Symptoms experienced during the premenstrual period lead to results such as mood/affective disorder in women, deterioration in daily life activities and social relations, an increase in negative health behaviors, as well as low academic performance in students, decreased participation in classes, getting low grades in exams, and not showing up for exams.Since its etiology is unclear, no specific treatment method can be found, and non-pharmacological therapies such as stress control, lifestyle changes, exercise and complementary therapies such as evening primrose oil, chasteberry and acupuncture are applied in its management.

Psychiatrist Carl Gustav Jung discovered the psychic healing transformations created by mandala painting, one of the art therapy methods, through his own experience and that of his patients.
