For patients not covered by health insurance, an EEG typically costs $200-$700 or more for a standard EEG -- or up to $3,000 or more if extended monitoring is required.
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.
Average out-of-pocket costs for electroencephalogram (EEG) tests, which can be used to diagnose conditions such as epilepsy, increased from $39 to $112. For MRI scans, they increased from $84 to $242.
This includes long-term EEG (12 to 72 hours) at an average of £366 per test, or video telemetry EEG at a cost of around £2,000 per day (for a 5- to 10-day monitoring period). Additional costs because of uncontrolled seizures might include unplanned trips to the emergency department, costing around £133 per attendance.

MRI has a higher spatial resolution than electroencephalography (EEG). MRI with hyperintense lesions on FLAIR and DWI provides information related to brain activity over a longer period of time than a standard EEG where only controversial patterns like lateralized periodic discharges (LPDs) may be recorded.
EEG identifies brain signal that correlates with depression and anxiety.
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.
An EEG can find 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: Brain tumors. Brain damage from head injury.
Certain other patterns indicate a tendency toward seizures. Your doctor may refer to these waves as "epileptiform abnormalities" or "epilepsy waves." They can look like spikes, sharp waves, and spike-and-wave discharges.
An EEG typically is covered by health insurance when medically necessary to diagnose or monitor a problem, or during surgery.
EEG referrals are currently accepted for patients with a clinical diagnosis of seizures, where the result will assist in seizure or syndrome diagnosis and may determine the need for further investigation and/or anticonvulsant medication.
The EEG recording must be analysed by a neurologist, who then sends the results to your doctor. It is important to make a follow-up appointment with your doctor. In many cases, the test results are sent to your doctor within 48 hours of the test. Treatment depends on the diagnosis.
Cost and Health Insurance
The estimated national average for the cost of a sleep-deprived EEG is $930, however, the cost can vary depending on where the procedure takes place, your state of residence, and other factors.
What happens after an EEG? After your EEG, the technician will remove the electrodes and clean your scalp. Your hair and skin may feel sticky, so you'll want to wash your hair at home. You can drive and return to your usual activities unless your healthcare provider says you shouldn't.
Medicare categorizes EEGs of all types as diagnostic lab tests and pays for 100 percent of their cost. To be eligible for this coverage, your health care provider must order it and certify that it is medically necessary. Both your physician and the lab or clinic that conducts the EEG must accept Medicare assignment.
Can anxiety cause abnormal EEG? Long-term anxiety and panic attacks can cause your brain to release stress hormones on a regular basis. This can increase the frequency of symptoms such as headaches, dizziness, and depression. All of which can alter the EEG.
EEG can also detect abnormal brain waves after a head injury, stroke, or brain tumor. Other conditions such as dizziness, headache, dementia, and sleeping problems may show abnormal brain patterns.
An EEG test only gives information about the electrical activity in your brain. It doesn't show if there's any damage or physical abnormalities in your brain. An MRI can do this.
If abnormalities on the routine EEG are found, such as focal spikes and generalized spike waves, the risk of seizure recurrence increases two times. However, the routine EEG has its limitations as its accuracy to detect abnormalities after a FSUS has a sensitivity of 17% and specificity of 95% (7).
A normal EEG means I do not have epilepsy. Many patients with epilepsy have a normal EEG between attacks. An abnormal EEG means I have epilepsy. Many people without seizures have mild abnormalities on EEG.
EEG can be normal in organic diseases and abnormal in psychiatric diseases. Typical EEG findings in neuropsychiatric syndromes point to specific diagnosis. Soft EEG changes are common in psychiatric disorders and do not indicate organicity.
Special imaging tests, such as electroencephalography (EEG), can detect the effects of depression in the brain. The tests allow doctors and researchers to study the electrical activity of the brain.
Why Use an EEG Test for Headaches? EEGs are not a standard part of a headache exam. But your doctor may order one to look for signs of seizures, which can cause symptoms similar to those associated with migraine or other types of headaches. Some people also have seizures with their headaches.
