Waking-hour cerebral activations in nightmare disorder: A resting-state functional magnetic resonance imaging study.
Psychiatry and Clinical Neurosciences December 1, 2016 Chanchan Shen, Jiawei Wang, Guorong Ma et al.
People with nightmare disorder show altered resting-state brain activity compared to healthy volunteers. Fifteen nightmare disorder patients and 15 healthy controls completed questionnaires and resting-state fMRI scans. Patients scored higher on measures of physical effect and horrible stimulation from nightmares. They had higher regional homogeneity (a measure of local brain connectivity) in the left anterior cingulate cortex and right inferior parietal lobule, and lower regional homogeneity in the left superior and inferior frontal gyri and bilateral middle occipital gyri.
