As cigarette smoking prevalence rates approach 90% in schizophrenia, an important emerging question is the role of nicotine in the disease-related disturbance in cognition. We therefore tested a total of 38 male cigarette smokers (22 schizophrenia, 16 normal control), matched on nicotine dependence, on the Attention Network Test (ANT) at three nicotine(More)
Cigarette smoking rates remain remarkably high in schizophrenia relative to smoking in other psychiatric groups. Impairments in the reward system may be related to elevated rates of nicotine dependence and lower cessation rates in this psychiatric group. Smokers with schizophrenia and schizoaffective disorder (SWS; n=15; M(age)=54.87, S.D.=6.51, 100% male)(More)
PURPOSE OF REVIEW Cognitive abilities are established as major deficits in those with schizophrenia and represent significant impediments toward successful psychosocial functioning within the community. Pharmacological treatments have historically focused on reducing the positive and negative symptoms of schizophrenia, with recent increased attention to(More)
INTRODUCTION Beneficial effects of nicotine on cognitive functioning may contribute to the markedly high rates of smoking among people with schizophrenia. A reduction in the nicotine content of cigarettes to non-addictive levels is being considered as a regulatory strategy for reducing tobacco dependence in the United States. We examined whether switching(More)
To examine retrieval-induced forgetting (RIF) in schizophrenia, subjects studied category-exemplar words taken from either strong or weak categories, and then practiced retrieval by completing category word-stems on half of the word pairs. Patients had reduced recall and recognition, but showed the expected RIF effect of better recall of unpracticed items(More)
Cigarette smoking and caffeine use are established and problematic drug-use behaviors in people with schizophrenia. Associative links between drugs of abuse may occur but the relationship between caffeine use and cigarette smoking has received little attention in schizophrenia. In this cross-cue reactivity laboratory study, we examined the effects of(More)
Exposure to smoking cues increases craving to smoke and negatively changes mood in smokers with schizophrenia (SWS). This pilot study compared reactivity to real-world smoking environments versus neutral environments in SWS (n=10) and non-psychiatric control smokers (CON; n=10). Results indicate that both SWS and CON experienced increases in smoking urges(More)
Little is known about client attitudes, especially veterans', toward the types of structured interventions that are increasingly being offered in public sector and U.S. Department of Veterans Affairs mental health clinics, nor is the possible impact these attitudes may have on treatment engagement well understood. Previous work indicates that attitudes of(More)
