The impact of smoking status on cognition and brain morphology in schizophrenia spectrum disorders.
BACKGROUND Cigarette smoking is associated with worse cognition and decreased cortical volume and thickness in healthy cohorts. Chronic cigarette smoking is prevalent in schizophrenia spectrum
Impact of smoking Behavior on cognitive functioning in persons at risk for psychosis and healthy controls: A longitudinal study
TLDR
The data suggest that UHR have fewer cognitive impairments and higher smoking cessation rates compared to patients with first-episode psychosis found in literature, and Implications to promote smoking cessation in the UHR stage need further investigation.
Cigarette Smoking and Schizophrenia: Etiology, Clinical, Pharmacological, and Treatment Implications
TLDR
Smokers with schizophrenia are more likely to have more intense positive symptoms and lower cognitive function, but diminished intensity of extrapyramidal side effects than nonsmoking patients with schizophrenia, which could suggest higher levels of baseline aggression.
An Open Trial of Metacognitive Remediation Therapy and Pharmacotherapy to Promote Smoking Cessation among Individuals with Psychotic-Spectrum Disorders
TLDR
The results from the current study suggest cautious optimism with regard to the use of MCR-Q in combination with medication for individuals with psychotic-spectrum disorders who want to quit smoking.
Emerging Evidence for the Widespread Role of Glutamatergic Dysfunction in Neuropsychiatric Diseases
TLDR
A conceptual overview of brain glutamatergic activity and peripheral interfacing is presented, including the common mechanisms that diverse diseases share when glutamate homeostasis is disrupted.

Assessment of the Association Between Cigarette Smoking and Cognitive Performance in Patients With Schizophrenia-Spectrum Disorders: A Case-Control Study
TLDR
It is shown that cigarette smoking is related to worse delayed memory performance in schizophrenia patients as well as deficits of immediate memory, visuospatial/constructional functions, and global cognition in controls.
Smoking improves divided attention in schizophrenia
TLDR
This study provides first evidence that the complex attention domain of divided attention is improved by smoking, which further substantiates the self-medication hypothesis of smoking in schizophrenia, although this has been shown mainly for sustained and selective attention.
Cigarette Smoking and Cognitive Function in Chinese Male Schizophrenia: A Case-Control study
TLDR
The results show that smoking is associated with significant cognitive impairment in both schizophrenic patients and normal controls, but the smokers with schizophrenia had a reduced level of negative symptoms, suggesting that the benefits of smoking for those with schizophrenia may be limited to certain aspects of a given clinical phenotype.
Association Between Smoking Behavior and Cognitive Functioning in Patients With Psychosis, Siblings, and Healthy Control Subjects: Results From a Prospective 6-Year Follow-Up Study.
TLDR
The study findings indicate that smoking is associated with poorer cognitive performance in patients, their siblings, and healthy control subjects compared with nonsmoking and smoking cessation may improve processing speed in patients.
