Some individuals with chronic combat-related posttraumatic stress disorder do not benefit from standard psychotherapies and often drop out of treatment. Innovative treatment techniques, such as virtual-reality, may be useful to help address treatment goals by promoting presence and overcoming cognitive avoidance to improve ability to reconsolidate the traumatic memory. This pilot study examined the...
Many conventional approaches and treatments being insufficient to restrain the repercussion caused due to disorder and disability have initiated exploration on Virtual Reality for therapy. Experts having done research on efficacy of VR to overcome mental disorders specifically Post traumatic stress disorder (PTSD) and phobias demonstrate the scope of technology to overcome physical illness. Use of...
Heart rate variability (HRV) is commonly used to analyze stress, anxiety, and depression in persons suffering from post-traumatic stress disorder (PTSD). Heart rate can be visualized using micro-movements in the skin using the Euler video magnification (EVM) method. HRV may be used to help persons with startle reactions associated with PTSD This paper examines how heart rate can be captured from video...
To survive in any environment, an organism needs to learn about places and things that may threaten its survival and to adapt its behavior accordingly. The existence of parallel neural systems that mediate acquisition and retrieval of aversive learning have been discovered through behavioral paradigms such as Pavlovian aversive conditioning. These neural systems encompass the amygdala, hippocampus,...
This chapter discusses mental health issues among the older population and provides counseling strategies that can be used in various situations. A general discussion regarding mental health of older people is provided, followed by foci on anxiety and stress, depression, suicide, sleep issues, PTSD, substance abuse and addictions, and psychiatric issues. Older people may experience anxiety or stress...
In this paper we profile the stress responses of patients diagnosed with post-traumatic stress disorder (PTSD) to individual events in the game-based PTSD stress inoculation and exposure virtual environment StartleMart. Thirteen veterans suffering from PTSD play the game while we record their skin conductance. Game logs are used to identify individual events, and continuous decomposition analysis...
The aim of this work is to construct a predictive algorithm based on linguistic computation to predict Post Traumatic Stress Disorder (PTSD) and comorbid conditions. Most contemporary work in psychometrics, concerns itself with the construction and validation of instruments in an attempt to measure personality, attitudes, sentiment and beliefs. Measurement of these phenomena is difficult and largely...
Post-traumatic stress disorder (PTSD) currently is diagnosed via subjective reports of experiences related to the traumatic event. More objective measures are needed to assist clinicians in diagnosis. Physiological activity was recorded from 58 participants. Participants in the No Trauma/No PTSD group had no trauma exposure and no PTSD diagnosis. Trauma Exposed/No PTSD participants had experienced...
This paper describes two systems that explore Virtual Reality technology and Fuzzy Logic to support and to control the assessment of people with Post-Traumatic Stress Disorder during the Virtual Reality Exposure Therapy.
Post-Traumatic Stress Disorder (PTSD) is an anxiety disorder triggered by exposure to traumatic stressors. At a molecular level, traumatic stress triggers the release of neurotransmitter dopamine (DA), and the corresponding receptors take the role of sensors that signals the fear conditioning (FD) circuit. The proteins in the FD neuronal circuit in turn activate the transcription factor CREB in amygdala...
Post Traumatic Stress Disorder (PTSD) is reported to be caused by exposure to an extreme traumatic stressor involving direct personal experience of (or witnessing/learning about) an event that involves actual or threatened death or serious injury, or other threat to one's physical integrity including (but not limited to) military combat, violent personal assault, being kidnapped or taken hostage and...
Posttraumatic Stress Disorder (PTSD) is reported to be caused by traumatic events that are outside the range of usual human experience including (but not limited to) military combat, violent personal assault, being kidnapped or taken hostage and terrorist attacks. Initial data suggests that at least 1 out of 5 Iraq War veterans are exhibiting symptoms of depression, anxiety and PTSD. Virtual Reality...
