The "jerks": mass hysteria or epilepsy?

Area of Science:

• Neurology
• Psychiatry
• Sociology

Background:

• Hysterical epidemics of epilepsy are documented across cultures.
• The 19th and 20th centuries in the United States saw a unique religious movement.

Observation:

• This religious movement was the context for phenomena termed "the jerks."
• Various manifestations of "the jerks" were observed and described.

Findings:

• Observed "jerks" included "dancing exercise," "barking exercise," "laughing exercise," "running exercise," and "singing exercise."
• These phenomena represent a culturally specific manifestation of collective behavior.

Implications:

• Understanding these events provides insight into the interplay of religion, culture, and neurological or psychological phenomena.
• Further research can explore the historical and social factors contributing to such "epidemics."
• This case highlights the importance of considering cultural context in diagnosing and understanding "epilepsy" and related conditions.
