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.

New clinical guideline adopts holistic approach to brain and heart health

A new brain–heart clinical practice guideline takes a holistic approach, integrating neurologic and mental health evidence with guidance for cardiovascular disease as many brain and heart conditions overlap and share similar risk factors.

Mount Sinai researchers identify a highly prevalent recessive neurodevelopmental disorder

Researchers at the Icahn School of Medicine at Mount Sinai in New York have identified and described a previously unknown recessive neurodevelopmental disorder (NDD) that appears to be the most prevalent ever discovered.

NOX-1 identified as key molecular target to prolong ketamine's antidepressant effects

Treatment-resistant depression affects a large proportion of people with major depressive disorder, and while ketamine offers rapid relief, its antidepressant effects fade within a few weeks.

Inside the high-stakes corporate fight over feeding preterm babies

In 2013, a scientist at Abbott Laboratories saw study results with potentially big implications for the company's profits and the lives of some of the world's most fragile people: preterm infants.

Short bursts of vigorous activity can lower risk of major diseases

People who get just a few minutes of vigorous activity daily are less likely to develop eight major diseases, including arthritis, heart disease and dementia, according to research published in the European Heart Journal today (Monday).

Parasites trigger a gut-to-brain signal that cuts food intake during infection

Researchers found that intestinal tuft cells signal to crypt enterochromaffin cells by releasing acetylcholine, triggering serotonin release and activating a gut-to-brain vagal pathway during type 2 inflammation. This sustained signalling, rather than the initial acute response, was linked to reduced food intake in mouse models of parasitic infection.

APOE4 alters brain immunity and cognition differently in females and males

APOE4 drove sex-specific changes in meningeal immunity, lymphatic drainage, brain lipids, neuroinflammation, and cognition in mouse models, with females showing greater inflammatory and cognitive vulnerability. Suppressing innate immunity improved some cognitive outcomes in female E4/E4 mice but worsened them in male E4/E4 mice, underscoring the need for sex-tailored approaches.

Catheter-based approach improves prognosis in pulmonary embolism patients

Patients who had low doses of clot-buster drugs delivered directly to the site of a pulmonary embolism (PE) via a catheter using ultrasound to enhance their effect had significantly better outcomes than those who received standard systemic anticoagulants, according to a study presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Brain resilience peaks about an hour after stress exposure

Psychological resilience is often misunderstood as simple "toughness" or an insensitivity to stress. However, true resilience is the brain's capacity to adapt and recover after a stressful event.

Perceived partner effort boosts cognitive control during cooperative tasks

A study assesses whether perceiving a partner's effort leads to greater engagement of executive control mechanisms to maintain focus on a task.

Gut immune responses found to trigger brain inflammation in MS

Multiple sclerosis (MS) is a debilitating neurological disorder caused by malfunctioning immune responses that target the brain and spinal cord of the central nervous system (CNS).

Drugs targeting TIE2 protein could help prevent formation of cerebral cavernous malformations

Researchers in the Perelman School of Medicine at the University of Pennsylvania have identified a cell surface receptor protein called TIE2 as the missing link between two key signaling pathways that drive the growth of blood vessel abnormalities known as cerebral cavernous malformations (CCMs).

Hospital delirium associated with increased likelihood of future dementia

Older adults who develop delirium during a hospital admission face a substantially higher risk of dementia in later years, even if they had no prior health conditions, according to a major new population study.

Dandelion leaves boost brain-protective compounds after digestion

Dandelion leaves are rich in polyphenols with neuroprotective effects, offering insights into natural strategies for Alzheimer's disease management.

Attachment anxiety linked to higher risk of short video addiction

No matter where we turn on social media, short videos are everywhere. Repeated exposure to this brief, information-dense, and rewarding content stimulates the brain in a way that tells us the experience is pleasurable or satisfying.

High-intensity therapy early after stroke shows no added benefit

A clinical trial led by University of Auckland researchers found that high-intensity therapy for patients begun within two weeks of a stroke did not improve hand and arm recovery beyond standard care.
