Objective:

To profile a set of criteria for the construct of Developmental High-Risk for Severe Mental Illness (DHR-SMI) based on empirically supported and easily collectable features.

Approach:

Key Findings:

• Family psychiatric history is a reliable indicator of heritable vulnerability to SMIs.
• Obstetric complications can disrupt normative brain development, increasing the risk of later cognitive and emotional dysfunctions.
• The premorbid stage of SMIs is characterized by unspecific developmental alterations that may signal underlying neurodevelopmental vulnerabilities.

Interpretation:

The DHR-SMI score can be used as a continuous predictor in survival models, allowing for longitudinal updates as risk factors change over time.

Limitations:

• Polygenic risk scores have limited clinical utility due to modest predictive accuracy.
• Long-term prognostic outcomes for the ESSENCE construct are lacking.

Conclusion:

The study highlights the importance of identifying early neurodevelopmental manifestations that may be linked to later severe mental illnesses.
