Abstract

 Findings of clinical,neuropathological and biochemical studies have supported the idea that frontotemporal lobar degeneration with ubiquitin inclusions (FTLD-U) and amyotrophic lateral sclerosis (ALS) are part of a neurological disease spectrum. This concept is now further strengthened by the recent discovery of a 43-kDa transactivating responsive sequence DNA-binding protein (TDP-43) as a key component of the underlying neuropathology of FTLD-U,ALS with dementia (ALS-D) and ALS. Here we describe the clinicopathological features of selected autopsy cases belonging to this disease spectrum,and discuss the neuropathological similarities and differences between FTLD-U and ALS-D,with special reference to the morphology,distribution and density of ubiquitin/TDP-43-positive abnormal structures,along with a review of the literature.
