We always like intriguing new stories about health and biology here. That’s why we’ve showcased this item from Peter Hess of the Mail, Do you have Social Anxiety? Scientists Find the Condition lives in your gut. Peter reports some results from University College, Cork. Essentially, scientists there have transferred gut material from people with Social Anxiety to mice. And found that they have thereby induced significant changes in the nervous systems of those creatures: specifically, making them more prone to anxiety and fear [1]
The work is undoubtedly interesting, and it’s good journalism to write it up Especially when it’s one of our old tropes, in this case the relationship between the the digestive system and the nervous system (LSS 9 3 23 and passim). Is it the answer to all our woes? It’s too early to say.
Essentially, journalists report two types of science story. Definitive ones, which answer all the questions and close the subject down. Or intriguing ones on early research which opens a subject up and sets the questions for future researchers. It’s our gut feeling that this work belongs in the second category. For one thing, the numbers are small (12 people and 72 mice, if our maths is anywhere near correct) Good start, but we’d like to see replication across much larger numbers. And what is Social Anxiety Disorder anyhow? Psychiatric conditions are notoriously hard to define exactly. Could there be other causes of anxiety, such as war service or growing up with violent parents? They need to be controlled for.
It’s good work in an intriguing area, and we hope these researchers are given more time and money to pursue it. But we still wait and see for definitive conclusions.
