Parkinson’s disease is a neurodegenerative disorder that affects motor functions such as movement, balance, and coordination. It is caused by the loss of dopamine-producing cells in the brain.

Dopamine is a chemical messenger that helps regulate movement in the body.

1. Tremors

The most common symptom of Parkinson’s disease is tremors. Tremors are involuntary movements that usually start in one hand or arm and can progress to other body parts.

Tremors can occur when the person is at rest or when they are trying to perform a task. They usually stop when the person is sleeping or fully relaxed. Tremors are typically more pronounced when the person is feeling stressed or anxious.

2. Stiffness

Stiffness or rigidity is another symptom of Parkinson’s disease. This is caused by a decrease in the flexibility of the muscles. The person may have difficulty moving the limbs or may feel as if the limbs are heavy and difficult to move.

This can also affect the facial muscles, causing the person to have a blank or expressionless face.

3. Slowness of Movement

Slowness of movement or bradykinesia is another hallmark symptom of Parkinson’s disease. The person may have difficulty initiating movement or may move very slowly.

Simple tasks like buttoning a shirt, tying shoelaces or brushing teeth can become challenging for someone suffering from Parkinson’s disease. This can also affect the person’s ability to walk, and they may have a shuffling gait.

4. Poor Balance

Balance problems are common in people with Parkinson’s disease. The person may find it difficult to maintain their balance or may fall frequently. This can be accompanied by dizziness and lightheadedness, which can further impair balance.

5. Changes in Speech

Parkinson’s disease can also affect the person’s speech. They may speak softly, mumble or slur their words. This is because of the rigidity and muscle weakness of the facial muscles.

6. Changes in Writing

Changes in handwriting are also common in Parkinson’s disease. The person may find it difficult to write or their handwriting may become small and cramped. This is known as micrographia.

7. Depression and Anxiety

Depression and anxiety are common in people with Parkinson’s disease. The diagnosis of Parkinson’s disease can be devastating, and the person may feel overwhelmed or anxious about their future.

Depression can further worsen the symptoms of Parkinson’s disease, making it difficult for the person to cope with their condition.

8. Sleep Disorders

People with Parkinson’s disease may experience sleep disorders like insomnia, sleep apnea or an increased tendency to fall asleep during the day. This is because of the disruption in the natural sleep-wake cycle due to Parkinson’s disease.

9. Eating and Swallowing Difficulties

Eating and swallowing difficulties can be a result of stiffness or muscle weakness in the throat muscles. The person may find it difficult to chew food or may have trouble swallowing. This can lead to difficulty in eating, dehydration and malnutrition.

10. Loss of Sense of Smell

Loss of sense of smell or anosmia is common in Parkinson’s disease. The person may lose their ability to detect certain odors or may not be able to detect any smells at all. This can be a result of the damage to the olfactory nerves in the brain.

If you or someone you know is experiencing these symptoms, it is important to consult with a physician. Early diagnosis and treatment can help manage the symptoms of Parkinson’s disease and improve the quality of life.
