The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Why new Alzheimer’s drugs are dividing regulators worldwide

The Lancet World Report examines why regulators in the US, UK, and Europe have reached different decisions on new amyloid-targeting Alzheimer’s drugs despite evidence that they can modestly slow clinical decline. It highlights the unresolved balance among benefits, safety risks, costs, access, and the need for broader, earlier, and more patient-centered treatment strategies.

New PET imaging approach may enable early CTE diagnosis

A first-in-class PET imaging approach can accurately detect a biomarker for chronic traumatic encephalopathy (CTE), a devastating neurodegenerative disease associated with repeated head impact.

Fruit fly study links dopamine to stress-induced sexual dysfunction

Scientists from Tokyo Metropolitan University have revealed key parts of the biochemical pathways connecting stress to sexual dysfunction.

Implanted collagen tiles double survival for brain metastasis patients

A multicenter clinical trial led by researchers at The University of Texas MD Anderson Cancer Center has found that implanting collagen tiles during brain surgery to deliver targeted radiation therapy dramatically improved tumor control, lowered the risk of recurrence and improved overall survival compared to current standard of care for patients with newly diagnosed brain metastases in need of surgical resection.

Researchers uncover new clues about the origin of Alzheimer's tau tangles

Researchers at Columbia University have uncovered new clues about the earliest molecular events that may trigger Alzheimer's disease, shedding light on how toxic tau filaments begin to form in the brain.

Gladstone scientists track exact routes used to clear brain waste

Think of the brain as if it were a house. Insulated from its environment, a house relies on complex networks-pipes, drains, and disposal systems-that interface with the outside world to keep the home functional on the inside.

New protocol screens clinical research participants for prior radiation exposure

A new study highlights a critical gap: most clinical research studies that use imaging techniques such as amyloid positron emission tomography (PET) scans do not account for the radiation participants have already received from prior medical procedures.

Grant funds research into molecular memories behind exaggerated fear

Experiencing a traumatic event sometimes produces long-lasting biological changes that can lead to an exaggerated fear response to future stressful events, such as what occurs in individuals with post-traumatic stress disorder (PTSD).

Survey reveals critical knowledge gaps in maternal health recommendations

Most Americans know that how well a mother takes care of herself before and during pregnancy affects the health of a baby, but many people remain unclear about some specific maternal health recommendations, including when to start avoiding alcohol, according to a new nationally representative survey from the Annenberg Public Policy Center (APPC) of the University of Pennsylvania.

Unhealthy snacks drive disruptive behavior in young children

Researchers at the University of Agder (UiA) have already identified clear links between what children eat and their mental health as early as the age of four.

Study reveals right ventricle better tolerates oxygen loss during cardiac arrest

A study led by scientists at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) provides new insights into ventricular fibrillation (VF), the most dangerous type of cardiac arrhythmia.

Urine-based autism screening using gut microbial metabolites

Elevated gut microbe metabolites may distinguish children with autism, paving the way for a non-invasive urine test and a new ASD subtype linked to microbiome.

The growing role of NIR-II imaging in preclinical research

NIR-II imaging has many advantages for preclinincal research as it supports deeper visualization with lower scattering and autofluorescence.

Menopause misinformation and dismissive healthcare impact women’s daily lives

Experts have exposed a gap between the surge of menopause information available online and the quality of medical care women receive, suggesting women's symptoms are too often minimised or dismissed by doctors.

Advanced tau imaging improves early Alzheimer’s disease detection accuracy

A new brain imaging test can detect a key hallmark of Alzheimer's disease before symptoms appear and earlier than the method currently used in clinical practice in the United States and Europe, report University of Pittsburgh School of Medicine researchers today in The Lancet.

UCLA researchers identify brain circuit controlling memory organization

When a person has a new experience, their brain faces a subtle but critical decision: should this experience be categorized with other stored memories, or should it be filed away as its own new memory? Getting it right allows the brain to help people navigate the world.

Blood biomarkers may detect Alzheimer’s risk before symptoms appear

For the first time, researchers found blood biomarkers for Alzheimer's disease that correlated with minor cognitive differences in midlife adults who did not have dementia.

Mental health challenges linked to hidden online harms among youth

A new study from researchers at the Child Mind Institute finds that negative online experiences are common among children and adolescents with mental health and neurodevelopmental conditions, and that most incidents are not reported through platform reporting tools.

AI maps how brain fluids move to clear waste

MR-AIV uses physics-informed AI and DCE-MRI scans to infer 3D brain-wide fluid movement in mice without direct flow measurements. The method distinguished slow diffusion-dominated transport from faster advective flow and estimated pressure and permeability patterns linked to brain waste clearance.
