Worry… Worry… Worry… Worry… , by Linda Geddes.

One in six of us will suffer from an anxiety disorder at some time of our lives. Anxiety disorders are the most prevalent mental health problem in the Western World. It is worse for young people, and the focus of our anxieties tends to change over the course of a lifetime.

This article asks if it is getting worse, what are the causes of anxiety, whether there is such a thing as an anxious personality, and what are the best strategies to combat anxiety (physical exercise is quite a good one).

“The amygdala is linked to parts of the prefrontal and anterior cingulate cortex that process social information and help us make decisions. During bouts of everyday anxiety, this brain circuit switches off then on again – but Oliver Robinson at University College London and his colleagues have shown that in people with anxiety disorders it seems to get stuck in the on position.”

The Aftermath, by Jessica Hamzelou

Why are women more than twice as vulnerable to PTSD than men? New evidence suggests that oestrogen may play a role in the disorder. Vasiliki Michopulos at Emory University in Atlanta, Georgia, USA, is researching genetic and biochemical factors which influence anxiety.

“The horrible event may be over, but you’re held hostage by what happened to you.”

“As we discover how PTSD differs between people, we realise treatments should differ too.”
