Complex mental health needs in older people living with frailty.

Frailty describes a state of health whereby people develop multiple or cumulative deficits in physiological systems over the life course, leading to vulnerability and being less able to respond to acute and/or physiological stressors, which at times may be relatively minor. Mental health should be an important consideration in the assessment and management of frailty in older people. This article provides an overview and clinical perspective on the evidence relating to frailty and mental health assessment and management.
