There were 197 deaths from Alzheimer's disease reported in Texas in the week ending Dec. 24, making up 5.8% of total deaths by all causes in Texas, according to The Centers for Disease Control and Prevention.

In the week ending Dec. 24, there were 3,404 deaths in the state. 22.5% of deaths were caused by heart disease, 19.7% were from cancer and 7.5% were from COVID-19. Additionally, 14.9% 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.
