Chronic cigarette smoking is associated with numerous abnormalities in brain neurobiology,
but few studies specifically investigated the chronic effects of smoking (compared to the …

Objective The mechanisms by which cessation of cigarette smoking may improve regional
cerebral blood flow (rCBF) and the details of the possible relationship remain unclear …

Cigarette smoking is often associated with dementia. This association is thought to be
mediated by hypoperfusion; however, how smoking behavior relates to cerebral blood flow …

We examined whether cerebral vascular reactivity to 5% CO2/95% O2 would be a useful,
independent measure of effects of tobacco smoking on global cerebral blood flow (gCBF) …

Background: Although approximately 80% of individuals with alcohol use disorders are
chronic smokers and despite reported associations between chronic cigarette smoking and …

Background: Neuroimaging studies reported cerebral perfusion abnormalities in individuals
with alcohol use disorders. However, no longitudinal magnetic resonance imaging (MRI) …

Middle cerebral artery (MCA) flow velocity was continuously monitored during smoking in an
observational study (n= 14) using transcranial Doppler (TCD) ultrasonography. Cerebral …

Background and objective Changes in cerebral blood flow (CBF) immediately after cigarette
smoking (CS) are still unclear. Our purpose was to evaluate the hemodynamic changes in …

Regional CBF was measured with the 133Xe inhalation technique before and thrice after
smoking marijuana of two strengths and placebo in 20 physically and mentally healthy male …

The hypothesis for this research was that regional cerebral blood flow (rCBF) would
increase following nasal nicotine administration to overnight abstinent tobacco smokers in …
