Post-stroke dementia is a condition where symptoms of dementia happen after a stroke.
People who consumed 2-3 cups of coffee or 3-5 cups of tea per day, or a combination of 4– 6 cups of coffee and tea had the most affordable incidence of stroke or dementia. While its possible that coffee and tea intake might be protective against stroke, dementia, and post-stroke dementia, this causality can not be inferred from the associations.
Consumption of 4-6 total cups daily was associated with lowest dangers.
Drinking coffee or tea might be related to a lower risk of stroke and dementia, according to a study of healthy people aged 50-74 released on November 16th, 2021, in the open-access journal PLOS Medicine. Drinking coffee was also related to a lower risk of post-stroke dementia.
Strokes are life-threatening events that cause 10 percent of deaths worldwide. Dementia is a general term for signs associated with decrease in brain function and is a global health worry about a high financial and social problem. Post-stroke dementia is a condition where signs of dementia take place after a stroke.
Yuan Zhang and coworkers from Tianjin Medical University, Tianjin, China studied 365,682 participants from the UK Biobank, who were recruited between 2006 and 2010 and followed them until 2020. At the beginning participants self-reported their coffee and tea intake. Over the study period, 5,079 individuals established dementia, and 10,053 experienced at least one stroke.
Individuals who consumed 2-3 cups of coffee or 3-5 cups of tea per day, or a combination of 4– 6 cups of coffee and tea had the most affordable incidence of stroke or dementia. Individuals who consumed 2-3 cups of coffee and 2-3 cups of tea daily had a 32% lower risk of stroke (HR, 0.68, 95% CI, 0.59-0.79; P << 0.001) and a 28% lower threat of dementia (HR, 0.72, 95% CI, 0.59-0.89; P =0.002) compared to those who drank neither coffee nor tea. Intake of coffee alone or in combination with tea was likewise connected with lower risk of post-stroke dementia.
The UK Biobank shows a relatively healthy sample relative to the general population which could restrict the ability to generalize these associations. Reasonably few individuals established dementia or stroke which can make it difficult to theorize rates accurately to larger populations. Finally, while its possible that coffee and tea consumption might be protective versus stroke, dementia, and post-stroke dementia, this causality can not be presumed from the associations.
