Association of social support with mild cognitive impairment and dementia among older women: the Women’s Health Initiative Memory Study

Women comprise approximately two‐thirds of older adults with Alzheimer’s disease in the United States. Social support may be a modifiable risk factor for cognitive impairment. However, few long‐term, large prospective studies have examined associations of various forms of social support with cognitive impairment. Therefore, we examined the association of perceived social support with incident mild cognitive impairment (MCI) and dementia among older women.
