There were 475 deaths with heart disease listed as the underlying cause reported in Illinois during the week ending December 4, a 4.8 percent decrease from the previous week, according to The Centers for Disease Control and Prevention.
In the week ending December 4, there were 2,490 deaths in the state. 19.1 percent of deaths were caused by heart disease, 18.9 percent were from cancer and 20.5 percent were from COVID-19. Additionally, 10.1 percent of deaths were from Alzheimer’s disease and dementia.
Studies show doctors and medical examiners may underreport Alzheimer’s disease and dementia-related conditions as the underlying cause of death on death certificates, according to the National Institute on Aging.
Once infected, older adults with dementia are likely to develop a more severe and dangerous illness. The diseases which make an older adult more vulnerable to COVID-19 are age-associated chronic conditions, according to the Bright Focus Foundation.
