Virtual-Reality Therapy May Ease Substance Abuse Cravings

A new study suggests virtual-reality therapy may help to reduce people’s craving for tobacco and alcohol.

Although the findings come from a small sample of just 10 patients, researchers say they are optimistic about the potential for virtual reality as a therapy for alcohol use disorders.

The study appears in the Journal of Studies on Alcohol and Drugs.

Virtual reality therapy is a method of psychotherapy that uses virtual reality technology to give the patient a simulated experience that can be used to diagnose and treat psychological conditions that cause patients difficulty.

“The technology is already popular in the fields of psychology and psychiatry,” said senior researcher Doug Hyun Han, M.D., Ph.D., of Chung-Ang University Hospital in Seoul, Korea.

Virtual-reality therapy has been used to treat phobias and post-traumatic stress disorder, Han said.

The idea is to expose people to situations that trigger fear and anxiety, in a safe and controlled space. Then, hopefully, they learn to better manage those situations in real life.

Less is known about whether virtual reality can help with substance use disorders. But there has been some evidence that it can reduce people’s craving for tobacco and alcohol, according to Han.

For the new study, his team recruited 12 patients being treated for alcohol dependence. All went through a week-long detox program, then had 10 sessions of virtual-reality therapy, done twice a week for five weeks.

The session’s involved three different virtual scenes: one in a relaxing environment; another in a “high-risk” situation in which the patients were in a restaurant where other people were drinking; and a third, “aversive,” situation.

In that aversion scene, patients were surrounded by the sights, sounds, and smells of people getting sick from too much alcohol.

Before they began the program, all of the patients underwent positron emission tomography (PET) and computerized tomography (CT) brain scans, which allowed the researchers to study the patients’ brain metabolism.

Investigators discovered that when compared with a group of healthy people, the alcohol-dependent patients had a faster metabolism in the brain’s limbic circuit, which indicates a heightened sensitivity to stimuli, like alcohol.

After the virtual-reality therapy, however, the picture changed. Patients’ revved-up brain metabolism had slowed — which, Han said, suggests a dampened craving for alcohol.

According to Han, the therapy is a promising approach to treating alcohol dependence. That is partly because it puts patients in situations similar to real life and requires their active participation, he said.

The sessions are also “tailor-made” for each individual, he added. However, larger, long-term studies are still needed to show whether virtual reality ultimately helps patients remain abstinent and avoid relapses.
