MCI

MCI is an acronym used to refer to several unrelated topics across different fields. Notable uses include a medical condition, an airport code, a former telecommunications company, and a designation used by Minnesota correctional facilities.

In medicine, mild cognitive impairment (MCI) describes a level of cognitive decline that is greater than expected for a person’s age or education but not severe enough to interfere significantly with daily activities. MCI can involve memory loss and impairments in other cognitive domains and is categorized into subtypes such as amnestic and non-amnestic, single-domain and multiple-domain. Diagnosis relies on clinical assessment and objective cognitive testing, and while some individuals with MCI progress to dementia, others remain stable or improve. Management emphasizes monitoring, cardiovascular risk reduction, mental and physical activity, and treatment of coexisting conditions; there are no approved disease-modifying therapies for MCI.

In transportation, MCI is the IATA airport code for Kansas City International Airport, located in Kansas City, Missouri. The airport serves as a major regional hub and has undergone modernization to expand capacity and improve passenger experience.

In business, MCI Inc. refers to a telecommunications company originally established as MCI Communications Corporation. It grew through acquisitions and became MCI WorldCom after a merger with WorldCom in 1998. The company was later acquired by Verizon Communications in 2006, and its assets became part of Verizon’s enterprise and international divisions.

In corrections, MCI stands for Minnesota Correctional Institution, a designation used for certain state correctional facilities in Minnesota.
