The Menstrual Cycle Influences Emotion but Has Limited Effect on Cognitive Function

Area of Science:

• Neuroscience
• Psychology
• Reproductive Endocrinology

Background:

• The menstrual cycle is a key area of psychological research, influencing emotion, behavior, and cognition due to ovarian steroid fluctuations.
• Recent research focuses on sex differences in neuroscience and disparities in psychiatric/neurologic disorders.
• The menstrual cycle serves as a model for understanding hormone influences on the brain.

Purpose of the Study:

• To review emotion-related and cognitive findings from methodologically sound menstrual cycle studies.
• To examine sex hormone-induced emotional disturbances in premenstrual dysphoric disorder (PMDD).
• To discuss emotion processing and cognitive findings in healthy women across the menstrual cycle.

Main Methods:

• Review of existing literature on menstrual cycle studies.
• Focus on studies examining emotional and cognitive outcomes.
• Analysis of findings related to specific phases and hormones (estradiol, progesterone).

Main Results:

• Menstrual cycle differences in sexually dimorphic cognitive tasks are minimal and hard to replicate.
• Emotion-related changes are more consistently observed.
• These emotional changes are more strongly associated with progesterone and the luteal phase than with estradiol.

Conclusions:

• Cognitive variations across the menstrual cycle are subtle and lack consistent replication.
• Emotion-related changes are more reliably detected and linked to progesterone during the luteal phase.
• Understanding these hormonal influences is crucial for addressing sex disparities in neurological and psychiatric conditions.
