Seizures induced by thinking

A J Wilkins, B Zifkin, F Andermann

    Annals of Neurology
    |June 1, 1982

    Summary
    This summary is machine-generated.

    Mental arithmetic, particularly multiplication and division, can trigger generalized epileptiform activity in some individuals with epilepsy. This suggests a potential link between specific cognitive tasks and seizure precipitation.

    Area of Science:

    • Neuroscience
    • Epileptology
    • Cognitive Neurology

    Background:

    • Generalized convulsions can be triggered by specific stimuli.
    • Understanding the relationship between cognitive processes and epileptic activity is crucial for diagnosis and treatment.

    Observation:

    • A patient experienced seizures reliably precipitated by mental arithmetic.
    • Electroencephalogram (EEG) showed generalized epileptiform activity during mental arithmetic tasks.
    • Specific tasks like multiplication, division, and spatial manipulation were strongly associated with EEG discharges.

    Findings:

    • Addition and subtraction tasks of similar difficulty did not elicit significant EEG discharges.
    • Short-term memory tasks, such as digit repetition, were not associated with paroxysmal EEG activity.

  • Generalized epilepsy may involve focal dysfunction, similar to pattern-sensitive epilepsy.

    • Implications:

    • This case highlights a specific cognitive trigger for generalized epilepsy.
    • Further research into the neural basis of calculation-induced seizures is warranted.
    • Findings may inform diagnostic approaches and personalized treatment strategies for epilepsy.
