Brain lesions are sometimes intentionally inflicted during neurosurgery, such as the carefully placed brain lesion used to treat epilepsy and other brain disorders. These lesions are induced by excision or by electric shocks (electrolytic lesions) to the exposed brain or commonly by infusion of excitotoxins to specific areas.
In 1949, the idea that WE lesions are a result of a disruption to the blood-brain barrier was introduced. [53] Large proteins passing into the brain can put neurological tissue at risk of toxic effects. The blood-brain barrier junctions are typically found to have WE lesions located at that region of the brain. [53]
Microinfarcts are microscopic lesions, of cellular death or tissue necrosis, which are a result of pathologies involving small vessels. Such pathologies are arteriosclerosis or cerebral amyloid angiopathy. [5] Microinfarcts take longer to affect neuronal death progress, at up to 28 days, rather than hours. [6]
According to DIPG.org, DIPG "is a type of brain tumor found in the brainstem" that affects children between 5 and 7 years old. In the GoFundMe page set up for Jules, ... Since her death, Joe's ...
Brain ischemia is a condition in which there is insufficient bloodflow to the brain to meet metabolic demand. [1] This leads to poor oxygen supply or cerebral hypoxia and thus leads to the death of brain tissue or cerebral infarction/ischemic stroke. [2] It is a sub-type of stroke along with subarachnoid hemorrhage and intracerebral hemorrhage. [3]
Diffuse axonal injury after a motorcycle accident. MRI after 3 days: on T1-weighted images the injury is barely visible. On the FLAIR, DWI and T2*-weighted images a small bleed is identifiable. DAI is difficult to detect since it does not show up well on CT scans or with other macroscopic imaging techniques, though it shows up microscopically. [9]
Lesions can be extra-axial, (occurring within the skull but outside of the brain) or intra-axial (occurring within the brain tissue). [24] Damage from TBI can be focal or diffuse , confined to specific areas or distributed in a more general manner, respectively; [ 25 ] however, it is common for both types of injury to exist in a given case.
Normally MS lesions are small ovoid lesions, less than 2 cm. long, oriented perpendicular to the long axis of the brain's ventricles [18] Often they are disposed surrounding a vein [19] Demyelinization by MS. The Klüver-Barrera colored tissue show a clear decoloration in the area of the lesion (Original scale 1:100)
