In This Episode:
Dr. K explains what to know about cerebral small vessel disease (SVD), a very common brain condition linked to cognitive decline, balance and walking problems, dementia, and other significant health issues. She covers:
- Common terms used by radiologists to describe this condition, such as “white matter disease,””small vessel ischemia,” and others
- What is cerebral SVD
- What are the symptoms that can be caused by this condition
- Risk factors and other potential causes for cerebral SVD
- How to treat and prevent cerebral SVD
- Why it’s not usually a good idea to request an MRI to check for this condition
- What to do if you’re concerned about cerebral SVD for yourself or an older loved one

What is the literature reference to your article on the subject of this podcast (How Cerebral Small Vessel Disease Affects Most Aging Brains), which you allude to at the beginning? The impression I get is that I should be able to locate it easily, but I think I am being a bit obtuse.
Leslie Kernisan, MD MPH says
The literature references are embedded as hyperlinks in this related article: Cerebral Small Vessel Disease: What to Know & What to Do. I also list a few specific scholarly references at the end. Hope this helps.

hv 62 yr old bro, diabetic on medicines. He had a fall on 20 Feb, had fracture n clot. Admitted to nursing home for a week. Then he was OK for a month, later he started forgetting his way back home and gradually was on bed. His mri reoprt is attached, doc has prescribed cholesterol lowering drug without any test, wonder if it’s right medication.
Nicole Didyk, MD says
Sorry to hear about your brother’s difficulties.
I can’t give specific medical advice over the internet, but it may be that the MRI showed some changes in keeping with a stroke. In that case, a cholesterol lowering pill could be in order, to reduce the risk of another stroke.
Excellent resource! How about TBIs contributing?
It’s great to recognize immune disorders to contribute. Who knows?
It would be great to remedy this. I think some professionals really are at a lost understanding this if no evidence or lifestyle is contributing ( no high blood pressure, no cardiovascular issues, no diabetes, exercise is consistent. and higher).
What about low pressure contributing (100/69)? What about lower back issues like drop foot?
I personally think marking on someone’s report cognitive decline based on a MRI for mild small SVD is not helpful. Professionals assume you cannot cognate. No cognitive tests were given; one should not assume it is SVD.
Who knows what variables contribute to a fall??
Nicole Didyk, MD says
Thanks for listening to the podcast, Tom! Glad you enjoyed it.
There are many factors that could contribute to small vessel disease, but the major risk factors seem to be those associated with stroke. Age is a risk factor as well. I’m not sure how a foot drop would affect the brain, unless there’s some process that affects brain and peripheral nerves (such as diabetes). Very low blood pressure can affect blood flow to parts of the brain and cause a stroke, but chronic BP in the 100 systolic range is probbaly not harmful and may be protective.
I agree that an MRI result should not be the only factor in a diagnosis of cognitive decline. A lot more goes into the evaluation of cognition than taking a scan. You can read more about that here: https://betterhealthwhileaging.net/how-to-diagnose-dementia-the-basics/
