Social Media Bytes: Daily Associations Between Social Media Use and Everyday Memory Failures Across the Adult Life Span.

ABSTRACT:

Objectives

The prevalence of social media use in daily life is increasing; however, little is known about its cognitive costs and/or benefits. Social media use may help to offload memory to an external resource as well as to facilitate social relations, which could bolster or hinder everyday memory. Further, the relationship between social media use and memory may be moderated by age such that associations-whether positive or negative-could be exacerbated among older adults due to age-related declines.

Methods

Using an 8-day daily diary study from the Midlife in the United States Refresher cohort (n = 782, 25-75 years), multilevel models examined the impact of daily social media use, age, and their interaction on same-day and next-day memory failures.

Results

The concurrent model revealed that on days when social media use was high, individuals reported more memory failures. The lagged model further revealed that higher previous-day social media use was associated with more memory failures on the subsequent day, controlling for previous-day memory failures. These effects were not moderated by age. Post hoc analyses revealed no evidence of reverse-causation as previous-day memory failures did not predict next-day social media use.

Conclusions

Although past research has consistently shown that social engagement is a protective resource for memory, social media use may be a risk factor for memory failures for adults of any age. These findings highlight the growing importance of understanding the implications of social media use.

Project description:Typical cognitive aging may be defined as age-associated changes in cognitive performance in individuals who remain free of dementia. Ideally, the full adult age spectrum should be included to assess brain imaging findings associated with typical aging.To compare age, sex, and APOE ?4 effects on memory, brain structure (adjusted hippocampal volume [HVa]), and amyloid positron emission tomography (PET) in cognitively normal individuals aged 30 to 95 years old.Cross-sectional observational study (March 2006 to October 2014) at an academic medical center. We studied 1246 cognitively normal individuals, including 1209 participants aged 50 to 95 years old enrolled in a population-based study of cognitive aging and 37 self-selected volunteers aged 30 to 49 years old.Memory, HVa, and amyloid PET.Overall, memory worsened from age 30 years through the 90s. The HVa worsened gradually from age 30 years to the mid-60s and more steeply beyond that age. The median amyloid PET was low until age 70 years and increased thereafter. Memory was worse in men than in women overall (P <?.001) and more specifically beyond age 40 years. The HVa was lower in men than in women overall (P <?.001) and more specifically beyond age 60 years. There was no sex difference in amyloid PET at any age. Within each sex, memory performance and HVa were not different by APOE ?4 status at any age. From age 70 years onward, APOE ?4 carriers had significantly greater median amyloid PET than noncarriers. However, the ages at which 10% of the population were amyloid PET positive were 57 years for APOE ?4 carriers and 64 years for noncarriers.Male sex is associated with worse memory and HVa among cognitively normal individuals, while APOE ?4 is not. In contrast, APOE ?4 is associated with greater amyloid PET (from age 70 years onward), while sex is not. Worsening memory and HVa occur at earlier ages than abnormal amyloid PET. Therefore, neuropathological processes other than ?-amyloidosis must underlie declines in brain structure and memory function in middle age. Our findings are consistent with a model of late-onset Alzheimer disease in which ?-amyloidosis arises in later life on a background of preexisting structural and cognitive decline that is associated with aging and not with ?-amyloid deposits.
