In analyzing over 62 million electronic medical records, researchers from Case Western Reserve University found that out of 15,770 patients with COVID-19, 810 of them also had dementia. When the researchers adjusted for general demographic factors — age, sex and race — they found that people with dementia had more than three times the risk of getting COVID-19. When they adjusted for COVID-specific risk factors like nursing home residency and underlying physical conditions, the gap closed somewhat, but people with dementia were still twice as likely to become infected. Experts and the study authors said the reasons for this vulnerability might include cognitive and physiological factors.
