Comparing a Single Clinician Versus a Multidisciplinary Consensus Conference Approach for Dementia Diagnostics

Area of Science:

• Neurology
• Geriatrics
• Diagnostic Medicine

Background:

• Limited evidence-based guidelines exist for optimal dementia diagnostic evaluation.
• This lack of standardization hinders consistent patient workup across healthcare settings and internationally.

Purpose of the Study:

• To compare the diagnostic performance of a multidisciplinary consensus conference against a single clinician approach for dementia diagnostics.

Main Methods:

• Prospective study involving 457 patients with suspected cognitive decline from two European memory clinics.
• Independent diagnostic evaluations by a single clinician and a multidisciplinary consensus conference.
• Reference diagnosis established by an expert panel and 12-24 month follow-up.

Main Results:

• A 12.5% discrepancy in syndrome diagnosis and 22.3% in etiological diagnosis between single clinician and consensus conference.
• Consensus conference showed significantly higher accuracy in etiological diagnosis, particularly for Mild Cognitive Impairment (MCI).
• Clinician confidence in etiological diagnosis was significantly higher with the consensus conference, especially for frontotemporal dementia.

Conclusions:

• Multidisciplinary consensus conferences demonstrate superior diagnostic accuracy and increased clinician confidence in dementia evaluation.
• Emphasizes the importance of a collaborative, multidisciplinary approach for dementia diagnostics, especially in the MCI stage.
