What it is
Epilepsy is a tendency toward recurrent unprovoked seizures; a single seizure does not always establish epilepsy.
Typical presentation
Seizures may cause loss of awareness, jerking, unusual sensations or brief behavioral arrest rather than always full-body convulsions.
Assessment
A careful account from witnesses, EEG, brain imaging when indicated and exclusion of provoked causes support classification.
Treatment approach
Antiseizure medications are selected for the seizure type and individual circumstances.
Key safety concern
A seizure lasting five minutes or more, repeated seizures without recovery or major injury requires emergency services.

Overview

Symptoms and presentation

Seizures may cause loss of awareness, jerking, unusual sensations or brief behavioral arrest rather than always full-body convulsions.

CLINICAL FEATURES

Presentation and warning signs

The pattern varies and cannot replace an individual assessment.

Clinical overview
Presentation
  • Seizures may cause loss of awareness
  • jerking
  • unusual sensations or brief behavioral arrest rather than always full-body convulsions
Clinical assessment
  • A careful account from witnesses, EEG, brain imaging when indicated and exclusion of provoked causes support classification
  • Interpret results with history and examination
When to seek urgent care
  • A seizure lasting five minutes or more, repeated seizures without recovery or major injury requires emergency services.

Emergency symptoms and clinical severity should be assessed locally.

ASSESSMENT

How the clinical assessment proceeds

Exact investigations depend on the clinical context.

Clinical workflow
1Define the symptom patternSeizures may cause loss of awareness, jerking, unusual sensations or brief behavioral arrest rather than always full-body convulsions.
2Assess disease or alternative causesA careful account from witnesses, EEG, brain imaging when indicated and exclusion of provoked causes support classification.
3Discuss care and monitoringAntiseizure medications are selected for the seizure type and individual circumstances. Safety planning and specialist options are important for drug-resistant epilepsy.

Treatment and management

Antiseizure medications are selected for the seizure type and individual circumstances. Safety planning and specialist options are important for drug-resistant epilepsy.
