El anuncio se produce después de que varias demandas alegaran que cientos de pasajeros sufrieron lesiones cerebrales en X2, una atracción con asientos que giran 360 grados.
(MedPage Today) -- Local control after surgical removal of large brain metastases improved significantly when patients received fractionated stereotactic radiosurgery (SRS) instead of single-fraction SRS, a randomized trial showed. Surgical-bed...
(MedPage Today) -- The New York Times looked at what alcohol does to the brain and what amount, if any, may be safe. Ongoing phase I/II studies of ifezuntirgene inilparvovec (AMT-130) in Huntington's disease showed continued slowing of disease...
Neurocirugía carmenfernandez Congresos El tratamiento quirúrgico de la hemorragia intracerebral es ahora menos invasivo, especialmente mediante técnicas endovasculares y endoscópicas , y gracias a ello, más seguro y efectivo, ha explicado a este diario Jesús Lafuente , neurocirujano del Hospital del Mar y el Hospital…
A new study in mice led by Washington University in St. Louis researchers suggests that stopping certain immune cells from entering the brain could limit neurodegeneration.
Las variaciones hormonales, la respuesta al estrés y el metabolismo cerebral ayudan a explicar una brecha que la longevidad femenina no logra justificar por sí sola
Administrar radioterapia focalizada en tres a cinco sesiones después de la cirugía para una metástasis cerebral grande logra reducir el riesgo de que el cáncer reaparezca en el sitio quirúrgico en comparación con administrar la radiación en una sola sesión, según los resultados del estudio…

La esclerosis múltiple (EM) es una enfermedad crónica del sistema nervioso central que afecta principalmente a adultos jóvenes. Además de síntomas físicos, la EM impacta de forma significativa en la salud mental y la calidad de vida. En Chile existe escasa información sobre estos…
Los seres humanos y el lenguaje mantienen una relación única. Ninguna otra especie posee capacidades lingüísticas tan complejas como las nuestras, y el cerebro humano es especialmente sensible a las características del habla. Pero existe un antiguo interrogante: ¿procesamos el habla con tanta eficiencia porque…
A new study suggests coffee may influence mood and brain function by changing the activity of microbes in the gut. Both caffeinated and decaf coffee were linked to lower stress, depression, and impulsivity, while also producing measurable changes in gut bacteria and metabolites. Decaf was…
Strengthening the body’s natural daily rhythms helped mice recover after stroke by improving the brain’s waste-clearing system and reducing lingering inflammation. The approach worked even when treatment began three days after the stroke, suggesting circadian-based therapies could eventually offer a new way to support long-term…
Scientists found that immune cells contributing to Alzheimer’s-related brain damage may be activated in lymph nodes outside the brain before traveling into the nervous system. Blocking this pathway in mice dramatically reduced neurodegeneration and preserved cognitive abilities, pointing to a potentially more accessible treatment target.
A large health-record analysis found that glucosamine use was associated with a 25% higher likelihood of mild cognitive impairment progressing to dementia. Lab experiments suggest the popular joint supplement may intensify an abnormal sugar-tagging process in the Alzheimer’s brain, although researchers say clinical trials are…

Un equipo de la Universidad Médica de Wrocław, en Polonia, halló que las dificultades para conciliar el sueño, los despertares frecuentes y la somnolencia diurna se asociaron con más días de cefalea al mes y menor bienestar
Diversos estudios científicos identificaron el impacto de esta vía nerviosa, que conecta el cerebro con el corazón, los pulmones y el sistema digestivo, con resultados que varían según la modalidad, el dispositivo y el perfil de cada paciente
Los expertos tratan de conocer qué áreas del cerebro actúan en la pérdida de la conciencia.
Los científicos investigan estos episodios en personas con Alzheimer y trastornos relacionados, aunque aún desconocen los mecanismos cerebrales que hacen posible el retorno temporal de capacidades cognitivas aparentemente perdidas
A large study tracking more than 95,000 people suggests that how you sleep may be linked to your risk of developing dozens of diseases. People who spent more time in REM sleep had lower risks of 83 conditions, including dementia, heart failure, and Parkinson’s disease…
Cellular mechanisms in early Alzheimers disease (AD) remain poorly understood despite generation of extensive observational multiomic data. Weighted integration across diverse datasets can prioritise convergent mechanisms and targets. We conducted a systematic review to identify datasets profiling cell-type-specific changes in early AD. We integrated multiomic…
Researchers have found evidence that long COVID may damage dopamine releasing neurons in the brain, potentially explaining persistent fatigue, low motivation, slowed movement, and memory difficulties. The discovery could lead to new treatments that target the brain's dopamine system.
Stem cell transplants helped regenerate stroke-damaged brain tissue in mice, producing new neurons and restoring lost motor function. The treatment also improved blood vessels, inflammation, and the blood-brain barrier, raising hopes that a similar approach could eventually help repair the human brain after stroke.
Alzheimer disease is defined by the accumulation of extracellular amyloid-β plaques and intraneuronal neurofibrillary tangles composed of hyperphosphorylated tau. For many years, drug development efforts have focused on amyloid-β plaques, culminating in the recent approval of the amyloid-targeting monoclonal antibodies lecanemab and donanemab for the…
This randomized clinical trial examines the efficacy and safety of the potent oral O-linked N-acetylglucosaminidase inhibitor ceperognastat in early symptomatic Alzheimer disease.
This study evaluated whether the oral O-linked N-acetylglucosaminidase inhibitor ceperognastat, at doses of 0.75 and 3 mg, compared with placebo, slows clinical progression in patients with early symptomatic Alzheimer disease with low to medium tau levels.
A new needle-thin brain implant can record neural activity, deliver drugs, and stimulate multiple brain regions using a single flexible fiber. Successful tests in mice suggest it could give scientists a more precise, less invasive way to study the brain and may eventually help treat…
Scientists have found that the human brain develops from two distinct cellular systems, suggesting that evolution fused together two ancient nervous systems with very different jobs. The discovery also allowed researchers to grow human hindbrain neurons in the lab, opening new possibilities for studying ALS…
La especialista en neuropsicología clínica Camila Sánchez Salinas acaba de publicar Entrená tu cerebro , con pautas bien concretas para prevenir o frenar el deterioro leve o incipiente. Hacé el test interactivo al final de la nota.
Newer blood thinners may do more than prevent strokes in people with Alzheimer’s disease and atrial fibrillation. Researchers found that patients taking NOACs experienced a slower decline in cognitive function than those using warfarin or no blood thinners. The effect was modest each year but…
Scientists found that declining levels of the brain protein Menin may help drive aging, with lower levels in mice linked to inflammation, cognitive decline, weaker bones, and thinner skin. Restoring Menin reversed several age-related changes, while the amino acid D-serine improved cognition, hinting at a…
Scientists discovered that brain-cell axons may not be smooth tubes as textbooks have shown for more than a century, but instead naturally resemble strings of tiny pearls. Those pearl-like structures can change with neural activity and may help control how quickly electrical signals travel through…
Scientists discovered a hidden “immune organ” inside the skull that acts as a rapid first responder against brain cancer in mice. Strengthening this local immune defense improved tumor rejection and survival, raising the possibility of new treatments that target the skull directly.
Scientists have uncovered sweeping changes in how the human brain controls and organizes its genome beginning in midlife, offering new clues to why aging sharply increases the risk of Alzheimer’s and other neurodegenerative diseases. One of the biggest shifts occurred between about ages 50 and…
