Amnesia or fugue state: a diagnostic dilemma

Area of Science:

• Neuroscience
• Psychiatry
• Psychology

Background:

• Amnesia presents a diagnostic challenge, often necessitating the exclusion of organic etiologies.
• Psychogenic amnesia, while less common than organic forms, requires careful clinical consideration.

Observation:

• A 16-year-old male presented with sudden-onset total retrograde amnesia.
• Extensive medical workup revealed no evidence of toxic-metabolic, epileptic, infectious, inflammatory, traumatic, or neoplastic causes.

Findings:

• The patient was diagnosed with a psychogenic fugue state.
• Memory function spontaneously resolved over a period of several days.

Implications:

• This case underscores the necessity of including psychogenic fugue states in the differential diagnosis for amnesia, particularly in adolescents.
• Further research into the neurobiological underpinnings of psychogenic amnesia may elucidate its mechanisms and improve diagnostic accuracy.
