Mild cognitive impairment causes mild but noticeable changes in decrease of cognitive abilities like thinking abilities and memory power. It is an intermediate stage between cognitive decline of normal aging and the severe signs of dementia. In amnestic MCI, person starts to forget important information's like appointments, conversations, etc. Whereas in nonamnestic MCI, person’s thinking ablility is hampered. There is no cause for MCI, but studies show that shrinkage of hippocampus, enlargement of brain’s fluid-filled spaces and reduced use of glucose may be possible causes. Risk factors for MCI- increasing age, lifestyle problems and a presence of a specific form of gene APOE-e4, though presence of this gene doesn’t assure that an individual can get MCI. The prevalence of MCI varies by age group. 6.7% for ages 60–64; 8.4% for ages 65–69, 10.1% for ages 70–74, 14.8% for ages 75–79, and 25.2% for ages 80–84. No medications are there to treat MCI properly.
