Predicting functional recovery after stroke

Clinical prediction of a patient’s recovery is an important medical aim for stroke survivors.

A team including researchers from King’s College London developed and checked (validated) a tool that seems to accurately predict how well or poorly a patient will recover after their stroke. The team used data from the South London Stroke Register  to develop and check the tool. The tool could help clinicians to work out the likely recovery of a patient based on various factors such as their age, sex, level of disability and stroke subtype. They could use this information to provide more personalised care for patients.

The report on this study is published in the International Journal of Stroke as ‘Patient-specific prediction of functional recovery after stroke’. It was written by

Air pollution research and stroke

Long-term exposure to high levels of outdoor air pollution has been linked with poor health in many cities around the world.

Using information from the South London Stroke Register (SLSR), a team including researchers from King’s College London wanted to find out if people who had a stroke were affected by higher levels of outdoor air pollution. They looked at the health of 1800 people who had a stroke between 2005-2012.

The researchers found that those living in areas with lower levels of particulate matter live longer after a stroke. Particulate matter is a type of air pollutant made up of tiny bits of matter floating in the air from natural sources such as dust and pollen as well as man-made sources like soot, smoke and car exhausts.

SLSR researchers and air pollution scientists from King’s College London are doing more research to find out how particulate matter causes poor health effects in people.

Results from the South London Ethnicity and Stroke Study

Stroke incidence (the number of people who have a stroke) is higher in people with black ethnic backgrounds but the reasons for this are not well understood. The South London Ethnicity and Stroke Study (SLESS) has tried to better understand why people of black ethnicity are at higher risk of stroke by exploring patterns in the different types of stroke and in the underlying risk factors. The journal article on the final results from the study are available in the BMC Medicine journal here.

The study recruited 2400 patients (black Caribbean, black African and white ethnic groups) from an area of South London and analysed information on the subtype of stroke that they had had (e.g. small vessel stroke or cardioembolic stroke) and the risk factors that they had had before the stroke (e.g. high blood pressure). They found that black patients and white patients do not have the same chance of having each subtype of stroke.
