Abstract: Posttraumatic stress disorder (PTSD) is often accompanied with cognitive malfunctions, such as deficit in attentional sustain, biased attention towards trauma-related information, biased memory for traumatic events, and impairment in declarative memory and autobiographical memory. More evidences have been accumulated in recent years and these cognitive malfunctions in PTSD are proposed to be related with the deficit in executive control. Though it needs further studies for justifying this uniform explanation, executive function can be a good starting point for filtering and treatment of PTSD in a practical sense

Key words: posttraumatic stress disorder (PTSD), executive function, cognitive function
