Hyperactivation of amygdala is a neural marker for post-traumatic stress disorder (PTSD) and improvement in control over amygdala activity has been associated with treatment success in PTSD. In this randomized, double-blind clinical trial we evaluated the efficacy of a real-time fMRI neurofeedback intervention designed to train control over amygdala activity following trauma recall. Twenty-five patients with PTSD completed three sessions of neurofeedback training in which they attempted to downregulate the feedback signal after exposure to personalized trauma scripts.

Article Synopsis
- PTSD is a common and debilitating condition, but its impact on reward functioning, particularly through the lens of anhedonia, remains under-researched.
- Most past research has mainly focused on fear-related aspects of PTSD, such as fear learning and extinction.
- The review calls for more studies to explore how trauma influences the reward system, as this knowledge gap could be hindering advances in PTSD treatment.
