February 3, 2010 — Participating in a sustained exercise program may decrease cognitive decline in patients older than 55 years, according to results from 2 new studies published in the January 25 issue of the Archives of Internal Medicine.
In a cohort study from Germany, investigators found that moderate or high physical activity was associated with a lower risk of developing cognitive impairment in patients older than 55 years.


Pregnant women haven't lost it after all
February 11, 2010 — It appears that the image of the dotty pregnant woman or the scatterbrained new mom is just an urban myth. New research shows that there is no evidence of cognitive decline during pregnancy or after giving birth.
"Pregnant women and new mothers might be distractible, but when the power of their intelligence is turned to a task, there’s absolutely no evidence that they’re impaired relative to nonpregnant women," lead Helen Christensen, PhD, Australian National University, Canberra, told Medscape Psychiatry.
Obstetricians, family doctors, and midwives may want to take note of these findings that suggest that "placenta brain" is not inevitable, she said.
The study is published in the February issue of the British Journal of Psychiatry.
