TLDR
Robust cognitive deficits are present and familial in schizophrenia and psychotic bipolar disorder and Severity of cognitive impairments across psychotic disorders was consistent with a continuum model, in which more prominent affective features and less enduring psychosis were associated with less cognitive impairment.Abstract:
ObjectiveFamilial neuropsychological deficits are well established in schizophrenia but remain less well characterized in other psychotic disorders. This study from the Bipolar-Schizophrenia Network on Intermediate Phenotypes (B-SNIP) consortium 1) compares cognitive impairment in schizophrenia and bipolar disorder with psychosis, 2) tests a continuum model of cognitive dysfunction in psychotic disorders, 3) reports familiality of cognitive impairments across psychotic disorders, and 4) evaluates cognitive impairment among nonpsychotic relatives with and without cluster A personality traits.MethodParticipants included probands with schizophrenia (N=293), psychotic bipolar disorder (N=227), schizoaffective disorder (manic, N=110; depressed, N=55), their first-degree relatives (N=316, N=259, N=133, and N=64, respectively), and healthy comparison subjects (N=295). All participants completed the Brief Assessment of Cognition in Schizophrenia (BACS) neuropsychological battery.ResultsCognitive impairments among...read more

TL;DR: The results suggest that cognitive impairments may aggregate in highly familial individuals, and a hierarchical model with a "g" factor was a good fit for all subsamples.

TL;DR: In this article, the authors used the Brief Assessment of Cognition in Schizophrenia (BACS) to assess 616 individuals of European ancestry (403 psychosis, 213 controls) and quantified polygenic risk scores for coronary artery disease (PRSCAD) across 13 p-value thresholds (PT 0.5-5e-8).

TL;DR: Differences in subfield volumetric abnormalities along the anterior- posterior axis of the HP exist across psychoses and biotype typology may better reflect underlying neurobiology.

TL;DR: The findings suggest that the DAOA gene may contribute to the risk for psychotic disorders and that this gene may play a role as a modulator of executive function, probably through the dysregulation of the glutamatergic signalling.

TL;DR: The combination of muscular and neural PPI evaluations suggested distinct impairment patterns among schizophrenia and bipolar disorder patients, and simultaneous recording may contribute with novel information in sensory gating investigations.

The Positive and Negative Syndrome Scale (PANSS) for Schizophrenia
TL;DR: Review of five studies involving the PANSS provided evidence of its criterion-related validity with antecedent, genealogical, and concurrent measures, its predictive validity, its drug sensitivity, and its utility for both typological and dimensional assessment.

A new depression scale designed to be sensitive to change.

TL;DR: The construction of a depression rating scale designed to be particularly sensitive to treatment effects is described, and its capacity to differentiate between responders and non-responders to antidepressant treatment was better than the HRS, indicating greater sensitivity to change.

TL;DR: The MRS score correlated highly with an independent global rating, and with scores of two other mania rating scales administered concurrently, and also correlated with the number of days of subsequent stay in hospital.

A sharper Bonferroni procedure for multiple tests of significance
TL;DR: In this article, a simple procedure for multiple tests of significance based on individual p-values is derived, which is sharper than Holm's (1979) sequentially rejective procedure.

TL;DR: It is shown how variance-component linkage methods can be used in pedigrees of arbitrary size and complexity, and a general framework for multipoint identity-by-descent (IBD) probability calculations is developed.
