Early diagnosis in Parkinson's disease

Area of Science:

• Neurology
• Movement Disorders
• Diagnostic Medicine

Background:

• Early Parkinson's disease (PD) presents with subtle clinical symptoms, complicating timely diagnosis.
• Current diagnostic approaches may lack the sensitivity to detect incipient PD.
• There is a need for objective methods to supplement clinical evaluation in early PD detection.

Purpose of the Study:

• To explore instrumental and biochemical methods for enhancing early Parkinson's disease diagnosis.
• To assess the utility of kinesiologic methods and advanced imaging in identifying subtle PD signs.
• To highlight the current lack of specific biochemical markers for early PD and the need for further research.

Main Methods:

• Utilizing kinesiologic methods, specifically the Motor Performance Test, for sensitive detection of clinical signs.
• Employing advanced imaging techniques, such as Positron Emission Tomography (PET), as diagnostic tools.
• Reviewing the current status of biochemical markers for early PD diagnosis.

Main Results:

• Kinesiologic methods, like the Motor Performance Test, offer a more sensitive approach to detecting early PD symptoms.
• Positron Emission Tomography (PET) is identified as a valuable imaging tool for assessing neurodegenerative changes in PD.
• No specific biochemical markers for early PD diagnosis have been established to date.

Conclusions:

• Instrumental methods, including kinesiologic tests and PET imaging, show potential for improving early Parkinson's disease diagnosis.
• Further field studies are essential to validate the sensitivity and reliability of various instrumental and biochemical methods for early PD detection.
• The development of specific biochemical markers remains a critical unmet need in the early diagnosis of Parkinson's disease.
