Stroke

A laser-led device that shoots light into the brain to test blood flow and volume can offer instant feedback on a patient's stroke risk and and provide a portable, affordable and non-invasive way for clinicians to make life-saving interventions.

If someone has suffered a stroke, the sooner they get the appropriate medical attention, the better. A new smartphone tool may help ensure that happens, by allowing first responders to determine if a patient has indeed experienced a stroke.

Extreme night-time temperatures significantly increase the risk of stroke, according to a new study. The researchers behind the study say that armed with these findings, people can better safeguard themselves against increasingly hot nights.

The first drug to prevent heart attack and stroke cell damage is now one step closer to reality, after the K’gari funnel-web spider venom molecule Hi1a got a green light from independent safety studies, and more is learnt about its unique efficacy.

When a person has suffered a stroke, the severity of that stroke has to be determined as fast as possible. A new brain-wave-reading cap was created with that fact in mind, as it allows strokes to be assessed before the patient reaches the hospital.

A high resting heart rate, considered anything above 100 beats per minute, has been linked to an elevated risk of serious cardiovascular conditions such as coronary artery disease and stroke. Knowing how genes impact this is vital for preventative care.

While fans of Another Brick in the Wall (Part 1) may be horrified, researchers have recreated the song from brain activity. In the process, they discovered the way brains process rhythm and melody, which has huge implications for therapies.

Researchers have identified a new molecular pathway that stimulates injured brain cells to repair themselves after an ischemic stroke. The discovery may help limit or reverse the damage caused by the condition and promote recovery.

Sleep apnea affects around 30 million Americans, but it can be incredibly difficult to treat, even more so given that devices used to alleviate it are given up on by nearly half of those diagnosed. Scientists are now proposing a different approach.

When you think exercise, holding your body still in a pose for a minute hardly springs to mind as a workout. But scientists have found that isometric moves such as wall sits and planks may be even better for your heart than both weights and cardio.

We know a diet rich in fruit and vegetables has broad health benefits. Now, a new study says that prescribing free fruit and veg to adults with type 2 diabetes could prevent 296,000 cardiovascular disease cases and save billions in health-care spending.

We could soon be checking our heart rhythm while grocery shopping, thanks to a device incorporated into the handle of a supermarket cart designed to monitor for atrial fibrillation, a common heart arrhythmia that’s a key risk factor for stroke.

High levels of a common genetic ‘bad’ cholesterol protein has again turned up in the blood of coronary heart disease (CHD) patients. While one in five of us have this gene variant that can sneakily spike cholesterol levels, medical help is on the way.

Currently, if someone doesn't receive treatment within a few hours of suffering a stroke, their chances of recovery are greatly diminished. That may one day no longer be the case, however, thanks to newly developed nasal drops.

Surgeons have successfully performed a first-of-its-kind procedure in utero to treat a potentially fatal genetic defect in the brain. Usually treated after birth, the new procedure could give newborns a better chance of a normal life.
