My research training is in psychiatric epidemiology. Alcohol and drug dependence have been two of my topic areas of research.So I found a recent novel study of the epidemiology of illicit drug use in Europe intriguing.Typical methods of looking for the prevalence of drug use in populations are direct diagnostic interviews and studies of emergency room attendees or autopsy cases with medical complications of drug use.However, Christopher Ort from Switzerland along with a host of European col........

When you're trying to learn, do something with your new knowledge, such as summarising it or explaining it to someone else. This deepens your memories and helps integrate what you've learned with what you already knew. A new study has tested the benefits of another beneficial learning activity - drawing.Annett Schmeck and her team asked 48 German school-kids (average age 14) to read a 850-word passage about the biology of influenza, broken down into seven paragraphs. This was an unfamiliar topic........ Read more »

High scorers on the personality trait of agreeableness are eager to please, concerned for others, and compliant to other perspectives. On average, they live happier lives too. A new study suggests a possible reason: when they have the chance, friendly people tend to avoid engaging with negative things.The researchers, Konrad Bresin and Michael Robinson, began by asking participants to view a series of positive and negative images, spending as much time as they wanted on each one. Most people lin........ Read more »

Malocclusion, orthodontics and quality of life? One of the most important areas of orthodontic research that needs to be carried out is to clearly identify the effects of treatment.

I've mentioned a few times on this blog that a diagnosis of autism or autism spectrum disorder (ASD) is by no means protective against any other diagnosis being received, be it based on a somatic illness or condition, or something more behaviourally defined.Reading through the paper by Liz Forty and colleagues  (open-access) it appears that a similar scenario might also pertain to other behaviourally-defined conditions as per the example of bipolar disorder (BD) and their conclusion: "Bi........

A new analysis has found that while clinical trial data support omitting radiation treatments in elderly women with early stage breast cancer, nearly two-thirds of these women continue to receive it. The findings are published early online in CANCER, a peer-reviewed journal of the American Cancer Society.

The stomach strikes again, or so it seems.

What you are eating may be causing inflammation in the brain.... Read more »

In the days shortly after giving birth, most mothers experience a period of increased calmness and decreased stress responses, but around 20% of mothers experience anxiety. Some women may become depressed, and around one in a thousand can develop psychosis. The latest evidence indicates that these distressing responses to motherhood are still poorly understood, but that animal research could provide valuable clues to their causes.
