Bilateral tachistoscopic word perception of stutterers and normal subjects

Bilateral tachistoscopic procedures were utilized to investigate the visual half-field preferences of 15 stutterers and a group of 15 normal controls. Statistical analyses indicated a right visual half-field preference for the control group. In contrast, a significant visual half-field preference was not revealed for the stuttering group. However, further analysis revealed that a significantly larger proportion of stutterers, compared to controls, demonstrated a left visual half-field preference. Results indicated reversed cerebral processing for the stuttering group as compared with the control group.     

Comparing neurocognitive impairment in schizophrenia and bipolar I disorder using the Screen for Cognitive Impairment in Psychiatry Scale

The purpose of this study was to compare the psychometric properties of the Screen for Cognitive Impairment in Psychiatry (SCIP) when applied to patients diagnosed with schizophrenia (n = 126) or bipolar I disorder (n = 76), and also to compare the cognitive impairment in both samples of patients and a control group (n = 83) using the SCIP and a complete neuropsychological battery. The SCIP is a scale intended to quickly and easily assess cognitive impairment in patients with severe psychiatric disorders. The results showed firstly that, in terms of internal consistency, temporal stability, dimensional structure, and criterion-referenced validity, the SCIP provides reliable and valid scores at an equivalent level in both schizophrenia and bipolar I disorder samples. Secondly, it showed that differential cognitive impairment between the two patient groups occurs only in verbal memory, although the effect size of the difference is small. Finally, compared with the control group, cognitive impairment was present at all levels in both groups of patients using both the SCIP and the neuropsychological battery, which indicates that the SCIP is a good screening tool for cognitive deficits in schizophrenia and bipolar and useful in clinical practice for healthcare professionals.     

Evaluation of the attentional capacities and working memory of early and late blind persons

Although attentional processes and working memory seem to be significantly involved in the daily activities (particularly during navigating) of persons who are blind and who use these abilities to compensate for their lack of vision, few studies have investigated these mechanisms in this population. The aim of this study is to evaluate the selective, sustained and divided attention, attentional inhibition and switching and working memory of blind persons. Early blind, late blind and sighted participants completed neuropsychological tests that were designed or adapted to be achievable in the absence of vision. The results revealed that the early blind participants outperformed the sighted ones in selective, sustained and divided attention and working memory tests, and the late blind participants outperformed the sighted participants in selective, sustained and divided attention. However, no differences were found between the blind groups and the sighted group in the attentional inhibition and switching tests. Furthermore, no differences were found between the early and late blind participants in this set of tests. These results suggest that early and late blind persons can compensate for the lack of vision by an enhancement of the attentional and working memory capacities.     

Prospective correlates of early (30 day) readmissions on a Cardiothoracic Surgery Service

Known to vary widely among hospitals for unclear reasons, early readmissions are associated with higher mortality and are suspected to frequently be due to inadequate discharge preparation/planning. It has been previously documented that the strongest and most consistent predictor of early readmissions in CHF patients is chronic cognitive impairment, and compensatory assistance with adherence on discharge improves early readmission rates. Prospective observational study. The present investigation examined multiple putative perioperative predictors of early readmission in a hospitalized Cardiothoracic Surgery Service. A subtest of the Mini-Cog, Short Term Memory, was the strongestunivariate predictor of early readmissions (p < .001), but the overall Mini-Cog (p = .024), Age (p = .045), Number of Admissions over the Preceding Year (p = .036), an Anxiety Scale (p = .035), Years of Education (p = .055) and a Depression Scale (p = .056) also demonstrated covariation. In a Logistic Regression, only Short Term Memory survived as a predictor variable (p = .007), correctly classifying 76% of patients. Chronic cognitive impairment is a predictor of early readmissions in Cardiothoracic patients. A brief bedside exam interpreted in medical context may permit identification of patients requiring familial assistance for adherence on discharge.
