“Selfie-Epilepsy”: A Novel Photosensitivity. Seizure.
In press.
Abstract
Purpose
Photosensitivity is a well-described phenomenon; affecting a
relatively small proportion of individuals with epilepsy. Typically people with
photosensitive epilepsies are at risk of seizures induced by shimmering natural
light, strobe lights and with particular patterns or flicker frequencies on
television and video games.
Methods & Results
We present a novel case of photosensitivity captured during
video EEG monitoring showing reproducible photosensitivity with the
ever-popular social phenomenon; the “selfie.” The patient had previously
demonstrated photosensitive myoclonus with intermittent photic stimulation on
routine EEG.
Conclusion
This case suggests that taking “selfies” may represent a new
area of caution for those with photosensitive epilepsies.

From the article
The popularity of the self-photograph coined “selfie” has
risen dramatically over the last several years. In recent years, the risks of
taking selfies in precarious situations such as driving or posing with weapons
have become increasingly apparent. However, there may be
additional unique risks for those with photosensitive epilepsy as many camera
phones use a pulsed LED flash to enable red eye reduction prior to taking a
photo in a dark environment. We are not aware of any previous reports of a
photoparoxysmal response demonstrated while taking a “selfie”. Herein, we
describe a patient with previously documented photosensitivity, clinical
myoclonus and photoparoxysmal response to taking a “selfie” with a smartphone…
In addition, we noted time-locked bursts of generalized spike wave with the patient’s use of an
iPhone-5 camera to take “selfies” with flash and red-eye reduction in a dimly-lit
room. This was
only seen with the camera held close to the patient’s face
at arm’s length. The adolescent was not aware of any unusual jerks with these
paroxysmal EEG discharges and no accompanying myoclonus was seen on video
monitoring…
The popularity of the “selfie” photo continues to grow being
used by celebrities, politicians and the general public alike. Though
photosensitivity is fairly uncommon among those with epilepsy, people with
photosensitive epilepsies must be aware of potential triggers. The finding of a
photosensitivity response to a “selfie” raises concern over this seemingly
harmless everyday activity for those with a prominent photosensitive response.
Injuries while taking “selfies” have already been frequently documented in the
media but those with photosensitive epilepsies may need extra caution. There
are reports of deaths and serious injury incurred while taking “selfies” and of
frequent “selfies” taken while driving motor vehicles. If a person with
epilepsy were to have myoclonus induced by the flash of a “selfie” they could
certainly sustain significant injury; particularly if they were already in a
dangerous situation.
There are frequent warning labels for people with epilepsy
pertaining to the use of video games. Many of these are not substantiated by evidence
of a real elevated risk of seizure while playing the particular video
game. Nevertheless, these warning labels are pervasive. However, mobile phones
capable of producing “selfies” with provoking flash frequencies do not
come with any such
warning. We feel that this is an area for further
consideration. Our finding was isolated to one patient discovered incidentally during
continuous video EEG monitoring and should be corroborated in other individuals
with known photosensitivity on EEG before any official warning labels
would be recommended.
