Parkinson’s disease is a chronic, progressive movement disorder associated with the abnormal functioning of the central nervous system. The disease generally comes under a group of conditions known as motor system disorders. The disease is expressed due to the loss of dopamine-producing brain cells.
How Prevalent is Parkinson’s Disease?
The CDC, Centers for Disease Control, estimates that the age-adjusted death rate for the disease has increased drastically from 2000 to 2015. The death rate for males suffering from the disease was 8.8 per 1,000,000 population at the end of 2000. This increased to 13.5 by the end of 2014. Similarly, the death rate of females suffering from the disease was 3.9 at the end of 2000. This represents an increase of 4.8 percent. Men are more prone to the disease than females. The disease is more prevalent in caucasians than other races.
The human brain is the principal organ, controlling movement, memory, speech, vision, etc. This control can be acquired by the passage of different signals to the different organs of the body. These signals are generated in the brain, passed on to the different organs via brain cells, known as neurons. These signals are passed on from one neuron to other organs of the body with the help of neurotransmitters. Dopamine is one type of neurotransmitter which is absent in patients with Parkinson’s disease. This dopamine is degenerated due to the deposition of proteins or lewy bodies surrounding the neurons. These lewy bodies interrupt the transmission of signals due to loss of dopamine leading to the progressive degeneration of motor neurons.
Thus, motor coordination is affected to a great extent.
