Stroke News and Research

RSS

A stroke is a medical emergency. Strokes happen when blood flow to your brain stops. Within minutes, brain cells begin to die. There are two kinds of stroke. The more common kind, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. "Mini-strokes" or transient ischemic attacks (TIAs), occur when the blood supply to the brain is briefly interrupted.

New Study Proves Research Models Accurately Replicate Cancer ecDNA Loops

Damage to DNA in cancer cells can lead to pieces breaking off chromosomes and floating away, like icebergs cracking off from a glacier. Just as icebergs are a threat to ships and their crew, these scattered bits of DNA loom large to physicians and cancer patients by having titanic effects on tumor progression and treatment resistance.

Researchers Find Simple Genetic Links for Extreme Traits

Researchers at the Icahn School of Medicine at Mount Sinai have found evidence that people who fall at the extreme high or low ends of certain traits, such as cholesterol, blood glucose, height, and age at menopause, are more likely to have a simple genetic explanation than previously thought.

Analysis Reveals Blurred Neural Patterns During Failed Cognitive Switches

Most people have experienced the feeling: switching from one task to another, only to find the brain momentarily stuck in the old mode of thinking. Sometimes, even after realizing a strategy no longer works, the mind keeps returning to it anyway.

Sensory Nerve Signals Block the Immune System's Response to Lung Cancer

Researchers at the Francis Crick Institute have revealed that sensory nerve signals interfere with the immune system's response to lung cancer. This previously unrecognized neuroimmune connection could be targeted to improve responses to immunotherapy.

Researchers Compare Embryonic and Adult Mouse Brain Targets to Map Memory Networks

A peer-reviewed invited review published today in Genomic Psychiatry argues that the adult brain, when it learns and remembers and rewires, is not inventing something new.

Interactions Across the Genome Drive Neurodevelopmental Risks

People who have the same deletion of a section of chromosome 16 are susceptible to neurodevelopmental disorders; however, some may simply show moderate psychological symptoms like anxiety or depression, while others may have significant intellectual disability or developmental delay.

Scientists Discover New Rare Genetic Disease Using Whole Exome Sequencing

Scientists at Sanford Burnham Prebys Medical Discovery Institute and an international team of collaborators used a genetic sequencing technique called whole exome sequencing to discover a new rare genetic disease.

Molecular Switch AHR Limits Neuron Regeneration and Axon Repair

Researchers from the Icahn School of Medicine at Mount Sinai have discovered a molecular switch in neurons that limits the regrowth of damaged axonal fibers.

Transplanted Mitochondria Enhance Cell Metabolism and Survival Under Stress

Mitochondria, also known as the powerhouses of the cell, are essential for cell survival, repair, and adaptation.

Lab-Grown Brain Tissue Masters a Classic Computing Benchmark

Imagine balancing a ruler upright in the palm of the hand: There is a need to continually pay attention to the angle of the ruler and make several little changes to ensure it does not topple over.

Postmortem Human Retinas Recover Neural Light Signals

The ability to restore light responses in human retinas postmortem offers a novel model for studying retinal recovery and developing vision-restoring therapies.

Mitochondria Transfer Eases Chronic Nerve Pain

For millions living with nerve pain, even a light touch can feel unbearable. Scientists have long suspected that damaged nerve cells falter because their energy factories known as mitochondria don't function properly.

CRISPR Reveals Dark Genome Regions That Sense Cellular Mechanics

Researchers at Duke University used CRISPR technologies to discover previously unannotated stretches of DNA in the 'dark genome' that are responsible for controlling how cells sense and respond to the mechanical properties of their local environment.

How Singing Mice Reveal the Roots of Vocal Communication

All mice squeak, but only some sing. Scotinomys teguina, aka Alston's singing mice, hail from the cloud forests of Costa Rica. More than 2,000 miles north, Cold Spring Harbor Laboratory (CSHL) neuroscientists study these musically gifted mammals to better understand the evolutionary origins of vocal communication.

Genetic Variants Reveal Unexpected Link Between Obesity Risk and Cholesterol Levels

Individuals with a genetic profile that puts them at risk of obesity may not necessarily be at risk of having high cholesterol, UTHealth Houston researchers discovered.

Study Reveals How Blood Vessels Drive Neuron Movement in the Brain

Researchers have discovered how newly created neurons depend on blood flow in the adult brain to travel from their site of origin to their final location.

Disrupted Circadian Rhythms Alter Gene Activity in Alzheimer’s Disease

Alzheimer's disease is notorious for scrambling patients' daily rhythms. Restless nights with little sleep and increased napping during the day are early indicators of disease onset, while sundowning, or confusion later in the day, is typical for later stages of the disease.

MRI And 3D Printing Reveal How Artificial Hearts Manage Blood Flow

The integration of 4D flow MRI and 3D printing in TAH research offers vital insights into blood flow patterns, crucial for advancing heart failure therapies.

Cryo-EM Study Uncovers Hidden Steps in NMDA Receptor Activation

When it comes to brain proteins, small changes can make a dramatic difference. Researchers studying NMDA (N-methyl-D-aspartate) receptors, which are essential for learning, memory and moment-by-moment consciousness, know that even slight changes in their activity level can mean the difference between normal function and serious neurological disorders.
