The scoring of slow wave sleep (delta sleep or stage 3) has become quite controversial due in large part to brain shrinkage. SWS is the only stage of sleep that has an amplitude requiremnet (75uv) to be defined. As the brain shrinks for many reasons (material construct) it slowly recedes from the skull. This attenuates the strength of the electric potential that can be read through a PSG or EEG recording. Thus making the signal appear that it has less amplitude than it should. Stage 3 sleep becomes stage 2. Many sleep techs are calling for the amplitude requirement for scoring stage 3 to be taken away.
