5 MCI characteristics:
1) Memory impairment is noticed by the individual or by his/her family member(s).
2) Daily life routines appear to be normal.
3) Basic cognitive function is normal.
4) There is an apparent memory disorder that can not be explained by the individual’s age and/or education level.
5) MCI is not dementia.

MCI is hard to notice in around 1 out of 4 individuals 65 years or older, and progresses gradually. This is the moment when cognitive functions fall below the age-appropriate level and where dementia is called Mild Cognitive Impairment (MCI). Although cognitive functions such as memory, decision, reasoning and execution may start to have problems, MCI has no impact on daily life.
Individuals with MCI, also known as “Dementia Reserve”, have a very high probability of developing dementia if it is not properly treated or prevented. Therefore, prevention and improving one’s lifestyle is important at this stage to stop its progress.
Being able to diagnose MCI at an early stage is an advantage not only for early prevention, but also for the individual to be able to understand the disease more clearly than after having dementia.
