A depressed nervous system may contribute to severe premenstrual syndrome (PMS), suggests a Japanese study in the journal BioPsychoSocial Medicine.
The researchers studied 62 women and found that those with PMS had decreased activity in the autonomic nervous system each month just before menstruation. This was most pronounced in women with the most severe PMS symptoms, BBC News reported.
The findings suggest that women with lower autonomic nervous system function may be more vulnerable to PMS symptoms, said researcher Dr Tamaki Matsumoto.
The study results are interesting, but more research is needed before it could lead to a real breakthrough in PMS treatment, said Professor Shaughn O'Brien, an obstetrics and gynecology expert at Keele University Medical School in the UK.
"If the newly published work did prove to be clinically useful it has the potential, at least, to provide a relatively non-invasive method to distinguish women with PMS from those who have different non-hormonal types of mood disorder," O'Brien said. – (HealthDay)
