Researchers have identified the location of dysfunctional brain networks that lead to impaired sentence production and word-finding in primary progressive aphasia (PPA). PPA can occur in those with neurodegenerative diseases, such as frontotemporal dementia and Alzheimer's disease. Mapping the networks allows clinicians to apply non-invasive brain stimulation to potentially improve speech in those with PPA.
fMRI brain scans reveal semantic tuning during both reading and listening to words are highly correlated in selective areas of the cerebral cortex. The new brain maps enabled researchers to accurately predict which words would active specific regions of the cortex.
Using MEG neuroimaging, researchers identify abnormalities in functional activity in brain regions which look structurally normal on conventional MRI scans. The findings could help with early detection of primary progressive aphasia.
A small, preliminary study helps researchers identify a region of the brain that specializes in the processing of auditory words.
Problems with counterfactive interpretation in those with aphasia are associated with a reduction of propositional, lexical and syntactic cognition.
A new study reveals language is learned in brain systems that predate humans.
Researchers report neurodegeneration associated with frontotemporal dementia could span from a reduced trophic support for neurons.
Researchers report that, following a stroke, mapping the brain's white matter connections in addition to imaging tissue damage could help to predict which patients will have language deficits and how severe they may be.
A new study reports the structure of the right side of the brain might help to predict who will recover from aphasia following a stroke.
Researchers discover amyloid accumulation is greater on the left side of the brain with many individuals living with PPA.
Researchers report tDCS could prove beneficial for stroke patients with chronic aphasia.
