Objective: To report the rare but distinct clinical and neuropathological phenotype of non-familial, rapidly progressive parkinsonism and dementia associated with frontotemporal lobar degeneration with motor neuron disease (FTLD-MND). Methods: Subjects included two 70-year-old women presenting with rapidly progressive severe postural instability, axial-predominant parkinsonism, oculomotor dysfunction and frontal-predominant dementia with language impairment and pseudobulbar palsy. One had diffuse weakness without signs of lower motor neuron disease. Post-mortem evaluations included immunohistochemistry with antiphospho-TAR DNA-binding protein 43 (TDP-43) and genetic analysis of the TARDBP and PGRN genes. Results: Subjects died within 14 months from symptom onset. TDP-43-positive neuronal intracytoplasmic inclusions were prominent in the primary motor cortex, granule cell layer of the hippocampus, and several cranial and spinal cord nuclei. TDP-43 globular glial inclusions (GGI) were identified in one case. There were no mutations in PGRN or TARDBP genes. Conclusions: FTLD-MND due to TDP-43-proteinopathy should be considered in patients with rapidly progressive parkinsonism and dementia phenotype, especially when aphasia and/or weakness are also present.
