    Spike abnormalities on electroencephalogram (EEG) EEGs are common in nonepileptic patients, especially children. These findings suggest specific EEG patterns and clinical factors may predict seizure development.

    Area of Science:

    • Neurology
    • Clinical Neurophysiology

    Background:

    • Spike abnormalities on electroencephalogram (EEG) are observed in patients without epilepsy.
    • Understanding the incidence and characteristics of these abnormalities is crucial for accurate diagnosis and prognosis.

    Purpose of the Study:

    • To investigate the incidence and characteristics of spike abnormalities in nonepileptic patients.
    • To identify clinical and EEG factors associated with the development of epileptic seizures.

    Main Methods:

    • Retrospective analysis of EEG data from 202 nonepileptic patients with at least two instances of spike abnormalities.
    • Comparison of clinical symptoms and family history with control groups.
    • Follow-up assessment for the development of epileptic seizures.

    Main Results:

    • The incidence of spike abnormalities in nonepileptic patients was 8.1%.
    • The majority of affected patients (90%) were under 19 years old.
    • Commonly observed EEG abnormalities included diffuse irregular slow wave bursts with spike, positive spikes, and small spikes.
    • Headache, dizziness, vomiting, and abdominal pain were more frequent in patients with spike abnormalities.
    • Three patients developed epileptic seizures during follow-up, often exhibiting more specific EEG abnormalities.

    Conclusions:

    • Mild paroxysmal EEG abnormalities are frequent in nonepileptic individuals, particularly children.
    • Age at onset before 9, specific clinical symptoms, and a positive family history of seizures are important predictors for the manifestation of clinical seizures.
