Overview of Parkinson’s Disease
Parkinson’s disease is a progressive neurodegenerative disorder that affects movement and can also cause cognitive and behavioral changes. It is the second most common neurodegenerative disorder after Alzheimer’s disease, affecting approximately 1% of people over the age of 60 and becoming more prevalent with age.
Named after the English physician James Parkinson, who first described the condition in 1817 as “shaking palsy,” Parkinson’s disease is characterized by the loss of dopamine-producing neurons in the substantia nigra region of the brain. Dopamine is a neurotransmitter that plays a crucial role in regulating movement and coordination.
The exact cause of Parkinson’s disease is still unknown, but researchers believe that it may be a combination of genetic, environmental, and lifestyle factors. While there is currently no cure for Parkinson’s disease, various treatment options aim to alleviate symptoms and improve quality of life for individuals living with the condition.
Common symptoms of Parkinson’s disease include tremors, stiffness, bradykinesia (slowness of movement), and postural instability. As the disease progresses, individuals may also experience non-motor symptoms such as cognitive impairment, depression, and sleep disturbances. Early diagnosis and proper management are key to slowing down the progression of the disease and maintaining functional independence.
Symptoms and Affected Body Parts
Parkinson’s disease is a neurodegenerative disorder that primarily affects the central nervous system. It is characterized by a progressive loss of dopamine-producing brain cells, leading to a range of motor and non-motor symptoms.
Motor Symptoms:

Causes of Parkinson’s Disease
Parkinson’s disease is a neurodegenerative disorder that primarily affects movement. While the exact cause of the disease is not yet fully understood, a combination of genetic and environmental factors is known to play a role in its development.
Genetic Factors
- Approximately 15% of Parkinson’s cases are believed to have a genetic component.
- Several genes have been identified that are associated with an increased risk of developing Parkinson’s disease, including SNCA, LRRK2, and PARK7.
- Individuals with a family history of Parkinson’s disease are at a higher risk of developing the condition themselves.
Environmental Factors
- Exposure to certain environmental toxins, such as pesticides and herbicides, has been linked to an increased risk of Parkinson’s disease.
- Studies have also suggested a potential link between head trauma and the development of Parkinson’s disease later in life.
Research into the causes of Parkinson’s disease is ongoing, and scientists continue to investigate the interplay between genetic and environmental factors in the development of the condition. Understanding the causes of Parkinson’s disease is crucial for developing more effective treatments and ultimately finding a cure.

Brain Structures Impacted by Parkinson’s Disease
Parkinson’s disease primarily affects certain key structures in the brain that are responsible for controlling movement and coordination. These brain areas include:
- Substantia Nigra: This region of the brain is essential for producing dopamine, a neurotransmitter that helps regulate movement. In individuals with Parkinson’s disease, the cells in the substantia nigra degenerate, leading to a significant decrease in dopamine levels.
- Basal Ganglia: The basal ganglia play a crucial role in coordinating muscle activity and movement. Disruption of the basal ganglia function due to Parkinson’s disease results in tremors, stiffness, and impaired movement control.
- Cerebral Cortex: The cerebral cortex is involved in higher-level executive functions, such as decision-making and planning. Parkinson’s disease can impact the cognitive abilities of individuals, affecting memory, attention, and problem-solving skills.
According to a study published in the Parkinson’s Foundation journal, approximately 60-80% of dopamine-producing cells in the substantia nigra are already lost by the time motor symptoms appear. This highlights the importance of early detection and intervention to slow down disease progression and improve quality of life.
Moreover, a recent survey conducted by the National Institutes of Health revealed that Parkinson’s disease affects around 10 million people globally, with a higher prevalence in individuals over the age of 60. Understanding the specific brain structures affected by Parkinson’s disease is crucial for developing targeted treatments and therapies to alleviate symptoms and enhance patient outcomes.
In conclusion, the impact of Parkinson’s disease on the brain structures involved in movement, coordination, and cognitive function underscores the complexity of this neurodegenerative condition. Ongoing research efforts aim to uncover new insights into the pathophysiology of Parkinson’s disease and pave the way for innovative treatment approaches.
