COVID-19–related hospitalization is associated with an increased risk of both hemorrhagic and ischemic stroke, with the greatest danger soon after infection, per a study published last week on the preprint server Research Square. The study, conducted from March 2020 through May 2022, also suggested that being vaccinated for COVID-19 is associated with a lower likelihood of stroke. “COVID-19 requiring hospitalization confers an acute, time-limited increase in stroke risk, of a magnitude somewhat lower than that observed after pneumonia,” wrote the authors, from University of Haifa and Carmel Medical Center in Israel. “These findings support targeted cerebrovascular surveillance following hospitalization for respiratory infection.” The data have not yet been peer-reviewed. Stroke risk 23% higher after COVID hospital stay Past research has indicated that a COVID-19 infection resulting in a hospital stay increases the risk of stroke. An observational study from 2022, for example, found that people hospitalized for COVID-19 were 17.5 times more likely to experience stroke. For this preprint study, the scientists followed up with 1.2 million people aged 50 and older who had never had a stroke for roughly two years. They also matched 11,974 people who experienced stroke to 119,740 people in a control group without stroke, all...

Yin and colleagues followed four UK Biobank cohorts of around 320,000 to 328,000 participants enrolled in 2006-2010 and tested whether self-reported weekly mobile phone call time predicts cardiovascul...

A target trial emulation compared stroke and bleeding risks after apixaban vs warfarin in stage 4-5 chronic kidney disease with atrial fibrillation.

Greater variation in blood pressure between research visits was associated with a higher risk of death in a study of more than 57,000 UK Biobank participants. Variation in some blood pressure measures was also associated with stroke. The findings were presented at the Annual Meeting of the European Association for the Study of Diabetes (EASD) in Milan, Italy, Sept. 28–Oct. 2.

Insomnia is not only associated with poor sleep and reduced daytime functioning, but may also be an indicator of increased health risks. An international review by the European Academy of Neurology, in collaboration with MedUni Vienna, shows a link to stroke, hospital admissions and several neurological and mental health conditions. The findings were published in the high ranking journal “Sleep Medicine Reviews”.

Down syndrome-moyamoya syndrome is a high-risk phenotype associated with delayed recognition and increased odds of stroke at presentation.

Insomnia is associated with a 26% higher risk of stroke and 28% higher odds of hospital admission, according to new research in Sleep Medicine Reviews. The researchers say the findings support recognizing insomnia as an important marker of brain, mental and general health.
