Continuous critical care EEG monitoring has become an invaluable study in the diagnosis and treatment of subclinical seizures and nonconvulsive status epilepticus. Interictal and ictal EEG findings also underlie the classification of seizures and epilepsy. Because of the paroxysmal nature of seizure disorders, interictal epileptiform discharges, such as spikes and sharp waves, are often used to support the diagnosis of epilepsy when a habitual seizure is not captured by EEG.
The physiologic basis of EEG and intracranial EEG studies is also discussed.ĮEG is widely used in clinical practice. This article provides an overview of common EEG findings in epileptic disorders.
Epilepsy is a heterogeneous disorder that is often associated with abnormal electroencephalogram (EEG) findings.
