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.

Brain imaging study reveals distinct subtypes of ADHD in children

Attention-deficit/hyperactivity disorder (ADHD) is often talked about as if it were a single condition. But anyone who works with children with ADHD-or raises one-knows that symptoms can look very different from one child to another.

Enhancing myelination may help sustain therapeutic effects of psychedelic-assisted PTSD treatment

Post-traumatic stress disorder (PTSD) is not only characterized by strongly encoded traumatic memories, but also by disrupted coordination across brain networks.

New study examines blood clot risks for female astronauts in microgravity

Just a few days in simulated microgravity can subtly change the way women's blood clots, sparking bigger questions about health monitoring protocols for astronauts who can spend six months or more in orbit, say Simon Fraser University researchers.

Protein linked to Parkinson's may drive faster Alzheimer's disease progression in women

Alzheimer's-related brain changes progressed up to 20 times faster in women who also had abnormal levels of a Parkinson's-related protein, according to a Mayo Clinic study published in JAMA Network Open.

Study uncovers a biological cause for persistent taste loss after COVID-19

Some individuals have experienced a loss of taste long after a COVID-19 infection has subsided. Researchers from the Swedish University of Agricultural Sciences, Uppsala University and the University of Colorado have now shown that this may be due to a disruption in taste cells that would otherwise give rise to experiences of sweet, bitter or umami.

Canadian wildfire pollution associated with increased stroke severity

Short-term surges in air pollution in New Jersey from the 2023 Canadian wildfires were associated with a higher stroke rate and more serious strokes, according to a preliminary study released March 3, 2026, that will be presented at the American Academy of Neurology's 78th Annual Meeting taking place April 18-22, 2026, in Chicago and online.

Sucrose reduces pain in newborns during hospital needle procedures

A new Cochrane review has found that sucrose can help with pain relief in newborn babies during common hospital procedures, such as venepuncture. This involves drawing blood with a needle, typically for testing.

New blood biomarker may detect Alzheimer’s pathology more accurately

Researchers compared total plasma pTau217 with a brain-derived pTau217 assay to determine which better identifies Alzheimer’s disease–related amyloid and tau pathology. Brain-derived pTau217 showed strong diagnostic performance and appeared less affected by kidney dysfunction, supporting its potential as a more specific blood biomarker for Alzheimer’s disease.

New study explores family concerns regarding youth virtual reality use

A new study of what families think about virtual reality (VR) technologies reveals that parents want more research-based information on how VR technologies may influence brain and behavioral development. Families also placed a higher value on VR features that increase physical activity, compared to features such as educational content.
