- What dictates
one's perceptions of sleep quality in general and insomnia in
particular?
- Are the
perceptions of sleep quality isolated from fundamental physiologic
sleep regulation mechanisms?
- Are the
standard PSG measures for physiological sleep not refined enough
to reveal the underlying biological disturbance associated with
the elements of insomnia?
- Is PSG
brainwave monitoring fundamentally unable to detect the brain
changes that are most indicative of underlying brain sleep regulation
mechanisms?
One must always
ask questions like these and retain a skepticism of the measures
being used, their specificity and sensitivity, as well as their
effect on the phenomenon being measured. For these reasons, the
use of PSG measures in relation to insomnia and the refinement
of sleep scoring is a continuing scientific pursuit.
