Code-switching in multilinguals with dementia: patterns across speech contexts.

Code-switching in multilinguals with dementia: patterns across speech contexts. Clin Linguist Phon. 2019 Apr 24;:1-22 Authors: Svennevig J, Hansen P, Simonsen HG, Landmark AMD Abstract The study investigates code-switching by multilingual persons with dementia in two different speech contexts, picture naming tests and spontaneous conversation. It combines a psycholinguistic perspective on cognitive and linguistic skills with a qualitative conversation analytic approach to understanding the functions and appropriateness of code-switching in social interaction. The analysis shows that code-switching is used as a resource for compensating for word-retrieval problems in both the naming tests and in word search sequences in conversation. Furthermore, it serves to demarcate meta-communicative parentheses in which the participants comment on their process of word retrieval or express frustration about processing problems. Code-switching is generally treated as appropriate and relevant by the participants. In most instances, the speakers switch to a language known by the interlocutor. Only a few instances are treated as inappropriate by not being understandable to the interlocutor or by not adapting to the established language of the conversation. The patterns of code-switching are discussed considering typical symptoms of cognitive decline associated with dementia. Only very few instances may be interpreted as caused by a lack of awareness of the interlocutor's...

We present here the development of an electrochemical immunosensor based on nanostructured screen-printed carbon electrodes for the quantification of unfolded p53 in plasma samples. The sensor shows a suitable linear range (from 2 to 50 nM) for its application in real blood samples and a very low limit of detection (0.05 nM). The concentration of unfolded p53 has been accurately detected in plasma of elderly people in healthy conditions, subjects with mild cognitive impairment (MCI) and Alzheimer's Disease (AD) subjects, obtaining results with no significant differences to those provided by an ELISA assay. These result...

In 2016, UC San Francisco researchers discovered mice with an Alzheimer's risk gene had fewer 'sharp-wave ripples.' Their new study suggests these memory waves can predict dementia 30 years early.

SteinAbstractWe performed a randomized, double blind, placebo-controlled trial with blueberry supplementation in older adults with mild cognitive impairment. We measured cognitive performance and parent (unmodified food form) anthocyanins and a suite of flavonoid-based phase 2 metabolites arising from anthocyanins in urine. The blueberry-treated group exhibited improved semantic access (p = 0.01) and visual-spatial memory ...
