In the US, 1.3 million women reach menopause annually and an estimated 20% have depression during menopause. Depression is approximately twice more common in the woman than for men. Depressive symptoms are also more recurrent and longer in women.
Many of these women have symptoms of sleep disturbances, anxiety and stress which make them unable to have a smooth menopausal transition. Sleep alone has been shown to be major instigator for depression. The mind works overtime and does not rest. It then leads to unhealthy thoughts, tiredness and mood swings.
Women who have bad premenstrual syndrome and post-natal depression are at a higher risk for menopausal depression. As the worlds aging population is increasing, the risk of dementia will increase by 2050
