Psychologists investigate a major, ignored reason for our lack of sleep - bedtime procrastination

by Christian Jarrett in BPS Research Digest

Short term, lack of sleep scrambles our mental functioning. Long term, the health consequences can be dire. What's stopping us from getting enough?For many, adequate sleep is elusive because of sleep disorders, including varieties of insomnia. For others there are practical challenges - baby care or night shifts, for example. A new study focuses on another major, yet strangely overlooked, reason - bedtime procrastination. You want to go to bed early. You know you need to get to bed. And yet you ........ Read more »

Restricted and repetitive behaviours disappeared? More optimal outcome and autism

by Paul Whiteley in Questioning Answers

Today I'm bringing to your attention the paper by Eva Troyb and colleagues [1] and the quite dramatic assertion: "Reports of current behavior indicated that RRB's [restricted and repetitive behaviors] had almost totally disappeared in the OO [optimal outcomes] group". RRBs just in case you might not know include quite an array of behaviours, some of which might not be considered 'disabling' such as the presence of certain circumscribed interests. Others, such as an insistence........ Read more »

The Evidence from Skull Measurements

by teofilo in Gambler's House

So far in this series of posts on “tracing the connections” between ancient Pueblo sites like Chaco Canyon and modern Pueblos, I’ve discussed evidence from linguistics and folklore, but of course if the issue is determining which modern groups are physically descended from which ancient ones it’s hard to beat evidence from actual physical remains.

This happens many times every day. A patient falls and may have hit her head, but there is no change from her normal mental status. To complicate matter, she takes an anticoagulant.

There are no clear signs of serious trauma. so should we automatically go to the trauma center?

Serious Restrictive Eating Disorders Occur at Any Weight

by Tetyana in Science of Eating Disorders


Although the words “anorexia nervosa” typically conjure up images of emaciated bodies, eating disorders characterized by dietary restriction or weight loss can — and do — occur at any weight. However, precisely because anorexia nervosa is associated with underweight, doctors are less likely to identify eating disorders among individuals who are in the so-called “normal” or above normal weight range, even if they have........

Twitter Psychosis as a Cultural Artifact

by The Neurocritic in The Neurocritic

The creation of the category “Twitter Psychosis" tells us more about the culture of contemporary psychiatry than it does about the purported dangers of social media overuse. Can Twitter really “cause” psychotic symptoms in predisposed individuals? Or is Twitter merely the latest technical innovation that influences “the form, origin and content of delusional beliefs” (Bell et al., 2005)? Twitter as the new telephone tower, radio waves, microchip implant or personal TV show, if you wil........ Read more »

Tough Talking Apes

by Mark E. Lasbury in The 'Scope

The new Planet of the Apes movie has talking apes! In the old Charleton Heston versions, the apes had thousands of years to evolve speech capabilities, but Dawn of the Planet of the Apes takes place only 10 years after their escape from the lab. Anatomical differences between human and ape hyoid position, rib musculature and tongue show us why speech is not possible for Cesar and his friends. In addition, new research points out the importance of the foxp2 protein for speech and auditory functio........ Read more »

by Erin Campbell in HighMag Blog

Do you ever feel nostalgic for a specific paper? Maybe this paper inspired your own research, or maybe it was a paper you immediately knew would be game-changing. Maybe, like today’s TBT paper, it was a great paper about solidly executed research with a memorable giggle-inducing technique. Thanks to a nostalgic HighMag reader and friend, Omar Quintero, we are being re-introduced to gonad sandwiches. In mammals, sex determination refers to the changes during early development that lead ........

The voices heard by people with schizophrenia are friendlier in India and Africa, than in the US

by Christian Jarrett in BPS Research Digest

When a patient with schizophrenia hears voices in their head, is the experience shaped by the culture they live in? Tanya Luhrmann and her colleagues investigated by interviewing twenty people diagnosed with schizophrenia living in San Mateo, California; twenty in Accra, Ghana; and twenty others in Chennai India. There were similarities across cultures, including descriptions of good and bad voices, but also striking differences.In San Mateo the interviewees talked about their condition as a bra........

Dipeptidyl peptidase (DPP) IV and autism: supporting opioid-excess?

by Paul Whiteley in Questioning Answers

Serum levels of dipeptidyl peptidase (DPP) IV were found to be lower in children with autism compared to asymptomatic controls according to the study by Shahid Bashira & Laila AL-Ayadhi [1]. Based on analysis by ELISA, researchers concluded that "alterations in the plasma level of DPP IV play a role in the pathophysiology of autism".A sailor went to sea, sea, sea... @ Wikipedia Anyone who has followed the autism research scene for any length of time might have already heard ab........

SCIENCE IN THE NEWS: THE 2014 EBOLA OUTBREAK

by Emily Lawson in Antisense Science

If you’ve been watching the news recently, you’ll probably have seen reports on the Ebola outbreak in West Africa. Around 673 people in Guinea and Liberia have died so far (including one case of a Liberian government employee who died shortly after arriving at Lagos airport in Nigeria), making this the most deadly outbreak to date. So what exactly is Ebola, and why is it so deadly?

Ebola virus disease (EVD) has an incredibly high mortality rate – while the current outbreak h........ Read more »

Violent Death Rates Increased After Traumatic Brain Injury

by William Yates, M.D. in Brain Posts

Anecdotal reports have linked traumatic brain injury with later violent death including death by suicide.Few large epidemiological studies have been published on this association.However, a recent Swedish population study published in JAMA Psychiatry provides valuable insight into this issue.Seena Fazel and colleagues from the University of Oxford, University College London and the Karolinksa Institute examined a large database of over 200,000 patients with TBI.Cases of TBI were identified from ........
