Minimal Emotional Dysfunctions (MED) in Personality Disorders: A Narrative Review

Area of Science:

• Psychiatry
• Clinical Psychology
• Emotional Science

Background:

• Emotional dysfunctions are central to personality disorders (PDs).
• Existing models may not fully capture the complexity of these emotional disturbances.
• A systematic framework is needed to understand emotional deficits in PDs.

Purpose of the Study:

• To review empirical research on emotional dysfunctions in PDs.
• To classify these dysfunctions using the Minimal Emotional Dysfunctions (MED) model.
• To explore the utility of the MED model and ICD-11 dimensional framework for PDs.

Main Methods:

• Narrative review of empirical studies on emotional dysfunctions in PDs.
• Selective literature search to identify relevant research.
• Synthesis of findings within the MED model's classification system.

Main Results:

• Emotional dysfunctions manifest in distinct patterns across different PDs.
• These dysfunctions can be categorized into affect modulation, production, and quality issues within the MED model.
• Emotional disturbances significantly contribute to cognitive and interpersonal difficulties in PDs.

Conclusions:

• Emotional dysfunctions are a core feature of PDs, not merely secondary symptoms.
• The MED model provides a valuable framework for understanding and classifying emotional disturbances in PDs.
• A dimensional approach, like that in ICD-11 and the MED model, enhances understanding of PD emotional complexity.
