Objectives: Executive function is an important cognitive function affected in many psychiatric disorders but limited data is available regarding its course in patients recovered from acute and transient psychotic disorder. The aim of this study was to assess the executive function of recovered patients of acute and transient psychotic disorder and to evaluate different factors affecting the executive function of patients recovered from acute and transient psychotic disorder. Method: This was a non-invasive, one point, comparative study where the executive function was assessed after clinical recovery from acute and transient psychotic disorder. The patients were divided into two groups (poor and fair) on the basis of their executive performance. Retrograde analyses of different factors affecting executive performance were carried out. Results: A total of 28 patients had undergone assessment on Wisconsin Card Sorting Test (WCST) out of which 13 patients had poor and 15 patients had fair executive performance. The fair executive performance group had shorter duration of psychosis, male preponderance and more years of education. Conclusion: Average duration of psychosis seems to be a reliable predictor of better or poor executive functioning.
