The Dominantly Inherited Alzheimer Network is an international research effort focused on dominantly inherited Alzheimer’s disease.

Dominantly Inherited Alzheimer’s disease (DIAD) is a rare form of Alzheimer’s that causes memory loss and dementia in individuals — typically while they are in their 30s to 50s. The disease affects less than 1% of the total population of people with Alzheimer’s. The aim of the Dominantly Inherited Alzheimer Network (DIAN) is to find solutions to treat or prevent this disease and, potentially, all forms of Alzheimer’s.

DIAN’s efforts, led by Washington University School of Medicine in St. Louis, consist of a long-term observational study as well as basic science studies and clinical trials. The work is conducted in multiple countries around the world and involves researchers, clinicians, genetic counselors, individuals and families, all of whom can connect with each other via the DIAN Expanded Registry and/or through participating research sites for clinical trials or an observational study. Opportunities to participate in international family conferences and webinars also are available.

The Dominantly Inherited Alzheimer Network Trials Unit (DIAN-TU)

DIAN-TU logoThe DIAN-TU, the clinical research arm of DIAN, is an international partnership dedicated to designing and managing interventional therapeutic trials for individuals with and at risk of DIAD.

The DIAN-TU’s primary goal  is to implement effective, safe and efficient clinical trials that have the highest likelihood of success in advancing overall treatments as well as scientific understanding of inherited Alzheimer’s disease. In addition, research within the DIAN-TU is likely to advance broader understanding of all types Alzheimer’s disease with regards to causes, early detection/diagnosis, the effects of multiple classes of drugs and the impact of treating Alzheimer’s disease early.
