Background
There is belief that water-pipe smoking is less toxic than cigarettes. However, studies indicated that it exposes patients to more toxins than cigarette smoking.
Purposive
This study aims at assessing tobacco and water pipe-related cerebral blood flow (CBF) and comparing the CBF parameters between them using transcranial Doppler ultrasonography.
Patients and methods
This cross-sectional study was conducted on 40 male smokers and 20 controls. Participants were subjected to full history and detailed clinical and neurological examination. Transcranial color coded duplex was performed.
Results
CBF parameters from either anterior or posterior circulation were significantly higher in both cigarette and shisha smokers. Higher parameters were noticed in shisha smokers. Increased cerebrovascular reactivity was one of our interesting discoveries.
Conclusion
Impaired cerebral circulation in smokers either cigarette or water-pipe, with abnormal cerebrovasculature, was suggested. These were consistent with hypoperfusion in smokers. These results were more evident in water-pipe smokers.
