Effect of insomnia in the major depressive disorder

BMC Neurol. 2022 Sep 10;22(1):341. doi: 10.1186/s12883-022-02869-x.

ABSTRACT

BACKGROUND: People with sleep problems are more likely to have mental disorders. This study aimed to assess the effect of insomnia on the prognosis of patients with major depressive disorder (MDD).

METHODS: We divided the patients into three groups according to the Insomnia Severity Index (ISI) scores. In addition, we compared the results of the Hamilton Depression Scale (HAMD) and Symptom Checklist-90 (SCL-90) scores. We evaluated the effect of insomnia at the 2nd, 4th, and 8th-week follow-up on the prognosis of MDD.

RESULTS: Fifty-five patients between 19 and 58 years old, with a diagnosis of MDD via the Structured Clinical Interview for the Diagnostic and Statistical Manual-5 (DSM-5). The ISI scores of the moderate and severe group decreased significantly (P < 0.05) in the 2nd week compared to the baseline. The HAMD scores in all groups improved significantly in the 2nd week.

CONCLUSIONS: This study was inspired to assess insomnia as a comorbid disorder for patients with MDD, which may bring poor treatment consequences.
