Over one million people suffer from Parkinson’s disease in the United States of America, which is characterized by mobility issues, tremors, rigidity, and loss of balance. Even today, scientists are unable to find the exact cause of the disease. However, they believe that heredity and environmental factors play a crucial role in spurring Parkinson’s disease.

Loss of Dopamine

Our brain works largely with the help of dopamine, which helps the organ control movements. Dopamine is formed in the substantia nigra (black substance). When cells in this part of the brain start dying, they produce less dopamine, ultimately leading to the onset of the disease.


Parkinson’s disease is difficult to diagnose early on. Common symptoms of its onset include loss of smell, vivid dreams, constipation, and small handwriting. Doctors conduct physical tests, of which you must have two of the following symptoms:

  • Slowness of movement
  • Loss of balance
  • The rigidity of limbs or trunk
  • Tremors or shaking
