Cerebral softening, also known as encephalomalacia, is a localized softening of the substance of the brain, due to bleeding or inflammation. Three varieties, distinguished by their color and representing different stages of the disease progress, are known respectively as red, yellow, and white softening.
The latter hypothesis is supported by the frequent finding of diffuse blood vessel spasms (vasoconstriction) in many people with PRES, [1] and the evidence for decreased perfusion, [5] although the spasm may also be a consequence of the blood vessel damage rather than the cause. [4] Some, therefore, include the vasospasm in the "toxic" theory. [3]
On a large autopsy material without selecting the most frequently detected PVL in male children with birth weight was 1500-2500 g., dying at 6–8 days of life. Diffuse brain damage with softening (diffus leucomalacia, DFL) are found more frequently in children weighing less than 1500 g. However, PVL is not a DFL. [1]
More than 40% of people with cirrhosis develop hepatic encephalopathy. [7] More than half of those with cirrhosis and significant HE live less than a year. [1] In those who are able to get a liver transplant, the risk of death is less than 30% over the subsequent five years. [1] The condition has been described since at least 1860. [1]
A small group of individuals with CTE have chronic traumatic encephalomyopathy (CTEM), which is characterized by symptoms of motor-neuron disease and which mimics amyotrophic lateral sclerosis (ALS). Progressive muscle weakness and balance and gait problems (problems with walking) seem to be early signs of CTEM.
Two young siblings died after being swept away by a rapidly flowing creek in Southern California's San Bernardino Mountains, authorities said. The tragedy occurred Tuesday when a mother took her 4 ...
Toxic leukoencephalopathy is a rare condition that is characterized by progressive damage (-pathy) to white matter (-leuko-) in the brain (-encephalo-), particularly myelin, due to causes such as exposure to substance use, environmental toxins, or chemotherapeutic drugs.
Signs and symptoms are classified into three groups based on the affected functions of the frontal and temporal lobes: [8] These are behavioural variant frontotemporal dementia, semantic dementia, and progressive nonfluent aphasia. An overlap between symptoms can occur as the disease progresses and spreads through the brain regions.
