• The patient exhibited distinct identity states that alternately controlled her behavior.

Findings:

• The diagnosis of DID is relatively uncommon in Danish clinical practice and faces ongoing debate regarding its validity.
• Empirical research increasingly supports DID as a valid psychiatric disorder, yet underdiagnosis or misdiagnosis remains a concern.

Implications:

• This case highlights the challenges in diagnosing and recognizing Dissociative Identity Disorder, particularly in adolescent populations.
• Further research and clinical awareness are crucial to improve the accurate identification and management of DID, addressing potential underdiagnosis and misdiagnosis in psychiatric practice.
