Introduction: Computerized neuropsychological tests are effective in assessing different cognitive domains, but are often limited by the need of proprietary hardware and technical staff. Web-based tests can be more accessible and flexible. We aimed to investigate validity, effects of computer familiarity, education, and age, and the feasibility of a new web-based self-administered neuropsychological test battery (Memoro) in older adults and seniors.

Method: A total of 62 (37 female) participants (mean age 60.7 years) completed the Memoro web-based neuropsychological test battery and a traditional battery composed of similar tests intended to measure the same cognitive constructs. Participants were assessed on computer familiarity and how they experienced the two batteries. To properly test the factor structure of Memoro, an additional factor analysis in 218 individuals from the HUNT population was performed.

Results: Comparing Memoro to traditional tests, we observed good concurrent validity (r = .49-.63). The performance on the traditional and Memoro test battery was consistent, but differences in raw scores were observed with higher scores on verbal memory and lower in spatial memory in Memoro. Factor analysis indicated two factors: verbal and spatial memory. There were no correlations between test performance and computer familiarity after adjustment for age or age and education. Subjects reported that they preferred web-based testing as it allowed them to set their own pace, and they did not feel scrutinized by an administrator.

Conclusions: Memoro showed good concurrent validity compared to neuropsychological tests measuring similar cognitive constructs. Based on the current results, Memoro appears to be a tool that can be used to assess cognitive function in older and senior adults. Further work is necessary to ascertain its validity and reliability.

Objective: To report the psychometric properties of an alternative instrument to the cognitive subscale of the Alzheimer's Disease Assessment Scale, a neuropsychological test battery (NTB) for measuring drug efficacy in Alzheimer disease clinical trials.

Design: The NTB was evaluated in a randomized, double-blind, placebo-controlled trial of AN1792(QS-21) (synthetic beta-amyloid plus an adjuvant) (300 patients) and isotonic sodium chloride solution (72 patients). The test-retest reliability of the NTB was examined, and the NTB was correlated with other cognitive (cognitive subscale of the Alzheimer's Disease Assessment Scale and Mini-Mental State Examination) and functional (Disability Assessment Scale for Dementia and Clinical Dementia Rating Sum of Boxes) measures. In addition, a factor analysis was performed on NTB components. Finally, the sensitivity of the NTB to change was assessed as a function of Mini-Mental State Examination performance.

Results: The NTB had high test-retest reliability at 6 (Pearson product moment correlation [r] = 0.92) and 12 (r = 0.88) months. Internal consistency was high (Cronbach alpha = 0.84). The correlations between the NTB z score and scores on traditional measures of cognition and function were significantly different from 0 (P Conclusions: The NTB exhibits excellent psychometric properties and seems to be a reliable and sensitive measure of cognitive change in patients with mild to moderate Alzheimer disease. The psychometric properties of the NTB suggest that it may have particular utility in evaluating drug efficacy in clinical trials in which patients with mild Alzheimer disease are included.

Neuropsychological tests are specifically designed tasks that are used to measure a psychological function known to be linked to a particular brain structure or pathway.[1] Tests are used for research into brain function and in a clinical setting for the diagnosis of deficits. They usually involve the systematic administration of clearly defined procedures in a formal environment. Neuropsychological tests are typically administered to a single person working with an examiner in a quiet office environment, free from distractions. As such, it can be argued that neuropsychological tests at times offer an estimate of a person's peak level of cognitive performance. Neuropsychological tests are a core component of the process of conducting neuropsychological assessment, along with personal, interpersonal and contextual factors.

Most neuropsychological tests in current use are based on traditional psychometric theory. In this model, a person's raw score on a test is compared to a large general population normative sample, that should ideally be drawn from a comparable population to the person being examined. Normative studies frequently provide data stratified by age, level of education, and/or ethnicity, where such factors have been shown by research to affect performance on a particular test. This allows for a person's performance to be compared to a suitable control group, and thus provide a fair assessment of their current cognitive function.

