Immigrants and dementia: Literature update.

The population of immigrants in the U.S. is increasing with older immigrants experiencing age-related decline more rapidly than the U.S.-born white population. Immigrants have a higher prevalence and risk of dementia, including undiagnosed dementia. Older immigrants face unique obstacles in terms of their cognitive health, including language barriers, economic constraints, depressive symptoms, social isolation, low acculturation to the U.S., stigma related to dementia, and lacking education about dementia. Nurses, including advanced practice registered nurses, are well-positioned to enhance immigrants' access to accurate information about dementia and to promote immigrants' timely diagnosis and treatment of dementia symptoms. Several interventions have been developed specifically for immigrant caregivers. Immigrant families need interventions that provide education about dementia, offer resources for caregivers nationally and locally, and are targeted towards specific ethnic groups.
