Testing between intervals: A key to retaining information in long-term memory

Young children who struggle to control their emotions and behavior have more symptoms of anxiety and depression as teenagers, a study says.

People with better cognitive health are at lower risk of later Alzheimer's disease, but genetics can interfere with this, according to a new study.

Food is medicine (FIM) programs that incorporate healthy food into health care for people with or at high risk for chronic disease show great potential in improving diet quality and food security, but additional research is needed to understand clinical outcomes, according to a systematic review of randomized controlled trials in the U.S. conducted by the American Heart Association.

Cancer researchers have a multitude of tools to study tumors. Histological staining uses dyes to make different kinds of tissue cells visible in microscopic slide images. CT scans can pinpoint the size, location and spread of a tumor. Epigenetic analysis can track a cancer's growth and genetic regulation.

The disruption of axons—the thread-like part of nerve cells that transmits electrical signals—is associated with Alzheimer's disease. One way axonal function may be hindered is through damage to the myelin sheath, a fatty coating that wraps around axons. Similar to the plastic or rubber used to insulate a cable, the myelin sheath allows neurons to quickly communicate with one another. When the structure is impaired, so is the conduction of electrical signals.

A study led in part by Mount Sinai researchers has found a compelling link between the composition of the gut microbiome and the risk of cognitive impairment (RCI) in adults, underscoring the complex role that both biology and social determinants—such as food insecurity—play in brain health.

University of Alberta researchers have created a new tool to help doctors and patients recognize other illnesses commonly associated with inflammatory bowel disease (IBD), including autoimmune, mental health and heart problems.

Every three seconds, someone in the world develops dementia. Alzheimer's disease is the most common form of dementia, accounting for between 60% and 70% of all cases.

The story of the AIDS movement is one of regular people: students, bartenders, stay-at-home mothers, teachers, retired lawyers, immigrants, Catholic nuns, newly out gay men who had just arrived in New York, and many others. Some had lost friends or lovers. Some felt a moral calling. Some were just trying to balance their sexual karma. Many were angry. Most had no medical background or professional credentials—just a sense of urgency, tenacity and an unwillingness to look away.

A first-of-its-kind clinical trial found that ketamine's benefits for treating severe depression can be improved when combined with psychotherapy and supportive treatment environments.

A new lipid-based pathway essential for memory formation has been discovered by University of Queensland researchers—a breakthrough that could lead to treatments for post-traumatic stress disorder (PTSD).

A new national study reveals that most Medicaid-enrolled children with autism spectrum disorder (ASD) or intellectual disability (ID) are not receiving recommended genetic testing despite clinical guidelines urging its use. The study appears in the journal Genetics in Medicine.

Macquarie University researchers have discovered a naturally occurring protein found in human cells plays a powerful role in repairing damaged DNA—the molecule that carries the genetic instructions for building and maintaining living things.

A new lateral-flow test could one day save lives across the world through early detection of a deadly fungal disease that dramatically spiked during the COVID-19 pandemic.

By weaving oral health into primary care education, research, and community practice, recent studies demonstrate that prevention-driven, patient-centered care is imperative for a healthy population.

If you've got a dodgy tummy, diarrhea and have been vomiting, it's easy to blame a "tummy bug" or "off food."

Most treatments for Parkinson's disease (PD) only slow disease progression. Early intervention for the neurological disease that worsens over time is therefore critical to optimize care, but that requires early diagnosis. Current tests, like clinical rating scales and neural imaging, can be subjective and costly. Now, researchers in Analytical Chemistry report the initial development of a system that inexpensively screens for PD from the odors in a person's earwax.

One of the nation's largest food companies is planning a big change to its ingredients list.
