What is chronic microvascular ischemic changes?
Chronic microvascular ischemic changes are when there are tiny blood vessels in the brain that have ruptured or clotted. This causes very small strokes.

A "stroke" is an illness of the brain, the equivalent of a heart attack. There are two general types of strokes. An "ischemic" stroke or a "transient ischemic attack" is a …blockage of the flow of blood within the brain. This is typically caused by a blood clot within the brain. If small enough, in a "TIA", the clot is washed away or dissolved, with little aftereffects. A larger or longer-lasting blockage can cause substantial death of brain tissue. The other type is a "hemmorhagic" stroke, in which a blood vessel bursts and blood leaks into the brain.
What is Moderate cortical atrophy and scattered areas of chronic ischemic white matter changes of the brain?
'Atrophy' just means a reduction in size, due to disuse or disease. The cerebral cortex is the grey-matter (outer layer) of the brain that contains the neural cell bodies; as …opposed to the white-matter which contains myelinated axons coursing away from each cell body. 'Ischaemia' refers to oxygen starvation in the brain (e.g. from stroke). Cortical atrophy due to ischaemia is therefore a reduction in the grey-matter volume due to lack of oxygen, followed by axonal pruning.
Brain atrophy is, essentially, the shrinking of the brain. This is due to the loss of brain cells. White matter ischemic changes are a product of aging. Both are seen in patie…nts with dementia.
Having high blood pressure can greatly increase the possibility ofsuffering from a stroke or heart attack. An increase of whitematter on an MRI scan may help measure both risk…s. Ischemic changesin white matter, relative to chronic periventricular, are commonlyfound by examining MRI scans. Ischemic change in white matter canbe attributed to diabetes, a high content of fat in the blood andhigh blood pressure, which all can be attributed to raising therisk of having a stroke.
A lack of blood flow, usually from a blockage in an artery.
Chronic means of long duration. Parenchymal means related to the bulk of the organ. Chronic parenchymal changes of the brain is a non-specific description of long-standing cha…nges in how the mass of the brain looks.
Atrophy means shrinkage, and ischemic means due to lack of blood flow. This finding indicates mild shrinkage and long-term changes due to lack of blood flow, probably in the b…rain.
What does prominent deep periventricular white matter changes consistent with microvascular ischemia mean on a mri of the brain mean?
Apparently some of the white matter cells around the ventricles have died due to small blood vessel inability to supply them with enough oxygen. Basically the brain's gray …matter are our pools of information. The brain's white matter relays signals. These signals access and connect gray matter information to help us carry out physical and mental acts, from walking etc., to remembering stuff.
Chronic microangiopathic ischemic changes are areas of the brainthat show up during radiology, usually MRIs, that depict clottedoff or ruptured blood vessels. These are usuall…y related to otherserious conditions, such as diabetes, hypertension, and highcholesterol.
Insufficient blood reaching the tissues
You had an MRI of the brain which showed chronic white ischemic changes What does this mean and how is it treated?
Chronic white ischemic changes, and many other similar sounding terms, all relate to the identification of abnormal hyperintense signal foci in the white matter of brain. The …number, size, pattern and distribution of the anomalies, as well as the patient demographics and history all contribute to a differential diagnosis, whereby the radiologist reading the exam tries to attribute a cause to the anomalies. Often times, a certain number of anomalies are noted, which when all criteria are considered, seem to be part of the normal spectrum of findings. This is particularly true of older individuals, where it is a common finding. The lesions themselves are not cause for concern, and no treatment per se is necessary.
Ischemic necrosis is tissue death due to impairment of blood flow.
The nerves cells and brain cells have isolating cells around themselves that are called myelin. Demyelination means reduction of the number or size of those cells. Chronic mea…ns that the reduction lasts a long time or is permanent. Ischemic means that it is caused by lack of oxygen, which is most often due to bad blood supply. The condition will reduce the effectiveness of the conduction of nerve impulses or even cause nerve cells to get damaged too.

Chronic microangiopapthic disease is when you have problems with tiny blood vessels. This disease is common with age the tiny vessels get stiff, crackly and sometimes they get… blocked. Which can cause the vessel not to get enough blood and some of the white matter gets damaged and leads to a brain shrinkage.
