Dementia Incidence Is Higher In Black People, A New Study Revealed

A study carried out by the researchers at the University College London, and King’s College London discovered that dementia incidence is higher in black people in the UK, in comparison with the other ethnic groups in the region. On the other hand, this condition is not common among the people of British Asian origins, the scientists say.

The new research, issued yesterday in the Clinical Epidemiology journal, is the first to compare dementia rates among different ethnic groups across the United Kingdom.

“What we found suggests that the rates of people receiving a diagnosis may be lower than the actual rates of dementia in certain groups, particularly among black men,” said Dr. Tra My Pham, one of the participants in the study, and a researcher at the UCL’s Institute of Epidemiology and Health.

Even though the experts can’t explain why the people with a British Asian background are not exposed to dementia, the scientists noticed that black people are more exposed to this condition.

Dementia incidence higher in black people

“It is concerning that black people appear to be more at risk of dementia but less likely to receive a timely diagnosis,” the researchers said.

As for the British Asian situation regarding dementia, the study’s author said that “perhaps British Asians do have a lower risk, or they may only be less likely to be diagnosed when they develop it.”

The new study analyzed the data of more than 2.5 million people, including 66,083 who had dementia, between 2007 and 2015.

According to the research, British Asian women across the UK present dementia rates by 18% lower than white women, while black women by 25% higher.

In men, the situation is similar, with black men presenting a dementia incidence by 28% higher in comparison with white men. As for the Asian men, they have a dementia rate of 12% lower than the British white men.

“The report suggests that black men and women in the UK may face the combined impact of a greater likelihood of developing dementia while being less likely to receive a formal diagnosis,” concluded Dr. Alison Evans from the Alzheimer’s Research UK.
