Research published in The BMJ

Every study in the alzhub library that its record lists as published in The BMJ, summarised in plain English and scored out of 100.

These counts and lists are worked out from the library itself each time the page loads. A score rates how much weight a study can bear — its design, journal, evidence and recency — not whether its result is good news.

The 20 highest-scoring

  1. Medications for adults with type 2 diabetes: a living systematic review and network meta-analysis BMJ (Clinical research ed.) · 2025-08-14 · · Peer-reviewed
  2. Adherence to Mediterranean diet and health status: meta-analysis BMJ (Clinical research ed.) · 2008-09-11 · · Peer-reviewed
  3. Physical inactivity, cardiometabolic disease, and risk of dementia: an individual-participant meta-analysis BMJ (Clinical research ed.) · 2019-04-17 · · Peer-reviewed

    In this analysis of 404,840 people, physical inactivity was not associated with all-cause dementia or Alzheimer's disease once bias from reverse causation was addressed. This is a null result and does not support physical inactivity as a cause of dementia.

  4. Care in specialist medical and mental health unit compared with standard care for older people with cognitive impairment admitted to general hospital: randomised controlled trial (NIHR TEAM trial) BMJ (Clinical research ed.) · 2013-07-02 · · Peer-reviewed
  5. Video decision support tool for advance care planning in dementia: randomised controlled trial BMJ (Clinical research ed.) · 2009-05-28 · · Peer-reviewed
  6. Efficacy of treating pain to reduce behavioural disturbances in residents of nursing homes with dementia: cluster randomised clinical trial BMJ (Clinical research ed.) · 2011-07-15 · · Peer-reviewed
  7. Dementia And Physical Activity (DAPA) trial of moderate to high intensity exercise training for people with dementia: randomised controlled trial BMJ · 2018-05-16 · · Peer-reviewed

    This large randomized trial tested a moderate to high intensity aerobic and strength exercise programme in 494 people with mild to moderate dementia. The study did not find that the exercise programme improved cognitive outcomes, so it does not support exercise training as a treatment to slow dementia in this group.

  8. Community occupational therapy for older patients with dementia and their care givers: cost effectiveness study BMJ (Clinical research ed.) · 2008-01-02 · · Peer-reviewed
  9. Effect of enhanced psychosocial care on antipsychotic use in nursing home residents with severe dementia: cluster randomised trial BMJ (Clinical research ed.) · 2006-03-16 · · Peer-reviewed
  10. Multiple adverse outcomes associated with antipsychotic use in people with dementia: population based matched cohort study BMJ · 2024-04-17 · · Peer-reviewed

    This large cohort study found that antipsychotic use in people with dementia was associated with increased risks of many adverse outcomes, including pneumonia, acute kidney injury, venous thromboembolism, and stroke. These findings highlight the need for caution when prescribing antipsychotics in this population.

  11. Community based occupational therapy for patients with dementia and their care givers: randomised controlled trial BMJ (Clinical research ed.) · 2006-11-17 · · Peer-reviewed

    In this randomized controlled trial, community occupational therapy improved patients' daily functioning and caregivers' sense of competence compared with controls. The improvement was still significant at three months.

  12. Association between palliative care and healthcare outcomes among adults with terminal non-cancer illness: population based matched cohort study BMJ (Clinical research ed.) · 2020-07-06 · · Peer-reviewed
  13. Effect of reductions in amyloid levels on cognitive change in randomized trials: instrumental variable meta-analysis BMJ (Clinical research ed.) · 2021-02-25 · · Peer-reviewed
  14. Time to nursing home admission and death in people with dementia: systematic review and meta-analysis BMJ · 2025-01-08 · · Peer-reviewed

    This review of 261 studies describes how long people with dementia survive and when they enter nursing homes, with survival strongly depending on age at diagnosis. It provides prognostic information but does not test any treatment, cure, or prevention.

  15. Physical activity, cognitive decline, and risk of dementia: 28 year follow-up of Whitehall II cohort study BMJ (Clinical research ed.) · 2017-06-22 · · Peer-reviewed

    In this 28-year follow-up of over 10,000 people, physical activity was not associated with later cognitive decline or with risk of dementia. The study found no evidence that midlife physical activity reduces dementia risk.

  16. Delirium and incident dementia in hospital patients in New South Wales, Australia: retrospective cohort study BMJ · 2024-03-27 · · Peer-reviewed

    Among 55,211 matched pairs of older hospital patients (mean age 83) in New South Wales who had no recorded dementia, those who developed delirium were three times as likely to receive a new dementia diagnosis over about five years (subdistribution HR 3.00) and 39% more likely to die. Each extra episode of delirium was linked to a further 20% rise in dementia risk. The authors say this supports delirium as a 'potentially modifiable risk factor' for dementia, but the study was observational, relied on hospital diagnosis codes, and did not test whether preventing delirium lowers dementia risk.

  17. Association of ideal cardiovascular health at age 50 with incidence of dementia: 25 year follow-up of Whitehall II cohort study BMJ (Clinical research ed.) · 2019-08-07 · · Peer-reviewed

    In this cohort, a higher cardiovascular health score at age 50 was associated with a lower risk of dementia over 25 years of follow-up. It is an observational finding about risk, not proof that improving cardiovascular health prevents dementia.

  18. Multifactorial intervention after a fall in older people with cognitive impairment and dementia presenting to the accident and emergency department: randomised controlled trial BMJ (Clinical research ed.) · 2003-01-01 · · Peer-reviewed
  19. Anticholinergic drugs and risk of dementia: case-control study BMJ (Clinical research ed.) · 2018-04-25 · · Peer-reviewed

    Longer and heavier use of certain anticholinergic drugs, especially antidepressants, urological, and antiparkinson drugs, was linked to a modestly higher risk of developing dementia. This was an observational case-control study, so it cannot prove that these drugs cause dementia.

  20. Mental illness, challenging behaviour, and psychotropic drug prescribing in people with intellectual disability: UK population based cohort study BMJ · 2015-09-01 · · Peer-reviewed
