Abstract

We performed a meta-analysis to synthesize evidence on the efficacy and safety of physical exercise as an add-on therapeutic intervention for quality of life (QoL), depressive symptoms and cognition across six chronic brain disorders: Alzheimer’s disease, Huntington’s disease, multiple sclerosis, Parkinson’s disease, schizophrenia and unipolar depression. 122 studies ( = k ) ( n = 7231) were included. Exercise was superior to treatment as usual in improving QoL ( k = 64, n = 4334, ES = 0.40, p < 0.0001), depressive symptoms ( k = 60, n = 2909, ES = 0.78, p < 0.0001), the cognitive domains attention and working memory ( k = 21, n = 1313, ES = 0.24, p < 0.009), executive functioning ( k = 14, n = 977, ES = 0.15, p = 0.013), memory ( k = 12, n = 994, ES = 0.12, p = 0.038) and psychomotor speed ( k = 16, n = 896, ES = 0.23, p = 0.003). Meta-regression showed a dose–response effect for exercise time (min/week) on depressive symptoms ( β = 0.007, p = 0.012). 69% of the studies that reported on safety, found no complications. Exercise is an efficacious and safe add-on therapeutic intervention showing a medium-sized effect on QoL and a large effect on mood in patients with chronic brain disorders, with a positive dose–response correlation. Exercise also improved several cognitive domains with small but significant effects.

  • Improvements in depression are paralleled by improvements in behavioral markers of cognitive control (ES = 0.24), with a high degree of heterogeneity.

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.
