Ictal lachrymation, or seizure-induced crying, is rarely seen in children. This study reports a case in an infant with tuberous sclerosis, highlighting a new classification for crying seizures.

Area of Science:

  • Neurology
  • Pediatrics
  • Epileptology

Background:

  • Ictal lachrymation is an uncommon seizure manifestation, particularly in pediatric populations.
  • Tuberous sclerosis complex (TSC) is a genetic disorder that can cause epilepsy.
  • The link between specific seizure types and underlying neurological conditions requires further investigation.

Observation:

  • An infant diagnosed with tuberous sclerosis presented with recurrent seizures.
  • The seizures were characterized by prominent lachrymation (crying) without discernible emotional triggers.
  • Electroencephalography (EEG) revealed an epileptic focus in the left posterior temporal region.

Findings:

  • The reported case represents the first description of ictal lachrymation as a primary seizure manifestation in an infant with TSC.

Related Experiment Videos

  • The findings suggest a potential association between left posterior temporal epileptic activity and reflex tearing.
  • This case challenges the existing understanding of seizure semiology in children.

    • Implications:

    • The study proposes a novel, clinically focused classification system for seizures involving crying.
    • Understanding the neurobiological basis of ictal lachrymation can improve seizure diagnosis and management in children.
    • Further research is warranted to explore the prevalence and mechanisms of crying seizures in pediatric epilepsy.
