Quality of life (QOL) has been reported to be impaired in patients with major depressive disorder (MDD), even after remission according to symptom rating scales. Although a relationship between QOL and neurocognitive dysfunction has been reported during depressive episodes, little is known about this relationship in remitted MDD patients. The aim of the present study was to investigate the relationship between QOL and neurocognitive dysfunction in patients with remitted MDD while controlling for confounding factors. Forty-three remitted MDD patients were assessed with neuropsychological tests and QOL, which was measured by a short-form 36-item health survey. The neurocognitive performances of the patients were compared with those of 43 healthy controls. We next evaluated the relationships between neurocognitive impairments, clinical factors, and QOL. Remitted MDD patients had poorer neurocognitive performances than healthy controls for psychomotor speed, attention, and verbal memory. Residual depressive symptoms were strongly associated with QOL. Delayed verbal recall was associated with general health perceptions, which are part of the QOL assessment, even after the effects of the residual depressive symptoms were considered. The results may indicate that clinicians should try to detect neurocognitive dysfunctions that may interfere with QOL using neurocognitive assessments in their daily practice.
