Coexisting adult polyglucosan body disease with frontotemporal lobar degeneration with transactivation response DNA-binding protein-43 (TDP-43)-positive neuronal inclusions.

| Abstract |
Frontotemporal lobar degeneration with ubiquitin-positive inclusions (FTLD-U) is one of the most common pathological findings associated with the clinical FTLD syndromes. However, molecular characterization with genetic sequencing and protein expression techniques are recognizing many new subtypes for FTLDs. FTLDs are diverse and new nomenclature schemes have been proposed based on the molecular defects that are being discovered ( Mackenzie et al., 2010 , Acta Neuropathologica, 119, 1). Adult polyglucosan body disease (APBD) is a very rare disorder associated with systemic neurological signs and symptoms including progressive dementia with executive dysfunction and motor neuron disease. We report the clinical course of an individual with a clinical FTLD and the as yet unreported findings of coexistent APBD with FTLD-U and transactivation response DNA-binding protein-43 (TDP-43)-positive inclusions at autopsy (or more accurately, FTLD-TDP). It is unclear if these distinct findings are coincidental in this individual, or if pathogenic pathways may intersect to promote these coexisting pathologies.
