Sleep and Cognitive Impairment Associations in 170 Bipolar Disorder Patients

170 outpatients with bipolar disorder were assessed for sleep quality and cognitive performance, with 63.1% exhibiting cognitive impairment. Data includes age-grouped analysis (<50 vs. ≥50 years) and associations with insomnia and depression severity. The study uses standardized instruments like the Oviedo Sleep Questionnaire and Screening of Cognitive Impairment in Psychiatry.

Use Cases

• Analyze associations between sleep satisfaction and cognitive functioning within the younger patient age group (<50 years).
• Model the relationship between severity of depression and cognitive impairment for the older patient cohort (≥50 years).
• Compare insomnia prevalence and cognitive status across the two defined age groups.
• Investigate demographic patterns, such as the 61.8% female representation (n=105), relative to study outcomes.

Strengths

• Includes 170 patient records from a clinical study.
• Provides age-specific analysis with groups <50 years and ≥50 years.
• Uses standardized, validated instruments for sleep and cognitive assessment.

Limitations

• Small sample size of 170 patients limits generalizability and statistical power.
• Data is contained within a DOCX document, requiring extraction for computational analysis.
• Cross-sectional study design prevents causal inference from the observed associations.
