OBJECTIVES: This study is designed to investigate prevalence and risk factors of
insomnia in TBI. This study has also tried to explore the connection between
insomnia with neuroanatomical localization of TBI as well as depression.
DESIGN: Prospective study.
MATERIALS AND METHODS: All eligible participants were evaluated initially after
two week interval for first 4 weeks and monthly interval subsequently till one
year. Demographic and injury characteristics of the participants were assessed on
a self-designed semi structured performa. Interviews focused on assessment of
severity of TBI, insomnia and depression using GCS, ISI and PHQ-9 respectively.
RESULTS: Total 204 patients were included, mean age was 33.34 years. 40.2%
participants were found to have insomnia. None of the demographic variables were
associated with insomnia except severity and duration of TBI. Moderate TBI
patient (70.73%) had significantly higher occurrence of insomnia than the mild
cases (19.67%) (P=0.000, df 1). First three month after TBI witnessed more than
half (63.41%) of those patient who had insomnia. This was found statistically
significant (P<0.017). Neuroanatomical localization was also correlated with
insomnia. Cerebral contusion was the most common (40.24%) site of impact. Almost
half (42.42%) of the patients with insomnia had multiple contusions. 32.84% of
the study population had depression. No significant correlation could be
established between depression and insomnia.
CONCLUSION: Insomnia is a prevalent condition after TBI requiring more clinical
and scientific attention as it may have important repercussions on
