Anxiety symptoms in older patients frequently coexist with depression, medi
cal illness, and dementia, which complicate diagnosis and treatment. Most a
nxiety disorders do not begin in later life but are a recurrence or worseni
ng of a pre-existing condition. Anxiety should be considered in any older p
atient with depressive symptoms or somatic complaints that are not explaine
d by physical examination. Older patients may benefit from cognitive-behavi
oral therapy and relaxation training. Antidepresants, particularly selectiv
e serotonin reuptake inhibitors, are the preferred medical treatment.
