The idea is certainly not new. Using VR immersion as a part of mental health treatment has been a subject of academic research and debate for a couple of decades. What usually makes news are opinion articles and university research projects.
I’ve seen commercially-oriented companies (like VirtuallyBetter) but none that gave me the impression of a true ‘VR platform for Psychiatrists’. Limbix seems to be the (?)first silicon valley outfit to tackle the workflow, documentation and content needs involved in integrating immersive VR therapy to mental health. Their website is terse, as usual for a startup, so most of this is my gut feel.
Using VR (or AR) to help patients overcome anxiety, phobias and other mental health conditions is in care delivery future. Reminds me of the optimism in late 90s when PACS technology was washing up on the shores of film-based radiology field. Limbix is to be filed away as a representative attempt at a viable digital health niche.
