Heterogeneous ribonuclear protein E2 (hnRNP E2) is associated with TDP-43-immunoreactive neurites in Semantic Dementia but not with other TDP-43 pathological subtypes of Frontotemporal Lobar Degeneration.
 

Author(s): Yvonne S Davidson, Andrew C Robinson, Louis Flood, Sara Rollinson, Bridget C Benson, Yasmine T Asi, Anna Richardson, Matthew Jones, Julie S Snowden, Stuart Pickering-Brown, Tammaryn Lashley, David M A Mann

Journal:

 

Frontotemporal Lobar Degeneration (FTLD) encompasses certain related neurodegenerative disorders which alter personality and cognition. Heterogeneous ribonuclear proteins (hnRNPs) maintain RNA metabolism and changes in their function may underpin the pathogenesis of FTLD. Immunostaining ...

Semantic word category processing in semantic dementia and posterior cortical atrophy.
 

Author(s): Zubaida Shebani, Karalyn Patterson, Peter J Nestor, Lara Z Diaz-de-Grenu, Kate Dawson, Friedemann Pulvermüller

Journal: Cortex. 2017 08;93():92-106.

 

There is general agreement that perisylvian language cortex plays a major role in lexical and semantic processing; but the contribution of additional, more widespread, brain areas in the processing of different semantic word categories remains controversial. We investigated word processing ...

Evidence of semantic processing impairments in behavioural variant frontotemporal dementia and Parkinson's disease.
 

Author(s): Katheryn A Q Cousins, Murray Grossman

Journal: Curr. Opin. Neurol.. 2017 Dec;30(6):617-622.

 

Category-specific impairments caused by brain damage can provide important insights into how semantic concepts are organized in the brain. Recent research has demonstrated that disease to sensory and motor cortices can impair perceptual feature knowledge important to the representation ...

Journal:

 

Progressive and relatively circumscribed loss of semantic knowledge, referred to as semantic dementia (SD) which falls under the broader umbrella of frontotemporal dementia, was officially identified as a clinical syndrome less than 50 years ago. Here, we review recent neuroimaging, ...
