  • The negative symptoms of schizophrenia include volitional (motivational) impairment manifesting as avolition, anhedonia, social withdrawal, and emotional disorders such as alogia and affective flattening. Negative symptoms worsen patients' quality of life and functioning. From the diagnostic point of view, it is important to differentiate between primary negative symptoms, which are regarded as an integral dimension of schizophrenia, and secondary negative symptoms occurring as a result of positive symptoms, comorbid depression, side effects of antipsychotics, substance abuse, or social isolation. If secondary negative symptoms overlap with primary negative symptoms, it can create a false clinical impression of worsening deficit symptoms and disease progression, which leads to the choice of incorrect therapeutic strategy with excessive dopamine blocker loading. Different longitudinal trajectories of primary and secondary negative symptoms in different schizophrenia stages are proposed as an important additional discriminating factor. This review and position paper focuses primarily on clinical aspects of negative symptoms in schizophrenia, their definition, phenomenology, factor structure, and classification. It covers the historical and modern concepts of the paradigm of positive and negative symptoms in schizophrenia, as well as a detailed comparison of the assessment tools and psychometric tests used for the evaluation of negative symptoms.

  • Negative symptoms in schizophrenia include avolition, anhedonia, asociality, alogia and affective blunting. These symptoms correlate strongly with clinical and functional outcomes, but respond poorly to conventional treatments. Research on the origins and mechanisms of negative symptoms can potentially advance the development of interventions. In this Review, we outline important points of convergence for phenomenological and neurobiological evidence. First, we summarize how negative symptoms are conceptualized and how these psychopathologies manifest in clinical and subclinical populations. Next, we critically review theoretical and empirical models of negative symptoms. We propose that the ‘trait with state-elevation’ properties of negative symptoms make them particularly useful for identifying individuals who may be at risk of developing psychosis and for predicting the onset of psychosis. Finally, we suggest that future research should use sophisticated technology and longitudinal designs to capture both inter-individual and intra-individual variability in negative symptoms and to improve diagnosis and treatments. Negative symptoms in schizophrenia correlate with clinical and functional outcomes but respond poorly to treatment. In this Review, Chan et al. summarize theoretical and empirical models of negative symptoms and propose that negative symptoms might be informative for early identification of at-risk individuals.

22. The Negative Symptoms of Schizophrenia - Karger Publishers

  • Aug 17, 2011 · Negative symptoms have been considered to be specific to schizophrenia or a subtype of schizophrenia: the deficit syndrome.

  • Abstract. Negative symptoms have been considered to be specific to schizophrenia or a subtype of schizophrenia: the deficit syndrome. In other words, these symptoms have been considered to be categorically different from other forms of human behavior and experience, whether they occur in healthy persons or patients with other psychiatric disorders. In this paper, we advocate a dimensional approach to negative symptoms, which is supported by two main arguments. First, enduring negative symptoms can even be observed in a variety of psychiatric disorders and they are not specific to schizophrenia. Second, we review evidence that negative symptoms show a continuous distribution from apparently healthy subjects to those with a fully developed clinical syndrome. Although the evidence does not allow for a definite decision concerning the dimensional distribution of negative symptoms, it certainly justifies exploring a dimensional approach with respect to its clinical and scientific utility. Understanding negative symptoms as a variation of normal mental processes will strengthen the development of neurocognitive models and treatment approaches.
