Brain MRI is the mainstay of initial investigation pointing to limbic lobe pathology revealing increased T2 signal involving one or both temporal lobes in most cases. [ 22 ] [ 14 ] Serial MRI in LE starts as an acute disease with uni- or bilateral swollen temporomesial structures that are hyperintense on fluid attenuation inversion recovery and ...
MRI of subject with eventual autopsy-proven LATE/LATE-NC. MRI scans are used to detect structural changes in the brain. In LATE, MRI may reveal severe atrophy in the medial temporal lobe, particularly in the hippocampus and amygdala, which are key areas affected by TDP-43 pathology, and may indicate hippocampal sclerosis.
Encephalitis with meningitis is known as meningoencephalitis, while encephalitis with involvement of the spinal cord is known as encephalomyelitis. [ 2 ] The word is from Ancient Greek ἐγκέφαλος , enképhalos 'brain', [ 37 ] composed of ἐν , en , 'in' and κεφαλή , kephalé , 'head', and the medical suffix -itis 'inflammation'.
Autoimmune encephalitis (AIE) is a type of encephalitis, and one of the most common causes of noninfectious encephalitis. It can be triggered by tumors , infections , or it may be cryptogenic . The neurological manifestations can be either acute or subacute and usually develop within six weeks.
Research shows that the most common areas to have focal lesions in non-penetrating traumatic brain injury are the orbitofrontal cortex (the lower surface of the frontal lobes) and the anterior temporal lobes, areas that are involved in social behavior, emotion regulation, olfaction, and decision-making, hence the common social/emotional and ...
Herpes simplex encephalitis; Other names: Herpes encephalitis, Herpesviral encephalitis: Coronal T2-weighted MR image shows high signal in the temporal lobes including hippocampal formations and parahippogampal gyrae, insulae, and right inferior frontal gyrus. A brain biopsy was performed and the histology was consistent with encephalitis. PCR ...
Gerstmann syndrome is a neurological disorder that is characterized by a constellation of symptoms [1] that suggests the presence of a lesion usually near the junction of the temporal and parietal lobes at or near the angular gyrus. Gerstmann syndrome is typically associated with damage to the inferior parietal lobule of the dominant hemisphere ...
Anti-NMDA receptor encephalitis is a type of brain inflammation caused by antibodies. [4] Early symptoms may include fever, headache, and feeling tired. [1] [2] This is then typically followed by psychosis which presents with false beliefs (delusions) and seeing or hearing things that others do not see or hear (hallucinations). [1]
