A new study Not long ago published in the journal JAMA Psychiatryinvestigates whether or not changes in boldness precede the onset of mild cognitive impairment or dementia.
The researchers – who were jointly led By means of Antonio Terracciano & Angelina Sutin, both associate professors at Florida State University College of Medicine in Tallahassee – investigated dementia-related characterism changes in a cohort of more than 2,000 people.

The longitudinal study followed these participants for 36 years, during which time the researchers looked for increased neuroticism, decreased conscientiousness, and other characterism changes.
It is known that boldness And behavioral changes accompany Alzheimer's disease. Caregivers provide irritability, moodiness, or loss of motivation in their patients, which negatively affect their quality of life.
These are clinical criteria for diagnosing the illness, but it remains debatable whether or not these changes occur before the onset of dementia – as a consequence of the brain pathologies that characterize the disease And http://radiologyebook.net/video-medical occur years before a formal diagnosis – or whether boldness changes are just independent risk factors for the condition.
boldness stays the same before onset
For the new study, 2,046 participants were recruited from the Baltimore Longitudinal Study of Aging. Of them, 45.5 percent were female, And the average age was 62 years.
During the follow-up period, tiny over 5 percent of the participants developed mild cognitive impairment (MCI) And 12.5 percent developed dementia. The majority of these patients had Alzheimer's disease.
MCI describes a level of cognitive decline that affects seniors. Although it is not serious enough to interfere with the daily functioning of those it affects, MCI is considered to be a strong predictor of Alzheimer's disease.
