The Experimental Therapeutics Branch is conducting a study examining the
effects of Estradiol on Parkinson's disease. I cut the following
information out of our web site:

Postmenopausal (or post-hysterectomy) female patients with Parkinson's
disease are invited to test the
short term motor effects of Estradiol, a major estrogen hormone secreted by
the body. The study will
evaluate the ability of this hormone, administered with skin patches, to
modify the symptoms of
Parkinson's disease and its complications. Healthy candidates must provide
documentation of a full and
satisfactory gynecologic examination obtained in the last 9 months, as well
as the results of a Pap smear
and mammogram. Candidates will be requested to stop temporarily their
regular hormonal replacement
therapy and perhaps some of their antiparkinsonian medications before study
entry. Hormonal status and
safety concerns during the study will be addressed through blood tests. The
study requires a few visits to
the NIH Outpatient Department Clinic and two short inpatient admissions to
the NIH Clinical Center. The
study is conducted over six weeks and though placebo-controlled, all
patients will receive the active
hormone drug treatment.

Drs. John Fang and Pierre Blanchet are supervising the study.

We are also conducting studies which examine the effects of novel
medications on motor fluctuations (on-off, wearing off, etc.) Our Web Site
