Parkinson’s Disease

What is Parkinson’s Disease?

Parkinson’s disease is a progressive disorder of the nervous system that affects movement. It occurs when the nerve cells present in the brain do not produce enough of the brain chemical, known as dopamine (one that is used to send messages to parts of the brain that control movement and coordination). As this disease develops, dopamine inside the brain decreases, making it hard to control movement. It is a chronic disorder for many, as the symptoms continue to worsen over time.


The following are the symptoms and signs of this disease:

  • Tremor, rigidity, slowness of movement, and postural instability.
  • Bradykinesia (slow movement or reduction of spontaneous movement).
  • Rigidity in limbs, neck, and trunk.
  • Pain and postural instability.
  • Dementia.
  • Excessive sweating, constipation, and gastrointestinal dysmotility.


The cause of the disease is unknown, although environmental and genetic factors appear to play a slight role. The probable causes of the disease are:

  • Genetic variations.
  • Environmental factors.
  • Exposure to certain toxins.


The risks factors of this disease are:

  • Age: people around 60 years of age are at an increased risk.
  • Heredity.
  • Exposure to certain toxins.
  • Gender: Males are most likely to get affected.


The causes of the disease are not exactly known, but to prevent the occurrence of this disease, there are certain things one should take care of:

  • Reducing consumption of caffeine in coffee, cola, and tea.
  • Consumption of green tea.
  • Aerobic exercises.
