Regional cerebral blood flow responses to smoking in tobacco smokers after overnight abstinence.
OBJECTIVE The purpose of the study was to determine the effects of cigarette smoking on brain regional function in a group of chronic smokers by using cerebral blood flow (CBF) measures and positron emission tomography (PET). METHOD Nineteen tobacco smokers were studied after about 12 hours of smoking abstinence. Regional CBF (rCBF) measures were obtained with PET and [15O]H2O in six consecut...
متن کاملRegional cerebral blood flow after recovery from bulimia nervosa.
When ill, women with bulimia nervosa (BN) show alterations of regional cerebral blood flow (rCBF). In this study we investigated rCBF in nine women in long-term recovery from BN (RBN, n=9), i.e. more than 1 year without bingeing/purging behavior, normal weight, stable food intake, and regular menses, and compared them with age-matched healthy control women (CW, n=13). Positron emission tomograp...
متن کاملEffects of frequent marijuana use on memory-related regional cerebral blood flow.
It is uncertain whether frequent marijuana use adversely affects human brain function. Using positron emission tomography (PET), memory-related regional cerebral blood flow was compared in frequent marijuana users and nonusing control subjects after 26+ h of monitored abstention. Memory-related blood flow in marijuana users, relative to control subjects, showed decreases in prefrontal cortex, i...
متن کاملRegional cerebral blood flow in Alzheimer's disease.
Neural networks have been successfully applied to brain perfusion images to classify patients with Alzheimer's disease from normal or other patient populations. Given the recognition that Alzheimer's disease constitutes a heterogeneous disorder, the identification of subgroups sharing common functional brain deficits would constitute a further improvement in the utility of such methods. Therefo...
متن کاملSex differences in regional cerebral blood flow.
Regional cerebral blood flow was measured by the 133-xenon inhalation method during resting in 38 healthy men and 38 healthy women matched pairwise for age in the range 18-72 years. The results showed 11% higher global flow level in the women in all ages. A similar and significant regression of flow by age was seen for both sexes. The regional flow distribution also showed some sex-related diff...
