There were 425 deaths with heart disease listed as the underlying cause reported in Illinois during the week ending July 23, a 2.4% increase over the previous week, according to The Centers for Disease Control and Prevention.

In the week ending July 23, there were 2,090 deaths in the state. 20.3% of deaths were caused by heart disease, 19.8% were from cancer and 7.4% were from COVID-19. Additionally, 8.3% 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.
