Neuroscience lies at the intersection of a variety of different fields, including biology, psychology, philosophy and even history, and studying the workings of the brain is useful as a context for understanding many of the larger issues in medicine and society, says Ammar Dharani, a

Assistant Professor of Gerontology Andrei Irimia joins Professor George Shannon on the most recent episode of Lessons in Lifespan Health to discuss brain imaging and brain health, including his work to determine who is most at risk for Alzheimer’s disease after suffering a concussion or

A team of international researchers has found that the Tsimane indigenous people of the Bolivian Amazon experience less brain atrophy than their peers in higher-income nations. The decrease in their brain volumes with age is 70% slower than in American and European populations. Accelerated brain

Currently, more than 5 million Americans suffer from Alzheimer’s disease, and that number is expected to rise to 16 million by the year 2050, according to the Alzheimer’s Association. It’s now the sixth leading cause of death in the U.S., killing more people each year

U.S. News & World Report featured a study by Margaret Gatz, Andrei Irimia and colleagues that found very low rates of dementia in two Amazonian indigenous groups. “Something about the pre-industrial subsistence lifestyle appears to protect older Tsimane and Moseten from dementia,” said Gatz, the

As scientists around the world seek for solutions for Alzheimer’s disease, a new study reveals that two indigenous groups in the Bolivian Amazon have among the lowest rates of dementia in the world. An international team of researchers found among older Tsimane and Moseten people,

Brain changes in people with Alzheimer’s disease and in those with mild traumatic brain injuries (TBIs) have significant similarities, a new USC study shows, suggesting new ways to identify patients at high risk for Alzheimer’s. The findings appear this week in GeroScience. TBIs, which affect

Two USC Leonard Davis School faculty members won 2020 Hanson-Thorell Research Awards for their proposals to advance understanding around the demographics of the opioid epidemic and the connection between cognitive loss and mild traumatic brain injuries. Assistant Professors Jessica Y. Ho and Andrei Irimia will

Assistant Professor Andrei Irimia New research from USC Leonard Davis School Professor Andrei Irimia aims to use detailed brain scans to help determine why traumatic brain injuries (TBIs), such as concussions, can put certain patients at higher risk for Alzheimer’s disease (AD) and related dementias
