Mild Cognitive Impairment: A Prospective Community Study.  aka Monongahela-Youghiogheny Healthy Aging Team is supported in part by the NIA* under research grant #AG023651 (Principal Investigator: Mary Ganguli).


The MYHAT project seeks to describe the distribution of Cognitive Impairment, No Dementia (CIND) and Mild Cognitive Impairment (MCI) and related entities, their associated features, their outcomes over time, and the predictors of these outcomes.  An age-stratified random community sample of approximately 2,100 was recruited and screened using cognitive, functional, and other health-related measures to identify the non-demented who are cognitively impaired.  Among them, we identified subgroups meeting operational criteria for MCI of amnestic and other varieties.  Participants are further classified according to multiple, potentially overlapping, schema which are in current use by different groups.  Subgroups are also characterized with regard to demographic, clinical, and biological variables which may predict outcomes and/or have diagnostic significance.  Annual follow-up assessments track changes in cognitive and functional ability and identify transitions to clinical states including Alzheimer's disease and other dementing disorders.  Analysis of these prospectively gathered data allow subgroups to be defined according to outcome, and thus permit the empirical refinement of clinical and research criteria for various forms of mild cognitive impairment.
