"Among adult patients with epilepsy of unknown etiology, a significant minority had detectable serum Abs [autoantibodies] suggesting an autoimmune etiology."So said the findings reported by Divyanshu Dubey and colleagues  continuing a research theme previously discussed on this blog (see here) on how epilepsy / seizure-type disorder(s) for some might have more to do with immune function than many people might think.OK, a brief bit of background: epilepsy is a blanket term cover........

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 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  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........

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?

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 are more prevalent in young people with autism than previously thought" said the article recently published by Breen and Hare . Continuing a research theme of at least one of the authors , 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........

Alzheimer's Disease (AD) and other dementias are progressive neurodegenerative conditions that unfold over time.

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........

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 »
