With increasing age, the probability of a person experiencing memory impairment is getting higher. The lightest forms of memory impairment can be characterized by our own perception that there is memory that has been lost because of the decline of memory function.
The light cognitive impairment is a more severe form of memory loss. This disorder is classified as a significant memory deficit without impaired function. Generally, patients with light cognitive impairment are still able to live independently, but show memory impairment as light Alzheimer's disease patients.
