Deficits in cognitive functions are ubiquitous in schizophrenia. Nearly all patients with this disorder experience deficits in neurocognitive domains including attention, memory, speed of processing, reasoning and problem solving and social cognitive domains including theory of mind, emotion recognition, social cue recognition, etc. [1]. These deficits precede the onset of first psychotic episode [2] and persist through episodes of psychotic exacerbation [3] and relative quiescence [4]. Importantly, they are consistently associated with patients’ social and occupational functioning—nearly 20–60 % of the variance in their functioning is explained by their performance on tests of cognitive functions [5]. Schizophrenia causes substantial disability—indeed it accounts for 0.5 % of all-cause disability adjusted life years (DALY) [6]. Given that cognitive deficits associated with schizophrenia contribute considerably to disability, public health significance of addressing the challenge of cognitive deficits of schizophrenia cannot be overemphasized.
