Alzheimer’s disease (AD) is the most common type of dementia which is the second leading cause of death of Australians. 

Experts believe that prevention is the best intervention for Alzheimer’s disease given that current knowledge suggests that the brain changes commence 20 to 30 years before the onset of symptoms. This study aims to establish the effectiveness of a testosterone and fish oil intervention to prevent the development of AD. It is called the TotAL Study (Testosterone and Omega Three – Amyloid Lowering).

This study seeks elderly men who are concerned about their memory. Participants are required to attend up to 13 study visits at the research centre over a period of approximately 14 months. A close family member or friend is also required to accompany the participant during the initial and final study visit.
