Cognitive impairments in schizophrenia are a major contributor to the inability to function adequately in everyday life that is commonly seen in people with schizophrenia. There has been substantial attention paid to cognitive impairments as determinant of these functional deficits and our understanding of the subtleties of the relationships between cognitive impairments and disability has been refined considerably as a result. In this chapter we discuss the measurement of cognition in schizophrenia, its role as a determinant of disability, and treatment efforts to date.

Though effective interventions have proven elusive, the literature continues to grow rapidly. To date, lengthy, multifaceted interventions have shown the most promise.

Cognitive Enhancement in Schizophrenia: Pharmacological and Cognitive Remediation Approaches

Unadjusted mean MCCB cognitive composite scores are plotted by study and week of assessment through week The line thickness is proportional to the study sample size, and assessment time points for each study are denoted by markers. Individual study results are from separate mixed-effects repeated measures models of the change from baseline through week 24, with a fixed categorical effect for visit and a continuous fixed covariate for the baseline score, assuming an unstructured covariance matrix. In the overall model, visit was nested within a random study effect. Least squares mean change from baseline through week 24 is plotted by level of practice effect as calculated by the T-score change in the cognitive composite from screening to baseline. Results are from a mixed-effect repeated measures model with a continuous fixed covariate for the baseline score and a categorical effect for visit nested within a random study effect, assuming an unstructured covariance matrix.

Cognitive impairment is a core feature of schizophrenia, which is predictive for functional outcomes and is, therefore, a treatment target in itself. Yet, literature on efficacy of different pharmaco-therapeutic options is inconsistent. This quantitative review provides an overview of studies that investigated potential cognitive enhancers in schizophrenia.

Furthermore, since the medications used for cognitive enhancement have limited efficacy, the issue of cognitive enhancement still remains a clinically unsolved challenge. Some studies have reported selective cognitive improvement in patients with schizophrenia following galantamine treatment. Newer antipsychotics, including paliperidone, lurasidone, aripiprazole, ziprasidone, and BL, have also been reported to exert cognitive benefits in patients with schizophrenia. However, no beneficial effects on cognitive function were observed with dopamine agonists in patients with schizophrenia. The efficacies of nicotine and its receptor modulators in cognitive improvement remain controversial, with the majority of studies showing that varenicline significantly improved the cognitive function in schizophrenic patients. Several studies have reported that N -methyl- d -aspartate glutamate receptor NMDAR enhancers improved the cognitive function in patients with chronic schizophrenia. Raloxifene, a selective estrogen receptor modulator, has also been demonstrated to have beneficial effects on attention, processing speed, and memory in female patients with schizophrenia.

Cognitive deficits are core features of schizophrenia that are critical determinants of poor functional outcome. Until recently, the development of novel pharmacologic treatments that specifically target these deficits has been impeded by a lack of consensus about which domains of cognition should be covered and how they should be measured in clinical trials. This review summarizes the rationale for the MATRICS Initiative, some of its achievements to date, and promising pharmacologic targets for the cognitive deficits of schizophrenia.

Она сказала ему, что их брак исчерпал себя, что она не собирается до конца дней жить в тени другой женщины. Вой сирен вывел его из задумчивости. Его аналитический ум искал выход из создавшегося положения. Сознание нехотя подтверждало то, о чем говорили чувства.

Cognitive Deficits in Schizophrenia

 Из какого именно места в Штатах? - спросил. - Они ищут, господин. - Очень хорошо. Сообщите, когда узнаете .

В центре помещения из пола торчала, подобно носу исполинской торпеды, верхняя часть машины, ради которой было возведено все здание. Ее черный лоснящийся верх поднимался на двадцать три фута, а сама она уходила далеко вниз, под пол. Своей гладкой окружной формой она напоминала дельфина-косатку, застывшего от холода в схваченном морозом море. Это был ТРАНСТЕКСТ, компьютер, равного которому не было в мире, - шифровальная машина, засекреченная агентством. Подобно айсбергу машина скрывала девяносто процентов своей массы и мощи под поверхностью.

 Ни за что на свете.  - Он засмеялся.  - Супружеская пара без секретов - это очень скучно.

    Schizophrenia is a psychiatric disorder characterized by continuous or relapsing episodes of psychosis.
