The initial findings showed that a significant number of patients (23 cases, P = .003) resided in rural areas. Our results showed a higher incidence of Guillain-Barr\u00e9 syndrome in summer and autumn months. No significant difference was observed between the seasonal distribution of acute inflammatory demyelinating polyradiculoneuropathy and acute motor axonal neuropathy subtypes. Antecedent history of pulmonary infections was recorded in 14 children with Guillain-Barr\u00e9 syndrome. Electrophysiological findings revealed a pattern of prolonged F wave latency with reduced persistency, absence of sensory nerve action potential, reduced compound muscle action potential amplitude, prolonged distal motor latency, reduced nerve conduction velocity, and abnormal temporal dispersion or conduction block in most patients with acute inflammatory demyelinating polyradiculoneuropathy. However, reduced compound muscle action potential amplitude, F wave with normal latency and reduced persistency, normal sensory nerve action potential amplitude, normal distal latency, normal sensory nerve conduction velocity, and conduction block or temporal dispersion were observed in most acute motor axonal neuropathy patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The data support a correlation between Guillain-Barr\u00e9 syndrome incidence with seasonal variation and living area.
