Parkinson’s Disease

Parkinson’s disease is a chronic and progressive movement disorder, meaning that the disease never goes away. There are different symptoms and signs of this disease. The cause is unknown but there are certain treatments for this disease. Although there are treatments for Parkinson’s, there is no cure. Some know very little about Parkinson’s and some know nothing at all. The question here is, what is Parkinson’s disease?

Parkinson’s is associated with malfunction and even death of vital nerve cells in the brain. The area of the brain that is severely affected is called the substantia nigra. The neurons in this area of the brain produce dopamine, which is a chemical that sends messages to the part of the brain that controls movement. Slowly but surely the amount of dopamine manufactured in the brain will decrease. Decrease of dopamine can leave a person unable to control their own movements. Along with no control of their movement, there are many other symptoms.

Initial symptoms are tremor of the hands, arms, legs, jaw, and face, bradykinesia or slowness of movement, rigidity or stiffness, and postural instability or impaired balance. Those are considered primary motor symptoms. Secondary motor symptoms include: Freezing or hesitation in their gate, micrographia or shrinking in handwriting, mask-like expression, and unwanted accelerations or movements that are too quick instead of too slow. Some others that patients may experience are stooped posture, dystonia, speech problems, difficulty swallowing, cramping, and
