Stroke

Restoring blood flow to the brain after a stroke is the most effective way of protecting cells from permanent damage. But existing treatments are only effective within a very short time window. Scientists are looking at ways of extending this period so, no matter how quickly people are seen, there are effective solutions to improve patients’ prognoses. In this study, they have examined whether nanotechnology could be used to deliver the drug Selenium, which protects cells and is depleted during a stroke, more effectively and quickly to the brain.

There’s a huge amount of research going on into the most effective way to treat acute stroke. At the moment there are two main treatments – thrombolysis and thrombectomy – but a study has examined whether both should be used or whether one alone is better and safer.

Scientists have examined how different brain cells respond to Stroke. The aim was to investigate communication between cells and their response to trauma, and use that to suggest how more targeted therapeutic approaches could be used as part of time-sensitive stroke recovery treatments.

The aim of this study is to determine the rates of post-stroke cognitive impairment and the risk factors for it, as well as looking at what might be causes with the hope of improving how it is predicted in individuals.

This report aims to explore whether the ongoing COVID-19 pandemic has caused delays in receiving possibly life-saving treatment for acute ischemic strokes. Ischemic stroke takes place when blood flow to the brain is reduced due to an obstruction in a blood vessel supplying the brain.

Research has shown that the healthy side of the brain that has not been affected by stroke can create new connections in an attempt to restore swallowing. This research explored that by applying magnetic stimulation to the healthy side of the brain to activate it and encourage it to create these new connections more quickly.
