[Future standards in diagnosing Parkinson syndrome]

Area of Science:

• Neurology
• Medical Diagnostics

Background:

• Idiopathic Parkinson's syndrome (PD) diagnosis traditionally uses the British Brain Bank Criteria.
• These criteria require bradykinesia plus at least one cardinal symptom (tremor, rigidity, postural instability).
• Postural instability is not useful for early PD diagnosis as it appears in advanced stages.

Purpose of the Study:

• To highlight early diagnostic signs of Parkinson's syndrome.
• To discuss the utility of various diagnostic methods for Parkinson's.
• To suggest future diagnostic advancements for Parkinson's.

Main Methods:

• Review of current diagnostic criteria for Parkinson's syndrome.
• Identification of early clinical indicators of PD.
• Evaluation of supportive diagnostic tools including levodopa tests, SPECT, PET, CT, and MRI.
• Anticipation of future genetic diagnostic technologies.

Main Results:

• Early signs of Parkinson's include hyposmia, constipation, REM sleep behavior disorder, and depression.
• Clinical diagnosis remains primary, supported by levodopa testing.
• Neuroimaging techniques like SPECT and PET are valuable for unclear cases.
• Genetic testing is expected to become available for specific patient groups.

Conclusions:

• Early diagnosis of Parkinson's syndrome relies on recognizing subtle early signs beyond traditional criteria.
• While clinical assessment is central, advanced imaging and potential future genetic tests offer crucial support.
• A cranial CT or MRI is recommended for all Parkinson's patients at some point.
