Ecstasy Could Help Treat Anxiety

Ecstasy, or MDMA could help in the treatment of anxiety and post-traumatic stress disorder, say researchers.

Ecstasy, or MDMA could help in the treatment of anxiety and post-traumatic stress disorder (PTSD), say researchers.

MDMA has been a popular recreational drug since the 1980s, but there has been little research on which areas of the brain it affects. The new study is the first to use functional magnetic resonance imaging (fMRI) on resting subjects under its influence.

Post Traumatic Stress Disorder (PTSD) - Causes, Symptoms, Risk Factors, Complications, Dignosis, Treatment
Post Traumatic Stress Disorder (PTSD), is a mental condition triggered by a traumatic event. PTSD treatment includes pyschotherapy, behavior therapy and medications.

Twenty-five volunteers underwent brain scans on two occasions, one after taking the drug and one after taking a placebo, without knowing which they had been given.

The results show that MDMA decreases activity in the limbic system- a set of structures involved in emotional responses. These effects were stronger in subjects who reported stronger subjective experiences, suggesting that they are related.

Communication between the medial temporal lobe and medial prefrontal cortex, which is involved in emotional control, was reduced. This effect, and the drop in activity in the limbic system, are opposite to patterns seen in patients who suffer from anxiety.

Dr Robin Carhart-Harris from the Department of Medicine at Imperial, who performed the research, said: "We found that MDMA caused reduced blood flow in regions of the brain linked to emotion and memory. These effects may be related to the feelings of euphoria that people experience on the drug."

The study was published in the journal Biological Psychiatry.
