While primary care physicians—general internists and family physicians—care for most older people, geriatricians frequently provide the primary care for older adults who have the most complicated medical and social problems.  Also, because of their unique qualifications and training, geriatricians are often sought to provide consultations for the frailest of older persons. 

A geriatrician should be consulted when:

• An older person's condition causes considerable impairment and frailty. These patients tend to be over the age of 75 and coping with a number of diseases and disabilities, including cognitive (mental) problems.

• Family members and friends are feeling considerable stress and strain as caregivers.
