Photosensitive Seizures
A very small percentage of people may
experience a seizure when exposed to
certain visual images, including flashing
lights or patterns that may appear in
video games. Even people who have no
history of seizures or epilepsy may have
an undiagnosed condition that can cause
these "photosensitive epileptic seizures"
while watching video games.
These seizures may have a variety of
symptoms, including lightheadedness,
altered vision, eye or face twitching,
jerking or shaking of arms or legs,
disorientation, confusion, or momentary
loss of awareness. Seizures may also
cause loss of consciousness or
convulsions that can lead to injury from
falling down or striking nearby objects.
Immediately stop playing and consult a
doctor if you experience any of these
symptoms. Parents should watch for or
ask their children about the above
symptoms—children and teenagers are
more likely than adults to experience
these seizures. The risk of photosensitive
epileptic seizures may be reduced by
taking the following precautions:
• Sit farther from the TV screen.
• Use a smaller TV screen.
• Play in a well-lit room.
• Do not play when you are drowsy or
fatigued.
If you or any of your relatives have a
history of seizures or epilepsy, consult a
doctor before playing.
Musculoskeletal Disorders
Use of game controllers, keyboards, mice,
or other electronic input devices may be
linked to serious injuries or disorders.
When playing video games, as with many
activities, you may experience occasional
discomfort in your hands, arms, shoulders,
neck, or other parts of your body.
However, if you experience symptoms
12
such as persistent or recurring discomfort,
pain, throbbing, aching, tingling,
numbness, burning sensation, or stiffness,
DO NOT IGNORE THESE WARNING SIGNS.
PROMPTLY SEE A QUALIFIED HEALTH
PROFESSIONAL, even if symptoms occur
when you are not playing a video game.
Symptoms such as these can be
associated with painful and sometimes
permanently disabling injuries or
disorders of the nerves, muscles, tendons,
blood vessels, and other parts of the
body. These musculoskeletal disorders
(MSDs) include carpal tunnel syndrome,
tendonitis, tenosynovitis, vibration
syndromes, and other conditions.
While researchers are not yet able to
answer many questions about MSDs,
there is general agreement that many
factors may be linked to their occurrence,
including medical and physical conditions,
stress and how one copes with it, overall
health, and how a person positions and
uses their body during work and other
activities (including playing a video game).
Some studies suggest that the amount of
time a person performs an activity may
also be a factor.
Some guidelines that may help you work
and play more comfortably and possibly
reduce your risk of experiencing an MSD
can be found in the Healthy Gaming Guide
at www.xbox.com. These guidelines
address topics such as:
• Positioning yourself to use
comfortable, not awkward, postures.
• Keeping your hands, fingers, and other
body parts relaxed.
• Taking breaks.
• Developing a healthy lifestyle.
If you have questions about how your own
lifestyle, activities, or medical or physical
condition may be related to MSDs, see a
qualified health professional.
