Neuropsychological tests are specifically designed tasks used to measure a psychological function known to be linked to a particular brain structure or pathway. 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.

Categories of neuropsychological tests

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.^[1]

Intelligence

Intelligence testing in a research context is relatively more straightforward than in a clinical context. In research, intelligence is tested and results are generally as obtained, however in a clinical setting intelligence maybe impaired so estimates are required for comparison with obtained results. Premorbid estimates can be determined through a number of methods, the most common include: comparison of test results to expected achievement levels based on prior education and occupation and the use of hold tests which are based on cognitive faculties which are generally good indicators of intelligence and thought to be more resistant to cognitive damage, e.g. language.

• Ammons Quick Test
• National Adult Reading Test (NART)
• Wechsler Adult Intelligence Scale (WAIS)
• Wechsler Intelligence Scale for Children (WISC)
• Wechsler Preschool and Primary Scale of Intelligence (WPPSI)
• Wechsler Test of Adult Reading (WTAR)

Memory

Memory is a very broad function which includes several distinct abilities, all of which can be selectively impaired and require undividual 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.^[1] 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.^[2] 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 or short term memory for information manipulation.^[3][4]

Language

Language functions include speech, reading and writing, all of which can be selectively impaired.

• Boston Diagnostic Aphasia Examination
• Boston Naming Test
• Comprehensive Aphasia Test (CAT)
• Lexical decision task
• Multilingual Aphasia Examination

Executive Function

Executive functions are an umbrella term for a various cognitive processes and sub-processes.^[5] The executive functions include: problem solving, planning, organisational skills, selective attention, inhibitory control and some aspects of short term memory.^[6]

• Tower of London Test
• Trail-Making Test (TMT) or Trails A & B
• Wisconsin card sorting task (WCST)
• Symbol Digit Modalities Test

Dementia specific

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. Tests such as these are by no means conclusive of deficits, but may give a good indication as to the presence or severity of dementia.

• Clinical Dementia Rating
• Dementia Rating Scale
• MCI Screen

Batteries assessing multiple neuropsychological function

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.

• Cambridge Neuropsychological Test Automated Battery (CANTAB)
• Cognistat (The Neurobehavioral Cognitive Status Examination)
• Cognitive Assessment Screening Instrument (CASI)
• Cognitive Function Scanner (CFS)
• Dean-Woodcock Neuropsychology Assessment System (DWNAS)
