Triggers and Clinical Presentations of Functional Neurological Disorders: Lessons from World War 1

Area of Science:

• Psychiatry and Psychology
• Medical History
• Neuroscience

Background:

• Functional neurological and somatic symptom disorders are a significant area of medical discussion.
• Understanding these disorders requires examining stress, life events, and cultural influences.

Purpose of the Study:

• To analyze historical case records of functional somatic disorders from World War 1.
• To compare symptom profiles and diagnoses between civilian and military patients.
• To identify triggers and understand their influence on symptom presentation.

Main Methods:

• Analysis of 937 case records from London-based civilian and military patients during WWI.
• Statistical comparison (chi-squared tests) of symptom profiles and diagnoses between groups.
• Identification and categorization of triggering events.

Main Results:

• Soldiers showed higher rates of paralysis and speech disturbances compared to civilians.
• Female patients reported higher rates of pain and general somatic symptoms.
• Triggers included combat, accidents, physical illness, and work stress, influencing symptom expression; patterns of comorbidity and symptom clusters resembled modern cohorts.

Conclusions:

• Historical analysis of functional neurological and somatic symptom disorders reveals consistent patterns over time.
• Understanding past presentations and trajectories can inform current treatment and research.
• The study highlights the enduring nature of these disorders and their triggers.
