Objective:

To report a case of dissociative amnesia with fugue following a suicide attempt and to explore the intersection of suicidality and identity disruption, highlighting clinical implications.

Key Findings:

• The patient experienced selective retrograde autobiographical amnesia with intact semantic and procedural memory, highlighting the complexity of identity disruption.
• Gradual recovery of autobiographical fragments occurred during a three-week psychiatric admission, though full identity restoration was not achieved.
• Dissociative amnesia with fugue should be considered in cases of post-self-harm amnesia with preserved cognition, emphasizing the need for accurate diagnosis.

Interpretation:

The case illustrates a rare intersection of suicidality and dissociative identity disruption, supporting the retrieval inhibition model of dissociative amnesia and its implications for treatment.

Limitations:

• No post-discharge follow-up data were available, limiting prognostic conclusions and potential biases in the case study approach.
• The rarity of the condition poses challenges for broader applicability of findings, necessitating further research.

Conclusion:

This case provides an educational framework for understanding the interaction between identity, memory, and self-preservation in acute psychiatric emergencies, underscoring the need for further research.
