Parkinson’s Disease

Parkinson’s Disease is characterized as a slowly progressive, degenerative movement disorder that affects the central nervous system causing unintended, uncontrollable movements like tremors, shaking, stiffness, and difficulty with coordination and balance. Most of the difficulties are caused due to the impaired neurons producing dopamine. Dopamine is a chemical messenger that sends signals from parts of the brain that controls and coordinate movements.

Symptoms of Parkinson's are as below:

  • Tremor
  • Slow movements
  • Change in handwriting
  • Difficulty moving or walking
  • Slurred, soft speech
  • Sleep disorders
  • Expressionless face
  • Impaired posture
  • Sexual dysfunction
  • Dizziness or fainting


  • Loss of nerve cells that produce dopamine
  • Genetics
  • Environmental factors such as the effect of industrial pollution

Frequently Asked Questions

Do people with Parkinson’s Disease have trouble sleeping?

Ongoing research shows that Parkinson's disease may disrupt sleep-wake cycles due to chemicals in the brain. This may cause people with Parkinson's to get less restful sleep. Certain therapies such as medication and deep brain stimulation, may help with this.

Is Parkinson’s disease fatal?

Despite misconceptions, Parkinson’s disease itself does not shorten one’s life expectancy. However, late-stage symptoms such as immobility, poor balance and difficulty swallowing, place patients at a higher risk for fatal complications which include fractured hips, pneumonia, etc.

Who is more likely to develop Parkinson's disease, men or women?

Parkinson’s disease affects both men and women, though 50% more men are affected than women.
