The International League Against Epilepsy (ILAE) has established a standardized framework for classification, moving beyond simple labels like "grand mal" or "petit mal" to a more precise understanding based on clinical and electroencephalogram (EEG) features. In contrast, a focal seizure might reveal sharp waves or spikes originating from a specific lobe, providing objective evidence that complements the clinical description.
Observing, Describing, and Documenting Seizure Characteristics
Non-motor signs are equally important and can involve changes in sensation, emotion, cognition, or autonomic functions like heart rate or pupil dilation. A generalized tonic-clonic seizure, for example, will show a distinct pattern of high-amplitude, rhythmic waves across the entire cortex.
Variability and Individual Presentation. Clinical Assessment and Patient History A thorough clinical evaluation relies heavily on the details provided by the patient or witnesses.
Observing, Describing, and Documenting Seizure Characteristics
Motor signs include tonic stiffening, clonic jerking, myoclonic sudden jerks, or even a dramatic loss of motor tone known as an atonic seizure. This test records the brain's electrical activity and can capture the characteristic patterns that define different seizure types.
