[Non-epileptic disorders in infancy and adolescence]

Area of Science:

• Neurology
• Psychiatry
• Clinical Medicine

Background:

• Epilepsy impacts 0.5% of the population, with a significant portion of referrals to epilepsy services presenting non-epileptic events.
• Approximately 25% of patients exhibit paroxysmal clinical events that mimic epileptic seizures but stem from non-epileptic causes.
• Non-epileptic seizures are broadly categorized into psychogenic events (without a medical cause, linked to psychological issues) and those of physiological origin.

Observation:

• Non-epileptic events manifest as paroxysmal or repetitive behaviors that closely resemble epileptic seizures.
• These events can involve motor activities, sensory or emotional alterations, or impairment of consciousness.
• Distinguishing between epileptic and non-epileptic seizures is challenging due to overlapping clinical presentations.

Findings:

• This study reviews and presents clinical cases of major non-epileptic physiological events, including sleep disorders, movement disorders, and hypoxic-ischemic phenomena.
• It also examines psychogenic non-epileptic events such as somatoform disorders, factitious disorders, and anxiety disorders.
• The review highlights the diverse origins and presentations of non-epileptic events.

Implications:

• Accurate diagnosis of non-epileptic seizures is vital for patient care.
• Correct diagnosis prevents unnecessary diagnostic tests and iatrogenic therapies associated with epilepsy treatment.
• Understanding the distinction aids in appropriate management strategies for patients with non-epileptic events.
