What is Parkinson’s disease?

Parkinson’s disease is a brain disorder. It occurs when certain nerve cells (neurons) in a part of the brain, called the substantia nigra, die or become impaired. Normally, these cells produce a vital chemical known as dopamine. Dopamine allows smooth, coordinated function of the body’s muscles and movement. It is not until approximately 80% of the dopamine-producing cells are damaged that the motor symptoms of Parkinson’s disease appear.

What are the signs and symptoms of Parkinson’s?

The loss of dopamine production in the brain causes the primary symptoms of Parkinson’s disease. The key signs of Parkinson’s disease are tremor (shaking), slowness of movement, rigidity (stiffness), and difficulty with balance. Other signs of Parkinson’s disease may include small, cramped handwriting, stiff facial expression, shuffling walk, muffled speech, and depression.

Who gets Parkinson’s?

Parkinson’s disease affects all genders, although more men than women are diagnosed. It shows no social, ethnic, economic or geographic boundaries. In the United States, it is estimated that 60,000 new cases are diagnosed each year, joining the 1 million Americans who currently have Parkinson’s disease. While the condition usually develops after the age of 65, 15% of those diagnosed are under 50.

How is Parkinson’s diagnosed?

The process of making a Parkinson’s disease diagnosis can be difficult. There is no single test that can confirm Parkinson’s disease. A physician arrives at the diagnosis only after a thorough examination. Blood tests and brain scans are known as magnetic resonance imaging (MRI) may be performed to rule out other conditions that have similar symptoms. People suspected of having Parkinson’s disease should consider seeking the care of a neurologist who specializes in Parkinson’s disease.

What is the treatment for Parkinson’s disease?

There are a number of effective medicines to help ease the symptoms of Parkinson’s disease. Most symptoms are caused by a lack of dopamine. The medicines most commonly used will attempt to either replace or mimic dopamine, which improves the tremor, rigidity and slowness associated with Parkinson’s disease. Several new medicines are being studied that may slow the progression. Currently, there is no cure that will prevent or reverse the symptoms of Parkinson’s disease. As the disease progresses, treatment plans may need frequent review and adjustment to maintain functioning and quality of life.
