Objective:

To investigate the clinical association factors for third, fourth, and sixth cranial nerve palsies, including demographic characteristics and impact on all-cause mortality.

Approach:
    Key Findings:
    • Mean age was 63.5 years for CN III, 57.6 years for CN IV, and 60 years for CN VI palsy groups.
    • Higher prevalence of diabetes mellitus and hypertension in CN III and VI cohorts compared to CN IV and non-palsy patients.
    • Significant differences in comorbidities and laboratory parameters among the CN III, IV, and VI cohorts.
    Interpretation:

    The study highlights demographic and clinical differences among cranial nerve palsy groups, with implications for understanding underlying risk factors.

    Limitations:
    • Retrospective nature may introduce bias.
    • Potential confounding factors not fully controlled despite propensity score matching.
    Conclusion:

    The findings provide insights into the demographic characteristics and comorbidities associated with cranial nerve palsies.
