Disney/Pixar may now include a warning for viewers that some scenes in their latest hit, Incredibles 2, may induce seizures at the request of the National Epilepsy Foundation. Some viewers found the strobe and flashing light scenes to be potential seizure triggers.

Veronica Lewis tweeted the following:

HEALTH ALERT I haven’t seen this mentioned in a lot of places, but the new Incredibles 2 movie (#incredibles2) is filled with tons of strobe/flashing lights that can cause issues for people with epilepsy, migraines, and chronic illness.

 

What is a seizure?

 

A seizure occurs when there is abnormal electrical activity in the brain.  If the electricity doesn’t conduct properly, brain function gets disrupted. This could lead to convulsions  (involuntary jerking movements), loss of muscle tone, changes in senses such as vision, hearing and smell, loss of bladder control, loss of consciousness and sometimes stroke, brain damage and death.

What is Epilepsy?

 

Epilepsy is a neurological disorder in which a person has recurrent, unprovoked seizures.

Photosensitive epilepsy, in which visual triggers can induce a seizure, occurs in 1 in 4000 of the population.

Can Movies Cause Seizures?

 

In December of 1997, a Pokemon cartoon aired in Japan resulting in over 700 children to the hospital with ailments ranging from dizziness to epilepsy.  It was determined that the rapidly strobing flashes of red and blue lights induced this “Pokemon Shock.”

A study from Prasad et al in 2012 found no increase risk of seizures with 3D movies than conventional television. They explain why seizures are induced here:

The mechanism in which TV and cinema movies trigger seizures in patients with photosensitive epilepsy is related to several factors including the light intensity, the environment and the frequency of picture frames per second. Normal 2D movies have a frame rate of 24 per second, which may pose a risk for patients with photosensitive epilepsy, but the light intensity in the cinema is very low and there are relatively a few reports of seizures precipitated in cinemas. In contrast, 3D movies project images at 48 frames per second aimed, by the use of colored or polarizing filters, at different eyes and resulting in 24 frames per second per eye. The polarizing effect of 3D films may reduce the light output by around fifty percent leading to a reduced risk to trigger a seizure to people with photosensitive epilepsy. Therefore, the risk of 3D movies to trigger a seizure is around fifty percent less than with conventional 2D movies. However if provocative material such as flashing light is presented the risk can be as high as that for normal 2D movies.

Although there is “insufficient evidence” to connect 3D movies to epilepsy, researchers agree with the need for more study.

Which makes us rely on anecdotal, or testimonial evidence such as the tweet from Veronica Lewis.

“Risky Movies”

 

The following have been suggested on moviehealthcommunity.tumblr.com to have strobe effects or flashing lights that may affect one’s photosensitivity risk of inducing a seizure:

 

  • Ocean’s 8 – fast-moving trains
  • Incredibles 2 - villain weapon
  • Solo, A Star Wars Story – laser fire and sparking electrical equipment
  • Speed Racer – bright headlines, racing cars
  • Deadpool 2 – gunfire, high-speed chase scenes
  • Hostiles -flashes from the gunfire
  • 300 – lightning scenes
  • Avengers, Infinity War – fight scenes, shaking cameras, laser based weapons
  • Iron Man series – strobe and flashing lights
  • Incredible Hulk, 2008 – strobe lights
  • Ready Player One – high-speed chase, shaky camera, flashing lights
  • Tomb Raider, 2018 – strobe lights, shaky cameras
  • A Wrinkle in Time – lightning storm
  • I, Tonya – fast speeds, quick camera shots
  • The Cloverfield Paradox – strobe lights

Although one of my favorite franchises, some of my listeners found the Transformer movies to have similar issues with high speed movements and strobe lights.

Many more movies are listed but the common thread are those with high action, high-speed, strobe lighting, storms, horror, and fast-moving race or fall scenes.

The CDC reports 3.4 million Americans suffer from epilepsy based on their 2015 data.  This number rose from 2.3 million in 2010.  470,000 of these cases are children.

 

According to their website, the CDC reports 1.2% of the population suffers from “active epilepsy.”  Active epilepsy is defined in adults as those having one or more seizures in the past year and requiring medication daily to control them. In children it means they currently have a seizure disorder.

 

The exact explanation for the rise in cases is unclear, however population growth and improved testing has been cited.

Epilepsy and seizures can be caused by a multitude of factors including genetics, brain trauma, tumors, infection, damage during birth, and stroke.

Can cell phones cause seizures?

 

Data has been limited linking seizure activity to cell phone use. However, some studies have found a modest link.

 

In 2016, Kouchaki et al tested mobile phone radiation in mice and concluded “continued and prolonged contact with the mobile phone radiation might increase the risk of seizure attacks and should be limited.”

 

Also in 2016, a study published in Epilepsy and Behavior by Tatum et al found texting to induce a “new type of brain rhythm.”

 

In 2013, Cinar et al examined the effects of electromagnetic waves (EMWs) on humans and suggested the following, “acute exposure to EMW may facilitate epileptic seizures, which may be independent of EMW exposure time. This information might be important for patients with epilepsy. Further studies are needed.”

 

In 2006, Ferreri et al found mobile phone “emissions” to increase human brain excitability, implying this could affect those with epilepsy.

 

More research therefore needs to be done investigating why epilepsy cases are on the rise and if cell phone radiation plays any role.
