Electroencephalography (EEG)
An EEG is used to record brain activity and helps neurologists diagnose certain disorders. Small electrodes are placed on the scalp by a technologist and a computer is used to record and view the brain activity. To obtain an optimal recording, patients are told to come in having been sleep-deprived. PNA has an EEG lab on site at the Tacoma office.

Ambulatory EEG
In an ambulatory EEG study, the patient takes a portable EEG machine home to be monitored over a set number of days. An ambulatory EEG serves the same purpose as a regular EEG, but provides doctors with a longer sample of brain activity.

Ambulatory EEG with Video
The same process as an ambulatory EEG, an ambulatory EEG with video provides doctors a visual reference with which to correlate the EEG activity when reading the recording.
