A new study from the University of California in Berkeley shows a lack of sleep, which is common in anxiety disorders, may play a key role in ramping up the brain regions that contribute to excessive worrying.
Neuroscientists have found that sleep deprivation amplifies anticipatory anxiety by firing up the regions of the brain associated with emotional processing. The resulting pattern mimics the abnormal neural activity seen in anxiety disorders. Furthermore, their research suggests that innate worriers – those who are naturally more anxious and therefore more likely to develop a full-blown anxiety disorder – are acutely vulnerable to the impact of insufficient sleep.
“These findings help us realize that those people who are anxious by nature are the same people who will suffer the greatest harm from sleep deprivation,” said Matthew Walker, a professor of psychology and neuroscience at UC Berkeley and senior author of the paper, published in the Journal of Neuroscience.
The results suggest that people suffering from such maladies as generalized anxiety disorder, panic attacks and post-traumatic stress disorder, may benefit substantially from sleep therapy.
