The LBC1921 took the Moray House Test at ages 11, 79, 87 and 90, and results at all four sittings were strongly correlated. The raw correlations between test scores at age 11 and at ages 79, 87 and 90 were .66, .51 and .55 respectively, and they rose to .73, .61 and .67 respectively after correction for the restriction of range in the LBC1921 ...

It is scored out of 100, with a higher score denoting better cognitive function. At the recommended cut-off scores of 88 and 83, the ACE was reported to have good sensitivity and specificity for identifying different forms of dementia and other impairments of memory and judgement (0.93 and 0.71; 0.82 and 0.96, respectively).

The researchers sought to validate their tool by looking into the associations between nearly 400,000 participants’ Brain Care Score at the beginning of the UK Biobank study between 2006 and ...
A 2006 study found that IQ scores were related to the number of traumas and symptoms of post traumatic stress disorder (PTSD) in children and adults. [37] Similarly, another study found that exposure to violence in the community and the subsequent distress, were related to a significant decrease in intelligence scores and reading abilities in ...
The team used health data from more than 350,000 people who had been recruited for the UK Biobank study between 2006 and 2010 and participated in follow-up assessments three times over the next ...
The idea of a collaboration between public institutions and private pharmaceutical companies to fund a large biomarker project to study AD and to speed up progress toward effective treatments for the disease was conceived at the beginning of the millennium by Neil S.
