Hippocrates

Men think epilepsy divine, merely because they do not understand it. We will one day understand what causes it, and then cease to call it divine. And so it is with everything in the universe.

Reflex Seizures

Italiano et al, 2014:

Reflex seizures are:

    • epileptic events
    • triggered by specific motor, sensory, or cognitive stimulation
    • can be generalized or focal

Italiano et al, 2016:

Reflex seizures in humans:

    • visual in 10% children, 5% adults
    • reading can be familial
    • occur in a variety of animals

Each patient tends to have just 1 type of reflex seizure but may have other seizures as well.

Reflex Seizures

What & How

A seizure is...

01

a transient (fleeting) occurrence of

symptoms (things the patient feels) and/or sign (things witnesses see)

due to abnormal excessive or synchronous neuronal activity in the brain.

Reflex Seizures

What & How

A reflex seizure is ...

01

a transient (fleeting) occurrence of

due to abnormal excessive or synchronous neuronal activity in the brain.

elicited by a very specific trigger, often in a specific environment with other conditional changes.

Reflex Seizures

What & How

The only reflex seizure included in the 2021 ILAE nosology is...

01

EwRIS, epilepsy with reading induced seizures

the only reflex seizure to have consistent electroclinical features, etiologies, and prognosis.

Reflex Seizures & Epilepsies

Both must be elicited by a specific trigger consistently.

Both must fit the definition of seizures and/or epilepsy.

    • Reflex Seizures

Hanif and Musick, 2021 - epileptic events that are objectively and consistently elicited in response to a specific stimulus or by a patient activity.

    • Reflex Epilepsy

Hanif and Musick, 2021 - specific syndrome in which ALL seizures are elicited by sensory stimuli.

Thank You

For 25 years, I’ve enjoyed ASET and Neurodiagnostics.

For more than 15 years, I’ve loved reading and writing for our journal. And for nearly a year, I’ve been enthralled in mentoring board prep through my own business. You never know where this can take you. Thanks!!
