Recent pre-clinical research from German scientists sheds light on the promising role of psilocybin in addressing this issue.
Researchers from the University of Heidelberg conducted a study using rat models that mirror alcohol addiction and found that psilocybin effectively curbed alcohol cravings, as revealed in the prestigious journal Science Advances.
The encouraging effects of psilocybin can be attributed to its capacity to restore the expression of a specific glutamate receptor known as mGluR2. This study demonstrated that decreased expression of this receptor is responsible for both alcohol cravings and the impairment of executive functions, such as self-control and decision-making.
The study commenced by exposing the rats to alcohol vapor, causing intoxication levels similar to those experienced by individuals with clinical alcohol addiction. Over a span of seven weeks, the rats developed enduring behavioral and molecular changes in their brains as they became dependent on alcohol.
To test the efficacy of psilocybin in preventing relapses, the researchers administered two different doses of the substance to the rats. Both doses proved to be effective compared to the control treatment, highlighting psilocybin's potential as a treatment for AUD.
Understanding the molecular mechanisms behind executive function deterioration in AUD remains a challenge, prompting further investigation. The research revealed that reduced mGluR2 expression in a specific cortical region triggers alcohol-seeking behavior and cognitive inflexibility in the animal model.
The research team further explored the potential of psilocybin to restore the receptor's expression, diminish the desire for alcohol, and restore cognitive flexibility. Not only did the treatment reduce alcohol cravings, but it also decreased alcohol-seeking behavior in the rat models, consequently lowering the risk of relapse.
Psilocybin is also being investigated for various conditions, including depression.
While the potential of psychedelics like psilocybin is compelling, there are still hurdles to overcome in the field of psychedelic research, including federal regulations, ethical considerations, intellectual property challenges, and the societal stigmas attached to these substances. Compass Pathways' trial, in particular, raised concerns about suicidal ideation in some patients and the durability of the treatment.
The German research team has outlined a strategy for further exploring the use of psilocybin in individuals with alcohol dependency.
Their proposed approach involves enrolling patients with the identified biomarker in a psilocybin trial and using MRI scans to monitor improvements in brain "functional connectivity" after a single dose. If positive results are observed, a more extensive controlled trial could be designed to assess whether psilocybin effectively reduces alcohol cravings and prevents relapses.
