Effects of bright light on cognitive and sleep–wake (circadian) rhythm disturbances in Alzheimer‐type dementia
Abstract
Twenty‐seven patients with Alzheimer‐type dementia (ATD) were treated with bright light therapy in the morning for four consecutive weeks. The cognitive state of each patient was evaluated with the Mini‐Mental‐State Examination (MMSE) and circadian rhythm with actigram before and after therapy for all of the patients and those of two groups divided by the severity criteria of the Clinical Dementia Rating. The therapy improved the circadian rhythm disturbances. Although the therapy caused no remarkable effects on dementia severity, it improved the MMSE scores, especially in the early stages of ATD. These results suggest that bright light therapy improved the circadian rhythm disturbances and then bettered the cognitive state in early‐stage ATD.

“some studies indicate that morning light therapy may improve circadian rhythms and Mini-Mental State examination (MMSE), Cohen-Mansfield Agitation Inventory (CMAI) and Behaviour Pathology in AD Rating Scale (BEHAVEAD) scores, particularly in the early stages of dementia, and that, even in severe cases of dementia, it improves circadian and behavioural symptoms, most notably agitation and overall”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
