Abstract Objectives: Depression is a disorder causing cognitive deficits including impairments in attention, memory, psychomotor and executive functions. In the present study, it is aimed to assess cognitive domains of patients with the diagnosis of depression with Neurobehavioral Cognitive Status Examination (COGNISTAT), compare the test results with healthy controls and investigate the association of test results with depression.  Materials and Methods: Seventy depression patients and 40 healthy controls recruited in the study were assesed by Hamilton Depression Rating Scale (HDRS) and Hamilton Anxiety Rating Scale in order to determine the severity of depression and anxiety and by COGNISTAT test in order to determine the cognitive performance.  Results: Depressive patients needed longer time in order to complete calculation sub-domain of COGNISTAT and scored lower in spatial performance, repetition total score and reasoning performance compared with the healthy controls. Calculation performance time and HDRS scores indicating the severity of depression were found to be positively correlated.  Conclusion: Depression is a disorder accompanied by cognitive impairments. COGNISTAT test, a short and easy to apply test, is a clinically practical assessment tool which can evaluate multiple cognitive domains. It is a suitable choice which can be used for evaluation and research purposes in depression.
