A novel form of treatment has been identified for one of the most common mental health issues globally, anxiety.Roughly one in three people will suffer from the condition at some point in their lives, experiencing irrational fear brought on by stressors ranging from spiders to public speaking.Current treatment options are limited. Some medications provide relief, but can also cause side effects. Cognitive behavioural therapy can also be used, typically exposure-based therapies that allow patients to gradually face and overcome their fears. But for a substantial proportion of sufferers, these options are not effective.
