In a world where anxiety and depression can sometimes feel like silent epidemics, AI therapy is offering a ray of hope.
Could your friendly neighborhood voice assistant Alexa be the mental health therapist of the future?
A new pilot study offers some tantalizing evidence to suggest so.
The study, a test run of Lumen, a voice-activated AI coach, found that adults with mild-to-moderate depression or anxiety could benefit significantly from this virtual therapist.

The Dawn of AI Therapy
In a new study led by the University of Illinois Chicago researchers, a groundbreaking pilot put the AI to the test as a voice-activated behavioral therapist, and has produced promising results.
The findings of the study, the first to test such a tech-savvy approach, were published on May 12 in the Nature journal Translational Psychiatry.
More Than Just a Voice: The AI with a Healing Touch
Not just a lifeless voice from a box, Lumen is a multi-talented AI assistant, an Amazon Alexa application skill that delivers psychotherapy with a silicon lilt.
Depression and anxiety, brace yourselves, for here comes Lumen, lifting moods and reducing stress with an efficiency that surprised even its creators.
The research team, led by UIC psychiatry professor Olusola A. Ajilore and medicine professor Jun Ma, with input from experts at Washington University in St. Louis and Pennsylvania State University, found the AI’s therapy had tangible effects on patients’ brain activity.
The results underscored Lumen’s potential as a powerful ally in tackling mental health care disparities and long waitlists, particularly for those from vulnerable communities.
AI Therapy Assistant Shows Potential as Mental Health Game Changer
In the study, participants were randomized into two groups: those who engaged with Lumen for therapy (42 adults) and a control group who received no intervention (21 adults).
The research focused on changes in neural activity related to emotional reactivity and cognitive control and symptom scores from the Hospital Anxiety and Depression Scale (HADS) over 16 weeks.
The participants, predominantly women (68%), hailed from diverse ethnic backgrounds, thus providing a representative cross-section of the urban population.
A typical Lumen session lasted about 12 minutes.
The group engaging with Lumen showed a decrease in the activation of the right dorsolateral prefrontal cortex (dlPFC), a brain region associated with cognitive control, while the opposite was true for the control group.
This difference had a significant effect size (Cohen’s d = 0.3), indicating a meaningful impact.
These results also correlated with improvements in problem-solving abilities, and less avoidance behavior in the group interacting with Lumen.
But that’s not all. The Lumen group also reported lower depression, anxiety, and overall psychological distress scores on the HADS, showcasing medium effect sizes (Cohen’s d = 0.49, 0.51, and 0.55 respectively), in contrast to the control group.
A Beacon in the Darkness
These promising findings suggest that Lumen, and perhaps AI therapy in general, could be a game changer in mental health treatment.
Lumen is now set to dazzle in a larger trial, to be compared with a control group and patients receiving human-coached problem-solving therapy.
The researchers are quick to clarify that Lumen does not need to outdo human therapists, but rather fill a desperate need in the mental health system.
In a world where mental health care often seems like a luxury, Lumen’s promise is like a lighthouse on a dark sea, guiding the way to a more accessible and less stressful future.
