Blood Pressure Fluctuations Linked to Cognitive Decline in Older Black Adults
Fluctuating Blood Pressure Linked to Cognitive Decline in Black Older Adults
New research suggests that unstable blood pressure might potentially be a risk factor for cognitive problems in Black older adults, highlighting the importance of blood pressure monitoring and management.
A study published in the journal Neurology found a connection between fluctuating blood pressure and lower scores on thinking and memory tests in Black participants. This association was not observed in white participants.
“These results suggest that fluctuation in blood pressure is a risk factor for cognitive problems beyond the negative effects of high blood pressure itself,” said Dr. Anisa Dhana, study author from Rush University in Chicago. “Older adults should be routinely monitored for their blood pressure and any changes over time so we can identify people who may have this issue and work to alleviate it, which could potentially help to prevent or delay cognitive problems.”
The study, which involved over 4,700 participants with an average age of 71, tracked blood pressure and cognitive function over an average of 10 years. Black participants showed greater variability in their systolic blood pressure (the top number) compared to white participants.
Those black participants with the highest blood pressure variability experienced a decline in cognitive function equivalent to 2.8 years of aging compared to those with the least variability. Interestingly, this association was not observed in participants taking blood pressure medication at the start of the study.While the study provides valuable insights, it’s important to note that the participants were predominantly Black and white, limiting the generalizability of the findings to othre racial groups.
“With our aging society and the prevalence of Alzheimer’s disease, identifying prevention strategies to slow the decline of cognitive skills in older adults has become a public health priority,” Dr. Dhana emphasized. “Managing blood pressure and its fluctuations is emerging as an essential risk factor that can be modified.”
This research underscores the need for further investigation into the link between blood pressure variability and cognitive health, notably in diverse populations.
Black Older Adults: unstable Blood Pressure Linked to Cognitive Decline
NewsDirectory3.com – New research sheds light on a potential link between fluctuating blood pressure and cognitive decline in Black older adults, emphasizing the importance of blood pressure management.
A study published in Neurology revealed a correlation between blood pressure variability and lower scores on cognitive tests in Black participants. This connection was not observed in white participants.
Dr. Anisa Dhana, lead author of the study from Rush University in Chicago, explained, “These results suggest that fluctuation in blood pressure is a risk factor for cognitive problems beyond the negative effects of high blood pressure itself.”
The study, which followed over 4,700 participants with an average age of 71 for approximately 10 years, found that Black participants exhibited greater variability in their systolic blood pressure compared to white participants.
Black participants with the highest blood pressure variability experienced a cognitive decline equivalent to 2.8 years of aging compared to those with the least variability. Notably, this association was absent in participants taking blood pressure medication at the study’s outset.
While acknowledging the study’s limitation of primarily focusing on Black and white participants, Dr. Dhana stressed the public health importance of these findings, stating, “With our aging society and the prevalence of Alzheimer’s disease, identifying prevention strategies to slow the decline of cognitive skills in older adults has become a public health priority. Managing blood pressure and it’s fluctuations is emerging as an essential risk factor that can be modified.”
Further research is crucial to investigate the connection between blood pressure variability and cognitive health across diverse populations.
