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.

The aging American population means that more people are at risk for stroke

A leading stroke researcher says the aging of the American population means that more people are at risk for stroke, and unless new approaches are developed to reduce stroke incidence, it will surpass heart attacks and cancer as the major cause of long-term disability and premature death.

Groundbreaking new study that may help stroke patients regain greater use of their hands or arms

The trial showed that study participants – stroke survivors suffering impaired hand or arm movement – who underwent physical rehabilitation accompanied by motor cortex stimulation showed greater improvement than participants who received physical rehabilitation alone.

Discovery of the gene for a form of Joubert Syndrome

Researchers at the University of California, San Diego (UCSD) School of Medicine have discovered the gene for a form of Joubert Syndrome, a condition present before birth that affects an area of the brain controlling balance and coordination in about 1 in 10,000 individuals.

Gene variations explain why people with type 2 diabetes are at much greater risk for coronary artery disease

New studies by an international team of scientists led by Joslin Diabetes Center have found variations in a gene that help explain why people with type 2 diabetes are at much greater risk for coronary artery disease, the leading cause of death for this group.

Atypical antipsychotics commonly used to treat children with aggression, bipolar disorder, and schizophrenia may trigger insulin resistance

Researchers from the Johns Hopkins Children's Center say a group of drugs known as "atypical antipsychotics" that are commonly used to treat children with aggression, bipolar disorder, and schizophrenia may trigger insulin resistance, a condition that increases the risk of developing Type 2 diabetes and heart disease later in life.

Tamoxifen use for the treatment of breast cancer is not associated with an increased risk of stroke

Tamoxifen use for the treatment of breast cancer is not associated with an increased risk of stroke, according to a new study in the October 20 issue of the Journal of the National Cancer Institute. However, chemotherapy use is associated with an increased risk of stroke, regardless of tamoxifen use.

Long-term outcome after intravenous thrombolysis of basilar artery occlusion

Occlusion of the basilar artery (BAO) is a relatively infrequent but the most catastrophic form of ischemic stroke with a dismal natural course, carrying from 85 to almost 95 % mortality.

Lack of improvement 24 hours after stroke treatment associated with poor outcome or death at 3 months

Stroke patients who show little improvement in the first 24 hours after receiving thrombolytic (clot-dissolving) therapy are more likely to have poor outcomes or death at three months, according to a study in the October 20 JAMA.

Study identifies factors associated with higher risk of death in hospital after treatment for stroke

Stroke patients who were older and had disturbances of their consciousness had a greater risk of death in the hospital following thrombolytic (clot-dissolving) therapy, according to an article in the October 20 JAMA.

Possible link between elevated calcium levels in older neurons and aging-related disorders of the brain

Brain cells become increasingly unable to regulate calcium loads as they age, becoming more vulnerable to injury and premature death, according to new findings that Virginia Commonwealth University researchers will present at an international conference this month.

Scientists have devised a novel way to repair one of the genetic mutations that causes ataxia-telangiectasia

UCLA scientists have devised a novel way to repair one of the genetic mutations that causes ataxia-telangiectasia, (A-T), a life-shortening disorder that devastates the neurological and immune systems of one in 40,000 young children.

FDA approves partial artificial heart

The U.S Food and Drug Administration (FDA) has approved a partial artificial heart intended to keep people alive in the hospital while they are awaiting a heart transplant.

Discovery of fundamental mechanism within cells that link obesity and type 2 diabetes

Researchers from the Harvard School of Public Health have discovered what they believe is the fundamental mechanism within cells that links two fast-rising public health threats: obesity and Type 2 diabetes.

Location of body fat on older women can indicate the likelihood of heart disease

The location of body fat on older women can indicate the likelihood of heart disease, according to a new study published in The Journal of Clinical Endocrinology & Metabolism.

Single protein appears central to the formation of the long-term memories

Researchers at the National Institute of Child Health and Human Development have discovered that a single protein appears central to the formation of the long-term memories.

Research shows brain cells move like a two-stroke engine

Following the often-quoted advice of Yogi Berra — "You can observe a lot by just watching" — Rockefeller University scientists show that nerve cells in the developing brains of humans and other mammals move in a two-part "step" led by a structure within the cell called the centrosome.

Robotic microscope shows how mutant Huntington's disease protein affects neurons

Using a specially designed robotic microscope to study cultured cells, researchers have found evidence that abnormal protein clumps called inclusion bodies in neurons from people with Huntington's disease (HD) prevent cell death.

Researchers have discovered an effective new way to treat giant cell arteritis

Mayo Clinic researchers have discovered an effective new way to treat giant cell arteritis (GCA), a debilitating cause of headaches, fatigue, muscle pain and even blindness. The findings of this research will be presented at the American College of Rheumatology Annual Scientific Meeting.

Surgical treatment for morbid obesity helps prevent hyperlipidemia, hypertension, and obstructive sleep apnea

A summary of data from numerous studies suggests that the majority of morbidly obese patients who underwent bariatric (obesity) surgery experienced effective weight loss and improvement in diabetes, hyperlipidemia, hypertension, and obstructive sleep apnea, according to an article in the October 13 issue of JAMA.

Changes in reimbursement have reduced length of stay for patients receiving inpatient medical rehabilitation

Although medical rehabilitation patients are spending less time as inpatients at facilities, their functional outcomes have not declined. However, the death rate following discharge has increased nearly 4 percent from 1994 to 2001, according to a study in the October 13 issue of JAMA.
