First-time mothers 'face psychosis risk in first month'

A new study claims first-time mothers could be at a greater risk of developing psychosis in the month following the birth of the child.

Researchers in Sweden monitored the rates of psychosis in first-time mothers up to 90 days after childbirth between 1983 and 2000.

The study found that 892 women had been admitted to hospital due to the condition, which equated to a rate of 1.2 cases for every thousand births.

Of those first-time mothers who developed psychosis, the incidence rate was found to be highest during the first month following the birth of the child.

The study also found that women over the age of 35 are at "two times greater risk than women aged 19 or less".

Phillipa Hay, from the University of Western Sydney, said a number of "biological factors", alongside social and psychological aspects, "may contribute to post-partum psychosis in first-time mothers".

Eileen McLaughlin, professor from Newcastle University in Australia, recently received funding to investigate the health development of female eggs in the hope of improving fertility in older women, ABC News reported.
