RT Journal Article SR Electronic T1 Rapidly progressive atypical parkinsonism associated with frontotemporal lobar degeneration and motor neuron disease JF Journal of Neurology, Neurosurgery & Psychiatry JO J Neurol Neurosurg Psychiatry FD BMJ Publishing Group Ltd SP 751 OP 753 DO 10.1136/jnnp.2009.201608 VO 82 IS 7 A1 Alberto J Espay A1 Salvatore Spina A1 David J Houghton A1 Jill R Murrell A1 Gabrielle M de Courten-Myers A1 Bernardino Ghetti A1 Irene Litvan YR 2011 UL http://jnnp.bmj.com/content/82/7/751.abstract AB 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.
