There were less than 10 deaths with COVID-19 listed as the underlying cause reported in Montana in the week ending May 21, making up less than 9.2% of total deaths by all causes in Montana, according to The Centers for Disease Control and Prevention.

In the week ending May 21, there were 109 deaths in the state. 19.3% of deaths were caused by heart disease, 26.6% were from cancer and less than 9.2% were from COVID-19.

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.
