The cerebrospinal fluid(CSF)and blood show<unk> 5 antibodies in almost all patients -additional findings may be Oligoclonal bands(OCB), a few leukocytes and a slight rise in proteins, with otherwise normal CSF examination in more than half the cases. If tau, p-tau or beta-amyloid are found then they indicate the neuropathology of the disorder, thereby distinguishing it from other autoimmune encephalitis. Brain Imaging MRI scans of the brain show brain stem atrophy in half the cases and changes in brain regions having tau-pathy in one fifths, FDG Positron emission scans-(FDG - PET)show hyper-metabolism in region of tau-pathy in half the cases correlating well with the clinical features.
