Can the DSM-5 framework enhance the diagnosis of MCI?

Area of Science:

• Neurology
• Psychiatry
• Clinical Diagnostics

Background:

• The field of mild cognitive impairment (MCI) is evolving with ongoing efforts to update diagnostic criteria.
• Existing diagnostic frameworks may present challenges in consistency, redundancy, and ambiguity.

Purpose of the Study:

• To propose the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) framework as a model for updating MCI diagnostic criteria.
• To enhance the clarity, consistency, and clinical utility of MCI diagnoses.

Main Methods:

• Conceptual analysis of the DSM-5 framework's application to MCI diagnosis.
• Evaluation of how the DSM-5 framework can improve diagnostic rigor and reliability.

Main Results:

• The DSM-5 framework can help differentiate causes from consequences in MCI.
• It promotes internal consistency, reduces ambiguity, and enhances diagnostic reliability for clinicians and researchers.
• The framework supports distinguishing core features, subtypes, specifiers, and risk factors for more homogeneous subgroups.

Conclusions:

• Adopting a DSM-5-like framework for MCI can improve conceptual rigor and diagnostic utility.
• Systematic incorporation of new knowledge into such a framework can enhance predictive value.
• This approach facilitates the development of more precise and clinically useful MCI diagnostic criteria.
