Study confirms neurofilament light is a useful blood-based biomarker for frontotemporal dementia, PSP, and primary progressive aphasia.
Study identified five different neurological disorders that attack the brain's language network, resulting in primary progressive aphasia.
Scene selective cortical regions are more sensitive to age than face-selective regions when it comes to memory and perception.
Language difficulties associated with primary progressive aphasia differ depending on a person's native language, a new study reports. Native English speakers with PPA have more trouble pronouncing words, while those who speak Italian had fewer pronunciation problems but tend to produce shorter and grammatically simpler sentences.
A new brain mapping study allows for individual predictions of the progression of frontotemporal dementia.
Combining neuroimaging and a constructed virtual reality town, researchers found the brain uses three different systems to perceive environment. One system allows us to recognize a place, another helps navigate through that location, and the third helps navigate from one place to another. The parahippocampal place area (PPA) helps encode location recognition, while the retrosplenial complex allows for mentally mapping the locations of specific places.
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.
Eating processed food which contains Propionic Acid (PPA) during pregnancy may affect neural stem cell development in the fetal brain. Excessive PPA reduces the number of neurons and over-produces glial cells, causing inflammation. Additionally, PPA shortens neural pathways. The combination of damaged pathways and reduced neurons may be associated with behavioral deficits associated with ASD.
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.

··5 min readMEG neuroimaging implicates the occipital place area (OPA) in our ability to rapidly sense our surroundings. The findings may advance improving machine learning and robotics technology aimed at mimicking visual processes in the human brain.
A small, preliminary study helps researchers identify a region of the brain that specializes in the processing of auditory words.
A new study reveals the brain may reassign tasks to different regions of the brain in order to counter the onset of neurodegenerative diseases.
