When it comes to certain parts of the brain, bigger doesn’t necessarily equate to better memory. According to a new study led by Michigan State University, a larger hippocampus, a curved, seahorse-shaped structure embedded deep in the brain, does not always reliably predict learning and memory abilities in older adults.
A team of physicists from McMaster University has developed a process to modify red blood cells so they can be used to distribute drugs throughout the body, which could specifically target infections or treat catastrophic diseases such as cancer or Alzheimer’s.

Researchers report that accumulating amyloid protein occurred faster among persons deemed to have “objectively-defined subtle cognitive difficulties” (Obj-SCD) than among persons considered to be “cognitively normal,” offering a potential new early biomarker for Alzheimer’s disease.
The scientific community has long believed that beta-amyloid, a protein that can clump together and form sticky plaques in the brain, is the first sign of Alzheimer’s disease. Beta-amyloid then leads to other brain changes including neurodegeneration and eventually to thinking and memory problems. But a new study challenges that theory. The study suggests that subtle thinking and memory differences may come before, or happen alongside, the development of amyloid plaques that can be detected in the brain. The study is published in the December 30, 2019, online issue of Neurology®, the medical journal of the American Academy of Neurology.
A large study that followed more than one million women for nearly two decades has found that obesity in midlife is linked to a greater risk of dementia later in life; however, poor diet and lack of exercise are not. The study is published in the December 18, 2019, online issue of Neurology®, the medical journal of the American Academy of Neurology.
UCLA Health experts weigh in on the most significant healthcare advances of the last ten years and what exciting developments we can look forward to in the decade ahead.
In the search for an Alzheimer’s cure, the scientific community has focused on drugs to lessen the buildup of amyloid protein in the brain. But new research published today in Science Translational Medicine finds that targeting tau pathology shows promise.The discovery came by looking at what could make worms resistant to pathological tau protein. That’s when researchers discovered the role of the MSUT2 gene. The latest study applied to mice as well. And held true in autopsy samples of Alzheimer's patients.

For more than 14 years, Bea Weiser, 98, has volunteered at the front desk of FAU’s Louis and Anne Green Memory and Wellness Center to help attendees who are struggling with Alzheimer’s disease and other related dementias. Nothing slows down this vibrant and energetic senior who continues to maintain her independence (she still drives) and who has worked since she was 14 years old. Even a recent setback with a broken shoulder and a cancer diagnosis has not deterred her from returning to the center three afternoons a week to continue her passion to help others.

Nearly half of Americans in their 50s and early 60s think they’re likely to develop dementia as they grow older, but only 5% of them have actually talked with a doctor about what they could do to reduce their risk, a new study finds. Meanwhile, a third or more say they’re trying to stave off dementia by taking supplements or doing crossword puzzles – despite the lack of proof that such tactics work.

Columbia neuroengineers have found the first evidence that individual neurons in the human brain target specific memories during recall. They studied recordings in neurosurgical patients who had electrodes implanted in their brains and examined how the patients’ brain signals corresponded to their behavior while performing a virtual-reality object–location memory task. The researchers identified “memory-trace cells” whose activity was spatially tuned to the location where subjects remembered encountering specific objects.
