Isolated sleep paralysis occurs in up to 7,6 % of general population, which makes it to be a common sleep disorder. Recurrent isolated sleep
paralysis (RISP) means REM (rapid eye movement) related parasomnia, which occurs recurrently during the transition between sleep and wake
that means during falling asleep or awakening. It is a transient loss of speech and voluntary movement that affects limbs and trunk muscles,
which is especially at the beginning of the accompanied by an intensive fear. This burdensome experience can be elevated by accompanying
fearful dreamy delusions, so called hypnagogic/hypnopompic hallucinations. Pathophysiological background of sleep paralysis is the continuing muscle atonia of REM sleep that persists until the full awakening. Current sleep medicine offers psychoterapeutic as well as farmacological
treatment options.
