The relationship of a full range of psychiatric symptoms to EE was examined in 40 men with BPRS and SANS diagnoses of schizophrenia or schizoaffective disorder. Patients from high-EE families had significantly higher ratings of positive symptoms, anxious depression, and overall psychopathology, but not negative symptoms, than did those from low-EE families. In predicting relapses of schizophrenia, account may need to be taken of an interaction between subtle differences in symptoms and relatives' attitudes.

Objective: It has been hypothesized that patients with a diagnosis of schizophrenia who have a positive family history for schizophrenia will show greater reactivity of their symptoms to increasing levels of stress or negative affect than will patients without such a family history. In the past this hypothesis has only been tested through manipulations of negative affect in laboratory settings. In this paper we test this hypothesis using longitudinal clinical data. Method: Data were derived from an earlier longitudinal study using monthly assessments of daily stressors (Hassles Scale) and symptom measures (the Scale for the Assessment of Positive Symptoms and the Scale for the Assessment of Negative Symptoms). We compared longitudinal stress to symptom relations in 12 patients with schizophrenia for whom a positive family history of schizophrenia could be identified with 12 matched schizophrenic patients without any known family history of psychiatric illness. Results: There was evidence that patients with a family history of schizophrenia demonstrated a stronger relation between stress and total score on the Scale for the Assessment of Positive Symptoms. This difference appears to have primarily reflected a greater reactivity to stress of reality distortion symptoms in the positive family history group. The two groups did not differ in apparent reactivity to stress of the disorganization and psychomotor poverty dimensions of symptomatology. Conclusions: The results of this study provide support from a naturalistic, longitudinal clinical study for the hypothesis that reactivity to stress of some symptoms of schizophrenia may vary as a function of family history of the disorder.

The Relationship

The relationship of depression with affect deficit in schizophrenic patients continues to challenge both the clinician and the researcher. Often there is considerable difficulty in differentiating these two affect states in a reliable and valid fashion. On the observational level, depressed affect often appears somewhat restricted, having lost the full range of the euthymic state. On a subjective level, schizophrenic patients often complain of anhedonia, a defect in pleasure capacity which is shared by patients who are depressed. On the prognostic level, there is a large body of literature that links depressive features in acute schizophrenics to favourable subsequent course (Astrup & Noreik, 1966; Vaillant, 1964). We were, therefore, interested in investigating the relationship of depression with impaired affect and with positive/negative symptoms in young acute schizophrenic patients. We used a systematic multidimensional study of affect impairment among 37 young acute schizophrenic patients in a prospective, longitudinal approach over a 2-year span. In addition to a detailed assessment of the affect profile, including depression, both at baseline and on follow-up, we rated patients clinically for a positive and negative syndrome as well as general psychopathology, and we conducted premorbid and outcome measurements.

Time Point

The chapter focuses on the relationship of negative and positive symptoms in schizophrenia. Negative symptoms should be evaluated in a relation to positive symptoms both cross-sectionally and long term (prospectively/retrospectively). Two types of long-term interaction between negative and positive symptoms could be distinguished: (1) relatively synchronized, and (2) relatively desynchronized. Synchronization of negative and positive symptoms is characterized by their unidirectional long-term course. Desynchronization is characterized by their bidirectional long-term relations: (1) negative schizophrenia with minimal positive symptoms at the beginning of the disease and further progression of negative symptoms; or (2) schizophrenia with negative symptoms ‘that stopped at the very beginning’, and the later course is characterized by positive symptoms. Considering every single time point of the long-term relationship between negative and positive symptoms (cross-sectionally), the chapter describes the concept of ‘mutual/common syndromes’ (consisting of both positive and negative symptoms) at different stages of schizophrenia, including residual deficit states.

Positive And Negative Symptoms

SummaryMost investigators concur that schizophrenia is probably a heterogeneous group of disorders that share the common features of psychotic symptoms, partial response to neuroleptics, and a relatively poor outcome. The subdivision of schizophrenia into two subtypes, positive versus negative, has achieved wide acceptance throughout the world during recent years. This distinction has heuristic and theoretical appeal because it unites phenomenology, pathophysiology, and etiology into a single comprehensive hypothesis.In spite of its wide appeal, the distinction has a number of problems. These include the failure to distinguish between symptom syndromes and diseases; failure to deal with the mixed patient; failure to take longitudinal course into account; and failure to address conceptually and methodologically the distinction between positive and negative symptoms.This paper focuses primarily on the conceptual basis for two instruments designed to measure positive and negative symptoms, the Scale for the Assessment of Negative Symptoms (SANS) and the Scale for the Assessment of Positive Symptoms (SAPS), originally described in 1982. Since their description, these scales have been used in a variety of other centers. These scales are based on the hypothesis that negative symptoms represent a deficit or diminution in normal psychological functions wliile positive symptoms represent an excess or distortion of normal functions. Reliability data are now available from Italy, Spain, and Japan which suggest that these scales can be used reliably in cultural settings outside the United States. The results of these studies are summarized in this paper. In addition, a replication study involving a new sample of 117 schizophrenics collected at the University of Iowa is described. In this second study of the SANS and SAPS, internal consistency is found to be quite high in the SANS. Thus negative symptoms appear to be more internally correlated with one another than are positive symptoms. The implications of this result are discussed. A principal components analysis is used to explore the relationship between positive and negative symptoms. While the study reported in 1982 suggested that positive and negative symptoms are negatively correlated, in the present study they appear to be uncorrelated. Overall, the results suggest that the SANS and SAPS are useful comprehensive instruments for the evaluation of positive and negative symptoms. The relationship between these symptoms and external validators such as cognitive functioning or CT scan abnormalities will be reported in a subsequent investigation.

