EEG vs polysomnogram: The polysomnogram will check oxygen level, brain activity, breathing, movements, it will also film you. It is more comprehensive that an eeg.

EEG: Eeg uses approx 19 electrodes and is used to diagnose epilepsy, coma, encephalopathies, in olden days use to be used to diagnose tumor, stroke etc. Sleep study uses 4 channels to measure eeg (electrical activity of the brain cells). It also uses other channels like ekg, oxygen levels, muscle movements etc.
