What is Parkinson's disease?.
Parkinson's disease was first described in England in 1817 by .
Dr. James Parkinson. He found out that Parkinson's disease is a .
disorder of the brain characterized by shaking, and difficulty with .
walking, movement and coordination. The term Parkinsonism refers to .
any condition that involves a combination of type of change in .
movement seen in Parkinson's disease .The disease is caused by .
damage to part of the brain that is involved with movement. It affects .
approximately 2 of every 1,000 people, after the age of 50. Sometimes .
Parkinson's disease occurs in younger adults and is rarely seen in .
children. It affects both men and women, but it is most common .
neurologic disorders of the elderly. But cases have found that it .
occurs within families, especially when it affects young people.
Parkinson's disease sometimes is described as early, .
moderate, or advanced. Early is describes the stage when a person has .
a mild tremor or stiffness, but is able to continue work or other .
normal daily activities. This is when it affects one side of the brain.
Next is moderate. This is said to be the stage when a person begins to .
experience limited movement. A person with moderate will start to have .
mild tremor with slow movement. Both sides of the brain are affected, .
but posture remains normal. Then there is the advanced. This is when .
a person is significantly limited in his or her activities, despite .
treatment. There will be a change in posture and movement, speech .
problems and frequent change in movement. Both sides of the brain .
are affected and there is disabling instability while standing or walking, .
and they need help.
Who it is caused?.
Dopamine, which is one of the substances used by cell to .
transmit impulses, is normally produced in this area. Deterioration of .
this area of the brain reduces the amount of dopamine available to the .
