A brain-health framework for PTSD: integrating digital biomarkers into multimodal assessment.

We propose a novel framework and measurement model that frames post-traumatic stress disorder (PTSD) in the context of brain health capital, utilising advances in smart devices (wearables, phones) and AI to better capture the multimodal physiological, behavioural, and cognitive features of PTSD. Patients would be provided with complex information in a meaningful way that could provide a unique opportunity to identify personal change mechanisms and support empowered, patient-led decision-making.
