Cerebral atrophy is a common feature of many of the diseases that affect the brain. [1] Atrophy of any tissue means a decrement in the size of the cell, which can be due to progressive loss of cytoplasmic proteins. In brain tissue, atrophy describes a loss of neurons and the connections between them.
These changes are most prominent in the kidney and can lead to ischemia and acute kidney failure. In the brain, a small cavity called a lacune is an ischemic cavity that can arise due to brain necrosis, due to arteriolosclerosis. [15] [16] Cause. It can be caused by chronic benign (essential) hypertension [17] malignant hypertension. [4] [18]
The cerebral atrophy that alcoholics often present with is due to alcohol induced neurotoxicity. [7] [11] Evidence of neurodegeneration can be supported by an increased microglia density and expression of proinflammatory cytokines in the brain. Animal studies find that heavy and regular binge drinking causes neurodegeneration in corticolimbic ...
Classically, DDS arises in individuals starting hemodialysis due to end-stage chronic kidney disease and is associated, in particular, with "aggressive" (high solute removal) dialysis. [3] However, it may also arise in fast onset, i.e. acute kidney failure in certain conditions.
According to the prevailing amyloid hypothesis of Alzheimer's disease, the aggregation of amyloid-beta (a peptide normally produced in and cleared from the healthy young brain) into extracellular plaques drives the neuronal loss and brain atrophy that is the hallmark of Alzheimer's dementia.
Small vessel diseases (SVDs) affect primarily organs that receive significant portions of cardiac output such as the brain, the kidney, and the retina. Thus, SVDs are a major etiologic cause in debilitating conditions such as renal failure , blindness , lacunar infarcts , and dementia .
Subdural hygromas require two conditions in order to occur. First, there must be a separation in the layers of the Meninges of the brain. Second, the resulting subdural space that occurs from the separation of layers must remain uncompressed in order for CSF to accumulate in the subdural space, resulting in the hygroma. [1]
Kidney ischemia [1] is a disease with a high morbidity and mortality rate. [2] Blood vessels shrink and undergo apoptosis which results in poor blood flow in the kidneys. More complications happen when failure of the kidney functions result in toxicity in various parts of the body which may cause septic shock, hypovolemia, and a need for surgery. [3]
