Flickering or Flashing Light
If you have
photosensitive epilepsy, certain types of flickering or flashing light may incite a seizure. The trigger could be exposure to television screens due to the flicker or rolling images, computer monitors, certain video games or TV broadcasts containing rapid flashes, even alternating patterns of different colors, in addition to intense strobe lights.
And surprisingly, seizures may be triggered by natural light, such as sunlight, especially when shimmering off water, even sun flickering through trees or through the slats of Venetian blinds.
Stress
Stress can trigger hyperventilation which can provoke seizures, especially absence seizures.
It can increase cortisol, known as “the stress hormone” because cortisol is secreted in higher levels during the body’s “fight or flight” response to stress. And it’s responsible for several stress-related changes in the body which also may influence seizure activity.
Negative emotions related to stress, such as anger, worry or fright, may also cause seizures. This happens because the
limbic system, the portion of the brain that regulates emotion, is one of the most common places for seizures to begin.
Lack of Sleep
Inadequate or fragmented sleep can set off seizures in lots of people. In one study, the lowest risk for seizures was during REM sleep (when dreams occur). The highest risk was during light non-REM stages of sleep.
Hormones
For many women, certain hormones seem to trigger seizures at particular times in their menstrual cycle. It can be during ovulation, menstruation, pregnancy or menopause. This is known as
“catamenial epilepsy.” If you’re going through menopause, you may find that the hormonal changes at this time make you more likely to have seizures, (although for some women, seizures will not be affected or become less frequent).
Food Allergies
Both food sensitivities and allergies can definitely trigger seizures. Especially foods that are rich in
glutamate and aspartame – two very excitatory amino acids. Food allergies may also trigger seizures in children who also have migraine headaches, hyperactive behavior and abdominal pains.
Prescription Drugs
Some prescription medications — especially penicillin, anti-depressants and anti-anxiety drugs — can prevent your medication from working.
It could be caused by the way your system responds to a certain a drug, a combination of drugs, reaction or withdrawal. Make sure all your doctors know everything you take.
Over-the-Counter-Drugs
Certain over-the-counter medications (Advil and Tylenol are fine but never take aspirin!) can make you more likely to have a seizure, if you have epilepsy or a history of seizures. For example,
anti-depressants and antihistamines are possible seizure triggers. Also certain supplements — like evening primrose oil — can also be a trigger.
Alcohol
There are two questions that have to be considered when the question of alcohol use and epilepsy comes up. One is
the effect that alcohol could have on the medicines used to control seizures. Alcohol can be dangerous when mixed with sedative drugs and can cause coma, or even death. The other question is whether the alcohol itself will cause seizures.
Large amounts of alcohol are thought to raise the risk of seizures and may even cause them. When you drink alcohol, it may temporarily reduce seizures for a few hours, but then increases the chances of a seizure as the alcohol leaves your body.
Cigarette Smoking
Nicotine is both a stimulant and a depressant to the central nervous system. The nicotine in cigarettes acts on receptors for the excitatory neurotransmitter acetylcholine in the brain, which increases neuronal firing.
Caffeine
Much like nicotine, caffeine stimulates the nervous system. Adrenaline is released and the liver begins to emit stored blood sugar. Insulin is then released, and blood sugar drops below normal—a common seizure trigger. And
caffeine can be a “stealth” drug, too. It can be found as an ingredient in medications, including some antihistamines and decongestants.
Musicogenic Epilepsy
This is a form of reflexive epilepsy in which a seizure is triggered by music or specific frequencies. Sensitivity to music varies from person to person. Some people are sensitive to a particular tone from a voice or instrument. Others are sensitive to a particular musical style or rhythm. Still others are sensitive to a range of noises.
Individual Triggers
A common trigger is too much heat, internal from extremely excessive exercise or external from an overheated house or apartment. Other triggers include the smell of glue and the color yellow! Many people have their own specific triggers, while others don’t. It’s a combination of possibilities: personal chemistry, biology and genetics.
