GrayMatters Health Reaches Clinical Milestone of 10,000 Prism PTSD Patient Sessions

Highlights growing adoption of brain biomarker-powered treatment across the United States

NEW YORK, Feb. 9, 2026 /PRNewswire/ -- GrayMatters Health (GMH), the pioneers of digital brain biomarkers for mental healthcare, today announced an important milestone of 10,000 patient sessions with Prism™. The 10,000^th session was a patient treated at Breakthru Psychiatric Solutions, representing the growing number of patients benefitting from Prism self-neuromodulation for their post-traumatic stress.

"This is so exciting – a milestone that celebrates our patients and expanding access to effective treatments for post-traumatic stress," commented Karen Giles MD, psychiatrist and founder of Breakthru Psychiatric Solutions in Georgia. "Prism takes a different approach than the other interventions at our practice, focusing on the amygdala network to help patients learn to regulate automatic responses for better mental health."

During a Prism session, the patient explores finding a mental strategy – a personal memory, emotion or experience – that makes them feel calm to lower the level of a proprietary amygdala-based biomarker. This is automatically presented as animated characters sitting down in their seats and lowering their voices in the responsive simulation.

"Reaching 10,000 Prism sessions is a reflection of the trust of a growing number of psychiatrists to close the PTSD treatment gap," commented Kirk Thelander, Chief Commercial Officer at GrayMatters Health. "This milestone is continued validation of our digital brain biomarkers as a personalized and objective treatment paradigm with a growing number of patients using mental strategies in the clinic, at home and in daily life, anytime, anywhere."

In clinical studies and real-world practice, approximately 70% of PTSD patients experienced significant symptom improvement and 32% achieved remission with Prism. Side effects are mild and transient, allowing patients to resume daily activities immediately following completion of a session.
