The reported largest prospective cohort study on adult sleepwalkers seen in a clinic, the results of which appeared in the journal SLEEP, involved a case-control study of 100 adult patients in whom primary sleepwalking was diagnosed from June 2007 to January 2011.
Exclusion criteria included a positive clinical history of REM sleep behavior disorder (RBD), a similar parasomnia that involves violent dream-related behaviors emerging during REM sleep.
The age of the sleepwalkers ranged from 18 to 58 years with a median age of 30. Results were compared with 100 healthy control subjects without any history of sleepwalking. More tomorrow.
