Pathological gambling in a psychiatric sample.

OBJECTIVE: This study determines the prevalence of gambling difficulties in a consecutive sample of psychiatric inpatients and compares it with a nonpsychiatric inpatient sample. In addition, the gambling prevalence among all psychiatric disorders is analyzed. METHOD: An observational study was conducted in psychiatric patients and sex- and age-matched nonpsychiatric patients. The psychiatric group (n = 100) included all consecutive patients admitted to the psychiatric unit of our hospital. The nonpsychiatric group (n = 100) included psychiatrically healthy inpatients from any other hospital unit. The National Opinion Research Center Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Screen for Gambling Problems was used to screen for gambling behavior. RESULTS: Gambling difficulties were experienced by 3% (2% pathological gambling and 1% problem gambling) of nonpsychiatric inpatients and 9% (8% pathological gambling and 1% problem gambling) of psychiatric inpatients, including 6 with psychotic disorders, 1 with mood disorder, 1 with adjustment disorder, and 1 with eating disorder. There were no statistical differences in gambling prevalence between groups. In terms of comorbidity, patients with psychotic disorder had a higher prevalence of gambling problems than other psychiatric disorders (P = .045). CONCLUSIONS: A higher prevalence of gambling disorders was found in psychiatric inpatients than in nonpsychiatric inpatients. It may be advisable for therapists to routinely assess for gambling difficulties as part of the psychiatric evaluation.

Improvement of cognitive flexibility and cingulate blood flow correlates after atypical antipsychotic treatment in drug-naive patients with first-episode schizophrenia.

The aim of this study was to examine the changes in cognitive flexibility and associated cerebral blood flow in the anterior cingulate lobe of drug-naive patients with first-episode schizophrenia who were treated with atypical antipsychotics for 6 weeks. Single photon emission computed tomography (SPECT) images were obtained from 8 healthy subjects both at rest and while performing the flexibility subtest of the TAP (Test for Attentional Performance). SPECT images were obtained in parallel from 8 first-episode drug-naive schizophrenic patients while they were performing the same task both before and after 6 weeks of neuroleptic treatment. In the control group, an increase in the perfusion indices of the dorsal section of the anterior cingulate gyrus was observed in the activation condition. Task performance was altered and the level of perfusion of the brain region related to the task execution was significantly decreased in the patients at baseline. After treatment, there was a significant improvement in both task performance and the level of perfusion of the dorsal section of the anterior cingulate. We conclude that treatment with second-generation neuroleptics improves cognitive flexibility, and there was a relationship between such improvements and normalization of perfusion indices of the involved brain areas.

Computer-assisted cognitive remediation therapy: cognition, self-esteem and quality of life in schizophrenia.

BACKGROUND: Quality of life (QoL) is an important outcome in the treatment of schizophrenia. Cognitive deficits have an impact on functional outcomes. Cognitive remediation therapy is emerging as a psychological intervention that targets cognitive impairment, but the effect of computer-assisted cognitive remediation on neuropsychology and social functioning and wellbeing remains unclear. The aim of the current study is to investigate the neurocognitive outcomes of computer-assisted cognitive remediation (CACR) therapy in a sample of schizophrenia patients, and to measure the quality of life and self-esteem as secondary outcomes. METHODS: Sixty-seven people with schizophrenia were randomly assigned to computer-assisted cognitive remediation or an active control condition. The main outcomes were neuropsychological measures and secondary outcomes (self-esteem and quality of life). Measurements were recorded at baseline and post-treatment. RESULTS: The CACR therapy group improved in speed of processing, working memory and reasoning and problem-solving cognitive domains. QoL and self-esteem measures also showed significant improvements over time in this group. CONCLUSIONS: Computer-assisted cognitive remediation therapy for people with schizophrenia achieved improvements in neuropsychological performance and in QoL and self-esteem measurements.
