Severe, Acute Maternal Stress Linked to the Development of Schizophrenia

21.08.2008
Pregnant women who endure the psychological stress of being in a war zone are more likely to give birth to a child who develops schizophrenia. Research published today in the open access journal BMC Psychiatry supports a growing body of literature that attributes maternal exposure to severe stress during the early months of pregnancy to an increased susceptibility to schizophrenia in the offspring.

According to Dolores Malaspina from NYU School of Medicine and lead author of the study, “The stresses in question are those that would be experienced in a natural disaster such as an earthquake or hurricane, a terrorist attack, or a sudden bereavement”.

Data from 88,829 people, born in Jerusalem from 1964 to 1976, were collected from the Jerusalem Perinatal Study that linked birth records to Israel’s Psychiatric Registry. The NYU authors discovered that the offspring of women who were in their second month of pregnancy during the height of the Arab-Israeli war in June of 1967 (the “Six Day War”) displayed a significantly higher incidence of schizophrenia over the following 21-33 years. The study also showed that the pattern was gender-specific, affecting females more than males.

Following the 1967 war, females who had been in their second month of fetal life during the conflict were 4.3 times more likely to develop schizophrenia than females born at other times. Males in their second month of fetal life were 1.2 times more likely to develop schizophrenia. “It’s a very striking confirmation of something that has been suspected for quite some time”, said Malaspina.

“The placenta is very sensitive to stress hormones in the mother,” explains Malaspina, “these hormones were probably amplified during the time of the war.”

The authors point out that the study, which assessed ongoing medical records, only supports, rather than proves, the hypothesis that the greatest vulnerability to schizophrenia is in the second month of pregnancy. Limitations to the study include a small sample population as well as the absence of information on the exact length of gestation, which makes it possible that developmental stages were underestimated.

Malaspina also points out that pregnant women in general should not be alarmed about handling daily stressors during pregnancy. “A developing fetus requires some exposure to maternal stress hormones as it normalizes their stress functioning,” she says. “But women experiencing anxiety or excessive stress would do well to address it before a planned pregnancy and to have good social support systems.”

Im Focus: It’s All in the Mix: Jülich Researchers are Developing Fast-Charging Solid-State Batteries

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.

The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
