What type of physician orders an EEG?

Most any type of physician might order an EEG if they are looking to see how the person's brain is functioning. The specialists that more often order this would be neurologists or neurosurgeons. Internists also would order this to evaluate a person having seizures, or other disorders that might indicate a problem with the brain. It is a relatively inexpensive, non-invasive procedure that would usually be done as a first step in a diagnosis of conditions involving the brain. The specialists usually work more from MRI, CT, PET scans, etc. that are much more expensive but also somewhat more diagnostically helpful.
