Abstract

This cross-sectional study examines relationships among the constellation of psychiatric syndromes in Alzheimer's disease (AD) as a function of dementia severity in 1155 patients with probable AD. The frequency of major depression decreased in severe stages, while agitation, aggression, and psychosis were more frequent in late stages. Major depression was associated with anhedonia, sleep disorders, depressed mood, low self-esteem, anxiety, and hopelessness in mild/moderate and severe stages. Agitation was associated with aggression and psychosis in mild/moderate stages, and psychosis was associated with aggression in moderate/severe stages. In addition, there was a constellation of psychiatric symptoms (e.g., anxiety, wandering, irritability, inappropriate behavior, uncooperativeness, emotional lability) associated with agitation, aggression, and psychosis, which varied according to the severity of the dementia, suggesting a progressive deterioration of frontal-temporal limbic structures. Education and race were independently associated with psychosis. However, while education was associated with psychosis in mild/moderate stages, race was associated with psychosis in moderate/severe stages.

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.
