Individuals with recurrent isolated sleep paralysis (RISP) show notable brain changes, including an increased cerebellar vermis height and a larger midbrain-pons junction. In a study of 20 participants (10 with RISP, average age 24.7; 10 controls, average age 26.3), MRI scans revealed these significant morphological differences, suggesting an over-compensatory mechanism in the brain's regulatory pathways. Despite these findings, no major variations in overall sleep structure were observed between the two groups, indicating that RISP may involve specific brain adaptations rather than broader sleep disturbances.
