MCI and Alzheimer’s
A related problem, known as mild cognitive impairment (MCI), can cause more severe memory problems; however, not all individuals with MCI will develop AD. Worldwide, Alzheimer’s disease or a related dementia affects over 44 million individuals. The risk of developing AD increases with age - affecting 1 out of 14 individuals over the age of 65 and 1 out of 6 individuals over the age of 80. AD is most common in elderly individuals over the ages of 65, although it can also affect individuals aged 40 to 65. To some extent, Alzheimer’s disease affects more women than it does men. While it remains unknown as to what is the exact cause of Alzheimer’s disease, risk factors such as age, family history, previous head injuries, and genetics, seem to play a significant role.
