FTD pathology organized by clinical syndrome

(Ljubenkov and Miller, 2016)


FTD organized by underlying pathology

(Ljubenkov and Miller, 2016)

  • FTLD-tau: (MAPT)
    • 3R tau (Pick’s disease)
      • bvFTD > nfvPPA, svPPA, CBS
    • 4R tau, CBD
      • Motor dysexecutive (including CBS) > PSP-S, nfvPPA, bvFTD
    • 4R tau, PSP
      • PSP-S > CBS, nfvPPA, bvFTD
  • FTLD-TDP
    • TDP type A (GRN)
      • bvFTD > CBS, nfsvPPA > FTD-MND
    • TDP type B (C9ORF72)
      • bvFTD, FTD-MND, ALS
    • TDP type C
      • svPPA
    • TDP type D (always VCP mutation)
      • bvFTD, ALS, Paget’s disease of the bone, inclusion body myositis
  • FTLD-FUS (FUS gene)
    • atypical FTLD with ubiquitin inclusions, basophilic inclusion body disease; neuronal intermediate filament inclusion disease
      • bvFTD if sporadic (w/ early age of onset (22-46 years) versus ALS if genetic
