Mild cognitive impairment
Memory impairment, verified by means of neurocognitive tests, is a core criterion in Mild Cognitive Impairment (MCI). MCI has clinically been defined as a condition characterized by memory complaints, normal activities of daily living, normal general cognitive function, abnormal memory for age and no dementia. The diagnosis of MCI requires considerable clinical judgement and comprehensive clinical assessment.
Although MCI can present with a variety of symptoms, when memory loss is the predominant symptom it is termed “amnestic MCI” and is frequently seen as an early stage of Alzheimer’s disease. Individuals with amnestic-MCI tend to progress to developing Alzheimer’s disease at a rate of approximately 10% to 15% per year.
Additionally, when impairments are in domains other than memory MCI is classified as nonamnestic-MCI. These individuals are believed to be more likely to develop other dementias (e.g., dementia with Lewy bodies).
In about one third or half of instances MCI may simply remain stable over time or even improve. The cause of MCI in and of itself remains unknown and there is no known prevention and treatment.
As with most medical conditions, a timely evaluation by a physician specializing in diagnosis and treatment of memory disorders is the best approach to assuring the optimal outcome of a memory problem.
