What is the difference between mild cognitive impairment and alzheimer's?

MCI-memory loss only. In dementia, not only memory, but also judgment, language, and other aspects are impaired. Mild cognitive impairment (mci) is a mild worsening of memory without those other changes. Mci may or may not progress to dementia. With my patients, i look for reversible causes, do baseline memory testing and repeat a year later. Slow eeg or prolonged cognitive evoked potential may signal pre-dementia.
Levels of impairment. Mild cognitive impairment (mci) means that there is one brain area that has problems. Having mci increases the risk of developing dementia. Some of those with mci will go on to develop alzheimers which is the most common type of dementia. Those with alzheimers have impairment in memory as well as at least one other area of brain functioning accompanied by loss of functioning in their life.
