DIAN - Dominantly Inherited Alzheimer Network

An international research partnership of leading scientists determined to understand a rare form of Alzheimer''''s disease that is caused by a gene mutation and to establish a research database and tissue repository to support research on Alzheimer''''s disease by other investigators around the world. Understanding of this form of Alzheimer''''s disease may provide clues to decoding other dementias and developing dementia treatments. DIAN is currently enrolling study participants who are biological adult children of a parent with a mutated gene known to cause dominantly inherited Alzheimer''''s disease. Such individuals may or may not carry the gene themselves and may or may not have disease symptoms. Research suggests that certain brain changes occur years before actual Alzheimer''''s symptoms are detected. One goal of DIAN is to study these possible changes in people who carry an Alzheimer''''s disease mutation. Other family members without a mutation will serve as a comparison group. People in families in which a mutation has been identified will be tracked in order to detect physical or mental changes that might distinguish people who inherited the mutation from those who did not. A list of procedures that participants may be involved in include: * Clinical assessment * Memory and thinking tests * Blood draw * Cerebral spinal fluid sample testing and banking * Brain magnetic resonance imaging (MRI) * Brain fluorodeoxyglucose positron emission tomography (FDG PET) * Brain positron emission tomography using Pittsburgh Compound-B (PET-PIB) * Brain autopsy in case of death Participants will have the procedures at the time of enrollment into DIAN and thereafter every one to three years, depending on the participant''''s age and the age at which his or her family member began to show signs of Alzheimer''''s disease. DIAN currently involves eleven outstanding research institutions in the United States, United Kingdom, and Australia. John C. Morris, M.D., Friedman Distinguished Professor of Neurology at Washington University School of Medicine in St. Louis, is the project''''s principal investigator.
