Type A is characterized by abundant TDP-43-immunoreactive compact neuronal cytoplasmic inclusions and short dystrophic neurites, often with neuronal intranuclear inclusions (A); type B by abundant compact and granular cytoplasmic inclusions (B); type C by abundant long dystrophic neurites (C); and type D by abundant lentiform neuronal intranuclear inclusions and many short dystrophic neurites (D).
