About Dementia



What is Mild Cognitive Impairment (MCI)?

“Mild Cognitive Impairment” (MCI) refers to a condition in which there is a decline in one’s usual cognitive abilities e.g., (memory, language functions, reasoning) but not to the extent that it is obvious in daily living activities, like banking, driving, managing medication and taking care of usual responsibilities.   MCI has recently become of concern to medical practitioners because it can be a sign of progressive decline to a state of dementia.  This is true when the MCI is caused by Alzheimer changes in the brain.  There are other causes of MCI, however, that may be not cause progression or that may be amenable to treatment.
