Associations Between Neuromotor and Neurocognitive Functioning in Adults with Schizotypal Personality DisorderReynolds, Felicia D. 05 1900 (has links)
Individuals diagnosed with schizotypal personality disorder (SPD) exhibit patterns of cognitive deficits in (1) attention (Lees-Roitman, Cornblatt, Bergman, Obuchowski, Mitropoulou, Keefe, Silverman, & Siever, 1997), (2) memory (Bergman, Harvey, Lees-Roitman, Mohs, Margerm, Silverman, & Siever, 1998), (3) executive functioning (Cadenhead, Perry, Shafer, & Braff, 1999), and recently (4) neuromotor functioning (Neumann & Walker, 1999), similar to individuals with a diagnosis of schizophrenia. Furthermore, recent research suggests a link between neuromotor and cognitive functioning in schizophrenia spectrum disorders (SSDs) (Neumann & Walker, 2003). The current study is an extension of research on non-drug-induced neuromotor disturbances in individuals with SPD and examines how such disturbances covary with neurocognitive measures. Approximately thirty-three adults (18-65) were rated for SPD symptoms. Motor assessments included a computerized motor task and finger tapping test. Cognitive assessments included measures of attention, verbal and visual memory, and executive functioning. Consistent with previous research, the SPD group displayed significant right hand (left hemisphere) motor disturbances (i.e., increased force and force variability) compared to healthy controls after excluding all cases reporting a history of head injury. In addition, results indicate significant associations between motor, cognitive, and symptom variables. Consistent with previous research, neuromotor functioning and the relationships between motor and cognitive functioning varied as a function of Time of Day (TOD) of testing. Understanding the relationship between neuromotor and neurocognitive functioning may help elucidate the neural systems that contribute the symptoms characteristic of SSDs.

The relationship of dissociation to borderline and schizotypal personality syndromesStockdale, Gary D. January 2001 (has links)
Borderline and schizotypal personality constructs were compared as predictors of dissociation for 971 nonclinical university undergraduates who completed 11 self-report behavior inventories. Structural equation modeling and multiple regression were used to (a) test the hypothesis that the quantitative interaction of borderline and schizotypal constructs would be the strongest predictor of dissociation and (b) evaluate each construct alone as well as their additive effect for prediction of dissociation. The interaction hypothesis was rejected; the quantitative interaction was only a substantively trifling and statistically nonsignificant predictor of dissociation. In a commonality analysis, the additive borderline and schizotypal effect was equivalent to schizotypy alone and marginally larger than the borderline effect alone for the prediction of dissociation. However, all three effects separately were substantial predictors; thus, dissociation is an untenable discriminator for the borderline and schizotypal constructs. Finally, when schizotypy was compared directly to the borderline construct such that the common variance was distributed dependent upon comparative predictive power (i.e., beta weights), schizotypy was greatly superior to the borderline construct for dissociative predictability. Consequently, reconsideration of the existing paradigm that dissociation is more strongly associated with the borderline construct than with schizotypy is warranted. / Department of Psychological Science

Childhood cat bites and disorganized symptoms of schizotypy in adulthoodKolpakova, Jenya 01 May 2013 (has links)
During recent years of schizophrenia research, many etiologies have been emphasized, some of them implicating infectious and autoimmune diseases. Many different infectious agents have been examined, but the root seems to stem from the secondary autoimmune deregulation, which can be caused by different infectious agents. Among the effects that autoimmune deregulation has on the body, one prominent effect is on the brain, resulting in either severe or mild encephalitis. The mild encephalitis that has been implicated as one of the causes of schizophrenia-spectrum disorders has been associated with different pathogens, many of which can be transmitted by the household cat. Thus in the present research we have used the schizotypy personality construct model as an analog for schizophrenia spectrum disorders, and the relationship between current schizotypy and childhood household cat interactions were examined. An online questionnaire was completed by 356 undergraduate students and assessed the current schizotypy using the Schizotypal Personality Questionnaire Brief Revised (SPQ-BR), as well as questions about cat ownership and cat bites (puncturing skin) prior to age 13. While no significant relationship was found between childhood cat ownership and current schizotypy, individuals endorsing a cat bite prior to age 13 (N = 66) reported a significantly higher level of current overall schizotypy, which was largely driven by the Disorganized factor of the SPQ-BR.. This relationship should be explored further by examining the antibodies and sera of individuals with the schizophrenia spectrum disorder.

The Relative Sensitivity Of An Olfactory Identification Deficit In Individuals With Schizotypal Personality FeaturesKamath, Vidyulata 01 January 2007 (has links)
Olfactory identification deficits have received recent attention as a potentially useful endophenotype for schizophrenia. Examination of this deficit in individuals with schizotypal personality features (SPF) offers an alternative approach to multiple confounds present when examining individuals with schizophrenia. The aim of the current study was to compare the relative sensitivity of performance on measures of olfaction identification and sustained attention to the presence of SPF. Twenty-six undergraduates were defined as having SPF based on scoring in the top 10% of the Abbreviated Schizotypal Personality Questionnaire (SPQ-B; mean age 19.6, SD = 1.1; 62% female). These individuals were compared to twenty-six controls (scoring lower than half a standard deviation above the mean; mean age 19.8, SD = 1.6; 62% female). All participants were administered the Schizotypal Personality Disorder (SPD) section of the Structured Clinical Interview for DSM IV Axis II Personality Disorders (SCID-II). In addition, participants were administered the Brief Smell Identification Test (B-SIT) and a six-minute degraded-stimuli Continuous Performance Test (CPT). Group differences in performance indices of the CPT did not approach statistical significance. Similarly, there were no statistically significant group differences for males or females in performance on the B-SIT. Correlational analyses examined cognitive performance with a dimension score derived by summing quantitative ratings from the SPD items on the SCID-II. The SPD dimension score showed a statistically significant positive correlation with several performance indices of the CPT, including omission errors (rs(52) = .51, p ≤ .001) and commission errors (rs(52) = .38, p ≤ .005). In contrast, the B-SIT scores were not correlated with the SPD dimension score for males or females. Contrary to our hypothesis, results from the current study suggest that olfactory identification deficits may not represent a robust endophenotype consistently found in samples with schizotypal personality features. With regard to sustained attention, our differential findings suggest that schizotypal traits may be more adequately assessed through an interview by trained clinicians who use clinical judgment to determine the presence of phenotypic aspects of SPD (e.g., SCID-II), rather than relying on self-report measures (e.g., SPQ-B). Implications as well as limitations and future directions of these findings are discussed.
