Abstract

CONTEXT: Hippocampal volume is lower than expected in patients with schizophrenia; however, whether this represents a fixed deficit is uncertain. Exercise is a stimulus to hippocampal plasticity. OBJECTIVE: To determine whether hippocampal volume would increase with exercise in humans and whether this effect would be related to improved aerobic fitness. DESIGN: Randomized controlled study. SETTING: Patients attending a day hospital program or an outpatient clinic. PATIENTS OR OTHER PARTICIPANTS: Male patients with chronic schizophrenia and matched healthy subjects. INTERVENTIONS: Aerobic exercise training (cycling) and playing table football (control group) for a period of 3 months. MAIN OUTCOME MEASURES: Magnetic resonance imaging of the hippocampus. Secondary outcome measures were magnetic resonance spectroscopy, neuropsychological (Rey Auditory Verbal Learning Test, Corsi block-tapping test), and clinical (Positive and Negative Syndrome Scale) features. RESULTS: Following exercise training, relative hippocampal volume increased significantly in patients (12%) and healthy subjects (16%), with no change in the nonexercise group of patients (-1%). Changes in hippocampal volume in the exercise group were correlated with improvements in aerobic fitness measured by change in maximum oxygen consumption (r = 0.71; P = .003). In the schizophrenia exercise group (but not the controls), change in hippocampal volume was associated with a 35% increase in the N-acetylaspartate to creatine ratio in the hippocampus. Finally, improvement in test scores for short-term memory in the combined exercise and nonexercise schizophrenia group was correlated with change in hippocampal volume (r = 0.51; P < .05). CONCLUSION: These results indicate that in both healthy subjects and patients with schizophrenia hippocampal volume is plastic in response to aerobic exercise.

  • Three months of aerobic exercise training increases hippocampal volume in healthy individuals and in patients with schizophrenia by 12% and 16%, respectively.

    “It has been shown that three months of aerobic exercise training increases hippocampal volume in healthy individuals and in patients with schizophrenia by 12% and 16%, respectively [235].”

    From Neurotrophic Factor BDNF, Physiological Functions and Therapeutic Potential in Depression, Neurodegeneration and Brain Cancer (2020) · cites this paper as [235]

    The claim reverses the percentages. The Abstract and “CHANGE IN HIPPOCAMPAL VOLUME AND EXERCISE” section report a 12% increase in patients with schizophrenia and a 16% increase in healthy controls after three months of aerobic exercise. (LLM, conf=0.95)

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured
  • In people with schizophrenia, potential positive effects on mental health and cognitive symptoms have been suggested to be related to increases in hippocampal volume, but these findings in mental disorders have not been replicated in a recent meta-analysis of RCTs.

    “Among people with schizophrenia, the potential positive effects on mental health and cognitive symptoms have been suggested to be related to increases in hippocampal volume [87], yet these findings in mental disorders have not been replicated in a recent meta-analysis of RCTs [8].”

  • Aerobic training can increase hippocampal volume in schizophrenic and healthy subjects.

    “and can be increased by aerobic training of both schizophrenic and healthy subjects' (397).”

    From Lack of Exercise Is a Major Cause of Chronic Diseases (2012) · cites this paper as [397]

  • Aerobic exercise interventions have been shown to increase hippocampal volume in patients with schizophrenia.

    “AE interventions have also been shown to increase hippocampal volume in patients with mild cognitive impairments (ten Brinke et al., 2015), schizophrenia (Pajonk et al., 2010), and multiple sclerosis (Leavitt et al., 2014).”
  • Growth in hippocampal volume and, in some cases, improvements in working memory performance are correlated with higher concentrations of NAA.

    “N-acetylaspartate (NAA) is a metabolite indicative of neuronal integrity and a number of AE studies have demonstrated that the growth in hippocampal volume (Pajonk et al., 2010; Erickson et al., 2012; Gonzales et al., 2013; Wagner et al., 2015) and in some cases, improvements in working memory performance (Erickson et al., 2011) are both correlated with higher concentrations of NAA.”

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.
