Somnambulism. Clinical characteristics and personality patterns

Area of Science:

• Neurology
• Sleep Medicine
• Psychiatry

Background:

• Sleepwalking (somnambulism) is a sleep disorder with varying clinical presentations.
• Understanding the developmental trajectory and psychological correlates of sleepwalking is crucial for effective management.

Purpose of the Study:

• To investigate the developmental course and personality patterns of adults with current or past sleepwalking.
• To differentiate characteristics between individuals with ongoing versus resolved somnambulism.

Main Methods:

• A cohort of fifty adults with present or past somnambulism complaints were assessed.
• Evaluation included developmental history, clinical course, and personality pattern analysis.

Main Results:

• Sleepwalking typically begins before age 10 and resolves before age 15.
• Current sleepwalkers, unlike past ones, initiated episodes later, experienced them more frequently and earlier in the night, with more intense symptoms.
• Current sleepwalkers displayed significant psychopathology and outward-directed behaviors, suggesting aggression management difficulties, whereas past sleepwalkers showed normal psychological patterns.

Conclusions:

• Adult sleepwalking is associated with later onset, increased frequency, and greater severity compared to childhood-resolved cases.
• Current somnambulism in adults may indicate underlying psychopathology, particularly issues with aggression.
• Findings support tailored clinical evaluation and management strategies for sleepwalking.
