Parkinson disease (PD) is a condition where there is a gradual deterioration of the central nervous system. The condition is characterized by several neurological malfunctions with respect to motor skills, cognitive impairment, balance problems, psycho-emotional disruptions, cognitive disorder and other socio-behavioral disorders. PD is known to be a progressive disorder, and the conditions deteriorate over time. The average age in which PD is often diagnosed is 57 years.The symptoms of PD typically arise from degeneration of dopaminergic neurons. These are those neurons of the brain which produce dopamine.

Dopamine is a chemical responsible for transmitting electric impulses from neurons. A deficit of Dopamine results in disrupted transmission of nervous impulses – causing symptoms like tremors of limbs, jaws and facial muscles, slower movements and stiffness of muscles, difficulties in movement and maintaining balance etc.

Some of the other symptoms may include anxiety, depression, anxiety and dementia. Eventually, one may face difficulties in swallowing and chewing, abnormal appetite, excessive salivation, and bowel and urinary bladder disorders.
