What is EEG test used to diagnose?
EEG results show changes in brain activity that may be useful in diagnosing brain conditions, especially epilepsy and other seizure disorders. An electroencephalogram (EEG) is a test that detects electrical activity in your brain using small, metal discs (electrodes) attached to your scalp.
What problems can an EEG detect?
An electroencephalogram (EEG) is a noninvasive test that records electrical patterns in your brain. The test is used to help diagnose conditions such as seizures, epilepsy, head injuries, dizziness, headaches, brain tumors and sleeping problems. It can also be used to confirm brain death.
What does a normal EEG rule out?
Your neurologist reads the EEG to look for clues in the brain’s activity that may help define the cause or type of seizure. A normal EEG does not rule out the possibility of epilepsy. In fact, since the EEG records only a 30-minute snapshot of the brain’s activity, many EEGs are normal.
Why would a doctor order an EEG?
Why It’s Done Most EEGs are done to diagnose and monitor seizure disorders. EEGs also can identify causes of other problems, such as sleep disorders and changes in behavior. They’re sometimes used to evaluate brain activity after a severe head injury or before a heart transplant or liver transplant.
What happens if EEG is abnormal?
An abnormal EEG means that there is a problem in an area of brain activity. This can offer a clue in diagnosing various neurological conditions. Read 10 Conditions Diagnosed With an EEG to learn more. EEG testing is one part of making a diagnosis.
What are the possible causes for an abnormal EEG?
Abnormal results on an EEG test may be due to:Abnormal bleeding (hemorrhage)An abnormal structure in the brain (such as a brain tumor)Tissue death due to a blockage in blood flow (cerebral infarction)Drug or alcohol abuse.Head injury.Migraines (in some cases)Seizure disorder (such as epilepsy)
Can you have a false abnormal EEG?
(weak) EEG abnormality is a common cause of inappropriate diagnoses of seizures…” The misdiagnosis of epilepsy is common and has very serious consequences. It is in fact a life-changing diagnosis. A major contributor to the misdiagnosis of epi- lepsy is the tendency to over-read normal tracings as abnormal.
Can a EEG show past seizures?
The EEG generally records brain waves between seizures, called interictal brain waves. These waves may or may not show evidence of seizure activity.
Does anxiety show up on EEG?
We see anxiety as one manifestation of diminished self-regulation by the brain. The condition is often quite obvious in the EEG. The condition is highly responsive to brainwave training.
Should I see a neurologist for anxiety?
You may want to see a neurologist if these movement problems interrupt your daily life, though something like a tremor can be a side effect of medication or anxiety. However, if your tremors also affect your daily activities, you may want to see a neurologist.
Can an EEG show mental illness?
Quantitative frequency analysis of EEG data (QEEG) is useful in research and exceptionally as a supplement to diagnosis in clinical settings. To date, no QEEG methods have been accepted as reliable independent markers for psychiatric disorders or treatment response.
Can anxiety attacks look like seizures?
The symptoms of anxiety – particularly panic attacks – can look and feel a lot like the symptoms of some types of epileptic seizure. This means that both conditions can be misdiagnosed. Some people with epilepsy are told they are having panic attacks, when they are actually experiencing seizures.

What can mimic a seizure?

What’s the difference between a panic attack and an anxiety attack?
Panic attacks can occur without a trigger whereas anxiety usually occurs in response to a perceived stressor or threat. Panic attacks are intense and disruptive and sometimes the physical symptoms are worse than the anxiety. Panic attacks often involve a sense of “unreality” and detachment.
What triggers a panic attack?
Factors that may increase the risk of developing panic attacks or panic disorder include: Family history of panic attacks or panic disorder. Major life stress, such as the death or serious illness of a loved one. A traumatic event, such as sexual assault or a serious accident.

How do I know if its a panic attack or heart attack?
Although chest pain is common to both a panic attack and a heart attack, the characteristics of the pain often differ. During a panic attack, chest pain is usually sharp or stabbing and localized to the middle of the chest. Chest pain from a heart attack may resemble pressure or a squeezing sensation.
