研究问题
Frontotemporal lobar degeneration with tauopathy (FTLD-tau) typically manifests as either behavioral variant frontotemporal dementia (bvFTD) or primary progressive aphasia (PPA).
方法
We examined 47 autopsy-confirmed FTLD-tau cases from the Northwestern Alzheimer's Disease Research Center Brain Bank using postmortem digital pathology analysis to quantify tau phosphorylation and HLA-DR immunoreactivity in the amygdala.;In a subset of 19 PiD cases (10 bvFTD-PiD, 9 PPA-PiD), we assessed neuropsychiatric symptoms, tracked longitudinally using the Neuropsychiatric Inventory-Questionnaire (NPI-Q), and quantified neuronal and Pick body densities via unbiased stereology and neuronal sizes via digital pathology analysis.;Across the FTLD-tau cohort, bvFTD exhibited greater amygdalar neuroinflammation than PPA, despite comparable tau burden.
核心结论
FTLD-tau preferentially targets frontal and anterior temporal lobes, including the amygdala, contributing to severe neuropsychiatric symptoms.;This study investigated whether bvFTD and PPA due to FTLD-tau exhibit distinct amygdalar histopathology and whether these patterns reflect their initially distinct clinical phenotypes, particularly in PiD.;In a subset of 19 PiD cases (10 bvFTD-PiD, 9 PPA-PiD), we assessed neuropsychiatric symptoms, tracked longitudinally using the Neuropsychiatric Inventory-Questionnaire (NPI-Q), and quantified neuronal and Pick body densities via unbiased stereology and neuronal sizes via digital pathology analysis. ‖ 结论:These findings underscore the potential role of neuroinflammation in shaping clinical phenotypes in FTLD and highlight the role of the amygdala in complex clinicopathologic relationships.

本文属人体研究证据,但需注意:观察性或小样本干预的结论不等于已证实临床获益;效应量与长期安全性仍需更大规模、更长随访的试验验证。
