Brain scans can help estimate the time when a person will start showing signs of dementia

Researchers at Washington University School of Medicine in St. Louis have developed an approach to estimating when a person with no cognitive symptoms will start showing signs of Alzheimer's dementia based on data from brain scans and the person's age.

Newly identified mechanism can accelerate the development of STING-activating drugs using imaging

A new study from scientists at the UCLA Jonsson Comprehensive Cancer Center found that emerging drugs that activate the protein STING, a well-established regulator of immune cell activation, substantially alter the activity of metabolic pathways responsible for generating the nucleotide building blocks for DNA.

Scientists decipher missing pieces of the reward system puzzle to increase motivation

Our motivation to put effort into achieving a goal is controlled by a reward system wired in the brain. However, many neuropathological conditions impair the reward system, diminishing the will to work.

Long-term exposure to air pollutants increases the risk of dysmenorrhea in women

Dysmenorrhea, that is, frequent severe and painful cramps during menstruation from abnormal contractions of the uterus, is the most common of all gynecological disorders. It affects between 16-91% of girls and women of reproductive age, of whom 2%-29% have symptoms severe enough to restrict their daily activity.

New PET imaging method tracks immunotherapeutic efficacy in mouse models

Several cancer tumors grow through immunosuppression; that is, they manipulate biological systems in their microenvironments and signal to a specific set of immune cells--those that clear out aberrant cells--to stop acting. It is no wonder that immunotherapy designed to re-establish anti-tumor immunity is rapidly becoming the treatment of choice for these cancers.

APOE ɛ4 carriers with midlife depressive symptoms may be at higher risk of tau accumulation

Middle-aged people with depressive symptoms who carry a genetic variation called apolipoprotein (APOE) ε4 may be more at risk to develop tau protein accumulations in the brain's emotion- and memory-controlling regions, a new study by researchers from The University of Texas Health Science Center at San Antonio and collaborating institutions suggests.

FDA grants accelerated approval for first-of-its-kind Alzheimer's treatment

Today, the U.S. Food and Drug Administration approved Aduhelm (aducanumab) for the treatment of Alzheimer's, a debilitating disease affecting 6.2 million Americans. Aduhelm was approved using the accelerated approval pathway, which can be used for a drug for a serious or life-threatening illness that provides a meaningful therapeutic advantage over existing treatments.

University of Freiburg professor honored for groundbreaking results on the brain’s immune system

The blood-brain barrier is an impenetrable barrier between the circulating blood and the brain established before birth that prevents immune cells from entering the brain from the body's immune system. Thus, the brain has its own immune system with a key actor called microglia.

Moderate alcohol intake may be heart protective by reducing stress-related brain signals

Moderate alcohol intake--defined as no more than one alcoholic drink for women and two for men per day--has been associated with a lower risk of dying from cardiovascular disease when compared with individuals who abstain from drinking or partake in excessive drinking, according to a new study being presented at the American College of Cardiology's 70th Annual Scientific Session.

$3.5 million grant awarded to address the underrepresentation of Black adults in Alzheimer's research

Black adults are more likely than other groups to develop Alzheimer's disease or related disorders but are poorly represented in Alzheimer's disease research, including recent clinical trials. This health disparity illustrates how Black individuals can benefit from advances in the field if they had access.
