Paroxysmal non-epileptic events in infancy: five cases with typical features

Area of Science:

• Pediatric Neurology
• Clinical Diagnostics

Background:

• Diagnosing paroxysmal non-epileptic events in infants and toddlers presents significant challenges for pediatricians and child neurologists.
• Parental concern over unusual infant movements often leads to immediate consultation with general practitioners, frequently with a suspicion of epilepsy.

Purpose of the Study:

• To identify the primary reasons for referral of infants and toddlers suspected of having epilepsy.
• To describe the characteristic features of five common non-epileptic paroxysmal events in early childhood using visual aids.
• To emphasize the diagnostic value of detailed patient history in distinguishing epileptic from non-epileptic events.

Main Methods:

• Retrospective review of five infants/toddlers (aged 1-30 months) initially referred with suspected epilepsy.
• Analysis of clinical presentation, focusing on history and observed paroxysmal events.
• Inclusion of images and video sequences to illustrate typical features of non-epileptic events.

Main Results:

• None of the five investigated infants/toddlers were ultimately diagnosed with epilepsy.
• Detailed historical information proved highly significant in differentiating epileptic from non-epileptic paroxysmal events.
• Identified non-epileptic events included benign neonatal sleep myoclonus, jitteriness, shuddering attacks, paroxysmal tonic upgaze, and infantile masturbation.

Conclusions:

• A thorough patient history is a cornerstone in the differential diagnosis of paroxysmal events in early childhood.
• Accurate historical assessment can prevent unnecessary diagnostic procedures, such as video-electroencephalogram (EEG) examinations.
• Video-EEG is reserved for cases where epilepsy remains a strong clinical suspicion.
