Is it true that the exact cause of premenstrual syndrome is currently unknown to researchers?

Yes. Current medical literature supports the claim that the precise underlying pathophysiology and exact root causes of premenstrual syndrome remain incompletely understood, though various hormonal, neurotransmitter, and lifestyle factors are heavily implicated.

Verdict: SUPPORTED · 3 sources for, 0 against · Last checked

The analysis

The claim is specific and empirical, passing Step 0. The retrieved literature (such as papers 0, 5, and 9) consistently points out that while triggering events (like luteal phase hormonal fluctuations) and contributing neurotransmitter systems are known, the exact precise pathophysiology and definitive primary causes remain complex, evolving, and not fully understood. Thus, the balance of evidence strongly supports the claim.
