An international team of researchers has conducted a meta-analysis of 137 clinical trials involving nearly 90,000 people to assess the migraine efficacy of 17 available drugs. Their conclusions are that four drugs in the triptan group are more effective and cheaper than newer drugs such as gepants or lasmiditan, and that the efficacy of the latter is comparable to that of paracetamol and most anti-inflammatory drugs. The results are published in The BMJ.

A study carried out in two hospitals in Denmark has compared the brain health of 120 patients admitted for covid over 18 months with that of other hospitalized patients with similar severity due to pneumonia, heart attack or need for intensive care, as well as with healthy people. The conclusions are that patients with covid worsened with respect to the latter, but did so in a similar way to other hospitalized persons. According to the authors, "although studies are needed to confirm these findings, brain health after covid-19 appears generally comparable to that of other diseases of similar severity."
