Comorbid type 2 diabetes mellitus and hypertension exacerbates cognitive decline: evidence from a longitudinal study

Hassing, L. B.·2004·Age and Ageing

Abstract

BACKGROUND: diabetes and hypertension are two highly prevalent diseases in the old population. They are highly related such that comorbidity is common. OBJECTIVES: to examine (i) the independent impact of the respective diseases on cognitive decline in very old age and (ii) the interactive impact of the two diseases on cognitive decline. SUBJECTS: 258 individuals (mean age = 83 years), all non-demented at baseline. Of these, 128 individuals (non-cases) were free from diabetes and hypertension, 92 individuals had a diagnosis of hypertension, 16 had a type 2 diabetes mellitus diagnosis without hypertension, and 22 had comorbid diabetes and hypertension. METHOD: a population-based longitudinal study of ageing (The OCTO-Twin Study), including four measurement occasions 2 years apart. The Mini-Mental State Examination was used to measure general cognitive function. Data were analysed using SAS Proc Mixed multilevel modelling. RESULTS: longitudinal trajectories indicated a steeper decline in cognitive function related to diabetes but not related to hypertension. However, the results indicated greatest cognitive decline among persons with comorbid diabetes and hypertension. CONCLUSIONS: it is concluded that comorbidity of diabetes and hypertension produce a pronounced cognitive decline. This finding emphasises the importance of prevention and treatment of those highly prevalent diseases in the old population.

  • Six studies reported time-related changes as a continuous variable using either the MMSE or 3MS score in individuals with and without a history of diabetes.

    “Table 2 lists the six studies that reported time-related changes as a continuous variable using either the MMSE or 3MS score in individuals with and without a history of diabetes [49, 51, 52, 54, 65, 69].”
  • Studies reporting the development of future dementia reported that people with diabetes had a higher risk of all-cause dementia than people without diabetes.

    “Studies reporting the development of future dementia of these reported that people with diabetes had a higher risk of all-cause dementia than people without diabetes [56, 58, 64, 65, 67].”

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.
