Adults with sleepwalking or night terrors exhibit distinct psychological traits. Both groups showed high hysteria scores, with night terrors linked to anxiety and sleepwalking to hostility.

Area of Science:

Psychiatry
Sleep Medicine
Psychology

Background:

Sleepwalking and night terrors are parasomnias requiring further understanding of associated psychological profiles.
Previous research has not fully elucidated the specific personality and psychoneurotic characteristics differentiating these sleep disorders.

Purpose of the Study:

To investigate and compare the personality and psychoneurotic characteristics of adults diagnosed with sleepwalking-night terrors syndrome.

Main Methods:

Prospective assessment of 12 adult patients (6 with sleepwalking, 6 with night terrors) diagnosed via clinical evaluation and polysomnography.
Utilized Eysenck personality questionnaire, hostility and direction of hostility questionnaire, and Crown-Crisp experiential index for psychological assessment.

Related Experiment Videos

Main Results:

Both sleepwalking and night terrors groups exhibited exceptionally high scores on the hysteria scale of the Crown-Crisp experiential index.
The night terrors group also scored highly on the anxiety scale, while the sleepwalking group showed high scores for externally directed hostility.

Conclusions:

Findings suggest hysterical dissociation may underlie the identified psychological features in sleepwalking and night terrors.
These results contribute to the ongoing debate on the nature of sleepwalking, including its potential forensic implications.
