Did you know that blood pressure plays a direct role in the brain’s health?
A groundbreaking study published in Hypertension earlier this year [van den Kerkhof et al., 2024] demonstrated how higher blood pressure is directly linked to the integrity of the blood-brain barrier. The researchers found that elevated blood pressure weakens the blood-brain barrier, allowing harmful substances to infiltrate the brain. This breakdown sets the stage for inflammation and neurodegenerative processes.
Why does this matter? Because the blood-brain barrier acts as the brain’s fortress. When it’s compromised, the risk of conditions like Alzheimer’s and vascular dementia rises.
To underscore this connection, another large international study spanning four major cohorts [Ward et al., 2024, JAMA Neurology] revealed that blood pressure is a key driver of frailty trajectories that precede dementia by over a decade. The study tracked nearly 30,000 participants and showed that frailty—a state often exacerbated by poorly managed hypertension—was strongly associated with future dementia risk.
Key Findings:
Higher blood pressure = weaker blood-brain barrier integrity, as shown by the Hypertension study.
Frailty linked to poor vascular health, including blood pressure variability, predicts dementia risk years before cognitive symptoms appear.
Blood pressure management is a critical lever in protecting the blood-brain barrier, reducing frailty, and preventing cognitive decline.
What can we do?
Maintaining optimal blood pressure levels in midlife can significantly reduce the risk of later-life dementia. Combined with proactive strategies like vascular health monitoring, personalized interventions can help preserve both cognitive health and longevity.
At BrainKey, we work to quantify and assess brain vascular health, providing insights into blood-brain barrier integrity and brain aging. By tracking these factors, we aim to empower physicians and individuals to take control of their brain health.

Takeaway: Blood pressure isn’t just about heart health—it’s deeply intertwined with the brain’s resilience and cognitive longevity.
