Numerous studies conducted in recent years have suggested that most dementia—including cases correctly diagnosed as Alzheimer’s disease—probably traces not to a particular lesion type but to combinations of brain pathologies. A new study, said by its authors to be the largest and most comprehensive look at such data, strengthens the suspicion.

Open science and information sharing on a medical specialty-wide scale are the cornerstones of community-based research efforts in disciplines such as neuroimaging, according to Cameron Craddock, PhD, of the Nathan S. Kline Institute for Psychiatric Research.

African-Americans are more likely to develop dementia and Alzheimer’s disease than other ethnicities, while Asian-Americans have the lowest risk of developing dementia among U.S. ethnic groups, according to results of a study published online in Alzheimer’s & Dementia.

Scientists are beginning to unlock some of the secrets of a rare type of language dementia known as primary progressive aphasia using amyloid PET imaging.

A new concussion assessment tool could improve doctors’ ability to determine whether pediatric patients will experience persistent post-concussive symptoms (PPCS), according to results of a new study published online March 8 in JAMA.

Elekta, the Stokholm, Sweden-based supplier of radiation oncology and neurosurgery systems, announced today that its Leksell Gamma Knife Icon stereotactic radiosurgery system (SRS) was used to treat a patient in the United States for the first time.

It’s one of those research stories in which the story is as good as the research. It involves cutting-edge fMRI, a neuroscientist struggling to use it to directly associate blood responses with neural signals, and a student who aspired to work in the scientist’s lab and had just the rare condition for the job (of calculating the connections, that is).

March is Brain Injury Awareness Month, an effort undertaken by The Brain Injury Association of America (BIAA), which has worked to provide help to those dealing with the life-altering affects of brain injuries for more than 35 years.
