In one of the first studies to look at the relationship between death and the two types of mild cognitive impairment (MCI), researchers suggest that people who have thinking problems but their memory is still intact might have a higher death rate in a period of six years compared to those who have no thinking or memory problems.
MCI can be a precursor to Alzheimer’s disease. There are two main types. In one type, the most noticeable symptom is memory loss. In people with the other type, language, attention, decision-making and other abilities are declining, but memory is still intact.
For the study, over 800 people with thinking problems and over 1,000 people with out thinking problems were followed for nearly six years. They were given tests at the start of the study and every 15 months to assess their thinking abilities. People with MCI with no memory loss had more than twice the death rate during the study than those without MCI, while people with MCI with memory loss had a 68 percent higher death rate during the study than those without MCI.
