The GDNF gene therapy is currently used to treat Parkinson’s disease but could now be a major breakthrough in substantially reducing alcohol use disorder. “Drinking went down to almost zero,” Grant told OHSU News. “For months on end, these animals would choose to drink water and just avoid drinking alcohol altogether. They decreased their drinking to the point that it was so low we didn’t record a blood-alcohol level.”

Grant and her team said in the study that the resounding efficacy of GDNF gene therapy is promising for those who struggle with alcohol use disorder, and believe it could be effective in treating other substance abuse disorders. However, the therapy treatment would not be widely accessible and with other options on the market, it should be used as a last resort form of treatment.

Columbia researchers have identified brain injuries that may underlie hidden consciousness, a puzzling phenomenon in which brain-injured patients are unable to respond to simple commands, making them appear unconscious despite having some level of awareness.

“Our study suggests that patients with hidden consciousness can hear and comprehend verbal commands, but they cannot carry out those commands because of injuries in brain circuits that relay instructions from the brain to the muscles,” says study leader Jan Claassen, MD, associate professor of neurology at Columbia University Vagelos College of Physicians and Surgeons and chief of critical care and hospitalist neurology at NewYork-Presbyterian/Columbia University Irving Medical Center.

The findings could help physicians more quickly identify brain-injured patients who might have hidden consciousness and better predict which patients are likely to recover with rehabilitation.
