Parkinson’s disease (PD) affects the nerve cells in the brain that produce dopamine. It is the second most common age-related neurodegenerative disorder after Alzheimer’s disease.

The number of PD patients in the world more than doubled between 1990 and 2016, from 2.5 million to 6.1 million. A relatively conservative projected doubling of the number of patients over the next 30 years would yield more than 12 million patients worldwide by about 2050.

Even though it is so prevalent, scientists are still unsure what causes it. Doctors only prescribe symptomatic treatments for the management of this condition.

Nerve Cell


An estimated seven to 10 million people worldwide have Parkinson’s disease.


Parkinson's disease is caused by loss of nerve cells in part of the brain known as 'substantia nigra'.

When these vital cells begin to deteriorate, it causes a reduction of dopamine – a chemical that plays a key role in controlling and coordinating movement in the body.

This damage can lead to telltale tremors that people most typically associate with the disease, where the hands, arms, legs, lips, jaw or tongue become shaky when they are not in use.

The exact reason that causes deterioration of nerve cells is unknown, although research points to a combination of genetic and environmental factors. This disease is more prevalent in men aged over 50.

Evidence that Parkinson’s disease may start off in the gut is mounting, according to new research showing proteins (abnormally folded alpha-synuclein) thought to play a key role in the disease can spread from the gastrointestinal tract to the brain.

“It supports and really provides the first experimental evidence that Parkinson’s disease can start in the gut and go up the vagus nerve,” said Ted Dawson, professor of neurology at the Johns Hopkins University school of medicine and co-author of the research.


Alpha-synuclein, a protein, accumulates in the brains of people with Parkinson’s disease.


It can be hard to tell if you or a loved one has PD. The primary symptoms are all related to voluntary and involuntary motor function and usually start on one side of the body. Symptoms are mild at first and will progress over time.

Loss of sense of smell, restless nights, muscle stiffness, incontinence, constipation, anxiety, difficulty balancing, nerve pain and depression could be early signs of this condition.

One often overlooked early sign is a loss of smell. Research conducted by the University of Auckland identified an anatomical link for the loss of smell in Parkinson’s disease.

The diagnosis of Parkinson’s disease is challenging before patients develop motor symptoms such as tremor or other movement abnormalities.... By this time, significant neurological damage has occurred. Usually this is irreversible.

Medicines prescribed for Parkinson's include:

  • drugs that increase the level of dopamine in the brain,
  • drugs that affect other brain chemicals in the body,
  • drugs that help control non-motor symptoms.

Combination of these medicines help patients curb the uncontrollable tremors, muscle stiffness and balance problems temporarily.

Once-daily treatment of opicapone, added to levodopa, has been found to increase the length of ON-periods in patients with Parkinson's disease.

Goal-oriented physical activity/exercise can lead to significant improvement in the ability to walk, and in the dexterity of hands/fingers.


Eat fresh vegetables. Go organic. Include foods containing omega-3 fatty acids in your diet. Consume raw vegetables. Meditate daily.

Ensure that you are getting enough vitamin D3. Drink green tea. Do yoga daily. Include foods that contain CoQ10 in your diet. Spinach, broccoli and cauliflower are rich in this antioxidant.

Ensure that stress does not have negative effect on your body and mind. Heartfulness way of life helps you in this endeavor.
