(HealthDay News) — More than half of Americans with dementia have never undergone screening of their cognitive function, according to a new study published online November 26 in Neurology.

The study included 297 people with dementia, aged ≥70, who were taking part in the national Health and Retirement Study. According to the researchers, 55.2% had never had their thinking and memory abilities evaluated by a doctor.

Married people were twice as likely to have undergone dementia screening compared to single people. The researchers also found that people with more severe cognitive impairment were more likely to have been evaluated by a doctor than those with less severe symptoms of dementia.

Factors such as race, socioeconomic status, number of children, and whether children lived close to their parents did not affect whether or not people with dementia had been screened for cognitive abilities, the study authors noted.
