AI shows potential as a beneficial aid in mental health treatment, UIC study indicates

A recent pilot study by researchers from the University of Illinois Chicago (UIC) brings forth promising insights into the application of Artificial Intelligence (AI) in mental health treatment. The study demonstrates encouraging correlations between the use of an AI voice assistant named Lumen and improvements in symptoms of depression and anxiety in patients, along with noticeable changes in their brain activity.

The UIC study brings hope for the inclusion of virtual therapy in addressing the existing gaps in mental health care. The limited availability of mental health professionals and unequal access to mental health services, particularly among vulnerable communities, often impede proper treatment. The application of AI could potentially circumvent these obstacles.

Dr. Olusola A. Ajilore, UIC Professor of Psychiatry and a co-author of the study, noted the urgent necessity for innovative treatment methods, especially in the aftermath of COVID-19, which resulted in a surge of anxiety and depression cases. He remarked, “This technology could serve as a bridge. It isn’t meant to supersede traditional therapy, but it could be a vital intermediary measure before someone seeks treatment.”

Lumen, which functions as a skill within the Amazon Alexa application, is the brainchild of Dr. Ajilore, Dr. Jun Ma, the senior author of the study, and their colleagues from Washington University in St. Louis and Pennsylvania State University. The National Institute of Mental Health provided a $2 million grant to support the development of Lumen.

The researchers enlisted over 60 patients for this clinical study, which focused on the effect of the application on mild to moderate symptoms of depression and anxiety. The study also looked at activity in brain areas that have been associated with the advantages of problem-solving therapy. Two-thirds of the participants engaged with Lumen through a study-provided iPad for eight problem-solving therapy sessions. The remaining participants served as a control group that did not receive any intervention.

Upon concluding the intervention, the participants who interacted with the Lumen app exhibited reduced scores for depression, anxiety, and psychological distress in comparison to the control group. Moreover, these participants demonstrated enhanced problem-solving skills and increased activity in the dorsolateral prefrontal cortex, a brain region related to cognitive control. The results showed particular promise among women and underrepresented populations.

Dr. Ma highlighted the significance of problem-solving therapy delivered through the Lumen app. He stated, “It’s about reshaping the way people perceive problems and their approach to solving them without being overwhelmed by emotions.”

A comprehensive trial comparing the efficacy of Lumen to a control group on a waitlist and patients receiving human-guided problem-solving therapy is presently underway. However, Dr. Ma emphasises that the aim of the virtual coach is not to outperform human therapists but to address the critical shortages in the mental health system.

He concluded, “Digital mental health services should be viewed as a means to bridge the gap between the supply and demand of mental health care. We need to identify innovative, effective, and safe ways to deliver treatments to individuals who might otherwise lack access, thereby filling this gap.”
