​Neurocognitive impairments are classified by pathological changes with potential for destruction of neural tissue. One change known to occur in neurodegenerative disorders is an accumulation of proteins causing pathological damage.

Increased risk for anxiety may begin before birth, shaped by infection or stressful events during pregnancy, according to a new preclinical study from researchers at Weill Cornell Medicine.

The university stage, particularly its beginning, is a time of tension and emotional stress for young students-many of whom are under the age of 20.

A new University of South Florida study published in Menopause highlights a largely overlooked health issue: voice changes that many women experience during menopause, often triggered by falling levels of estrogen and progesterone.

In a three-year study involving more than 5,000 residents of Israel before and after the mass traumatic events of October 7, 2023, those who watched extensive media coverage of the attacks were found to be more likely to develop post-traumatic stress disorder (PTSD).

Implementing artificial intelligence (AI) into NHS hospitals is far harder than initially anticipated, with complications around governance, contracts, data collection, harmonisation with old IT systems, finding the right AI tools and staff training, finds a major new UK study led by UCL researchers.

Experts caution that nanoplastics and microplastics may constitute an emerging cardiovascular risk factor, with particles identified in arterial plaques associated with a 4.5-fold increase in major adverse cardiovascular events. Experimental evidence points to inflammation, oxidative stress, and vascular injury as key mechanisms.

New research from the University of Sydney's Charles Perkins Centre has found that genes play an active role in shaping the bacteria found in our gut, questioning the idea that gut health is influenced only by diet.

New research from the University of Minnesota Medical School is providing important insights into how COVID-19 persists in cancer patients even long after testing positive. The findings were recently published in iScience.

Researchers measured airborne microplastics and chemical additives in a Portuguese school near an industrial complex. They found higher levels indoors than outdoors, with children continuously exposed to a complex mix of pollutants.

People with chronic insomnia may experience faster declines in memory and thinking skills as they age-along with brain changes that can be seen on imaging scans-than people who do not have chronic insomnia, according to a study published in the September 10, 2025, issue of Neurology, the medical journal of the American Academy of Neurology.

Green tea is an ancient beverage recognized for its medicinal and antioxidant properties. It has been widely studied for its beneficial effects on metabolic diseases, such as obesity and type 2 diabetes.

Tumors are stressful places for cancer-fighting immune cells. Low oxygen, high acid levels, and other stressors put strain on mitochondria, the cell's energy factories, leading to T cell exhaustion and poor cancer outcomes.

Mitochondria act as energy factories in cells and have their own, separate DNA. Mutations to mitochondrial DNA (mtDNA) have been observed in cancer, but it has been unclear how these changes might affect cancer growth.

Death rates from chronic diseases have fallen in four out of five countries around the world in the last decade - but progress has slowed, suggests an analysis led by researchers at Imperial College London and published in The Lancet.

Existing approaches to parent-focused behavioral programs delivered up to 12 months of age which aim to combat childhood obesity are insufficient to improve body mass index (BMI) at approximately two years of age, according to the largest study to date on the topic published in The Lancet.

Spinal cord injuries caused by external trauma, such as traffic accidents or falls, often lead to the permanent loss of motor and sensory functions.

Research led by Liverpool School of Tropical Medicine and the Malawi-Liverpool-Wellcome Programme shows that over half of hospital patients with breathlessness had died within a year of admission (51%), as opposed to just 26% of those without the symptom.

Researchers found that THC, the psychoactive compound in cannabis, alters oocyte gene expression, spindle formation, and chromosome segregation, lowering embryo euploidy rates in IVF. This provides direct human evidence linking cannabis exposure to impaired female fertility outcomes.

A large U.S. registry study of more than 168,000 patients found that daylight saving time (DST) clock changes did not increase heart attack rates or worsen in-hospital outcomes. The findings suggest that the lost or gained hour is unlikely to trigger acute myocardial infarction in contemporary care.
