There were less than 10 deaths from Alzheimer's disease reported in Montana in the week ending Dec. 3, making up less than 4.4% of total deaths by all causes in Montana, according to The Centers for Disease Control and Prevention.

In the week ending Dec. 3, there were 229 deaths in the state. 21.8% of deaths were caused by heart disease, 17.9% were from cancer and less than 4.4% 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.
