Knight ADRC in the News

People with Alzheimer Disease or other types of dementia often face years of memory and thinking problems that eventually require help from others to assist with daily activities. An estimated 83% of people caring for older adults in the US are family members, friends or other unpaid caregivers. People providing care may have emotional and physical stress, or financial burdens, especially when caring for someone in the later stages of the disease. In this collection of narratives, authors write about the challenges, struggles, and joys of providing care for family members or another close person with Alzheimer’s Disease.

…researchers at Washington University School of Medicine in St. Louis have found — in mice — that Alzheimer’s-like tau deposits in the brain lead to the accumulation of a form of cholesterol known as cholesteryl esters, and that lowering cholesteryl ester levels helps prevent brain damage and behavioral changes.

…Alzheimer’s researchers and clinicians aren’t convinced the Quest test is backed by sound scientific research. The possibility of false-positive results is high, as is the likelihood that older adults won’t understand the significance of their results, they say. The test should be taken only under a physician’s supervision, if at all, they advise. And, priced originally at $399 (recently discounted to $299) and not covered by insurance, it isn’t cheap.

In search of ways to prevent these destructive tau tangles, researchers at Washington University School of Medicine in St. Louis have identified a key step in their development. Intervening at this step potentially could forestall the destructive cascade of events that results in brain damage, the researchers said. The findings are published Sept. 20 in the journal Molecular Psychiatry.

The Food and Drug Administration (FDA) recently gave full approval to Leqembi (lecanemab) for patients in the early stages of Alzheimer’s disease. Barbara Joy Snider, MD, PhD, answers questions about the drug.
