Study says life span normal when Parkinson's does not affect thinking

In the past, researchers believed that Parkinson's disease did not affect life expectancy. But recent studies showed a somewhat shorter life span. Now a new study suggests that when the disease does not affect thinking skills ...

Evidence mounts that an eye scan may detect early Alzheimer's disease

Results from two studies show that a new, non-invasive imaging device can see signs of Alzheimer's disease in a matter of seconds. The researchers show that the small blood vessels in the retina at the back of the eye are ...

Mild cognitive impairment

Mild cognitive impairment (MCI, also known as incipient dementia, or isolated memory impairment) is a diagnosis given to individuals who have cognitive impairments beyond that expected for their age and education, but that do not interfere significantly with their daily activities. It is considered to be the boundary or transitional stage between normal aging and dementia. Although MCI can present with a variety of symptoms, when memory loss is the predominant symptom it is termed "amnestic MCI" and is frequently seen as a risk factor for Alzheimer's disease.

Studies suggest that these individuals tend to progress to probable Alzheimer’s disease at a rate of approximately 10% to 15% per year. Additionally, when individuals have impairments in domains other than memory it is classified as non-amnestic single- or multiple-domain MCI and these individuals are believed to be more likely to convert to other dementias (i.e. dementia with Lewy bodies).
