New Study Finds Risk of Contracting COVID-19 was Twice as High for People with Dementia

Findings were published in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association on Feb. 9

CEDAR RAPIDS, February 9, 2021 – Using electronic health record data from 61.9 million American adults, researchers at Case Western University found the risk of contracting COVID-19 was twice as high for people in the study with dementia than for those without it — while among those in the study with dementia, African Americans had close to three times the risk of being infected with COVID-19 as Whites did. The findings were published in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association on Feb. 9.

These findings, though preliminary, suggest a frightening reality of the vulnerabilities associated with living with dementia. It has been speculated since the beginning of the pandemic that – because of the vulnerabilities associated with the disease – individuals with dementia are at an increased risk of contracting COVID-19. Now, the credible data published in the Alzheimer’s Association’s journal, Alzheimer’s & Dementia shows a clear connection.

In addition, the Alzheimer’s Association has emphasized that dementia symptoms can also put a person at higher risk. These symptoms may make a person forget to wear a mask, physically distance from others or frequently clean their hands, which further increases risk. It is likely not dementia itself that increases risk of COVID-19, but rather the symptoms of dementia that make a person more vulnerable. Living with Alzheimer’s or other dementia can lead to a higher likelihood of living in a long-term care facility as well, resulting in higher COVID-19 risk.

More research is needed to understand exactly what is happening in the brains of individuals with dementia that may be making them more susceptible to COVID-19. The Alzheimer’s Association and representatives from more than 30 countries have formed an international consortium to study the short- and long-term consequences of COVID-19 on the brain and nervous system in people at different ages, and from different genetic backgrounds. The Alzheimer’s Association is funding the initial work of the consortium.
