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.

Rare YKT6 Gene Variants Linked to New Neurological Disorder

A recent collaborative study has discovered rare variants in the YKT6 gene as the cause of a new neurological disorder characterized by developmental delays along with severe progressive liver disease and a potential risk for liver cancer.

New Study Sheds Light on Blood-Brain Barrier Dysfunction in Aging

The central nervous system requires a tightly controlled environment for the neurons in the brain to function properly and be able to process information. The blood-brain barrier, which is maintained by specific brain endothelial cells lining blood vessel inner walls, controls the exchange of chemicals between the neurological and circulatory systems.

Cells Harvested From Urine May Have Diagnostic Potential for Kidney Disease

Genes expressed in human cells harvested from urine are remarkably similar to those of the kidney itself, suggesting they could be an important non-invasive source of information on the kidney.

New Biomarker Offers Early Detection of ALS and FTD

Two progressively degenerative diseases, amyotrophic lateral sclerosis (ALS, commonly known as Lou Gehrig's disease) and frontotemporal dementia (FTD, recently in the news with the diagnoses of actor Bruce Willis and talk show host Wendy Williams), are linked by more than the fact that they both damage nerve cells critical to normal functioning -; the former affecting nerves in the brain and spinal cord leading to loss of movement, the latter eroding the brain regions controlling personality, behavior and language.

Gut Microbial Metabolite Linked to Increased Thrombosis Risk in COVID-19 Patients

A gut microbial metabolite called 2-methylbutyrylcarnitine (2MBC) plays a role in exacerbating thrombosis -- the formation of blood clots – researchers report February 23rd in the journal Cell Metabolism.

Researchers Unveil New Mechanism of Immune Cell Training in Thymus Gland

Immune cells must learn not to attack the body itself. A team of researchers from the Technical University of Munich (TUM) and the Ludwig Maximilian University of Munich (LMU) has discovered a previously unknown mechanism behind this: other immune cells, the B cells, contribute to the "training" of the T cells in the thymus gland.

Prefrontal Neurons’ Cascade of Phonetic Representations

A new study led by researchers at Massachusetts General Hospital (MGH) uses sophisticated brain recording techniques to show how neurons in the human brain cooperate to enable people to plan words for speech and then produce them verbally.

Exploring the Dual Role of Phosphorylated α-Synuclein in Healthy Neural Function

It has been found by researchers that phosphorylated α-synuclein, a protein linked to a number of neurodegenerative illnesses, including Parkinson's disease and Lewy body dementia, is also engaged in the regular processes of neuronal communication in a healthy brain.

New Study Sheds Light on Evolution of Sex Differences in Animals

Researchers at the Francis Crick Institute and Heidelberg University in Germany have shown that sex differences in animals vary dramatically across species, organs and developmental stages, and evolve quickly at the gene level but slowly at the cell type level.

Direct-to-Consumer Blood Test for Assessing User’s Alzheimer’s Disease Risk

In July, the first direct-to-consumer blood test designed to assess a user’s risk for developing Alzheimer’s disease hit the market. The test, which has not undergone Food and Drug Administration (FDA) review, measures the level of a protein called beta amyloid, a key component of plaques that form in the brains of Alzheimer’s disease patients, disrupting brain function.
