Why More Young People Are Suddenly Being Diagnosed With Parkinson’s Disease

Every year, April 11 is observed worldwide as World Parkinson’s Day, while the month of April is recognized as Parkinson’s Awareness Month. Parkinson’s disease has emerged as a major health concern among the elderly, as it gradually reduces a person’s ability to work, mobility, and mental efficiency. This article discusses the history, causes, symptoms, treatment, and statistics related to Parkinson’s disease while preserving the original essence of the subject.

History of Parkinson’s Disease

References to symptoms resembling Parkinson’s disease can be found in ancient Indian and Chinese medical texts. In modern medicine, however, the disease was formally identified in 1817 by London physician James Parkinson. In his famous paper “An Essay on the Shaking Palsy,” he described the symptoms of the disease in detail. Interestingly, he originally named the condition “Paralysis Agitans.”

Later, in 1867, renowned neurologist Jean-Martin Charcot conducted more advanced research on the disease and renamed it “Parkinson’s Disease” in honor of James Parkinson.

In 1893, scientists discovered that the disease was associated with pathology in a part of the brain known as the Substantia Nigra. In 1919, Russian neurologist Konstantin identified microscopic abnormalities in the brains of Parkinson’s patients and termed them “Lewy Bodies.”

A major breakthrough came in 1967, when scientist Arvid Carlsson established that dopamine deficiency was the primary cause of Parkinson’s disease and introduced the drug Levodopa. Later, in 1997, the discovery of genetic causes of the disease led to the approval of a surgical treatment known as Deep Brain Stimulation (DBS).

Causes of Parkinson’s Disease

The primary cause of Parkinson’s disease is the deficiency of dopamine, an essential chemical messenger responsible for movement, memory, concentration, motivation, and feelings of pleasure. A reduction in dopamine levels often leads to mental exhaustion, physical weakness, and loss of enthusiasm.

In Parkinson’s disease, the nerve cells in the brain that produce dopamine gradually degenerate and die. These cells are mainly located in the Substantia Nigra region. Over time, abnormal protein deposits known as Alpha-Synuclein accumulate within these damaged nerve cells. These deposits are referred to as Lewy Bodies.

Another important cause is genetic mutation in specific genes such as SNCA, LRRK2, and PARK7. However, genetic causes account for only around 15% of Parkinson’s cases.

Environmental factors also play a role. Prolonged exposure to pesticides, air pollution, industrial waste, and other toxic substances may increase the risk of developing the disease. Parkinson’s disease is generally more common in people above the age of 60, and men are more frequently affected than women.

Symptoms

The major symptoms of Parkinson’s disease include:

• Tremors in the hands, fingers, or limbs
• Slowness of movement (Bradykinesia)
• Muscle stiffness and rigidity
• Changes in speech patterns
• Difficulty in writing
• Problems with body balance and coordination

Global Statistics

According to reports published by the Parkinson Foundation, nearly 90,000 new Parkinson’s cases are diagnosed every year in the United States, and around 1.1 million people are currently living with the disease there. The organization estimates that this number may rise to 1.2 million by 2030.

Among neurodegenerative disorders, Alzheimer's Disease ranks first globally, while Parkinson’s disease holds the second position. At present, more than 10 million people worldwide are living with Parkinson’s disease.

Parkinson’s Disease in India

In India, Parkinson’s disease affects approximately 15 to 43 people per 100,000 population. Experts predict that this number will rise significantly by 2030.

One alarming trend is that nearly 40–45% of Parkinson’s patients in India fall within the age group of 22 to 49 years, indicating that younger individuals are increasingly becoming vulnerable to the disease. Doctors attribute this rise to industrialization, air pollution, and changes in lifestyle.

Additionally, genetic history, head injuries, and male gender are considered major risk factors, particularly in northern India.

Treatment

The most widely used medicine for Parkinson’s disease is Levodopa (L-dopa), often regarded as the “gold standard” treatment. Levodopa converts into dopamine inside the brain and helps compensate for dopamine deficiency.

However, an enzyme called Dopa Decarboxylase may break down Levodopa before it reaches the brain. To overcome this problem, Levodopa is administered together with Carbidopa, which blocks the enzyme and ensures that a larger amount of the medicine reaches the brain effectively.

Expert Opinion

Dr. N. Damodaran, Head of Neurology at Rela Hospital, has stated that public awareness regarding Parkinson’s disease has increased considerably over the past decade.

He pointed out that many patients initially ignore early symptoms such as trembling of the hands or legs, often assuming them to be due to vitamin deficiency or general weakness. As a result, by the time they seek medical help, the disease has often progressed to a more serious stage.

Although Deep Brain Stimulation (DBS) surgery is available, its accessibility remains limited. Support groups are now being formed for patients and caregivers to provide education, physiotherapy, psychotherapy, and emotional support, which is considered a positive development.

New Research and Future Hope

Recently, the London-based science magazine New Scientist published an article discussing a potential new treatment for Parkinson’s disease.

Scientists at Swinburne University of Technology conducted experiments on mice by introducing Alpha-Synuclein protein through the nasal pathway, which resulted in Parkinson-like symptoms.

The mice were then divided into two groups. One group received a potential drug called Compound-X, while the other group received no treatment. After several days, researchers observed that the mice treated with the drug were significantly healthier than those that did not receive it.

The drug has reportedly received approval from the Food and Drug Administration. Scientists claim that its primary function is to help remove waste materials from the brain. However, further testing is still required before the medicine can be fully introduced.

Researchers remain hopeful that this drug may become a major breakthrough for Parkinson’s patients in the future.
