Medical Conditions

Parkinson’s Disease is the second commonest neuro-degenerative disease after Alzheimer’s Disease, characterized by rest tremors, rigidity, bradykinesia (slowing down of movements) and disturbance of gait or postural instability.


• The cardinal symptoms are slowing down of all movements (bradykinesia), rest tremors, rigidity and gait disturbance/ postural instability.
• Other motor features include micrographia (change in handwriting), masked facies (reduced facial expressions), reduced eye blink, soft voice, difficulty in swallowing, freezing.
• Nonmotor features include anosmia (loss of smell sensation), sensory disturbances , mood disorders, sleep disturbances, cognitive impairment, sexual dysfunction, gastrointestinal and genitourinary disturbances.


• Most (~85-90%) cases of Parkinson’s occur sporadically and are of unknown cause.
• Studies suggest that environmental factors are likely to play the more important role in patients older than 50 years and genetics play a bigger role I’m younger patients .
• Increased risk is seen with exposure to pesticides and drinking well water.
• MPTP, a byproduct of illicit manufacture of a heroin like drug was shown to cause a Parkinson’s like syndrome.
• 10-15% cases are familial in origin and multiple genetic mutations have been identified.


• Medical therapy with drugs such a Levodopa, Dopamine agonists, MAO-B inhibitors, COMT Inhibitors and other medical therapies.
• Neuroprotection with agents like Selegiline, coenzyme Q10 etc for disease modifying effects.
• Surgical treatment by Deep Brain Stimulation.
• Non pharmacologic treatment:
• Exercise with full range of active and passive movements has been shown to improve and maintain function in Parkinson’s patients.
• Formal physical therapy is necessary unless there is specific indication.
