Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
PML is diagnosed in a patient with a progressive course of the disease, finding JC virus DNA in spinal fluid together with consistent white-matter lesions on brain magnetic resonance imaging (MRI); alternatively, a brain biopsy is diagnostic [1] when the typical histopathology of demyelination, bizarre astrocytes, and enlarged oligodendroglial ...
Green tea drinkers have fewer brain lesions linked to dementia. Katharine Lang. January 16, 2025 at 6:00 AM. Green tea could help preserve brain health as we age, a new study shows.
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)
The people with lower levels also had more lesions in the white matter in their brains, which can be a warning sign of cognitive decline, dementia or stroke, the researchers found. The findings ...
He explains that common reasons people have seizures include strokes, brain tumors, brain lesions, and infections such as meningitis. "About a quarter of patients suffering from seizures are born ...
It was not until the 1980s that attention turned to the usually co-existing organic brain lesions originally thought to be essentially unrelated or coincidental. Today, the Capgras syndrome is understood as a neurological disorder, in which the delusion primarily results from organic brain lesions or degeneration.
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]
