Older adults with a higher ability to process sensations, including vision, olfaction, hearing, and touch, had half the risk of being diagnosed with cognitive decline than their peers who were less capable at sensory processing tasks. Read More

Dropping the level of the IL-33 immune molecule increased the number of synapses in the brain. In older mice, ramping up IL-33 helped push the number of new synapses toward a more youthful state. Read More
Circadian rhythm disruptions in older men have been linked to an increased risk of developing Parkinson's disease. The findings suggest circadian disruptions may reflect the neurodegenerative processes already affecting the brain's internal clock prior to the diagnosis of Parkinson's. Circadian disruptions, researchers say, could be considered an early warning sign of Parkinson's. Read More
Study reveals specific brain wave patterns that underlie the ability to remove irrelevant learned associations to make way for new, updated information. The research shows a particular behavior can be dependent on the synchronization of high-frequency brain waves in different parts of the brain. Read More
Study reveals a self-corrective mechanism within synapses that is activated by neurodegeneration and slows disease progression in animal models of ALS. Read More
The misconception that young people are more immune to COVID-19 is dangerous, and ignoring social distancing measures means the virus is more likely to spread among the young. Read More
Study shows how hippocampal cells can represent different hypothetical scenarios consistently and systematically over time. The findings shed new light on how place cells assist in decision making and imagination. Read More
Hailed by many as a breakthrough for neuroscience research, a new study reports brain-in-a-dish models may not be as useful as reported previously. The study reports instead of differentiating normally into the brain's distinctive cell types, cerebral organoids often express mixed genes normally found in different kinds of cells. Read More
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.

Those with a genetic predisposition to frontotemporal dementia (FTD) can become resilient to the neurodegenerative disease by remaining physically and mentally active. Read More
Researchers detected immunological remnants of enterovirus in the nervous systems of more than 12 patients with acute flaccid myelitis (AFM). The findings provide the strongest evidence to date that AFM is caused by a virus. The discovery could lead to improved diagnostics for the condition and the development of a vaccine for AFM.

A new brain mapping study allows for individual predictions of the progression of frontotemporal dementia. Read More
