Measurement of CSF oligoclonal bands [102,103] or the glial-associated molecules TREM2 and progranulin [64] did not reveal any differences in LBD groups, whereas another study did find elevated soluble TREM2 (sTREM2) levels (blood and CSF) in the DLB group compared to controls [67]. Here, TREM2 is linked to Lewy body dementia.
