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. How we score a study.

  7. Effect of the treatment of Type 2 diabetes mellitus on the development of cognitive impairment and dementia The Cochrane database of systematic reviews · 2017-06-15 · · Peer-reviewed

    This systematic review assessed whether different strategies for managing Type 2 diabetes affect cognitive function and the incidence of dementia, based on evidence linking diabetes to cognitive impairment. The provided text does not report the results, so it is unknown whether any diabetes treatment approach reduces dementia risk.

    This randomized, sham-controlled trial tested a 6-week course of combined transcranial magnetic stimulation and cognitive training in 131 patients with Alzheimer's disease. It evaluates one treatment approach but does not establish a cure or prevention.
