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.

Older adults with atrial cardiopathy may have higher dementia risk

Older adults with atrial cardiopathy (a major, often undetected cardiac cause of stroke) may be at increased risk of developing dementia, according to new research led by Johns Hopkins Medicine.

Specific factors may affect physical and mental quality of life among people with multiple sclerosis

Quality of life is a measure of a person's level of comfort, health and happiness. For people with multiple sclerosis (MS), a new study has found there are specific factors that may affect a person's physical and mental quality of life.

Leisure activities may help lower the risk of dementia

Leisure activities, such as reading a book, doing yoga and spending time with family and friends, may help lower the risk of dementia, according to a new meta-analysis published in the August 10, 2022, online issue of Neurology, the medical journal of the American Academy of Neurology.

Blood-based biomarkers can accurately predict a patient's risk of death or disability after TBI

A study funded by the National Institutes of Health found that biomarkers present in the blood on the day of a traumatic brain injury (TBI) can accurately predict a patient's risk of death or severe disability six months later.

Abnormal size or functioning in the heart's left atrium may increase dementia risk

Structural or functional abnormalities within the heart's left atrium, with or without symptoms, may increase a person's risk of developing dementia later in life by 35%, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.

Formulary restrictions may increase the risk of stroke in patients with atrial fibrillation

Atrial fibrillation (AF) is a major risk factor for stroke, and for decades the anticoagulant warfarin was the standard treatment for lowering that hazard. However, numerous drug and food interactions make warfarin burdensome for patients.

Neuronal cilia are important for dopamine receptor 1 signaling, study shows

A historically overlooked rod-like projection present on nearly every cell type in the human body may finally be getting its scientific due: A new study has found that these appendages, called cilia, on neurons in the brain have a key role in ensuring a specific dopamine receptor's signals are properly received.

Does loneliness affect the brain and heart?

Scientists review studies to determine the effects of social isolation and loneliness on brain health and cardiovascular conditions.

Brain-robot interfaces may help the brain reroute motor pathways damaged during stroke

Brain-robot interfaces - apparatuses where brain activity controls the movements of a robotic device that supports a hand or limb - show promise in rehabilitating paralyzed stroke patients.

Fatigue and headache among the most common symptoms following COVID-19 infections

Fatigue and headache were the most common symptoms reported by individuals an average of more than four months out from having COVID-19, investigators report.

Wrist-wearable devices more cost-effective than electrocardiograms and pulse palpation for atrial fibrillation screening

Screening individuals for atrial fibrillation (AF) using wearable devices is more cost-effective than screening using conventional methods such as 12-lead electrocardiogram (ECG) and pulse palpation, or than no screening at all, researchers from Massachusetts General Hospital (MGH) have found.

Optically controlled local heat-pulse method manipulates temperature in cells

A team of researchers led by Osaka University finds that mutant variants of the calcium channel protein RyR1 are hypersensitive to heat, which creates a positive feedback loop of calcium release and leads to malignant hyperthermia

French study on cardiovascular disease incidence during COVID pandemic and vaccination campaign

Researchers describe failures of the French healthcare system as reflected by increased hospitalizations due to certain acute cardiovascular diseases in 2021.

Digital support tool helps reduce alcohol intake

A digital support tool on your phone can help if you want to reduce your alcohol consumption. This has been shown in a study by researchers at Linköping University. They have developed and evaluated a digital tool which helps individuals reduce their alcohol intake on their own.

Children are less fit and more obese than ever before, study says

Record levels of obesity and physical inactivity among children mean they are set to bear the brunt of poorer health effects from rising global temperatures – that's the stark warning in a new comprehensive review of current studies on the topic.

Heart failure arises from mutations in distinct genes, study finds

Heart failure is a common and devastating disorder for which there is no cure. Many cardiomyopathies - conditions that make it difficult for the heart to pump blood such as dilated cardiomyopathy (DCM) and arrhythmogenic cardiomyopathy (ACM) - can lead to heart failure, but treatments for patients with heart failure do not take these distinct conditions into account.

Higher suPAR levels linked with increased risk of blood clot formation

Blood clots are thought to occur in as many as a third of patients hospitalized with COVID-19. In many cases these clots can be deadly, such as pulmonary embolisms - blood clots that travel to the lungs. In fact, in nearly one third of patients with COVID-19, these clots led to death.

‘Children are not little adults’ and need special protection during heat waves

After more than a week of record-breaking temperatures across much of the country, public health experts are cautioning that children are more susceptible to heat illness than adults are — even more so when they're on the athletic field, living without air conditioning, or waiting in a parked car.
