The EEG report is structured to include
demographics of the patient studied and reason for the EEG
; specifics of the EEG techniques used; a description of the patterns, frequencies, voltages, and progression of the EEG pattern that were recorded; and finally a clinical impression of the EEG significance.
What is an example of an EEG?
For example, EEG
may be used to monitor the depth of anesthesia during surgical procedures
; given its great sensitivity in showing sudden changes in neural functioning even as they first occur, it has proven quite helpful in this setting in monitoring for potential complications such as ischemia or infarction.
What is normal EEG report?
Most waves of 8 Hz and higher frequencies
are normal findings in the EEG of an awake adult. Waves with a frequency of 7 Hz or less often are classified as abnormal in awake adults, although they normally can be seen in children or in adults who are asleep.
What does a seizure look like in an EEG?
Certain other patterns indicate a tendency toward seizures. Your doctor may refer to these waves as “epileptiform
How would you describe an EEG?
An EEG is
a test that detects abnormalities in your brain waves, or in the electrical activity of your brain
. During the procedure, electrodes consisting of small metal discs with thin wires are pasted onto your scalp. The electrodes detect tiny electrical charges that result from the activity of your brain cells.
What happens if EEG is abnormal?
Abnormal EEG results can show up in two ways. First,
normal brain activity may be suddenly interrupted and changed
. This happens in epileptic seizures. In partial seizures, only part of the brain shows the sudden interruption.
What are the 3 types of seizures?
- absence seizures (formerly known as petit mal)
- tonic-clonic or convulsive seizures (formerly known as grand mal)
- atonic seizures (also known as drop attacks)
- clonic seizures.
- tonic seizures.
- myoclonic seizures.
Can an EEG detect anxiety?
EEG has also been used in the diagnosis of
mental disorders
, such as anxiety [28–30], psychosis [31–34], and depression [35–38].
Why would a neurologist order an EEG?
An EEG can
determine changes in brain activity
that might be useful in diagnosing brain disorders, especially epilepsy or another seizure disorder. An EEG might also be helpful for diagnosing or treating the following disorders: Brain tumor. Brain damage from head injury.
Can EEG read thoughts?
“This measurement technique, known as electroencephalography or EEG, can provide information about brain activity that
could, in principle, be used to read minds
,” said Jeffrey Mark Siskind, professor of electrical and computer engineering in Purdue’s College of Engineering.
What are warning signs of a seizure?
- Staring.
- Jerking movements of the arms and legs.
- Stiffening of the body.
- Loss of consciousness.
- Breathing problems or stopping breathing.
- Loss of bowel or bladder control.
- Falling suddenly for no apparent reason, especially when associated with loss of consciousness.
Can a 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.
What are the possible causes for an abnormal EEG?
- 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)
What Disorders Can an EEG detect?
- Sleep disorders (such as narcolepsy)
- Head injuries.
- Brain infection.
- Brain haemorrhage.
- Alzheimer’s disease.
- Degeneration of brain tissue.
- Metabolic conditions that affect brain tissue.
- Hormonal conditions that affect brain tissue.
What does a spike on an EEG mean?
Spikes or sharp waves are terms commonly seen in EEG reports. If these happen only once in a while or at certain times of day, they may not mean anything. If they happen frequently or are found in specific areas of the brain, it could mean
there is potentially an area of seizure activity nearby
.
How much does an EEG cost?
The cost of an EEG Procedure varies. It depends whether you have or don’t have insurance, and sometimes what city you live in. Costs for an EEG Test can range from
$200 to $3, 000 or more
.
