"After adjustment for several confounders, longer duration of breastfeeding was independently associated with better cognitive development and with fewer autistic traits."So said the paper by Olivier Boucher and colleagues  communicating findings based on the examination of data from "the INMA Project, a Spanish multicenter birth-cohort study" (an initiative that has cropped up on this blog before).Including over 1300 children who were subject to a battery of psychometric and behavioural asse........

Children’s beliefs about animal welfare and sentience are linked to their own experiences with animals.Surprisingly little is known about children’s beliefs and knowledge about animals. Yet this information could help to improve humane education programs for children. Two recent studies begin to fill this gap, with recommendations for how humane education is taught.We know from previous research that even very young children like animals, and that children with pets are more likely to attrib........

Apolipoprotein A5 gene (APOA5) is one of the genes implicated in contributing to a predisposition for hypertriacylglycerolaemia (HTG), a complex polygenic pathology that is highly influenced by environment. Hypertriacylglycerolaemia is characterized by having high circulating triacylglycerol levels and is a significant risk factor for cardiovascular disease and atherosclerosis. This genetic predisposition has an inherited component (based on polymorphisms) as well as an acquired component regu........ Read more »

"This study does not support the hypothesis that MPH [methylphenidate] increases risk of incident psychotic events. It does indicate an increased risk of psychotic events before the first prescription of MPH, which may be because of an association between psychotic events and the behavioural and attentional symptoms that led to psychiatric assessment and initiation of MPH treatment."The results published by Man and colleagues  (open-access) sit right with me. I say that on the basis........ Read more »

Franz Joseph Gall (1758-1828), a founding father of phrenology
Phrenology was the pseudoscience of identifying a person's character and mental abilities on the basis of skull morphology (“bumps on the head”). The enterprise was based on four assumptions (Gross, 2009):
intellectual abilities and personality traits are differentially developed in each individual
these abilities and traits

Parkinson's disease (PD) is a progressive neurodegerative disorder estimated to affect 7 to 10 million individual worldwide.The primary mechanism for Parkinson's disease is a reduction in the neurotransmitter dopamine in the midbrain region of the substantia nigra highlighted in red in the figure.PD impairs motor and cognitive functions and leads to significant decline in psychosocial functioning.Drugs for PD can be effective in reversing and slowing the progression of the illness.

Are the eyes the windows to intelligence? In an interesting paper, Georgia psychologists Jason S. Tsukahara and colleagues report that there's a positive correlation between pupil size and cognitive ability.
It's well known that our pupil size varies over time due to changes in both emotional state and cognitive 'effort'. As Tsukahara et al. put it
Starting in the 1960s it became apparent to psychologists that the size of the pupil is related to more than just the amount of light enterin... Read more »

The results published by Robert Joseph and colleagues  provide some blogging fodder today, observing that as part of the ELGAN (Extremely Low Gestational Age Newborns) Research Study, gestational age might matter when it comes to offspring risk of autism spectrum disorder (ASD).Gestational age is a measure of how far along a pregnancy is but in the context of the Joseph study refers to premature birth or those "born at least 3 months early."

It does not come as a surprise that background music in a café helps create the ambience and affects how much customers enjoy sipping their cappuccinos. But recent research suggests that the choice of lyrics can even impact the social behavior of customers.

I don’t mean to brag, but I’ve got irritable bowel syndrome, says a character of a sitcom.

Follicular lymphoma is a B-cell lymphoma that remains incurable with conventional therapies. Ying et al. (2016) present a new study exploring the biological and genetic features of follicular lymphoma and identifying potential new therapeutic targets. The authors identified recurrent mutations in the mTOR regulator RRAGC, a small G-protein, in approximately 10% of follicular lymphoma cases. Mutations in RRAGC localized to one protein surface area surrounding the GTP/GDP–binding sites. In s........ Read more »

Consider this short blog post an extension of some previous discussions (see here and see here) on a rather peculiar 'association' between urinary tract infections (UTIs) and psychosis. UTIs basically refer to an infection in any part of the urinary system (kidneys, bladder, etc) typically treated with antibiotics. Psychosis is a state that causes a person to perceive or interpret things around them in an atypical way, usually accompanied by delusions or hallucinations. For a while now........ Read more »

Is your dog a natural athlete or a couch pup-tato? The answer might depend on how far removed it is from its wild ancestors. Dogs that are more similar to wolves have kept more of their natural athleticism, while breeding has rendered other types of dogs a little...less impressive.
