Summary
Titled "Preclinical study of mutations causing monogenic dementia: cognitive performance, MRI study of brain volume and connectivity, CSF markers," this is an observational study to investigate the presymptomatic and early stages of the development of monogenetic dementias. It invites all adult volunteers in families who have an autosomal-dominant inheritance pattern of AD or other monogenic dementias, i.e., frontotemporal dementia or prion diseases. Families where a mutation has been identified in one affected relative can enter the study. Both mutation carriers and unaffected siblings may enter the study. Confidential genetic testing is performed as part of the research study; participants can decide whether they do or do not want to know their genetic status. For those who do, genetic counseling and, if desired, genetic testing are available free of charge. Starting in November 2008, this study plans follow-up visits in three years. Assessments at the clinic take two days but can be scheduled over three or four half days upon request.
