Psychogenic non-epileptic seizures (PNES), also referred to as pseudoseizures, non-epileptic attack disorder (NEAD), functional seizures, or dissociative seizures, [2] [3] are episodes resembling an epileptic seizure but without the characteristic electrical discharges associated with epilepsy.
Non-epileptic seizures (NES), also known as pseudoseizures, non-epileptic attack disorder (NEAD), functional seizures, or dissociative seizures, are paroxysmal events that appear similar to an epileptic seizure, but do not involve abnormal, rhythmic discharges of neurons in the brain. [1]
Psychogenic non-epileptic seizures (PNES) are described as neurobehavioral conditions [20] or "psychogenic illnesses" which occur not due to the electrical disturbances in a person's brain but due to mental and emotional stress.

Syncope, psychogenic non-epileptic seizure, migraine aura, transient ischemic attack [3] [8] Treatment: Less than 5 min: Place person on their side, remove nearby dangerous objects More than 5 min: Treat as per status epilepticus [3] [5] [9] Frequency: ≈10% of people (overall worldwide lifetime risk) [10] [11]
Diagnosis of epilepsy can be difficult. A number of other conditions may present very similar signs and symptoms to seizures, including syncope, hyperventilation, migraines, narcolepsy, panic attacks and psychogenic non-epileptic seizures (PNES).
