【 摘 要 】

Transcranial Doppler (TCD) is a tool that has been used widely to measure cerebral blood flow and changes in the cerebral autoregulatory mechanism that can be observed during cognitive stimulation task as changes in mean flow velocity (MFV). This cross-sectional study was to compare the anterior cerebral arteries (ACA) MFV changes during cognitive stimulation using TCD in post-stroke and control group in Neurology Department Adam Malik General Hospital. From August to December 2016, all subject underwent TCD examination to assess baseline characteristic both side of ACA; then the patients were stimulated using Stroop Task. During stimulation, we measured changes in MFV that were correlated with cerebral autoregulation in total 13 pairs of post-stroke and control recruited. Paired t-test was used to evaluate the difference in baseline and during stimulation for each post stroke and control group while independent t-test was used to determine the MFV changes difference between both groups. There were significant differences for MFV changes in each artery for control [R- ACA (p=0.001), L-ACA (p=0.001)] and post-stroke [R-ACA (p=0.001), L-ACA (p=0.001)]. Meanwhile, there was no significant difference for MFV elevation for arteries compared between groups [R-ACA (p=0.374) and L-ACA (0.272)].
