Study Reveals Trade-off Between Complex Words and Complex Grammar in Sentences

People with primary progressive aphasia who have difficulty producing complex words as a result of their condition, compensate by stringing together a sequence of simpler words to convey the idea they wish to express.

Speech-disrupting brain disease reflects patients’ native tongue

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.

Navigating ‘Neuralville’: Virtual town helps map brain functions

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.

Map of broken brain networks shows why people lose speech in language-based dementia

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.

Processed foods may hold key to rise in autism

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.

Detecting dementia’s damaging effects before it’s too late

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.
