The negative predictive value for the total sample was 0.93 making it a good tool to rule out cognitive impairment. On all measures the GPCOG performed at least as well as the mini–mental state examination (MMSE). [1] [2] Of note, positive and negative predictive values depend on the prevalence of the disorder in the studied population.
The Montreal Cognitive Assessment (MoCA) is a widely used screening assessment for detecting cognitive impairment. [1] It was created in 1996 by Ziad Nasreddine in Montreal, Quebec. It was validated in the setting of mild cognitive impairment (MCI), and has subsequently been adopted in numerous other clinical settings. This test consists of 30 ...
Serial sevens (or, more generally, the descending subtraction task; DST), where a patient counts down from one hundred by sevens, is a clinical test used to test cognition; for example, to help assess mental status after possible head injury, in suspected cases of dementia or to show sleep inertia.
The Woodcock–Johnson Tests of Cognitive Abilities is a set of intelligence tests first developed in 1977 by Richard Woodcock and Mary E. Bonner Johnson (although Johnson's contribution is disputed). [1] It was revised in 1989, again in 2001, and most recently in 2014; this last version is commonly referred to as the WJ IV. [2]
[2] [4] The ACE-R [1] was a development of the earlier ACE which also incorporated the MMSE, but had clearly defined subdomain scores. The ACE-III [6] was developed to improve the performance of certain parts of the test and also to avoid a potential copyright violation by replacing the elements shared with the MMSE. [7]

When considering tests of cognitive ability, it is paramount to consider evidence for their reliability, validity, length, and mode of administration (e.g., some assessments require a trained administrator to be present with the respondent). It is also essential to understand which cognitive abilities are measured by each test and sub-test. [1]
The NEPSY-II test battery also added a new domain, Social Perception, and eleven new subtests in addition to removing four of the old subtests. The test battery thus consists of six domains comprising 32 subtests. The NEPSY-II also exists in two versions: one for ages 3 through 4 and one for ages 5 through 16.
