Did you know that…..
Somnambulism usually occurs in the first one to three hour of sleep, stage 3 or 4 NREM sleep (also called deep sleep ) ?
Episodes last from seconds to many minutes, and are characterized by sudden awakening, blank or confused stares, incomplete arousal with poor responsiveness to people, and amnesia for the episode.
Somnambulism involves clumsy walk during which objects usually are avoided. The child appears confused but not frightened.
This disorder are almost always self-limited, though sporadic episodes may occur for years.
When somnambulism persists to adolescence and adulthood an underlying disorder should bee considered.