According to Larry J. Seidman, the analysis of the wide range of neuropsychological tests can be broken down into four categories. First is an analysis of overall performance, or how well people do from test to test along with how they perform in comparison to the average score. Second is left-right comparisons: how well a person performs on specific tasks that deal with the left and right side of the body. Third is pathognomic signs, or specific test results that directly relate to a distinct disorder. Finally, the last category is differential patterns, which are typically used to diagnose specific diseases or types of damage.[2]

Most forms of cognition actually involve multiple cognitive functions working in unison, however tests can be organised into broad categories based on the cognitive function which they predominantly assess.[3]

Intelligence testing in a clinical setting intelligence can involve premorbid estimates, determined through a number of methods, for comparison with obtained results. For example, test results can be compared to expected achievement levels based on prior education and occupation.

Memory is a very broad function which includes several distinct abilities, all of which can be selectively impaired and require individual testing. There is disagreement as to the number of memory systems, depending on the psychological perspective taken. From a clinical perspective, a view of five distinct types of memory, is in most cases sufficient.[3] Semantic memory and episodic memory (collectively called declarative memory or explicit memory); procedural memory and priming or perceptual learning (collectively called non-declarative memory or implicit memory) all four of which are long term memory systems; and working memory or short term memory.[4] Semantic memory is memory for facts, episodic memory is autobiographical memory, procedural memory is memory for the performance of skills, priming is memory facilitated by prior exposure to a stimulus and working memory is a form of short term memory for information manipulation.[5][6]}

Executive functions is an umbrella term for a various cognitive processes and sub-processes.[7] The executive functions include: problem solving, planning, organizational skills, selective attention, inhibitory control and some aspects of short term memory.[8]}

Neuropsychological tests of visuospatial function should cover the areas of visual perception, visual construction and visual integration.[9] Though not their only functions, these tasks are to a large degree carried out by areas of the parietal lobe.[3]

Dementia testing is often done by way of testing the cognitive functions that are most often impaired by the disease e.g. memory, orientation, language and problem solving. Gender inequality can also be called gender discrimination or sexism.

There are some test batteries which combine a range of tests to provide an overview of cognitive skills. These are usually good early tests to rule out problems in certain functions and provide an indication of functions which may need to be tested more specifically.}

The most beneficial factor of neuropsychological assessment is that it provides an accurate diagnosis of the disorder for the patient when it is unclear to the psychologist what exactly the patient has. This allows for accurate treatment later on in the process because treatment is driven by the exact symptoms of the disorder and how a specific patient may react to different treatments. The assessment allows the psychologist and patient to understand the severity of the deficit and to allow better decision-making by both parties.[10]

The aim of the present multi-center project is the development of a UDSNB adaptation for the Italian-speaking population (I-UDSNB), including a newly developed tablet-based application to aid the experimenter in test administration and scoring. Here, we report the reference norms obtained from the data collected in a cohort of 433 Italian healthy individuals.

The initiative, involving 17 centers members of the Virtual Dementia Institute of the RIN (Rete Italiana di Neuroscienze e Neuroriabilitazione-Italian Network of Neuroscience and Neuro-rehabilitation), was supported by a grant from the Italian Ministry of Health. The bases for the creation of the I-UDSNB were discussed during a consensus meeting in February 2020. On that occasion, representatives from six Scientific Institutes for Research, Hospitalization and Healthcare (IRCCS) discussed the feasibility to extend the initiative of the NACC to the Italian context. Permission was requested from the copyright owner, and Prof. Sandra Weintraub accepted to act as an external advisor to the project in the representation of the UDSNB group. The translation/adaptation was based on the American version of UDSNB (UDSNB 3.0, [25]). Then, the six centers participating in the consensus meeting created and revised through feedbacks the materials and the manual specifying the procedures for test administration and scoring. The tablet application was created and underwent a procedure of beta-testing, i.e., the centers tested the application, reporting criticisms and possible improvements to be implemented. A system allowing a web-based data entry was associated to the application, with the possibility to access and download the data via reserved credentials. In February 2021, after the approval of the project by the local ethics committees, the collection of normative data started, involving 14 centers that recruited 433 participants. In November 2021, a working group involving representatives of four centers defined the common procedures and performed the statistical analyses leading to the definition of reference norms.
