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 means 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.

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

What does hyperintense signals in the bifrontal subcortical white matter mean?
Hyperintense signals in the bifrontal subcortical white matter on MRI can indicate various conditions such as small vessel ischemic disease, demyelination, or inflammation. Further evaluation and clinical correlation are necessary to determine the underlying cause.

What does chronic microangiopathic ischemic changes mean?
Chronic microangiopathic ischemic changes are areas of the brain that show up during radiology, usually MRIs, that depict clotted off or ruptured blood vessels. These are usually related to other serious conditions, such as diabetes, hypertension, and high cholesterol.
What is scattered punctate hyperintensities?
Scattered punctate hyperintensities are small areas of increased signal intensity seen on MRI scans. They are often non-specific findings and can be caused by various conditions such as chronic small vessel ischemic disease, demyelination, or small areas of brain injury. Additional clinical information and correlation with other imaging findings are usually needed to determine the significance of these hyperintensities.
What can cause nonspecific foci of T2 prolongation of the subcortical and periventricular white matter?
Nonspecific foci of T2 prolongation in subcortical and periventricular white matter can be caused by a variety of conditions such as small vessel ischemic disease, chronic microvascular changes, demyelination, or inflammatory processes. It is commonly seen in conditions like small vessel disease, migraine, or chronic microvascular changes related to aging. Further evaluation may be needed to determine the exact cause in each individual case.

What is chronic microvascular ischemic gliosis?
Chronic microvascular ischemic gliosis refers to a condition characterized by the degeneration of glial cells due to chronic reduced blood flow (ischemia) in the brain's microvasculature. This can lead to inflammation and the formation of scar tissue, impacting brain function and potentially contributing to cognitive decline or neurological symptoms. It is often associated with aging and conditions such as hypertension or diabetes, which affect vascular health. Diagnosis typically involves neuroimaging and clinical evaluation.
What does demyelination mean?
Demyelination refers to the loss or damage of the myelin sheath, a protective covering that surrounds nerve fibers in the central and peripheral nervous systems. This process disrupts the efficient transmission of electrical signals between neurons, leading to neurological symptoms and impairments. Conditions such as multiple sclerosis are characterized by demyelination, which can result in various physical and cognitive challenges.
Just what is CHR Ischemic hrt dis nos?
This abbreviation stands for Chronic Ischemic Heart Disease Not Otherwise Specified. It refers to a condition where there is reduced blood flow to the heart muscle over time, leading to a lack of oxygen and nutrients. It is a common cause of chest pain and can increase the risk of heart attack.
