Factors associated with cognitive impairment for people with mental health disorders: screening from general hospitals and an emergency care unit in Brazil

People diagnosed with schizophrenia were at very high risk of cognitive impairment. A prior history of discharges, inability to self-care, aggressive behavior, symptoms of mania and sleeping disturbances were also identified as risk factors. The interRAI EPS instrument showed to be useful to identify people with mental health disorders and substance abuse who were at risk of cognitive impairment. By early detecting these clients, professionals can refer them to adequate treatment, before symptoms increase.
