Researchers recently announced the discovery of a new species of ghost shark, Hydrolagus erithacus. Ghost sharks - which aren’t actually sharks but instead their closest living relatives - are an extraordinarily rare sighting. Actually, it was just a few months ago, when a ghost shark was filmed...

History of bipolar disorder = elevated risk of dementia: is vitamin D important?

by Paul Whiteley in Questioning Answers

"History of BD [bipolar disorder] is associated with significantly higher risk of dementia in older adults."So said the systematic review and meta-analysis published by Breno Diniz and colleagues [1] taking in the accumulated peer-reviewed literature on this topic. Including data for some 3000 individuals diagnosed with bipolar disorder and nearly 200,000 controls (without bipolar disorder), authors calculated something of a significantly higher risk of dementia in those with a do........

Do twitter or facebook activity influence scientific impact?

by Richard Kunert in Brain's Idea

Are scientists smart when they promote their work on social media? Isn’t this a waste of time, time which could better be spent in the lab running experiments? No. An analysis of all available articles published by PLoS journals suggests otherwise. My own twitter activity might best be thought of as learning about science (in […]... Read more »

Neuropsychiatric disorder onset "temporally related to prior vaccinations"?

"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........

The Science of the Rorschach Blots

by Neuroskeptic in Neuroskeptic_Discover

When the psychiatrist Hermann Rorschach blotted ink onto paper to produce a series of abstract patterns, could he have known that nearly 100 years later, the Rorschach test would be a household name?



Although the use of the Rorschach to diagnose mental illness is mostly a thing of the past, research on the test continues. Last week, two new papers were published on the Rorschach blots, including a fractal analysis of the images themselves and a brain scanning study using fMRI.

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........

Using Discourse Analysis to Assess Cognitive Decline

by The Neurocritic in The Neurocritic

Figure from Gauthier et al. (2005).

Alzheimer's Disease (AD) and other dementias are progressive neurodegenerative conditions that unfold over time. Subtle symptoms such as forgetfulness and word finding problems may progress to mild cognitive impairment (MCI), and then escalate to full-blown dementia. Recent efforts to classify prodromal states have included automated analysis of spontaneous... Read more »

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........

The Fantasy of Connecting Two Spinal Cords

by Neuroskeptic in Neuroskeptic_Discover

A peculiar new paper proposes the idea of "connecting two spinal cords as a way of sharing information between two brains". The author is Portuguese psychiatrist Amílcar Silva-dos-Santos and the paper appears in Frontiers in Psychology.



Frontiers are a publisher with a troubled history of publishing dubious science. But this paper is unusual, even by Frontiers' standards, because it contains virtually no science at all.

In a nutshell, Silva-Dos-Santos suggests that it would be interest... Read more »

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........

"Dominance" Training Deprives Dogs of Positive Experiences

by CAPB in Companion Animal Psychology Blog

Dominance is an outdated approach to dog training – and it also means dogs miss out on fun.Approaches to dog training based on dominance rely on the idea that you have to be the ‘alpha’ or pack leader. Unfortunately, this type of dog training is not just out-of-date and potentially risky, but modern approaches to dog training are also a lot more fun – for you and the dog.What is dominance in dog training?We sometimes hear the phrase ‘my dog is being dominant.’ ‘Your dog is being do........
