Post-mortem neuropathological analysis confirmed multiple proteinopathies: FTLD-TDP43 (subtype A), Lewy body disease (limbic type, Braak stage 5), argyrophilic grain disease (AGD), aging-related tau astrogliopathy (ARTAG), and primary age-related tauopathy (PART). Here, TARDBP is linked to argyrophilic grain disease.
