Subject demographics. Demographics for each case used for immunohistochemical analysis are shown. PMI = post mortem interval (hours between death and tissue harvest); C9orf72 = presence or absence of C9orf72 hexanucleotide repeat expansion; sALS = sporadic (i.e., non-familial) ALS; AD = Alzheimer’s disease, Braak stage VI; FTLD-TDP = frontotemporal lobar degeneration with TDP-43 proteinopathy
