Abstract

To evaluate the predictive effects of subjective measures of physical activity (PA) and objective measures of physical fitness (PF) on dementia risk, Participants of the prospective population-based ILSE-study (*1930-1932; 12-year follow-up) were examined at three examination waves (t1 : 1993/94; t2 : 1997/98; t3 : 2005/07). 381 subjects of the original cohort (n = 500) were re-examined at t3. 29% of the subjects who were cognitively healthy at baseline received the diagnosis of mild cognitive impairment (MCI) and 7% of Alzheimer's disease (AD). Subjects were screened for physical and mental health using medical interviews, physical, and neuropsychological examinations. Participants completed a questionnaire on their current and past PA at t1. Subjects were classified as physically active if they reported a regular sport activity for at least 2 hours per week in the past year. Muscular strength (handgrip) and motor coordination (balance) served as objective indicators of PF. Subjects who passed the balance-test at t1 had a reduced risk of developing MCI/AD at t3 (OR = 0.35, 95%CI 0.19–0.66, p < 0.01) and performed significantly better on various neuropsychological measures. Muscular strength or subjective reports of PA did not predict MCI/AD development. Our results confirm the hypothesis that PF acts as a protective factor for the development of cognitive disorders. In our study, context, motor coordination served as a better predictor than muscular strength or self-rated PA. Since subjects with cognitive disorders due to cerebral and/or systemic disorders were excluded from the analyses, our findings suggest that the effect of skill-related PF extends beyond the reduction of cardiovascular risk factors.

  • Exercise is neuroprotective, delays the onset and progression, and reduces the risk for many neurodegenerative diseases, including Alzheimer's disease and Parkinson's disease.

    “Exercise has also been shown to be neuroprotective, to delay the onset and progression, and reduce the risk for many neurodegenerative diseases, including Alzheimer’s disease (AD) and Parkinson’s disease (PD) [17, 39, 58, 89, 108, 163, 193, 199].”

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.
