Exciting research suggests that a scan of blood vessels in the neck during mid-life could become part of detecting early signs of dementia - even before symptoms appear.
The Research
Studies indicate that Carotid Doppler Ultrasound (imaging of blood vessels in the neck) could help identify individuals at risk of developing dementia up to a decade before symptoms manifest.
Why This Matters
Dementia affects approximately 55,000 people in Ireland. Early detection is crucial because:
- Lifestyle interventions may slow progression
- Treatment can begin earlier
- Families can plan and prepare
- Research into prevention becomes more effective
What We've Seen
In our practice, we've performed carotid scans that have identified significant findings. In one case, a patient's internal carotid artery was almost completely blocked, requiring urgent vascular consultation.
Comparing this to a normal artery demonstrates why these scans can be life-changing.
The Carotid-Brain Connection
The carotid arteries supply blood to your brain. When these arteries are narrowed or blocked:
- Blood flow to the brain is reduced
- This can affect cognitive function over time
- It increases stroke risk
Who Should Consider This Scan?
You might benefit from a carotid ultrasound if you have:
- High blood pressure
- Diabetes
- High cholesterol
- Family history of stroke or dementia
- Smoking history
- Sedentary lifestyle
The Scan Itself
The carotid doppler ultrasound is:
- Non-invasive
- Painless
- Takes about 30 minutes
- Uses no radiation
