Hormones May Help Shield Women from Parkinson's
But protection limited to natural hormones, not HRT, researchers note
Posted February 25, 2009

WEDNESDAY, Feb. 25 (HealthDay News) -- A women's own reproductive hormones 
may help protect her from developing Parkinson's disease, a new study finds.
Women with a longer fertile lifespan (the time from first menstruation to 
menopause) have a lower risk of the neurological disease, according to the 
findings released Wednesday and scheduled to be presented at the American 
Academy of Neurology's annual meeting in late April in Seattle.
Hormone replacement therapy did not seem to add any level of protection, the 
researchers noted.
"These findings suggest that longer duration of exposure to the body's own 
[endogenous] hormones may help protect the brain cells that are affected by 
Parkinson's disease," study author Dr. Rachel Saunders-Pullman, of Albert 
Einstein College of Medicine in New York City, said in a news release from 
the American Academy of Neurology.
Researchers have long believed a women's hormones may affect her chances of 
developing the disease. Parkinson's is much more common in men than women.
The study, which looked at nearly 82,000 postmenopausal women, also found 
that women with four or more pregnancies had a 20 percent greater risk 
developing Parkinson's than women with fewer pregnancies, a finding that 
Saunders-Pullman said needed more study.
Women who had hysterectomies (known as "menopause from surgery") had nearly 
double the odds of developing Parkinson's if they had used hormone therapy 
before surgery, compared to if they had never taken hormone therapy. No 
change in risk was apparent for those who used hormone therapy during their 
natural menopause.
