How are seizures diagnosed?
An electroencephalogram (EEG).
In this test, doctors attach electrodes to your scalp with a paste-like substance. The electrodes record the electrical activity of your brain, which shows up as wavy lines on an EEG recording. The EEG may reveal a pattern that tells doctors whether a seizure is likely to occur again.
What is the difference between seizures and epilepsy?
A seizure is a single occurrence, whereas epilepsy is a neurological condition characterized by two or more unprovoked seizures.
What do seizures do to the brain?
A seizure is a burst of uncontrolled electrical activity between brain cells (also called neurons or nerve cells) that causes temporary abnormalities in muscle tone or movements (stiffness, twitching or limpness), behaviors, sensations or states of awareness. Seizures are not all alike.
What does a seizure feel like in your head?
You're not likely to lose consciousness, but you might feel sweaty or nauseated. Complex focal seizures: These usually happen in the part of your brain that controls emotion and memory.

How are seizures treated?
Treatments include: medicines called anti-epileptic drugs (AEDs) surgery to remove a small part of the brain that's causing the seizures. a procedure to put a small electrical device inside the body that can help control seizures.
What is the difference between a stroke and a seizure?
A stroke happens when blood flow to the brain is interrupted. A seizure occurs when the brain experiences a surge of electrical activity. For easy reference, think of it this way.

- Oxcarbazepine (Oxtellar, Trileptal)
- Lamotrigine (Lamictal)
- Gabapentin (Gralise, Neurontin)
- Topiramate (Topamax)
- Phenobarbital.
Does an EEG show past seizures?
An EEG can usually show if you are having a seizure at the time of the test, but it can't show what happens to your brain at any other time. So even though your test results might not show any unusual activity it does not rule out having epilepsy.
Can blood work Show seizures?
