[Postpartum dysphoric syndrome. Psychopathology, diagnosis and etiology]

About half of newly delivered mothers suffer a transient phase of emotional lability or sadness a few days after parturition around the 2nd and 5th day after delivery. The transitory psychopathology of the postpartum blues is similar to premenstrual tension, whose main symptom is irritability. The essence of the postpartum blues is not depression, but a sudden, fleeting and unexpected mood change with anxiousness, low spirits, tearfulness, confusion, poor concentration and forgetfulness. The aetiology of this disorder is unknown. It is well known that oestrogens and progesterone modify catecholamine concentration and the density of adrenergic, noradrenergic und dopaminergic receptors in the limbic structures of the central nervous system. But most of the neurochemical studies have not distinguished between postpartum blues and other forms of depression found in women and occurring postpartum. Those research groups who defined a group with a dysphoric peak in the early puerperium could not find a significant correlation between sex hormone levels, neurobiochemical data, and postpartum mood changes.
