How EEG test performed
EEG test is a painless procedure. it generally takes 40 to 60 minutes to complete.
A small metal disc called an electrode is attached to the scalp with wires, electrode scan the electrical impulse in the brain ( brain cells) and then sends a signal to the computer and records the result.
8Hz waves and higher frequency waves are showing normal results, but the wave frequency of 7Hz or lower wave frequency is an abnormal finding in awake adults.
