Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

Abstract of paper from the Joint BMLA and Lasercare Meeting 2005. In the UK 800,000 people suffer from Alzheimer's disease, a figure that is expected to double before 2050. Unlike other dementias, Alzheimer's is not simply an effect of ageing, but a disease that accounts for 65% of existing dementias suffered. Currently there is no diagnostic test for Alzheimer's disease. Patients showing symptoms must undergo rigorous physical, psychiatric and neurological examinations (upon which experienced clinicians can only be 90% positive) before diagnosis is attempted; conclusive proof only ensues at post-mortem. The presence of two structural markers, senile plaques and neurofibrillary tangles, are identified at this stage. The disease causes the break down of β-amyloid and tau proteins, destroying neurons. The remaining protein fragments form clumps observed as plaques and tangles.
