Nightmares Fluctuate Across the Menstrual Cycle and May be More Pronounced in Women With Premenstrual Syndrome

Brain and Behavior February 28, 2025 Léa Dobler, Océane Richard, Emmanuelle Clerici et al. 2 citations

Women with premenstrual syndrome (PMS) may experience more frequent nightmares during the premenstrual phase of their menstrual cycle. In a case series of seven women who kept daily dream diaries and tracked PMS symptoms over one menstrual cycle, nightmare frequency increased premenstrually, though no formal statistical comparison was made between those with and without PMS. A therapy called imagery rehearsal therapy (IRT), conducted weekly for one month, significantly reduced nightmare severity overall, but this effect was not significant in the PMS subgroup. These findings suggest a link between PMS and nightmares that warrants further investigation in larger studies.

The nightmare severity index (NSI): A short new multidimensional tool for assessing nightmares.

Journal of Sleep Research May 1, 2024 Pierre A Geoffroy, Émilie Stern, Julia Maruani et al.

A new multidimensional scale, the Nightmare Severity Index (NSI), was tested in 102 patients, mostly women (64%) and outpatients (76%) with mood disorders (depression 31%, bipolar disorder 41%) and frequent PTSD comorbidity (44%). The NSI assesses nightmare frequency, emotional impact, diurnal impact, and nocturnal impact. The questionnaire showed good internal consistency (Cronbach's alpha >0.7) and was well suited for factor analysis. Higher NSI scores corresponded to individuals meeting DSM-5/ICSD-3 criteria for nightmare disorder. The NSI appears to be a promising tool for clinical assessment of nightmare severity.
