Will absence seizures show up on EEG?

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.

Can absence 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 the lapses in consciousness. Others may think they're daydreaming or not paying attention.

What does an absence seizure look like on an EEG?

In the case of childhood absence seizures, EEG shows bilaterally synchronous and symmetrical 3-Hertz spike-and-wave discharges that start and end abruptly. These discharges can sometimes have maximum frontal amplitude or begin with unilateral focal spikes[2].

What else can look like a seizure?

Movement disorders — Tics, tremors, and other involuntary movements can look like a myoclonic seizure or focal seizure, but they may be caused by things like Tourette's syndrome, Parkinson's disorder, Huntington's disease, and other disorders that affect the brain.

What are seizure mimics?

As assigning a diagnosis a seizure or seizure disorder is not without significant health and quality of life implications (employment repercussions, driving restrictions, etc.1-5), emergency physicians must be aware of conditions that may mimic seizure activity: syncope, psychogenic non-epileptic seizures, metabolic ...

Can petit mal seizures become grand mal?

At that time, a series of petit mal absences and eventually a smooth transition from petit mal to grand mal could be recorded. Uncommon frequency characteristics (especially some interspersed spiking at a rate of 9-15/sec) were found at the onset of the ictal spike-wave activity during the petit mal absences.

How is an EEG used to detect absence seizures?

  • The EEG checks the electrical activity in the brain for patterns usually seen in absence seizures. During the EEG, you may be asked to breath fast or close your eyes while lights are flashed fast. These things may make it easier to see absence seizure patterns on an EEG.

Where to get an ambulatory EEG for epilepsy?

  • The testing can either confirm the diagnosis of epilepsy or find that epilepsy waves are not causing the seizures. Ambulatory EEG monitoring is generally done at a specialized epilepsy center. What's the test like?

What should you do if your EEG is normal?

  • The normal EEG does not mean that the neurologist was wrong in saying that you had a seizure. Keep taking the seizure medicine that was prescribed. If you have a normal EEG and stay free of seizures for two years or more, the neurologist may suggest that you can stop taking it!

When to see an epilepsy specialist for absence seizures?

  • If the diagnosis is not clear or your child continues to have problems, see an epilepsy specialist (called an epileptologist). Kids who have absence seizures aren’t usually in danger during a seizure. However, absence seizures may cause your child to
