Anhedonia is a psychological condition defined as the reduced capacity to experience pleasure with an increase in emotional numbness. Anhedonia, while not popular by name, is a commonly met symptom associated with post-traumatic stress disorder (PTSD), depression, and anxiety. This condition is increasingly understood as a deviation in the brain’s reward processing system, particularly in the anticipatory and consummatory phases. Research suggests that emotional numbing and chronic stress occurs when dopamine pathways and motivational drive are disrupted. In this paper, a deep dive is taken into how Virtual Reality immersive programs, used in exposure therapy for treating anxiety disorders, can be adapted and programmed to specific scenarios that may help induce anhedonic states. The paper uses the Unpredictable Chronic Mild Stress (UCMS) model in animals to propose that VR scenarios simulating sensory deprivation and emotional desensitization stressors may replicate core features of anhedonia. Virtual platforms can be used to mimic disruptions in the hypothalamicpituitary-adrenal (HPA) axis and reward circuitry. Why is inducing anhedonia worth exploring? Inducing anhedonia in a controlled VR environment can help study whether this temporary psychological state can act as a bridge that can be used to mitigate negative reactions in humans, such as claustrophobia. When a subject experiences a temporal emotional numbing, it gives researchers the ability to reduce the emotionally heightened reactions commonly triggered by confined spaces. Ultimately, this research offers a novel direction in the use of VR: not only as a therapeutic tool but also as a controlled experimental medium to investigate emotional numbing and reward dysfunction.
