Parkinson's disease (PD) is a chronic and progressive movement disorder, meaning that symptoms continue and worsen over time. Nearly one million people in the US are living with Parkinson's disease.
The cause is unknown, and although there is presently no cure, there are treatment options such as medication and surgery to manage its symptoms. The specific group of symptoms that an individual experiences varies from person to person. Primary motor signs of Parkinson’s disease include the following.
tremor of the hands, arms, legs, jaw and face
bradykinesia or slowness of movement
rigidity or stiffness of the limbs and trunk
postural instability or impaired balance and coordination

The genetic abnormality is caused by mutations, Familial cases of Parkinson disease can be caused by mutations in the LRRK2, PARK2, PARK7, PINK1, or SNCA gene, or by alterations in genes that have not been identified. Mutations in some of these genes may also play a role in cases that appear to be sporadic (not inherited).
Parkinson’s affects the muscles of the body, impairing the ability to move easily. Similarly, PD affects the muscles of the face, reducing automatic facial expression. This makes communication more challenging.Parkinson’s affects the muscles of the body, impairing the ability to move easily.

the disease is heritable through past genetics. Or through other family members you had the disease previously. Parkinson's is common in people over 50 years of age.
