Sleep requires the loss of consciousness, but is very distinct from
simply knocking your head on the wall and passing out. Sleep is an
active process by which your brain makes itself turn off consciousness
and turn on whatever weird thing it does. EEG changes in sleep also
change in well-described sleep with distinct stages.

I don't know of any disease which causes one to lose the ability to
sleep, so I can't say. Run-of-the-mill insomnia isn't that since it's
just a out-of-sync biological clock.
