Poststroke dementia: Incidence and relationship to prestroke cognitive decline

Abstract

OBJECTIVE: To evaluate the 3-year incidence of poststroke dementia (PSD) and the influence of prestroke cognitive decline. METHODS: The authors evaluated prestroke cognitive functions in 202 consecutive stroke patients > or =40 years old using the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE), with a cut-off of 104 for the diagnosis of dementia. Six months and then annually after stroke, dementia was reassessed. The diagnosis of dementia was based on the International Classification of Diseases, 10th revision criteria in survivors who underwent a visit with a neurologist, or on the IQCODE score obtained by telephone contact with the family in survivors who did not. Statistics were performed using life-table methods. RESULTS: Thirty-three patients were excluded because of prestroke dementia. In the 169 remaining patients, the cumulative proportion of patients with dementia was 28.5% at the end of the follow-up period, with most of PSD occurring during the first 6 months. Using multivariate analysis, independent predictors of PSD were aging, preexisting cognitive decline, severity of deficit at admission, diabetes mellitus, and silent infarcts. Leukoaraiosis was an independent predictor of PSD when prestroke cognitive decline was not taken into account. The presumed etiology of dementia was vascular dementia (VaD) in two-thirds of patients and AD in one-third. CONCLUSIONS: The risk of PSD is high, and increased in patients with prestroke cognitive decline, with about one-third of patients meeting the criteria for AD and two-thirds meeting the criteria for VaD. These results confirm that, in stroke patients, an underlying degenerative pathology may play a role in the development of PSD.

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.
