Taking the popular over-the-counter pain and fever medication paracetamol during pregnancy might affect the unborn child more than we assumed – and hoped for. Recently, research began to link pre-natal exposure of paracetamol (also known as acetominophen) to asthma and poor motor and communication skills in small children. Now, a new study published yesterday suggests that taking paracetamol during pregnancy comes with an increased risk for the baby of developing attention deficit hyperactivity disorder (ADHD) later.
The authors of this study investigated 64,322 Danish children (born 1996-2002) and their mothers. The women were asked whether they have taken paracetamol in computer-assisted telephone interviews three times during their pregnancy and shortly after. To asses ADHD in children, the researchers used different ways: they asked the mothers of 7-year-olds about their child’s behaviour using a standardised ADHD questionnaire. Moreover, they used Danish medical registries to gain information about diagnoses of hyperkinetic disorder, which resembles a severe form of ADHD, and descriptions of ADHD medication to the children.
The first systematic study investigating the effects of caffeine on human performance – sponsored by Coca-Cola – has been published about 100 years ago. Since then, thousands of other studies have been looking at if and in which ways caffeine improves cognitive performance. This question is still debated in science, but there is general consensus that caffeine can be seen as an enhancer for specific functions like mood, attention, concentration and reaction time. These enhancement effects have been shown in studies with the general set-up that participants first took caffeine and then did a performance task. This matches our everyday representation of “wise” caffeine use: if I wanted to enhance my performance with caffeine, I’d take it immediately before the “critical situation”, for example an exam.
How do you want to die? Quickly, painlessly, peacefully lying in your own bed?
Most people say that. But then, people seem to cling to their lives, even if that could mean a less peaceful end. When asked whether they would want physicians to perform certain interventions to prolong their lives like CPR (cardiopulmonary resuscitation) or mechanical ventilation (‘breathing machine’), people say ‘yes’.
Interestingly, a study discussed in a Radiolab podcast from earlier this year reveals that contrary to lay people, physicians do not want these life-saving interventions they perform on their patients performed on themselves. Continue reading
Studies have shown that regular physical activity has benefits for mental health: exercise can help people to recover from depression and anxiety disorders. However, not all people like exercise, and a mental disorder like depression can additionally decrease motivation for physical activity. So the disorder itself might inhibit behaviour that helps to overcome it.
We would assume that pressurising people is no solution here: several studies have shown that restricting freedom of choice or control increases stress in both humans and animals. However, new research tentatively indicates that controllability might play a smaller role than expected when it comes to exercise, and that even forced exercise might protect against depression and anxiety symptoms:
I’ve been to Cologne recently, one of Germany’s main Carnival cities. In the window of a shop I passed, I saw some residues of the just ended Carnival season for sale – amongst other things, a Native American costume. Like many others of the sort, it consisted of a brown faux suede suit, a colourful feather hair decoration, and a little fake axe. And – not to my surprise – it showed far more skin that it concealed. Unfortunately, I didn’t take a picture. However, “Indian” Carnival and Halloween costumes like that can be found all over the internet, may it be in the (sadly unavoidable) “sexy” women’s version like the one I saw, or in the male “warrior / chief” version.
