Investigating this could further the understanding of surrounding concepts and reasons for impaired awareness. Recognising emerging or diminishing awareness could facilitate discussions about diagnosis and appropriate post\u2010diagnostic support.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Using longitudinal data from the Improving the experience of Dementia and Enhancing Active Life (IDEAL) cohort, awareness in community\u2010dwelling people with mild\u2010to\u2010moderate dementia was assessed at three timepoints over 2\u00a0years. A validated checklist was used to evaluate awareness of difficulties associated with dementia. We examined changes in awareness for people with low awareness at baseline, and used case\u2010matching to describe differences in characteristics between people who gained awareness, and those who continued with low awareness.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>At baseline, 83 people from a sample of 917 showed low awareness. The majority of those remaining in the study at later timepoints had gained awareness, some as late as four or more years after diagnosis. Case\u2010matched comparisons revealed few distinguishing characteristics: cases with stable low awareness had similar or better cognitive and functional ability than those who gained and retained awareness at 12 and 24\u00a0months, but may have had more co\u2010morbidities.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Self\u2010reported awareness of difficulties can change and may increase over time in people with mild\u2010to\u2010moderate dementia. There may be individual reasons for ongoing low awareness, not explained by cognitive or functional ability. This challenges the view that a single record of low awareness represents a fixed disease\u2010related symptom, and highlights the complex, individual and dynamic nature of awareness.<\/jats:p><\/jats:sec>","DOI":"10.1002\/gps.5702","type":"journal-article","created":{"date-parts":[[2022,3,5]],"date-time":"2022-03-05T06:14:00Z","timestamp":1646460840000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Changes
