A silent seizure, known medically as an absence seizure (formerly "petit mal"), looks like a brief, sudden, and temporary loss of consciousness, often resembling a "staring spell" or daydreaming. The person typically stops all activity, stares blankly, and becomes unresponsive for 5–20 seconds. They do not fall or shake, making them difficult to detect.

• Small movements of both hands.

What is mistaken for absence seizures?

Staring and daydreaming are sometimes confused for an absence seizure. A child may appear to be staring off into space and at first doesn't respond to his name. Probably that child is simply concentrating or thinking about another place or time. An absence seizure is different.

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).

Example of Absence Seizure

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.

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.

What is micro seizure?

Electrographic seizure-like discharges isolated to single microelectrodes that demonstrated temporal and spectral evolution commonly associated with clinical macroelectrode seizures were labelled 'microseizures'.

What happens if absence seizures go untreated?

For some children, untreated seizures can get worse over time and may affect learning, development, or behavior. Most children can get complete seizure control by taking the medicine. About 60% of children outgrow absence seizures in their teens, especially if medicine has worked well to control their seizures.

What are the early warning signs of seizures?

Seizure symptoms may include:

• Short-lived confusion.
• A staring spell.
• Jerking movements of the arms and legs that can't be stopped.
• Loss of consciousness or awareness.
• Changes in thinking or emotions. These may include fear, anxiety or a feeling of already having lived the moment, called deja vu.

Can silent seizures cause brain damage?

Absence seizures themselves, which nearly always are very brief, do not injure the brain. Once in a while, absence seizures can continue for hours to days, a condition known as absence status epilepticus, but the risk of injury from even very prolonged bouts is extremely remote.

How common are silent seizures?

How common are absence seizures? Absence seizures affect an estimated 6 to 8 out of every 100,000 children younger than 15 years old each year. Absence seizures in adults are less common.

How to handle silent seizures?

What does a pots seizure look like?

POTS itself does not usually cause epileptic seizures. However, fainting episodes related to POTS can sometimes include seizure-like convulsions or jerky movements. As shown in case reports, patients with POTS may be misdiagnosed with epilepsy even though their EEG and neurological workup remain normal.

What does the ER do for seizures?

The ER stops active seizures with fast-acting IV benzodiazepines (like lorazepam, diazepam) and provides oxygen, stabilizes the patient, and investigates the cause with tests like EEG and brain scans (CT/MRI) to rule out emergencies like stroke or infection. Their primary goals are to halt prolonged seizures quickly to prevent brain damage, ensure breathing stability, and identify underlying triggers like infection, low blood sugar, or trauma, often leading to neurology follow-up or hospital admission.
 

What does pre-seizure feel like?

Aura phase: Right before the first symptoms of a seizure start, you may notice vision changes, a headache, dizziness, nausea, anxiety or fear, and changes to your senses (like taste, sound, smell and feeling). Ictal phase: This is when a seizure happens. You'll experience seizure symptoms.

What side do you lay on when having a seizure?
