Insights on brain health, connection, and the science behind meaningful conversations.
A 2025 Behavioral Sciences study of 452 older adults found that familiarity lowered perceived risk of AI companion technology, while expected helpfulness raised positive emotional response.
A 2024 Journal of Voice systematic review of 23 studies and 1,050 older adults found that speech-language pathology meaningfully improved presbyphonia, age-related voice weakness.
A 2021 SSM – Population Health systematic review of 25 studies found that digital technology can reduce social isolation in older adults when tools are accessible and supported with simple training.
A 2021 Journal of the American Geriatrics Society mixed-methods study found regular peer outreach visits lowered loneliness and depression in older adults over 24 months.

A 2023 JAMA Network Open study found severe loneliness and limited social networks were linked to higher all-cause mortality in U.S. adults 50+.
A Korean Frailty and Aging Cohort Study found that older adults who saw friends only monthly had roughly 5x higher odds of being frail compared to those with daily friend contact.
A large PLoS Medicine study found that moderate and severe loneliness were associated with higher all-cause mortality in older adults.
A 2024 study found widowhood was linked to immediate functional decline and higher one-year mortality risk in older adults with dementia or cancer.
A 2022 meta-analysis found a cognitive advantage in bilingual older adults, and AI that speaks any language can help families create more daily language engagement.
A 2023 study found that over half of older adults with dementia experienced worsening cognitive impairment during periods of social isolation.
A 2020 study found that peer companionship reduced depression, anxiety, and perceived burdensomeness in socially disconnected older adults.
