Data from Brain Health Registry show utility of online unsupervised cognitive testing using the Cogstate Brief Battery in older adults

August 10, 2018

  As life expectancies around the world increase, our brains become more susceptible to age-related disorders such as Alzheimer’s disease (AD), and the earliest symptoms can be subtle. The research efforts for therapies that slow or prevent AD involve large clinical trials that require participants who have the disease but who are experiencing only very […]

Trial Design of PCSK9-inhibitor, Evolocumab, in Pediatric Patients with Heterozygous Familial Hypercholesterolemia

June 18, 2018

In this video, Prof Paul Maruff discusses a recently published paper which details the design of a study investigating the PCSK9-inhibitor, evolocumab, in pediatric patients with heterozygous familial hypercholesterolemia.
