A BEGINNER’S GUIDE TO UNDERSTANDING THE MAIN TYPES OF SEIZURES
Seizures can be scary if you don’t know what’s happening Cranial Neurosurgery. Maybe you’ve seen someone have one, or you’re trying to understand your own diagnosis. Either way, myths about seizures make things worse. They lead to bad decisions—like delaying help, using dangerous first aid, or feeling unnecessary shame. This guide breaks down the main types of seizures and busts the biggest myths that trip people up.
WHAT IS A SEIZURE, REALLY?
A seizure is a sudden, uncontrolled electrical disturbance in the brain. It can cause changes in behavior, movements, feelings, or consciousness. Not all seizures look the same. Some last seconds; others last minutes. Some cause shaking; others make you stare blankly. The type depends on where the electrical storm starts in the brain and how far it spreads.
MYTH #1: ALL SEIZURES INVOLVE CONVULSIONS
People picture seizures as full-body shaking, foaming at the mouth, and falling to the ground. That’s one type, but not the only one. Many seizures don’t involve convulsions at all.
Why it’s wrong: The brain has different areas that control different functions. If the electrical disturbance stays in a small area, you might not see big movements. For example, a focal aware seizure can cause a sudden strange smell, a wave of fear, or a twitch in one finger—no convulsions, no loss of consciousness.
The truth: Seizures come in two main categories: focal (starting in one area) and generalized (affecting both sides of the brain at once). Only some generalized seizures cause convulsions. Others, like absence seizures, make you blank out for a few seconds. Don’t assume someone isn’t having a seizure just because they’re not shaking.
MYTH #2: YOU SHOULD PUT SOMETHING IN A PERSON’S MOUTH DURING A SEIZURE
You’ve probably heard this: “Put a spoon or wallet in their mouth so they don’t swallow their tongue.” It’s one of the most dangerous myths out there.
Why it’s wrong: You cannot swallow your tongue during a seizure. The tongue is anchored to the bottom of the mouth. Trying to force something in can break teeth, cut gums, or block the airway. It also puts your fingers at risk—people having convulsive seizures can bite down hard.
The truth: Turn the person on their side to keep their airway clear. Loosen tight clothing around the neck. Time the seizure. If it lasts longer than 5 minutes or they don’t wake up afterward, call emergency services. Never put anything in their mouth.
MYTH #3: SEIZURES ARE ALWAYS A SIGN OF EPILEPSY
Many people think seizures and epilepsy are the same thing. They’re not.
Why it’s wrong: Epilepsy is a condition where someone has recurrent, unprovoked seizures. But seizures can happen to anyone, even without epilepsy. Triggers include low blood sugar, high fever (especially in kids), alcohol withdrawal, drug use, or a head injury. A single seizure doesn’t mean you have epilepsy.
The truth: If someone has a seizure for the first time, they need medical evaluation. Doctors will look for the cause. If it’s a one-time event, they may not diagnose epilepsy. Don’t jump to conclusions—get the facts first.
MYTH #4: YOU SHOULD RESTRAIN SOMEONE DURING A SEIZURE
People panic when they see someone shaking uncontrollably. They try to hold them down to “stop the seizure.” This is a bad idea.
Why it’s wrong: Seizures are caused by electrical activity in the brain. You can’t stop them by restraining the body. Holding someone down can cause injuries—dislocated shoulders, bruises, or even fractures. It also increases their distress.
The truth: Clear the area of hard or sharp objects. Cushion their head with something soft. Let the seizure run its course. Only intervene if they’re in immediate danger, like near a staircase or hot stove. Otherwise, stay calm and keep them safe.
MYTH #5: SEIZURES ALWAYS CAUSE BRAIN DAMAGE
This myth makes people terrified of seizures. They assume every seizure leaves permanent damage. That’s not true.
Why it’s wrong: Most seizures are short and don’t cause long-term harm. The brain is resilient. Brief seizures, like absence or focal aware seizures, don’t typically damage brain cells. Even convulsive seizures that last a few minutes usually don’t cause lasting problems.
The truth: Prolonged seizures (lasting more than 5 minutes) or repeated seizures without recovery in between (status epilepticus) can be dangerous. These require emergency treatment to prevent brain injury. But most seizures don’t fall into this category. Don’t assume the worst—focus on getting the right care.
THE MAIN TYPES OF SEIZURES EXPLAINED
Now that we’ve cleared up the myths, let’s break down the main types of seizures. Knowing the differences helps you recognize them and respond correctly.
FOCAL SEIZURES
Focal seizures start in one area of the brain. They’re sometimes called partial seizures. There are two types:
Focal aware seizures: The person stays conscious. They might experience strange sensations, emotions, or movements. For example, a sudden taste of metal, a feeling of déjà vu, or jerking in one arm. These seizures can be subtle and easy to miss.
Focal impaired awareness seizures: The person loses awareness or becomes confused. They might stare blankly, smack their lips, or wander around. Afterward, they won’t remember what happened. These can be mistaken for daydreaming or drunkenness.
GENERALIZED SEIZURES
Generalized seizures affect both sides of the brain at once. There are several types:
Absence seizures: These are brief and often go unnoticed. The person stares into space for a few seconds, then snaps back. They might blink rapidly or smack their lips. Kids often get these, and they’re sometimes mistaken for not paying attention.
Tonic-clonic seizures: These are the ones most people picture. The body stiffens (tonic phase), then jerks (clonic phase). The person loses consciousness and may fall. They might bite their tongue or lose bladder control. Afterward, they’ll feel confused or sleepy.
Atonic seizures: The muscles suddenly go limp. The person might drop their head or collapse. These are sometimes called “drop attacks.” They’re dangerous because the person can hit their head.
Myoclonic seizures: These cause sudden, brief jerks in the arms or legs. They’re like a quick electric shock. They can happen in clusters, especially when waking up.
Tonic seizures: The muscles stiffen, but there’s no jerking. The person might fall backward if standing.
Clonic seizures: These involve repeated jerking movements. They’re less common than tonic-clonic seizures.
UNKNOWN ONSET SEIZURES
Sometimes, it’s unclear where the seizure started. These are called unknown onset seizures. They might be classified later as focal or generalized once more information is available.
