Hypothesis
The study aims to determine and compare VMR changes in diabetic and non-diabetic patients.
Conclusion
Diabetes may decrease the brain blood flow reserve, increasing the risk for vascular events.
Supporting Evidence
- Diabetic patients had a lower average VMR compared to non-diabetic patients.
- The average flow velocity change was significantly lower in diabetic patients.
- Statistical analysis showed significant differences in VMR and flow velocity between the two groups.
Takeaway
This study looked at how well blood vessels in the brain respond to changes in carbon dioxide levels in people with and without diabetes.
Methodology
A cross-sectional study using Trans-Cranial Doppler to evaluate vasomotor reactivity in 53 diabetic and 51 non-diabetic patients.
Limitations
The study excluded non-cooperative cases and those with a history of cerebrovascular diseases or other vascular abnormalities.
Participant Demographics
The mean age was 41.53 ± 17.80 years, with 66.30% males.
Statistical Information
P-Value
p = 0.02 for VMR, p = 0.04 for flow velocity
Statistical Significance
p<0.05
