Diagnosis of Parkinson's Disease

Diagnosis of Parkinson's Disease
       How to diagnose Parkinson's Disease? Doctors must to know it. There are ways how to diagnose this disease. The diagnosis of Parkinson's disease is confirmed by the following criterias:

1. Clinically
• Achieved 2 of 3 cardinal signs of motor disorders: tremor, rigidity, bradykinesia or
• 3 of 4 motor signs: tremor, rigidity, postural instability and bradykinesia.

2.  Koller's criterias
• It was found 2 of the 3 cardinal signs of motor disorders: tremor at rest or disruption
postural reflexes, rigidity, bradykinesia lasting 1 year or more.
• The response to levodopa therapy was given until repairs are (at least
1,000 mg / day for 1 month) and long repair 1 year or more.

3. Criteria of Gelb & Gilman
• Symptoms of group A (typical for Parkinson's disease) consists of:
1) Resting tremor
2) Bradykinesia
3) Rigidity
4) The beginning of asymmetrical
• Clinical symptoms of group B (early symptoms uncommon), alternative diagnoses, consisting of:
1) postural instability are prominent in the first 3 years
2)  Can not move at all  phenomenon(freezing) in the first 3 years
3) Hallucination (unrelated with the treatment) in the first 3 years
4) Dementia before motor symptoms in the first year.

      The diagnosis of "possible": there are at least two of the symptoms of group A where one of them is a tremor or bradikinesia and there are no symptoms group B, duration of symptoms is less than 3 years old with clear response to levodopa or dopamine agonists.
       The diagnosis of "probable": there are at least 3 of the 4 symptoms of group A, and there are no symptoms of group B, duration of disease for at least 3 years and the response clear to levodopa or dopamine agonists.
    The diagnosis of "definite": meets all criteria of probable and inspection histopathologic positive.
