Q: What is tau?
Q: What is a systematic review?
Systematic reviews allow researchers to combine all the scientific evidence on one area of research and identify where the gaps in our knowledge are. This form of desk-based research is carried out by thoroughly reviewing every study on one topic, for example the link between having a stroke and developing dementia. Each study is weighted according to how well-designed it was and statistical tests are carried out to find the consensus between them.
This sort of research is essential to determine progress in a field of research and to inform the direction of research in the future.
Alzheimer's Society is currently engaged in a series of systematic reviews of all the evidence on how lifestyle factors, such as diet and exercise, are linked to the risk of developing dementia. This important Public Health work will enable our services and helpline team to give people the best advice and will help us to direct the future of these areas of research.
