Spike location and probability of epilepsy

Spike location and probability of epilepsy
Probability: Most often associated with:
High probability of epilepsy (>85%):
Anterior-mid temporal spikes* Mesial temporal lobe epilepsy
Midline spikes Tonic-clonic seizures
Hypsarhythmia Infantile spasms (West syndrome)
Slow spike-wave Lennox-Gastaut syndrome
Generalized paroxysmal fast activity Lennox-Gastaut syndrome
Moderate probability of epilepsy (<75%):
Frontal spikesΔ Frontal lobe epilepsy
Generalized spike-wave (≥3 Hz) Absence epilepsy (3 Hz; CAE, JAE), juvenile myoclonic epilepsy (>3 Hz), and other primary generalized epilepsies
Centro-temporal spikes◊ Benign rolandic epilepsy of childhoood (BREC)
Occipital spikes§ Benign focal epilepsy of childhood (Gastaut and Panayiotopolous syndromes: the 2 variants of CEOP)
Photoparoxysmal response Primary generalized epilepsy

CAE: childhood absence epilepsy; JAE: juvenile absence epilepsy; BECTS: benign focal epilepsy of childhood with centrotemporal spikes; BREC: benign rolandic epilepsy of childhood; CEOP: childhood epilepsy with occipital paroxysms.

* >90% probability of seizures/epilepsy (adults)[1].

¶ 76-91% probability of seizures/epilepsy (children)[2].

Δ ~75% probability of seizures/epilepsy (children)[3].

◊ ~40% probability of seizures/epilepsy (children)[3].

§ 50% probability of seizures/epilepsy (children)[3].
