| Popis: | Background: Diabetics have a 3-fold risk for cardiovascular diseases compared with non-diabetics. This study was designed to evaluate cerebral hemodynamic changes related to type 2 diabetes mellitus (DM) with transcranial Doppler ultrasonography (TCD). TCD is a highly sensitive and specific method of quick bedside assessment of cerebrovascular circulation hemodynamics. Patients and Methods: In a prospective study, we compared a group of 100 patients with the diagnosis of type 2 diabetes mellitus (aged 48 to 67 years) and an age- and sex-matched control group of 100 healthy subjects without diabetes mellitus. We measured flow velocities (Vm) and the Gosling pulsatility index (PI) of the middle cerebral artery (MCA). Results: The rate of TCD abnormalities was significantly higher in diabetic patients than in healthy control subjects (55% vs. 11%, P< 0.05). The PI was significantly higher in diabetic patients than in healthy controls (P< 0.001). Atherosclerotic changes were found in 34.0% and 71.4% of patients suffering from diabetes for < 5 and ≥5 years, respectively. Conclusion: This study suggests that TCD is a useful marker for the detection of diabetic cerebrovascular changes. The duration and type of diabetes were found to have an impact on the development of pathologic cerebrovascular changes. |
