Parenchymal Volume Loss, also known as Parenchymal Atrophy, signifies the reduction in the volume of a specific organ or tissue. This condition can affect various organs, with lungs, brains, kidneys and livers being common examples.
People with brain atrophy, also called cerebral atrophy, lose brain cells (neurons), and connections between their brain cells and brain volume often decreases. This loss can lead to problems with thinking, memory and performing everyday tasks.
Brain parenchymal atrophy, in simple terms, refers to the loss of brain tissue volume. It’s a process that can occur naturally as we age, but when accelerated or exacerbated by various factors, it can lead to devastating consequences.
Cerebral atrophy is the morphological presentation of brain parenchymal volume loss that is frequently seen on cross-sectional imaging. Rather than being a primary diagnosis, it is the common endpoint for a range of disease processes that affect the central nervous system.
“Mild global cerebral atrophy” or “mild cortical atrophy” or “atrophy commensurate with age” As we age, our brains gradually shrink after approximately age 35, initially averaging at a rate of about 0.5% of total volume loss per year, and accelerating into old age (1).
Brain parenchyma is divided into two main components: gray matter and white matter. 1. Gray Matter. Gray matter is the darker tissue in the brain and is primarily composed of nerve cell bodies and dendrites. It plays a crucial role in processing information, decision-making, and memory storage.
What is Brain MRI commonly used for? Doctors use this exam to help diagnose the cause of neurologic symptoms, such as headache, dizziness, weakness, changes in sensation, memory loss, confusion, and seizures.
White matter disease is an umbrella term for damage to your brain’s white matter caused by reduced blood flow to the tissue. It can cause issues with memory, balance and mobility. People who have risk factors for cardiovascular disease also have a greater risk of developing white matter disease. What is white matter disease?
Pathological loss of brain parenchyma due to neurodegeneration, i.e. brain atrophy, is an important aspect of many diseases affecting the central nervous system (CNS), such as multiple sclerosis, [1] dementia [2] and Huntington’s disease [3].
Renal parenchymal disease is a group of conditions that can develop in the parenchyma of your kidneys. The parenchyma is the functional part of an organ, as opposed to the parts that give the...
