Parkinson's Disease: Definition and Prevalence
Shaking, slowness of movement, and stiffness of the body - these mysterious movement disorders are experienced by a small percentage of the world's population. These are the symptoms of Parkinson's disease, a neurodegenerative condition that is caused by the loss of a specific type of neurons in the brain. This weakens muscle control and leads to various physical and mental challenges.
Definition: Parkinson's disease is a neurodegenerative condition that was first described by British physician James Parkinson. It occurs due to a decrease in the production of the neurotransmitter dopamine in a specific part of the brain. Dopamine is essential for movement control, and its absence leads to symptoms such as shaking, slowness, and stiffness.
Prevalence: Parkinson's disease is a relatively rare condition, affecting about 1 in 100 people over the age of 65. The risk of developing the disease increases with age, and it is more common in men than in women.
Symptoms: The symptoms of Parkinson's disease typically develop gradually and worsen over time. The most common symptoms include:
- Shaking, especially in the hands, arms, and legs
- Slowness of movement
- Stiffness of the body
- Difficulty with balance and coordination
- Speech problems
- Changes in mood and behavior
