Is this trial a fit for you?

Likely a good fit

Ideal candidates are English-speaking adolescents and young adults aged 12–21 with DSM-5 PTSD at least one year after the index trauma, normal or corrected vision/hearing, and the ability to provide consent or assent with guardian consent as required.

Probably not a fit

Patients with psychotic disorders, those who recently completed full courses of trauma-focused therapy (per investigator judgment), or those unable to attend in-person sessions or comply with procedures are less likely to benefit from this protocol.

What this trial studies

This is a prospective, single-arm, open-label trial that will enroll 35–45 adolescents and young adults with DSM-5 PTSD to receive Prism neurofeedback as an adjunct to standard care. Participants will complete 15 (±3) EEG-guided neurofeedback sessions delivered twice weekly over about eight weeks, with a mid-training visit after seven sessions, an end-of-training visit, and a one-month follow-up. The Prism software runs on a laptop using EEG input and the primary objective is to confirm the safety profile in this adolescent population, specifically the absence of device-related serious adverse events. All participants will receive the same active intervention without a control group, and outcomes will focus on safety and symptom changes over the training and follow-up period.

Why it matters

Potential benefit: If successful, Prism could provide a noninvasive adjunct therapy that helps reduce PTSD symptoms in adolescents while showing a favorable safety profile.

How similar studies have gone: Prism has prior FDA clearance for adult PTSD and adult studies have supported its safety and symptom effects, but its use in adolescents has not been confirmed.
