Disorder with inability to fall asleep before early morning, usually after 2am, which can be more than 3 hours later than the conventional sleep time of the general population
Delayed sleep-wake phase disorder
Which medication for sleep has shortest half-life (1 hour) and therefore has lowest risk of daytime grogginess?
Zaleplon
Diminished orexin (hypocretin) transmission in the lateral hypothalamus describes pathology of this disorder
Narcolepsy
K complexes with background sleep bundles are seen in this stage of sleep
N2 NREM
(Remember K2 for K bundles in N2 REM)
Alpha activity is seen during this stage of sleep
N1 of NREM
Delta waves are seen in this stage of sleep
N3 of NREM
