Cognitive dysfunction is the loss of intellectual abilities that can range from mild to severe disturbance and affect an individual’s attention, thinking, memory, executive function, reasoning, visual-spatial function, language, and psychomotor speed. The purpose of this review paper is to carry out a current understanding of cognitive dysfunction in schizophrenia as well as their relationship with the other aspects of illness. The present review deals with empirical studies from January 2005 to March 2015 searching through Pub Med database and Google Scholar, and 96 articles were found appropriate on the basis of their titles and abstracts.
