Huntington’s disease (HD) is a progressive brain disease that typically starts to show symptoms between the ages of 30 to 50, when people are in the prime of life. It’s also heritable, meaning anyone who has a parent with HD has a 50% chance of getting it. HD has historically been thought of as more common among those of White ancestry, but new data challenges this, suggesting comparable rates in Black individuals. Racial and ethnic health inequalities are well documented in North America, with Black and Latino individuals found to be less likely to receive neurological care, even when socioeconomic and insurance payer factors are controlled for. How, then, does this affect HD gene carriers?
Delayed diagnosis for Black people living with HD in North America
Until now, questions around racial health disparities in HD have received little attention, but a new study from Adys Mendizabal and colleagues from UCLA has begun to address this.
Adys and her team explored racial disparities in HD care by looking at data from over 4,000 North American HD gene carriers in the ENROLL-HD database.
