Does impulsivity change across the menstrual cycle in women with PMS?
Yes. Women with PMS showed higher impulsivity on a risk-taking task, and this impulsivity changed across the menstrual cycle in a way not seen in other women.
What they did
Researchers gave women with PMS a computer-based risk-taking task to test impulsivity. They used a mathematical model to analyze how the women made decisions.
What they found
Women with PMS showed higher impulsivity on the task. This impulsivity changed across different parts of the menstrual cycle. This pattern of change across the cycle was only seen in women with PMS, not in the comparison group.
What it means for you
This suggests that impulsivity may be a lasting feature of PMS that gets stronger or weaker depending on where you are in your cycle. The main limits are that sample size is not clear, the mathematical model is very complex, and these findings would need to be tested in more women to confirm they're meaningful.
