The intervention was shown to be an effective and low-cost way to control blood pressure in these communities.

Dementia and COVID: What families and physicians should know

A new study published in the Journal of Alzheimer's Disease found that COVID-19 patients with dementia were more likely to experience delirium and confusion compared to those without dementia. While dementia itself was not a primary driver of mortality, other factors such as age and comorbidities played a significant role.
