MICEmi: A method to identify cognitive endophenotypes of mental illnesses

Area of Science:

• Neuroscience
• Psychiatry
• Genetics

Background:

• Neurocognitive endophenotypes are crucial for understanding mental illnesses (MIs), aiding in early diagnosis, risk identification, and treatment development.
• A lack of standardized methods hinders the consistent identification and application of these endophenotypes in MI research.
• This study addresses the need for a systematic approach to defining cognitive endophenotypes in mental illness.

Approach:

• A 14-expert working group employed a scoping review methodology to develop a novel method.
• The proposed method incorporates a scoring template with five criteria and indicators for endophenotype assessment.
• A verification strategy and a decision tree were designed to guide the identification process.

Key Points:

• The developed method provides a structured framework for identifying neurocognitive endophenotypes.
• It includes specific criteria, verification strategies, and a decision tree to ensure consistent application.
• This systematic approach aims to enhance the reliability and validity of endophenotype research in mental illnesses.

Conclusions:

• The presented method offers a standardized approach to identifying endophenotypes in mental illness research.
• Ongoing work includes external validation to confirm the method's applicability in future studies.
• This research lays the groundwork for advancing the understanding and treatment of mental illnesses through neurocognitive endophenotyping.
