Wernicke encephalopathy (WE), also Wernicke's encephalopathy, [1] or wet brain is the presence of neurological symptoms caused by biochemical lesions of the central nervous system after exhaustion of B-vitamin reserves, in particular thiamine (vitamin B 1). [2]
A concern about this illness is that it mimics multiple sclerosis when looking at the vision loss and brain lesions. If close attention is not paid to the retina of a patient with vision loss and brain lesions, their symptoms may be mistaken for MS instead of Susac's syndrome. This may account for the low prevalence of the illness.
Solitary sclerosis: This variant was proposed (2012) by Mayo Clinic researchers. [58] though it was also reported by other groups more or less at the same time. [59] [60] It is defined as isolated demyelinating lesions which produce a progressive myelopathy similar to primary progressive MS.
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)
Sometimes the diagnosis must be retrospective, relying on gradual worsening of neurological signs/symptoms, due to the lack of understanding of the pathogenicity driving disease progression. [1] However, the only definite diagnosis of MS is post-mortem autopsy, where lesions typical of MS can be detected through histopathological techniques.
The latter effect may be due to either protective effects of fever, or that diagnosis and treatment is sought more rapidly when fever is present. [68] ADEM can progress to MS. It will be considered MS if some lesions appear in different times and brain areas [69]
Brain abscess (or cerebral abscess) is an abscess within the brain tissue caused by inflammation and collection of infected material coming from local (ear infection, dental abscess, infection of paranasal sinuses, infection of the mastoid air cells of the temporal bone, epidural abscess) or remote (lung, heart, kidney etc.) infectious sources.
This confirms the absence of neuronal function in the whole brain. Patients classified as brain dead are legally dead and can qualify as organ donors, in which their organs are surgically removed and prepared for a particular recipient. [citation needed] Brain death is one of the deciding factors when pronouncing a trauma patient as dead.
