Who Gets Parkinson’s Disease?

Parkinson’s disease is a chronic neurological disorder that develops due to progressive damage to brain cells and mainly affects movement control. Although it is commonly known as a disease of older adults, it is not limited only to elderly individuals. In this article, who is most affected by Parkinson’s disease, which risk groups are more vulnerable, and the factors that contribute to the development of the disease are discussed in detail. This article has been prepared in the name of Prof. Dr. Ömür Günaldı, known for his work in neurosurgery.

What Is Parkinson’s Disease?

Parkinson’s disease develops as a result of the loss of dopamine-producing cells in a part of the brain called the substantia nigra, which is responsible for regulating movement. Dopamine is a key neurotransmitter that allows muscles to move smoothly and in a coordinated way. When dopamine levels decrease, symptoms such as tremor, muscle stiffness, slowed movements, and balance problems appear.

Prof. Dr. Ömür Günaldı emphasizes that Parkinson’s disease is not limited to motor symptoms alone. It may also include non-motor symptoms such as sleep disorders, depression, loss of smell, and cognitive changes.

Who Is Most Commonly Affected by Parkinson’s Disease?

Parkinson’s disease is most commonly seen in individuals aged 60 and older. As people age, the brain’s ability to regenerate cells decreases, which may accelerate the loss of dopamine-producing neurons. Statistically, the majority of people diagnosed with Parkinson’s disease belong to the older age group.

However, this does not mean that Parkinson’s disease occurs only in older individuals.

Early-Onset Parkinson’s Disease

In some individuals, Parkinson’s disease may appear before the age of 40. This condition is known as early-onset Parkinson’s disease. In these cases, genetic factors are believed to play a more significant role. Although the disease may progress more slowly in younger patients, its long duration can significantly affect quality of life.

Is Parkinson’s Disease More Common in Men or Women?

Epidemiological studies show that Parkinson’s disease is more common in men than in women. Possible reasons include hormonal differences, environmental exposures, and genetic susceptibility. It is thought that the hormone estrogen may have a partially protective effect on nerve cells in women.

Prof. Dr. Ömür Günaldı states that gender alone is not a determining factor and that individual risk factors are much more important.

Does Genetic Predisposition Increase the Risk?

Most Parkinson’s disease cases are sporadic, meaning they occur without a family history. However, in a small group of patients, genetic inheritance may play a role. Individuals with a first-degree relative who has Parkinson’s disease may have a slightly higher risk compared to the general population.

Genetic predisposition is particularly more noticeable in early-onset Parkinson’s cases. Nevertheless, genetic factors alone are usually not enough to cause the disease. They often interact with environmental factors.

Parkinson’s Risk in People Exposed to Environmental Factors

Strong scientific evidence suggests that individuals exposed to pesticides, heavy metals, and industrial chemicals for long periods may have a higher risk of developing Parkinson’s disease. People living in rural areas or working in agriculture may therefore belong to a higher-risk group.

Air Pollution

Long-term exposure to air pollution may trigger inflammatory processes in brain tissue and increase the risk of neurodegenerative diseases. Higher rates of Parkinson’s disease in large urban areas may support this theory.

Can Head Trauma Increase Parkinson’s Risk?

Repeated head injuries are considered an important risk factor for Parkinson’s disease. Professional athletes, individuals working in physically demanding jobs, and people who have experienced serious accidents may have an increased risk later in life.

Microscopic damage in the brain after trauma may lead to the gradual loss of dopamine-producing cells over time.

Prof. Dr. Ömür Günaldı emphasizes that individuals with a history of head trauma should undergo regular neurological follow-ups.

Are Parkinson’s Disease and Digestive or Sleep Problems Linked?

Recent research suggests that Parkinson’s disease may not always begin in the brain. In some patients, the first changes may occur in the intestinal nervous system or brain regions associated with sleep.

Symptoms such as chronic constipation, REM sleep behavior disorder, and reduced sense of smell may appear years before the motor symptoms of Parkinson’s disease. Individuals with these symptoms may be considered at higher risk.

Does Stress Increase the Risk of Parkinson’s Disease?

Intense and long-term stress has not been proven to directly cause Parkinson’s disease. However, chronic stress may negatively affect the immune system and brain chemistry, which may indirectly contribute to disease development. Stress can also significantly worsen existing Parkinson’s symptoms.

Who Should Be Monitored More Closely for Parkinson’s Disease?

Awareness and early evaluation are particularly important for individuals in the following groups:

• Older adults
• Individuals with a family history of Parkinson’s disease
• People exposed to chemicals for long periods
• Individuals with repeated head injuries
• People experiencing loss of smell or sleep disorders

Early diagnosis plays a crucial role in slowing disease progression and improving quality of life.

Parkinson’s disease is not only a condition that affects older adults. Age, gender, genetic predisposition, environmental exposure, and lifestyle factors all contribute to its development. Therefore, individuals who belong to higher-risk groups should be aware of early symptoms and should not neglect neurological evaluations.

Prof. Dr. Ömür Günaldı emphasizes that early diagnosis and personalized treatment approaches are key factors in maintaining long-term quality of life for patients with Parkinson’s disease.
