In addition to metacognitive deficits, neurocognitive deficits have also been commonly observed in schizophrenia and involve decrements in capacities for attention/vigilance, verbal memory and executive function. Deficits in executive function have been found to predict concurrent and prospective assessments of poorer insight, spurring hypotheses that impairments in executive function leave persons unable to synthesize illness related experiences into a coherent and adequate story about how and why they are ill. Deficits in attention and memory may additionally obscure how historical events are connected to each other. As a whole, neurocognitive deficits may cause difficulties piecing together the individual's experience of illness into a coherent whole resulting in poor insight. Therefore, development of personal narratives using an integrated therapy would allow subjects the opportunity to better understand their illness experience, hence improving insight.
