CLINICAL ATLAS · AREA 04

Seizure / EEG / spells

Open the exact information count, clinical terms, source boundaries, and next measurement for this area. Counts describe information availability—not prevalence.

HOW TO READ THE COUNTSOne key applies to all 15 areas.Each area places all 65 connected people into one mutually exclusive category. These groups describe the information available; they are not prevalence estimates.

A finding is reported
At least one feature is reported, without an explicitly normal or uncertain item in the same area.
A finding plus normal or uncertain information
A reported feature appears alongside an explicitly normal result or an unresolved observation.
Only explicitly normal results
The available information records a normal or negative result without a reported feature in the area.
Only uncertain information
An observation remains unresolved and no confirmed feature is recorded in the area.
Area not addressed
The available information does not answer this broad area; this is not a negative result.

Information available for Seizure / EEG / spells

What is electrographic, what is observed, and what remains unresolved?

Seizure diagnoses, EEG architecture, background organization, sleep captured, non-epileptiform spells, event awareness, recovery, and cardiac channel context.

WHAT THE INFORMATION SHOWS

This area includes established electroclinical seizures, abnormal EEG background without an epileptiform event, captured nonepileptic movements, and unresolved spells.

HOW TO READ IT

Event phenotype, EEG background, captured electrographic correlate, sleep state, and cardiorespiratory physiology answer different questions.

NEXT MEASUREMENT

Define the representative event, capture sleep and the event when indicated, document recovery, and align EEG with video, ECG, oxygenation, or other physiology supported by the phenotype.

Clinical terms found in the available information

Seizure phenotypes

  • absence or brief generalized seizures
  • generalized tonic-clonic or convulsive events
  • focal or multifocal events
  • spasms
  • neonatal or infant events

EEG architecture

  • background slowing or disorganization
  • posterior dominant rhythm
  • interictal generalized, focal, or multifocal discharges
  • sleep-stage acquisition
  • activation and photic response

Spells & comparison findings

  • staring or shutdown-like events
  • nocturnal or awakening-linked events
  • typical movements captured without EEG correlate
  • cardiac, oxygenation, or autonomic overlap
  • post-event confusion, sleep, weakness, or recovery
