![]() In the future, VR systems may become an innovative clinical tool for patients with specific psychiatric symptoms. However, it is worth mentioning that VR systems relatively easily deliver virtual environments with well-controlled sensory stimuli. Although there is room for improvement, its widespread adoption in psychiatry is yet to occur due to technical drawbacks such as motion sickness and dry eyes, as well as user issues such as preoccupation and addiction. In terms of the different types of VR systems, we discuss the feasibility of the technology within different stages of dementia as well as the methodological limitations. Recent advances in VR technology also demonstrate potential abilities to address cognitive and functional impairments in dementia. Through cognitive training and social skill training, rehabilitation through VR therapies helps patients to improve their quality of life. We review empirical evidence from VR-based treatments on psychiatric illnesses such as dementia, mild cognitive impairment (MCI), schizophrenia and autism. Moreover, VR environments have shown the possibility of changing depression, cognition, even social functions. On top of that, exposure therapies with simulated images are beneficial for patients with psychiatric disorders such as phobia and posttraumatic stress disorder (PTSD). ![]() ![]() VR exposure therapies are particularly effective for anxiety, provoking realistic reactions to feared stimuli. In order to gain a better understanding of the management of pain and stress, we first investigate VR applications for patients to alleviate pain and stress during immersive activities in a virtual environment. We collected 36 studies that used VR to provide clinical trials or therapies for patients with psychiatric disorders. In this paper, we conduct a literature survey on various virtual reality (VR) treatments in psychiatry. ![]() 3Department of Electronic Engineering, Hallym University, Kangwon, South Korea.2Department of Health Sciences & Technology, Department of Medical Device Management & Research, and Department of Clinical Research Design & Evaluation, Samsung Advanced Institute for Health Sciences & Technology (SAIHST), Sungkyunkwan University, Seoul, South Korea.1Department of Psychiatry, Depression Center, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, South Korea.Mi Jin Park 1 Dong Jun Kim 2 Unjoo Lee 3 Eun Jin Na 1 Hong Jin Jeon 1,2* ![]()
