A "micro-seizure" isn't a formal medical term but generally refers to very brief, localized brain activity, often seen as focal aware seizures (auras) or myoclonic jerks, which are small, isolated electrical disturbances that might be missed but can signal underlying issues, sometimes evolving into larger seizures, with key examples being brief staring spells (absence seizures) or sudden twitches.

What triggers myoclonic seizures?

Myoclonic seizures are sudden, brief jerks of muscles that can be triggered by factors like sleep deprivation, stress, flashing lights, or certain medications.

How long do micro seizures last?

The seizure lasts about 10 seconds, though it may last as long as 30 seconds. There's no confusion, headache or drowsiness after the seizure. Symptoms of absence seizures include: A sudden stop in activity without falling.

How do you treat micro seizures?

How are they treated? Certain anti-seizure medicines can help prevent absence seizures. Usually these are recommended for most children. The medicines most commonly used for absence seizures include ethosuximide (Zarontin), lamotrigine (Lamictal), valproic acid (Depakene), or divalproex sodium (Depakote).

What is the 5 minute rule for seizures?

The "5-minute rule" for seizures means that if a seizure lasts longer than 5 minutes, it's a medical emergency requiring immediate 911 (or local emergency number) assistance, as prolonged seizures (status epilepticus) can cause brain damage. Always time the seizure, call for help if it exceeds 5 minutes, if another seizure starts without full recovery, if the person has breathing issues, is injured, pregnant, diabetic, or if it's their first seizure, as these also warrant emergency care.

Example of Absence Seizure

How serious are mini seizures?

Absence seizures aren't usually dangerous. This is because they're usually short and rarely cause convulsions. For example, if you're standing up when an absence seizure happens, you likely won't fall. Instead, you'll stop in place for a few seconds.

What are the early signs of myoclonic seizures?

Symptoms of these seizures include:

• Quick, uncontrolled muscle jerks.
• Jerky or rhythmic movements.
• Unusual clumsiness.

How do doctors treat myoclonic seizures?

The most common anticonvulsants used for myoclonus are levetiracetam (Keppra, Elepsia XR, Spritam), valproic acid, zonisamide (Zonegran, Zonisade) and primidone (Mysoline). Piracetam is another anticonvulsant that's been found to be effective, but it's not available in the United States.

Can you talk during a mini seizure?

Focal onset aware seizures do not cause a loss of awareness. A person can sometimes talk during these types of seizures and remember them after they happen. These types of seizures used to be called “simple partial seizures.”

What age do absence seizures usually start?

Absence seizures are generally seen in children aged 5 to 15 years and occur in multiple genetic generalized epilepsies, including childhood absence epilepsy (CAE), juvenile absence epilepsy (JAE), and juvenile myoclonic epilepsy (JME).

What causes seizures in adults with no history?

Causes of first-time seizures in adults include stroke, traumatic brain injury (TBI), high fever, and hypoglycemia (low blood sugar).

What side do you lay on when having a seizure?

You don't want the person experiencing a seizure to fall or hit their head on a counter or a piece of furniture. The ideal situation is to get them to the floor and clear an area around them. Lay on the left. Once you have them on the floor, try to position them on their left side so if they vomit, they don't choke.

What are the three first aid words for seizures?

The Epilepsy Foundation's seizure first aid instructions come down to three S's – Stay, Safe and Side.

What can trigger a small seizure?

Some common seizure triggers include:

• missed medication.
• sleep deprivation – being overtired, not getting enough sleep or not sleeping well.
• stress.
• infection or illness.
• hormonal changes (puberty, menstruation, menopause)
• dehydration.
• low blood sugar.
• alcohol or illicit drug use.

What does a stress seizure look like?

It may look like you're having symptoms similar to tonic-clonic seizures, with full-body shaking that's common in epilepsy. Or you may have twitching or jerking in your limbs. Events may also present as absence seizures (a brief lapse in awareness) or drop attacks.

Should I go to the ER after a seizure?

Yes, you should go to the ER after a seizure if it's your first seizure, lasts over five minutes, involves breathing trouble, causes injury, or if the person is pregnant, diabetic, or remains unconscious/confused afterward, as these are signs of a medical emergency needing urgent evaluation to find the cause and rule out serious issues. For typical seizures that end quickly without complications, follow up with a doctor soon, but the first-time event always warrants ER attention to diagnose the root cause. 

Do seizures cause brain damage?

Although scientists and clinicians have long known that prolonged seizures, a condition referred to as "status epilepticus," kill brain cells, surprisingly little scientific evidence exists to support the notion that individual seizures do damage.

What should you never do during a seizure?

• Don't hold the person down or stop their movements. This could injure you or them.
• Don't put anything in their mouth. This can hurt their teeth or jaw.
