Background: Premenstrual tension has been known since long to affect the behavioural and physical well being of women. Behavioural differences in emotional and cognitive processing have been reported during premenstrual phase in women of reproductive age. Reaction time provides a means to assess psychomotor performance of an individual. Objectives: This study aims to compare sensory motor processing using reaction time para-digms during premenstrual & postmenstrual phases of menstrual cycle. Methods: Audiovisual reaction time of 100 healthy female medical students in the age group 17-21 years during pre and postmenstrual phases was taken with the help of a reaction time apparatus. Data was analysed using paired t test. Results: An increase in both visual reaction time and auditory reaction time was found dur-ing premenstrual phase (P value <0.05) compared to the postmenstrual phase. Conclusion: Hormonal fluctuations during premenstrual period modulate activity of centrally acting neurotransmitters involved in the process, thus prolonging the audiovisual reaction time.
