MILD COGNITIVE IMPAIRMENTMild Cognitive Impairment (MCI) is not a condition or disease, but an attempt to define the transition between normal aging and dementia. The diagnostic criteria for mci is still unstable and with undelineated boundaries. There are two categories of MCI: Amnestic and Non-amnestic. Memory is the dominant problem in Amnestic MCI and roughly 15% of those defined as such convert to Alzheimer’s disease. In Non-amnestic MCI memory problems are not as predominant, but includegeneral impairments of cognition, such as impairments in language, visuospatial awareness, and attention. Also the underlying causes of these impairments seem to be vascular, psychiatric or neurologic. These patients convert to Alzheimer’s Disease less often (2%) than Amnestic MCI.
