Disease Research - Compare Genetic Cases with Environmental - Symptoms
and Treatments With Drugs
April 28th 2006
Researchers at the Mayo Clinic compared patients with Parkinson’s
disease which stems from genetic causes with patients who have no known
cause. These cases that have no known genetic cause make up 98% of all
Parkinson’s cases. They label these cases “sporadic”. Parkinson’s
disease affects approximately 1 million Americans causing tremors,
stiffness, slowness of movement and instability.
They found that the disease affects men twice as often as women. The
researchers speculate that this may be because women have a “protective
effect” or mechanism. For example, the hormone estrogen may act to
It has been thought that Parkinson’s may be caused by environmental
exposure to pesticides or chemicals, but researchers have also found six
genetic mutations responsible for causing Parkinson's disease in about 2
percent of all cases.
