Abstract

fetched live from OpenAlex

Older adults are prone to have multiple chronic health conditions. The purpose of this study was to investigate whether older adults with age-related macular degeneration (AMD) who experience Charles Bonnet syndrome (CBS) are at a higher risk of developing depression and mild cognitive impairment (MCI). A total of 42 participants (31 females, 11 males; age: 68–99 years, M = 85.5 years; visual acuity [VA] in the better eye ranging from 20/70 to 20/1200) diagnosed with AMD were recruited in a vision rehabilitation center. They completed the Montreal Cognitive Assessment (MoCA) in its blind version, the Geriatric Depression Scale, and responded to questions designed to determine whether they experienced visual hallucinations consistent with CBS. Participants were then categorized into whether or not they experienced CBS, were at risk of depression or were at risk of MCI. Participants in the group experiencing CBS did not statistically show a higher likelihood of developing depression and/or MCI than those without CBS. Overall, the risk of depression (30%) was consistent with previous studies. In our sample of 42 older adults with visual impairment, 62% failed the MoCA suggesting they were at risk of cognitive decline. Our study was not able to replicate previous reports of a possible relationship between CBS and MCI in older adults with AMD; however, the observed level of possible cognitive impairment warrants further investigation. Future studies should include participants with other ocular pathologies to investigate whether a relationship among CBS, MCI, and/or depression may exist independently of AMD.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
