About this study

The research study is testing a new treatment for vascular dementia (VaD) and Alzheimer’s disease with cerebrovascular disease. The new treatment is called sailuotong (SLT). SLT is an extract of three standardised Chinese herbs, ginseng, ginkgo and saffron, all of which are individually permitted for over-the-counter sale in Australia.

The primary objective is to determine the effectiveness of the herbal intervention on cognitive function (the brain functions relating to attention, memory, judgement, reasoning and problem-solving), activities of daily living and quality of life, and monitor the safety and effectiveness of SLT.

Anticipated enrolment close date: Ongoing
