Does the luteal phase worsen anxiety and checking behaviors?
Checking behaviors and anxiety-related brain responses stay about the same between cycle phases, but they are more strongly linked during the luteal phase.
What they did
Women were tested twice: once during mid-follicular phase and once during mid-luteal phase. At each test, researchers measured brain activity while women did an error-detection task and asked them to report how much they checked things in daily life.
What they found
Checking behavior and brain responses to errors were similar between phases. However, in the luteal phase, stronger brain error signals were more closely linked to more checking. Changes in checking between phases matched changes in brain error response. Progesterone in the luteal phase appeared to link these together.
What it means for you
This suggests progesterone in the luteal phase may amplify the link between anxiety and checking by changing error monitoring in the brain. This could explain why some women notice more anxious behaviors before their period. The main limitation is we don't know if this applies to women with obsessive-compulsive disorder.
