Further breakdown of the blood–brain barrier, in turn cause a number of other damaging effects such as swelling, activation of macrophages, and more activation of cytokines and other destructive proteins. Astrocytes can heal partially the lesion leaving a scar. These scars (sclerae) are the known plaques or lesions usually reported in MS.
Apraxia is most often due to a lesion located in the dominant (usually left) hemisphere of the brain, typically in the frontal and parietal lobes. Lesions may be due to stroke , acquired brain injuries , or neurodegenerative diseases such as Alzheimer's disease or other dementias , Parkinson's disease , or Huntington's disease .
Brain herniation can cause severe disability or death. In fact, when herniation is visible on a CT scan , the prognosis for a meaningful recovery of neurological function is poor. [ 2 ] The patient may become paralyzed on the same side as the lesion causing the pressure, or damage to parts of the brain caused by herniation may cause paralysis ...
The cysts and cavities (cystic brain lesions) are more likely to be the result of destructive (encephaloclastic) cause, but can also be from abnormal development (malformative), direct damage, inflammation, or hemorrhage. [5] The cysts and cavities cause a wide range of physiological, physical, and neurological symptoms. [6]
The most common cause of ideomotor apraxia is a unilateral ischemic lesion to the brain, which is damage to one hemisphere of the brain due to a disruption of the blood supply, as in a stroke. There are a variety of brain areas where lesions have been correlated to ideomotor apraxia.
Asian optic-spinal MS - this variant can present brain lesions like MS. [18] Longitudinally extensive myelitis or optic neuritis associated with systemic autoimmune disease. Optic neuritis or myelitis associated with lesions in specific brain areas such as the hypothalamus , periventricular nucleus , and brainstem .
The pain you’re feeling when you get brain freeze is actually from a layer of receptor cells in the outer covering of the brain, called the meninges. This is where the internal carotid artery ...
Even a mild incident can have long-term effects or cause symptoms to appear years later. [5] Studies show there is a correlation between brain lesion and language, speech, and category-specific disorders. Wernicke's aphasia is associated with anomia, unknowingly making up words , and problems with comprehension.
