What does an abnormal EEG mean in a child?

What does an abnormal EEG mean in a child?

If a child has an abnormal EEG it does not indicate they had a seizure or ever will have a seizure. Likewise, if a child has a normal EEG, it does not mean they will never have a seizure. An EEG is just a snapshot of the electrical activity in the brain at that moment in time.

What does a mildly abnormal EEG mean?

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.

Can you have an abnormal EEG without having epilepsy?

This means that sometimes the EEG is described as ‘abnormal’ (that is ‘not normal’ brain activity) but does not ‘prove’ that the person has epilepsy. To complicate this further, some people have ‘abnormal’ EEGs but do not have epilepsy.

Is abnormal EEG bad?

Yes, EEG can be bad for you. The consequences of being misdiagnosed with epilepsy are obvious and serious [9]. When the diagnosis is based largely on an abnormal EEG, no amount of subsequent normal EEGs will ‘cancel’ the previous abnormal one, and the wrong diagnosis is very difficult to undo.

Can an EEG miss a brain tumor?

The low specificity and sensitivity of EEG (even in patients with clinical seizures as primary symptom of a brain tumor) underline that EEG does not contribute to diagnosis and a normal EEG might even delay correct diagnosis.

What does brain damage look like on an EEG?

When an injury is incurred by the brain there are a few varieties of findings seen in the EEG, ranging from spectral changes associated with either white or gray matter damage, to the changes in “connectivity”, seen as changes in coherence or correlation measured across the cortex, or between more distant functionally …

Can EEG detect anxiety?

Increased communication between the amygdala and hippocampus appear to correlate with symptoms of depression and anxiety, in findings that may have treatment implications, new research suggests.

Can you see brain damage on an EEG?

Electroencephalography (EEG) was the first clinical neurodiagnostic assessment that revealed abnormal brain function following traumatic brain injury. To detect brain injury, EEG may be more sensitive than clinical neurological examination.
