In the week ending Nov. 12, there were 2,251 deaths in the state. 21% of deaths were caused by heart disease, 19.3% were from cancer and 5.8% were from COVID-19. Additionally, 8.8% 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.
