뇌손상 환자의 수면장애와 우울과의 관계

Depression and Sleep disturbance among patients with Brain Injuries

Purpose: The purpose of this study was to investigate the association of sleep disturbance and depression among patients with brain injuries. Methods: One hundred twenty three participants were recruited among patients with brain injury from a department of neurosurgery of University hospital and in a Metropolitan city during the period of July 16-August 31, 2008. Research instruments employed in this study were SPMSQ(Short Portable Mental State Questionnaire), KSS(Korean Sleep Scale) and GDSSF-K(Geriatric Depression Scale Short Form-Korean version). Results: Subjects' sleeping hours had an average of 5.92(2.01) hours at night and 0.5 hours nap during daytime. Averages of GDSS-K and KSS scores of the subjects were 8.08(3.44) and 38.24(6.47) respectively, and the two means were significantly correlated (r=.3, p<.01). Sleep deficit from previous night was also significantly correlated with depression. Percentages of sleep disturbance and depression among subjects were both 81%. Conclusion: It was found that patients with brain injuries presented relatively high sleep disturbance. Majority of the patients exhibited symptoms of depression in this study. Sleep disturbance and depression were significantly correlated, and sleep deficit from previous night was highly correlated with depression.
