Pain can cause increasing cognitive impairment. Pain can be pervasive and show up in a number of signs that staff might not initially relate to a resident's discomfort. These include the following, according to Christie Teigland, PhD, in a presentation at the recent American Association of Homes & Services for the Aging annual meeting. • Sleep disturbance, e.g., people waking up at night; • Malnutrition. People with pain tend to lose weight, Teigland noted. • Decline in social and recreational activities; • Physical function decline; • Depression and anxiety; • Increased levels of cognitive impairment; • Behavioral symptoms, especially those affecting others. A patient in pain may lash out at a caregiver, Teigland noted.
