What causes silent seizures?

Causes. Seizures result from overactivity in the brain. Absence seizures occur most often in people under age 20, usually in children ages 4 to 12. In some cases, the seizures are triggered by flashing lights or when the person breathes faster and more deeply than usual (hyperventilates).

What happens during a silent seizure?

Absence seizures involve brief, sudden lapses of consciousness. They're more common in children than in adults. Someone having an absence seizure may look like he or she is staring blankly into space for a few seconds. Then, there is a quick return to a normal level of alertness.

How do I stop silent seizures?

Certain 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 happens if absence seizures go untreated?

Usually absence seizures last no longer than 15 seconds, but that loss of consciousness can make paying attention in school and learning more difficult especially when they occur multiple times a day. Children who have absence seizures may miss things throughout the day and even risk getting hurt.

How do you detect a silent seizure?

An EEG is a test most often used to diagnose absence seizures. This test records the brain's electrical activity and spots any abnormalities that could indicate an absence seizure.

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

Can stress cause absence seizures?

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 does a mini seizure feel like?

Absence (or petit mal) seizures: You seem disconnected from others around you and don't respond to them. You may stare blankly into space, and your eyes might roll back in your head. They usually last only a few seconds, and you may not remember having one.

Can silent seizures cause brain damage?

While absence seizures occur in the brain, they don't cause brain damage. Absence seizures won't have any effect on intelligence in most children. Some children may experience learning difficulties because of their lapses in consciousness. Others may think they're daydreaming or not paying attention.

Does lack of sleep cause absence seizures?

Yes, it can. Seizures are very sensitive to sleep patterns. Some people have their first and only seizures after an "all-nighter" at college or after not sleeping well for long periods. If you have epilepsy, lack of "good sleep" makes most people more likely to have seizures.

What is the best medicine for absence seizures?

Management and Treatment

Absence seizures are treated with antiseizure medications. Ethosuximide (Zarontin®) is the preferred medication to treat absence seizures. Other medications that your healthcare provider might try include valproate (Depakene®), lamotrigine (Lamictal®) and topiramate (Topamax®).

How common are absence seizures in adults?

Absence seizures can happen more than 100 times each day. Absence seizures usually do not cause serious health problems. Some people also develop another type of seizure called a tonic-clonic seizure. This is a seizure that causes convulsions.

Can I drive if I have absence seizures?

In most states, you must be seizure-free for anywhere from 6 months to a year before you'll be allowed to drive. To reach that milestone, honestly discuss your seizures with your doctor and work with them to find the right treatment.

How often do absence seizures happen?

They can also happen many times a day, from 10 and up to over 100. They are sometimes divided into 'typical' and 'atypical' absence seizures. A typical absence seizure consists of a sudden loss of awareness.

Can stress cause seizures without epilepsy?

Even in people without epilepsy, stress and anxiety can trigger PNES, which are also known as pseudoseizures. PNES are physiologically different from the neurological seizures found in epilepsy.

How do I know if I had a seizure?

A staring spell. Uncontrollable jerking movements of the arms and legs. Loss of consciousness or awareness. Cognitive or emotional symptoms, such as fear, anxiety or deja vu.

How long can a seizure last before brain damage?

If convulsive status epilepticus lasts for 30 minutes or longer it can cause permanent brain damage or even death.

Can dehydration cause a seizure?

Seizures can result from severe imbalances in electrolytes due to dehydration. Dehydration can reduce the amount of blood in the body, which can put strain on the heart and cause shock.

Can an EEG show past seizure activity?

The likelihood of recording a seizure during a routine EEG is small. The EEG generally records brain waves between seizures, called interictal brain waves. These waves may or may not show evidence of seizure activity.

How do you know if I had a seizure in my sleep?

Can silent seizures cause memory loss?

Symptoms of silent seizures include a momentary loss of responsiveness, a blank stare, or fluttering eyelids. Recently, researchers have found that these seizures affect people with non-genetic Alzheimer's disease and might have something to do with their memory loss.

Can anxiety cause seizures?

However, according to research on the experiences of people with seizures, stress and anxiety can trigger seizures, and current research often underestimates the role they may play. Lack of sleep is a common trigger for seizures, and this can often happen in people who are experiencing overwhelming stress.

Do seizures show up on MRI?

Magnetic resonance spectroscopy uses an MRI machine to analyze the molecular components of tissue in a particular area of the brain. This helps doctors differentiate a seizure from another condition, such as a metabolic disorder, tumor, or stroke.

Do people remember seizures?

In focal aware seizures (FAS), previously called simple partial seizures, the person is conscious (aware and alert) and will usually know that something is happening and will remember the seizure afterwards. Some people find their focal aware seizures hard to put into words.

What do non epileptic seizures look like?

Non- epileptic seizures may appear to be generalized convulsions, similar to grand mal epileptic seizures, characterized by fall- ing and shaking. They also may resemble petit mal epileptic seizures, or complex partial seizures, characterized by tem- porary loss of attention, staring into space or dozing off.

What is a aura seizure?

Some patients have an unusual sensation or feeling, known as an aura, that alerts them to an upcoming seizure before it happens. The aura is actually a simple focal seizure, also known as a partial seizure. These types of seizures only affect a small part of the brain and only occur in one side of the brain.
