    The Wilson et al. loneliness-and-dementia study (823 older adults, Archives of General Psychiatry) was published in 2007, not 2012; matches the article's own reference list.

    After

    A 2007 study by Wilson and colleagues published in Archives of General Psychiatry, following 823 older adults over four years, found that lonely individuals had a 64% increased risk of developing clinical dementia.

Archives of General Psychiatry, 64(2), 234-240). No stale occurrence found in the FAQ. Backfilling record with confirmed correct text; no further edits needed.
