Hypothesis

What is the prevalence of cognitive impairment among hemodialysis patients and its relation to clinical characteristics?

Conclusion

There is a high prevalence of cognitive impairment among hemodialysis patients that adversely affects their hospitalization and life expectancy.

Supporting Evidence

  • 18.8% of hemodialysis patients showed cognitive impairment based on the MMSE.
  • Older hemodialysis patients had a higher prevalence of cognitive impairment.
  • Education level was associated with MMSE scores among hemodialysis patients.

Takeaway

Many people on dialysis have trouble thinking clearly, which can make it harder for them to take care of their health.

Methodology

The study used a cross-sectional design and administered the Mini-Mental State Examination (MMSE) to 154 hemodialysis patients and 852 healthy controls.

Potential Biases

Potential bias due to the reliance on self-reported data and the limited scope of cognitive assessment.

Limitations

The study only used the MMSE for cognitive assessment and was cross-sectional, limiting causal inferences.

Participant Demographics

154 hemodialysis patients (88 males, 66 females) and 852 healthy volunteers (314 males, 538 females), aged 30 years and above.
