Athletic mom's undiagnosed condition led to 2 strokes

Kelly Naab was waiting in a drive-thru lane with her two young boys in the back seat when her body suddenly felt strange. Her face began drooping. She couldn't move her right arm or speak.

Exosomes promote remarkable recovery in stroke

It's been almost a quarter century since the first drug was approved for stroke. But what's even more striking is that only a single drug remains approved today.

It's taking too long to treat rural Aussies who have a stroke

Addressing inequity between metropolitan and regional acute stroke care requires attention to each component of regional workflow, according to the authors of a Perspective published in the Medical Journal of Australia.

After stroke, an 'astounding' risk of heart problems

Women and men have a much higher risk of dangerous heart problems soon after their first stroke compared to people without stroke, even if they don't have obvious underlying heart disease, a study has found.

Tea drinkers live longer

Drinking tea at least three times a week is linked with a longer and healthier life, according to a study published today in the European Journal of Preventive Cardiology, a journal of the European Society of Cardiology (ESC).

Harnessing the microbiome to improve stroke recovery

Supplementing the body's short chain fatty acids can improve stroke recovery, according to research in mice recently published in JNeurosci. Short chain fatty acid supplementation may be a non-invasive addition to stroke ...

Stroke

A stroke is the rapidly developing loss of brain function(s) due to disturbance in the blood supply to the brain. This can be due to ischemia (lack of blood supply) caused by thrombosis or embolism or due to a hemorrhage. As a result, the affected area of the brain is unable to function, leading to inability to move one or more limbs on one side of the body, inability to understand or formulate speech, or inability to see one side of the visual field. In the past, stroke was referred to as cerebrovascular accident or CVA, but the term "stroke" is now preferred.[citation needed]

A stroke is a medical emergency and can cause permanent neurological damage, complications, and death. It is the leading cause of adult disability in the United States and Europe. In the UK, it is the second most common cause of death, the first being heart attacks and third being cancer. It is the number two cause of death worldwide and may soon become the leading cause of death worldwide. Risk factors for stroke include advanced age, hypertension (high blood pressure), previous stroke or transient ischemic attack (TIA), diabetes, high cholesterol, cigarette smoking and atrial fibrillation. High blood pressure is the most important modifiable risk factor of stroke.

The traditional definition of stroke, devised by the World Health Organization in the 1970s, is a "neurological deficit of cerebrovascular cause that persists beyond 24 hours or is interrupted by death within 24 hours". This definition was supposed to reflect the reversibility of tissue damage and was devised for the purpose, with the time frame of 24 hours being chosen arbitrarily. The 24-hour limit divides stroke from transient ischemic attack, which is a related syndrome of stroke symptoms that resolve completely within 24 hours. With the availability of treatments that, when given early, can reduce stroke severity, many now prefer alternative concepts, such as brain attack and acute ischemic cerebrovascular syndrome (modeled after heart attack and acute coronary syndrome respectively), that reflect the urgency of stroke symptoms and the need to act swiftly.

A stroke is occasionally treated with thrombolysis ("clot buster"), but usually with supportive care (speech and language therapy, physiotherapy and occupational therapy) in a "stroke unit" and secondary prevention with antiplatelet drugs (aspirin and often dipyridamole), blood pressure control, statins, and in selected patients with carotid endarterectomy and anticoagulation.
