Just as one’s larger blood vessels in the heart or elsewhere can accumulate plaque, inflammation, and chronic damage over the years, so can the smaller blood vessels. In many cases, cerebral SVD seems to be a consequence of atherosclerosis affecting the smaller blood vessels that nourish brain tissue. Per a recent medical review article, specific examples of cerebral SVD include “lacunar infarcts” (which are a type of small stroke), “white matter hyperintensities” (which are a radiological finding), and “cerebral microbleeds” (which means bleeding in the brain from a very small blood vessel). Because most brain tissue appears white on MRIs, these abnormalities were historically referred to as “white matter changes.”

I will also address what you can do, if you are concerned about cerebral SVD for yourself or an older loved one.Ĭerebral small vessel disease (SVD) is an umbrella term covering a variety of abnormalities related to small blood vessels in the brain. Should you request an MRI if you’re concerned about cerebral SVD?.How can cerebral SVD be treated or prevented?.What is cerebral small vessel disease (SVD)?.In particular, I’ll address the following frequently asked questions: In this post, I will explain what all older adults and their families should know about this extremely common condition related to the brain health of older adults. Chronic microvascular changes, chronic microvascular ischemic changes.Perivascular chronic ischemic white matter disease of aging.

Now, perhaps the best technical term for what I’m referring to is “ cerebral small vessel disease.” But many other synonyms are used by the medical community - especially in radiology reports. Furthermore, these changes have been associated with problems of consequence to older adults, including: So this is a condition that older adults and families should know about. In other words, if your older parent ever gets an MRI of the head, he or she will probably show some signs of these changes. In fact, one study of older adults aged 60-90 found that 95% of them showed signs of these changes on brain MRI. Well, they don’t happen to every older person, but they do happen to the vast majority of them. What exactly are these changes, people wanted to know. This led to an immediate flurry of follow-up questions. While leading a fall prevention workshop, I mentioned that an older person’s walking and balance problems might well be related to the presence of “small vessel ischemic changes” in the brain, which are very common in aging adults. This article is about the most common aging brain problem that you may have never heard of. While a fraction of the fission products released from the reactor core will be trapped in the water of the pressure suppression pool the remainder may be dispersed within the PCV and eventually released from the PCV to the outside atmosphere by either a controlled or an uncontrolled route.Signs of cerebral small vessel disease. The presence of very hot, high pressure steam in the RPV can create a number of possible leak paths, such as through the flanges of the SRVs or the seals of the recirculation pumps, for the other radionuclides to escape into the dry well and the SC of the PCV. by condensation, plate-out, scrubbing, etc.) inside the PCV or released into the environment through PCV leaks. These aerosols and the noble gases are then further transported by flows of gas or steam until they are either retained (e.g. The fission product vapours start to condense to form small airborne particles (aerosols). In the ex-vessel configuration English translation: there is a reactor pressure vessel within the ex-vessel configurationĪfter the fission products are released from the overheated reactor core, the noble gases, as well as the fission product vapours are transported by flows of gas or steam into cooler regions of the primary containment vessel (PCV).
