A peer-reviewed Viewpoint in Brain Health argues that physical activity should be prescribed and followed up as part of psychiatric care, rather than offered only as general lifestyle advice. The authors cite evidence for improvements in mood and possible cognitive and functional benefits, while noting that findings for schizophrenia cognition rely on modest trials and that some dementia-risk evidence is observational.
A peer-reviewed Viewpoint in Brain Health argues that clinicians should prescribe physical activity as a structured part of psychiatric care, with an individualized activity plan and follow-up, rather than mention exercise only as general lifestyle advice. The authors point to evidence that exercise can reduce depressive and anxiety symptoms and may support cognition, while stressing that evidence strength varies by outcome and population.
The Viewpoint was written by Carl Zhou and Nicholas Fabiano of the University of Ottawa’s Department of Psychiatry and Stanley Wong of the University of Toronto’s Department of Psychiatry. Drawing on randomized trials, meta-analyses and cohort studies, they recommend that a prescription specify the type, frequency, intensity and duration of activity, account for safety, and include follow-up. The article makes a case for a clinical approach; it does not report a new clinical trial testing the prescription model.
The authors describe the evidence for mood outcomes as comparatively strong. They cite research indicating that physical activity interventions can reduce depressive symptoms, anxiety and psychological distress. A 2024 network meta-analysis of randomized trials found reductions in depression symptoms with walking, jogging, yoga and strength training; effects were generally larger at higher intensity. Dose-response analyses cited in the Viewpoint suggest benefits may occur below public-health activity targets, at about 75 minutes of moderate activity per week. That estimate is not a guarantee of an individual response.
The article also discusses people with schizophrenia and other severe mental illness, who face high rates of sedentary behavior and cardiometabolic disease. Meta-analytic evidence suggests aerobic exercise may improve global cognition in schizophrenia, with possible gains in working memory, attention and social cognition. Wong cautioned that those cognitive findings draw on a limited set of modest trials. The authors say exercise could address psychiatric symptoms, cognition and physical health together, but larger studies are needed to establish the scale and reliability of cognitive effects.
A More Practical Role for Exercise
Recasting exercise as a planned treatment component could change how clinicians discuss activity with people whose mental health conditions affect energy, motivation or daily functioning. A specific, graded plan gives patients and clinicians something more actionable than a broad instruction to exercise, and follow-up can help adapt the activity to a person’s circumstances and progress.
The potential relevance is particularly clear in severe mental illness, where the Viewpoint describes overlapping needs in mental health, cognition and physical health. But the article does not establish that exercise replaces medication or other care, nor that every patient will experience the same gains. Its proposal is to make activity part of an individualized care plan, alongside attention to access, safety and patient capacity.
The authors also note that activity need not begin at a full guideline target. A small, sustainable starting point—such as a short walk or chair-based movement—may be more feasible for someone struggling with symptoms. This is presented as a practical prescribing approach, not as a proven minimum dose for all psychiatric conditions.

Evidence Behind the Prescription
The Viewpoint links exercise to brain function through several possible pathways, including blood-vessel health, metabolism, inflammation and neuroplasticity. It describes the muscle-brain axis, in which contracting muscles release signaling molecules called myokines that interact with pathways related to mood and cognition. The authors present this as one explanatory model among several, not a complete account of how activity affects the brain.
For memory, the article points to a 2011 randomized trial in older adults by Erickson and colleagues. That trial found aerobic exercise increased the volume of the anterior hippocampus and improved memory. The Viewpoint distinguishes this trial evidence from broader links between physical activity and cognitive aging, dementia or Alzheimer’s risk, which rely substantially on observational studies and cannot by themselves establish cause and effect. The World Health Organization includes physical activity in its recommendations for reducing dementia risk.
The authors cite WHO guidance of 150 to 300 minutes of moderate-intensity aerobic activity per week for adults, or 75 to 150 minutes of vigorous activity, plus muscle-strengthening activity on at least two days. They argue that prescriptions can build toward those targets gradually. Frailty, unstable heart or respiratory symptoms, or recent falls may call for medical assessment, supervision or a pause, according to the Viewpoint.
“The evidence we reviewed supports something more deliberate: a prescription that names the type of activity, the frequency, the intensity, the duration, the safety considerations, and a plan for follow-up, just as we would for a medication.”
— Carl Zhou, University of Ottawa Department of Psychiatry
Limits in the Clinical Evidence
The Viewpoint synthesizes existing research; it does not test whether a formal exercise-prescription system improves outcomes compared with usual psychiatric care. It is also not clear from the report how much benefit patients can expect from a particular activity plan, how long effects persist, or which forms and doses work best for different diagnoses and levels of impairment.
Evidence is not equally strong across claims. The authors characterize mood findings as better supported, while cognitive benefits in schizophrenia rest on a limited number of modest trials. Associations between activity and lower dementia risk are largely observational, so other factors may contribute. The report does not provide a single effect size for the overall prescription approach or establish that the cited weekly activity dose suits every patient.
Safety and access also vary between individuals. The article says some health conditions or recent falls may require clinical assessment or supervision, but the report does not set out a patient-specific protocol. The proposal to use exercise-mimicking drugs for people facing major barriers to movement remains theoretical in this account; the authors say such agents would be an adjunct, not a substitute for safe, accessible physical activity.
Building Stronger Psychiatric Trials
The authors call for adequately powered studies to test cognitive outcomes in schizophrenia, where existing trials are limited in size and number. Further research will also be needed to clarify which activity types, intensities and durations are most useful for particular patients, and how best to build prescription and follow-up into routine psychiatric care.
For now, the Viewpoint’s recommendation is for clinicians to consider a graded, safety-aware plan tailored to the patient, with gradual progression rather than an abrupt demand to meet activity guidelines. The report does not announce a new guideline or policy change, and no implementation timeline is given. Whether structured prescribing leads to better functional outcomes in everyday psychiatric practice remains to be tested.
Key Questions
What is the new development?
A peer-reviewed Brain Health Viewpoint argues that clinicians should prescribe physical activity as a structured part of psychiatric care, with an individualized plan, safety considerations and follow-up. It is a research-based recommendation, not a report of a new clinical trial.
Which mental health outcomes may improve with exercise?
The authors cite evidence that physical activity interventions can reduce depressive symptoms, anxiety and psychological distress. They also discuss possible cognitive benefits, including in schizophrenia, but say those findings need larger trials.
Does the article recommend a specific weekly exercise target?
It cites WHO guidance for adults of 150 to 300 minutes of moderate activity or 75 to 150 minutes of vigorous activity per week, along with muscle strengthening on at least two days. The authors favor starting at a manageable level and progressing gradually; the target is not presented as a prescription for every individual.
How strong is the evidence for cognitive benefits in schizophrenia?
Meta-analytic evidence suggests aerobic exercise may improve global cognition, with possible benefits in specific cognitive areas. Wong said the findings rely on a limited set of modest trials, so larger, adequately powered studies are needed.
Is exercise proposed as a replacement for psychiatric medication?
No. The Viewpoint argues for treating activity as a planned part of care; it does not say exercise should replace medication or other treatment. It also says exercise-mimicking agents, if developed, would be an adjunct for people facing major barriers to movement, not a substitute for safe activity.
