a high endogenous risk for diabetes, and the risk is further increased by both first-generation and second-generation antipsychotics."So concluded Anto Rajkumar and colleagues [1] who relied on participant data in the thousands derived from several of those very helpful Scandinavian population registries (this time in Denmark) to add some further science to the idea that psychiatric diagnoses like schizophrenia seem to carry an elevated risk for all-manner of somatic ........
