Differential diagnosis of epileptic seizures in infancy including the neonatal period

Area of Science:

• Neonatal neurology
• Pediatric epilepsy
• Differential diagnosis

Background:

• Accurate diagnosis of neonatal seizures is vital for prognosis and management.
• Non-epileptic movements in neonates and infants can mimic seizures.
• Distinguishing seizures from other conditions avoids overtreatment and misdiagnosis.

Purpose of the Study:

• To highlight key clinical features differentiating epileptic seizures from non-epileptic events in infants.
• To discuss the management and prognosis of these conditions.
• To aid clinicians in accurate early-life neurological diagnosis.

Main Methods:

• Review of clinical features of common non-epileptic infant movements.
• Comparison with characteristics of epileptic seizures.
• Discussion of rare neurological disorders presenting with similar symptoms.

Main Results:

• Identified physiological movements (e.g., tremor, sleep myoclonus, shuddering) that do not stem from brain electrical activity.
• Highlighted rare neurological diagnoses (e.g., hyperekplexia, paroxysmal extreme pain disorder, alternating hemiplegia of childhood) with distinct prognoses.
• Emphasized the importance of clinical observation in differential diagnosis.

Conclusions:

• Clinical differentiation is key to avoid misdiagnosis and inappropriate treatment of infant movement disorders.
• Understanding the spectrum of neonatal and infant movements improves patient outcomes.
• Accurate diagnosis guides appropriate management and prognosis for infants with neurological conditions.
