Disease at a Glance: Parkinson’s Disease

Parkinson’s Disease is a chronic and progressive disorder of the nervous system – i.e. the symptoms continue and worsen over time. Although the exact cause of the disease is not fully known, it’s believed to be the result of damaged neurons or nerve cells in an area of the brain called the substantia nigra.

 

These neurons produce a chemical called dopamine, which is responsible for smooth and coordinated muscle movements. As the disease progresses, the amount of dopamine produced in the brain decreases, leaving the patient unable to control movements normally.

 

Parkinson’s Disease is more common in the elderly, with most cases occurring after the age of 50. In 4-5 per cent of cases, however, the disease process may start earlier. Men have a 50 per cent higher risk of developing the disease than women.

 

Common Symptoms

Early Signs: Mild tremor or slight feeling of stiffness & dragging of one foot
Problems with balance & walking
Drooling & difficulty in swallowing
Mask-like fixed expressionless face
Finger-thumb rubbing (known as pill-rolling movement)
Difficulty in writing 
Stooped posture
Slow blinking of the eyelids

 

The symptoms are usually mild at the beginning, with manifestations of mild tremor or slight feeling of stiffness and dragging of one foot. The primary symptoms may vary from person to person – for example, many people experience tremor as their primary symptom, while others may not have tremors, but may have problems with balance.

 

Over time, the symptoms include slow blinking of the eyelids, difficulty in swallowing, drooling, problems with balance & walking, a mask-like fixed expressionless face (called Parkinsonian face), difficulty in writing, severe tremors, finger-thumb rubbing (known as pill-rolling movement), slow monotone voice and stooped posture. Slow dragging of feet with a stooping posture give an impression that the person is likely to fall down while walking. Finally, the disease advances to a stage where patients experience cognitive and behavioural problems like dementia, depression, etc.

 

There is no known cure for Parkinson’s Disease, but medications are prescribed to control the symptoms. Physiotherapy and lifestyle changes may also be recommended.
