Parkinson's was originally called a "shaking palsy". Parkinson's disease is a brain disorder that causes a gradual loss of muscle control. This disease mostly affects older people but can also occur in younger adults. It usually begins between the ages of 50 and 65, striking about 1% of the population in that age group; it is slightly more common in men than in women.
Symptoms
Symptoms Symptoms of Parkinson's disease differ from person to person. Parkinson’s disease affects the nerve cells in the brain that produce dopamine. Parkinson’s disease symptoms include muscle rigidity, tremors, and changes in speech and gait. After diagnosis, treatments can help relieve symptoms, but there is no cure.
Statistical analysis
The life expectancy of people with Parkinson is reduced. Cognitive decline and dementia, old age at onset, a more advanced disease state and presence of swallowing problems are all mortality risk factors. On the other hand, a disease pattern mainly characterized by tremor as opposed to rigidity predicts an improved survival. In 2013 PD resulted in about 103,000 deaths globally, up from 44,000 deaths in 1990. The death rate increased from an average of 1.5 to 1.8 per 100,000 during that time.
