Guided by the neurocognitive model of Nightmare Disorder, my research attempts to correlate PTSD and non-PTSD related Nightmare Disorder with several factors. This research project will use database data to look at which brain structures and brain activity patterns are correlated with different types of Nightmare Disorder. This project also collects surveys from adults with chronic nightmares in an attempt to correlate anxiety, mental activity, screen usage, and panic with chronic nightmare severity and with PTSD vs non-PTSD-related nightmares. Hopefully, this study will elucidate the different causes of PTSD and non-PTSD related Nightmare Disorder and lead to better treatment and understanding of the condition.
