A silent seizure, known medically as an absence seizure or petit mal seizure, is a brief episode (usually 10–20 seconds) of altered consciousness where a person suddenly stops activity and stares blankly into space. Common in children aged 4–14, these seizures often go unnoticed as they involve no falling, jerking, or convulsing, appearing instead like intense daydreaming.

What does a silent seizure look like?

Typical Absence Seizures

The person suddenly stops all activity without any warning. It may look like he or she is staring off into space or just has a blank look. The eyes may turn upwards and eyelids flutter. The seizures usually last less than 10-20 seconds.

Are silent seizures harmful?

Are absence seizures dangerous? 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.

How long does a silent seizure last?

A simple absence seizure causes a vacant stare, which may be mistaken for a brief lapse in attention. 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.

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.

Absence seizure, Causes, Signs and Symptoms, Diagnosis and Treatment.

Does my brain get permanently damaged after a seizure?

Isolated brief seizures probably do not kill neurons; however, severe and repetitive seizures (i.e., status epilepticus) certainly do. Because status epilepticus both kills neurons and also leads to chronic epilepsy, neuronal death has been proposed to be an integral part of acquired epileptogenesis.

What's the worst type of seizure you can have?

The "worst" type of seizure is subjective, but Status Epilepticus, a prolonged seizure (over 5 minutes) or repeated seizures without recovery, is a life-threatening emergency that can cause brain damage or death, making it arguably the most dangerous. While scary, generalized tonic-clonic seizures (formerly grand mal) are the most commonly feared due to their dramatic convulsions, but the real danger lies in their duration (Status Epilepticus) or if they evolve from focal seizures.

Can you drive if you have silent seizures?

To get a driver's license in most U.S. states, a person with epilepsy must be free of seizures that affect consciousness for a certain period of time. The seizure-free period varies from state to state. More recently, shorter intervals of seizure freedom are being required, for example 3 to 6 months.

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 can be 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.

What looks like a seizure but is not a seizure?

Some people experience symptoms similar to those of an epileptic seizure but without any unusual electrical activity in the brain. When this happens it is known as a non-epileptic seizure (NES). NES is most often caused by mental stress or a physical condition.

What is the treatment for silent seizures?

The treatment of choice for CAE with absence seizures only is ethosuximide. Valproic acid and lamotrigine are also effective treatments for many patients, but when compared to ethosuximide, valproic acid has more adverse effects and lamotrigine is less effective.

What is the rule of 3 for seizures?

The "Rule of 3" for seizures refers to two different concepts: a medical guideline for defining seizure freedom (wait 3 times the longest prior seizure interval) and first-aid steps (Stay, Safe, Side). Medically, the "Rule of Three-To-Six" suggests waiting three times the typical seizure interval to confirm seizure freedom after an intervention, but potentially longer (up to six times) if seizure risk is high, while clinically, the 3 S's (Stay, Safe, Side) guide first aid: Stay with the person, ensure they are Safe, and turn them on their Side for breathing.
 

What type of seizure has the highest risk of death?

The greatest risk factor for SUDEP is having tonic clonic seizures (grand mal). People with night time seizures may also be at higher risk. Missing medications or not taking seizure medicines as prescribed, because it can lead to more seizures, may also put people at higher risk for SUDEP.

Do seizures rewire your brain?

Research performed over several decades suggests that seizure-induced brain injury is highly dependent upon developmental age, with the juvenile and adult brain being more susceptible to damage and rewiring after seizures than the brain of the newborn.

Do seizures reduce life expectancy?

Epilepsy can shorten life, but most of the time it does not. Be aware of risks and take sensible precautions, but do not let the risks put you into a state of constant worry. Consult with your doctor for specific information about your risk factors for injury due to seizures.

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.
 

Are eyes open during seizures?

Ninety percent of patients had closed eyes, an uncommon feature during an epileptic generalized seizure; 10% of patients had open eyes. These patients frequently had a history of epileptic seizures.

What should you never do during a seizure?

What to avoid

• 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.
• Don't give mouth-to-mouth breaths during the seizure. ...
• Don't offer water or food until they are fully alert.
