Survey study, 2024

# Can mood early in the cycle predict who will have PMS symptoms?

Possibly. Women with lower mood scores during the follicular phase showed reduced automatic nervous system activity as they moved toward their period, which may indicate PMS symptoms. The study is small and early-stage.

 Early or limited evidence

Women grouped by follicular phase mood (sample size not specified)

## What they did

Researchers asked women to complete a mood questionnaire during their follicular phase (early in their cycle) and sorted them into two groups: those with high positive mood and those with low mood. They then measured automatic nervous system activity using a pulse device at different points in the cycle.

## What they found

Women with low mood during the follicular phase showed reduced automatic nervous system activity from the follicular phase to the menstrual phase. This pattern suggests potential PMS symptoms. Women could be classified into PMS and non-PMS groups based on their early-cycle mood.

## What it means for you

Mood measured early in the cycle might help predict who will have PMS symptoms, which could make self-monitoring easier. However, the sample was small and the measurement device has limitations, so these findings are preliminary.
