Description Cognitive dysfunction is a core component of depressive disorder. Cognitive impairments impact on patient functioning and negatively influence quality of life, return to work and ability to perform adequately at work. The findings show a mild impairment of more cognitive domains. Some of the cognitive deficits may be associated with the severity of psychopathological symptoms of depression. Patients with depressive disorder show a lower global cognitive performance, which means a global diffusion impairment of cognition. According to another hypothesis the depressive disorder is associated with a more pronounced impairment of specific cognitive domains, mostly with impairment of executive and memory functions. Cognitive dysfunction occurs in acute depression and can persist into remission. The alleviation of affective symptoms is often not paralleled by an equal improvement of cognition. With every episode there is a decrease in cognitive function and that inter-episode cognitive function is related to the number of previous episodes. Cognitive deficits are qualitatively similar in schizophrenia and bipolar and unipolar depression However, the severity of impairment differs between these disorders, with the most severe deficits seen in patients with schizophrenia, followed by bipolar disorder, and the least severe deficits noted in individuals with depressive disorder. The mostly used screening tools for measuring cognitive dysfunction in other psychiatric disorders, especially dementia, are not sufficiently sensitive to detect cognitive dysfunction in depression. Further, patient's subjective experience of cognitive dysfunction is not always related to performance on objective neuropsychological measures. Nowadays cognitive batteries more specific to affective disorders have been developed. A promising screening tool is the THINC-it, which includes subjective and objective measures of cognitive function. The THINC-it is yet free downloadable and easily used by tablets and laptops.