Abstract Objective: Findings on the relationship of psychiatric symptoms with performance-based and self-reported cognitive function post-stroke are inconclusive. We aimed to (1) study the relation of depression and anxiety to performance-based cognitive function and (2) explore a broader spectrum of psychiatric symptoms and their association with performance-based versus self-reported cognitive function. Method: Individuals with supratentorial ischemic stroke performed neuropsychological examination 3 months after stroke. For primary analyses, composite scores for memory and attention/executive function were calculated based on selected neuropsychological tests, and the Hospital Anxiety and Depression Scale (HADS) was used. Psychiatric symptoms and self-reported cognitive function for secondary aims were assessed using the Symptom-Checklist-90 – Revised (SCL-90-R). Results: In a sample of 86 patients [mean (M) age: 64.6 ± 9.2; Mini-Mental State Examination (MMSE), 3–7 days post-stroke: M = 28.4 ± 1.7; National Institutes of Health Stroke Scale (NIHSS) after 3 months: M = 0.7 ± 1.6] depressive symptoms (HADS) were associated with poorer memory performance after controlling for age, sex, and education (p ≤ .01). In a subsample (n = 41; Age: M = 65.7 ± 8.1; MMSE: M = 28.4 ± 1.8; NIHSS: M = 1.0 ± 1.9), symptoms of phobic anxiety (SCL-90-R) were associated with poorer performance-based memory and attention/executive function, and symptoms of anxiety (SCL-90-R) with lower attention/executive function. Higher levels of self-reported cognitive difficulties were associated with higher scores in all psychiatric domains (p ≤ .05). Conclusion: Even in relatively well-functioning stroke patients, depressive symptoms are associated with poorer memory. The results also suggest that various psychiatric symptoms are more related to self-reported rather than to performance-based cognitive function. Screening for self-reported cognitive difficulties may not only help to identify patients with cognitive impairment, but also those who need psychological treatment.

Second Generation Antipsychotics

Purpose of Review: This is a comprehensive review of the literature regarding the use of paliperidone in the treatment of schizophrenia and schizoaffective disorder. It covers the background and presentation of schizophrenia and schizoaffective disorder, as well as the mechanism of action and drug information for paliperidone. It covers the existing evidence of the use of paliperidone for the treatment of schizophrenia and schizoaffective disorder. Recent Findings: Schizophrenia and schizoaffective disorder lead to significant cognitive impairment. It is thought that dopamine dysregulation is the culprit for the positive symptoms of schizophrenia and schizoaffective disorder. Similar to other second-generation antipsychotics, paliperidone has affinity for dopamine D2 and serotonin 5-HT2A receptors. Paliperidone was granted approval in the United States in 2006 to be used in the treatment of schizophrenia and in 2009 for schizoaffective disorder. Summary: Schizophrenia and schizoaffective disorder have a large impact on cognitive impairment, positive symptoms and negative symptoms. Patients with either of these mental illnesses suffer from impairments in everyday life. Paliperidone has been shown to reduce symptoms of schizophrenia and schizoaffective disorder.

The Relationship

Of 20 patients attending a clinic for maintenance therapy of schizophrenia, seven had regular panic attacks, and these were often associated with agoraphobia and social phobia. Similar fears and avoidance in other cases were associated with paranoid ideas and negative symptoms. The relationship of panic to psychotic symptoms varied greatly. In two patients neuroleptics were associated with an increase in panic attacks.

AbstractLoss aversion is a behavioral phenomenon that describes a higher sensitivity to losses than to gains and influences decisions. Decision-making is altered in several psychopathologic states, such as in the two symptom dimensions of hypomania and negative symptoms. It has been argued that progress in our understanding of psychopathology requires a reorientation from the traditional, syndrome-based perspective to a more detailed study of individual constituent symptoms. In the present study, we made careful efforts to dissociate the relationship of loss aversion to negative symptoms, from its relationship with hypomanic symptoms. We selected a sample of 45 subjects from a healthy student population (n = 835) according to psychopathologic scales for hypomania and negative symptoms and stratified them into a control group (n = 15), a subclinical hypomania group (n = 15) and a negative symptoms group (n = 15). Participants completed a loss aversion task consisting of forced binary choices between a monetary gamble and a riskless choice with no gain or loss. We found, that these two symptom dimensions of hypomania and negative symptoms have a similar inverse relation to loss aversion as demonstrated by analysis of variance. Further research is warranted to describe the underlying psychological and neurobiological mechanisms at play. Given the partially opposing nature of hypomania and negative symptoms it further needs to be elucidated whether they are linked to loss aversion via dissociable mechanisms.
