PRESENTATION OUTLINE

PARKINSON'S DISEASE

WHAT IS IT?

Parkinson's disease is a progressive nervous system disorder that affects how the person moves, including how they speak and write. Symptoms develop gradually, and may start off with ever-so-slight tremors in one hand. People with Parkinson's disease also experience stiffness and find they cannot carry out movements as rapidly as before - this is called bradykinesia. The muscles of a person with Parkinson's become weaker and the individual may assume an unusual posture.

Parkinson's results from the degeneration of nuclei in a number of dopamine-producing nerve cells in the brainstem. Dopamine is a neurotransmitter that stimulates motor neurons, which are nerve cells that control the muscles.

It’s estimated 500,000 to 1.5 million Americans live with Parkinson’s disease. Currently there is no cure, therapy, or drug to slow or halt the progression of Parkinson’s disease. While medication masks some symptoms for a limited period, generally four to eight years, dose-limiting side-effects do occur after time. Eventually the medications lose their effectiveness, leaving the person unable to move, speak or swallow.

In 1817, a British scientist named James Parkinson first described “the shaking palsy” in an essay. It was through this essay that he defined what we know as Parkinson’s disease today: “involuntary tremulous motion, with lessened muscular power, in parts not in action and even when supported; with a propensity to bend the trunk forwards, and to pass from a walking to a running pace: the senses and intellects being uninjured.”

The cause of Parkinson’s disease remains unknown, but scientists and researchers believe there to be both genetic and environmental factors. In October 2003, scientists at NIH discovered that too much of the alpha-synuclein gene may cause Parkinson’s disease. More recently, scientists at the University of California at Los Angeles discovered that some pesticides used on plants and crops that end up in well water are linked to an increased risk of Parkinson’s disease.
