Primary Dysmenorrhea: Severe Menstrual Pain Is Associated with Lower Cognitive and Daily Functioning
A new European Journal of Obstetrics & Gynecology study of 138 women aged 17‑25 found that primary dysmenorrhea is linked to measurable declines in attention, processing speed, self‑esteem, and occupational performance. The researchers tracked participants across three menstrual phases and observed consistent cognitive and emotional deficits, especially during the luteal phase. Negative beliefs about menstruation amplified these effects, while pain‑free peers showed stable performance. The findings suggest that severe menstrual cramps extend beyond physical discomfort to impair daily functioning in school and work settings.
Neuroscientists Just Upended Our Understanding of Pavlovian Learning
Neuroscientists at UCSF discovered that the brain’s learning rate depends on the elapsed time between rewards rather than the number of cue‑reward pairings. Experiments with mice showed that longer intervals (up to 600 seconds) produced proportionally faster acquisition, resulting in...
