Neuropsychological testing integrates psychology, psychometrics, neuroscience, clinical neuropsychology, and psychiatry to assess brain functioning in children, adults, or elderly.
Testing assesses one’s ability to reason and conceptualize, recall and understand spoken and written language, and collaborate the senses of vision, hearing, touch, and smell to perform skilled, calibrated movements.
Neuropsychological testing identifies patterns of disruption in one’s abilities that could indicate brain dysfunction.
When is Neuropsychological Testing Needed?
Neuropsychological testing is indicated where the nature and degree of abnormality and its maturational outcome begin to affect average neural growth and cognitive functioning.
The adult brain suffers damage through the toxicity of alcohol abuse, lead exposure, and parental drug abuse. Childhood trauma could be triggered by neonatal complications linked to hyaline membrane disease, respiratory distress, hyperbilirubinemia, asphyxia, bronchopulmonary dysplasia, and apnea.
Testing assesses the degree of cognitive compromise. ADHD neuropsychological testing examines cognitive impairment in working memory, reaction time, impulse control, and intelligence.
Who Does Neuropsychological Testing?
A neuropsychologist would be a licensed clinical or school psychologist with a Psy.D. or Ph.D. who studies brain functioning and cognitive behavior.
The difference between psychological and neuropsychological testing
The clinical psychologist is invested in studying emotional and behavioral disorders and learning disabilities that create short-term anxiety, depression, and trauma.
The neuropsychologist conducts a battery of tests to probe the neuropathological basis of severe diseases like Alzheimer’s, dementia, OCD, and traumatic brain injuries.
How often should neuropsychological testing be done?
Federal education law requires that students with intellectual or learning disabilities undergo neuropsychological evaluation every 2 to 3 years to update behavioral modification, therapy, or drug treatment depending on individual progress.
What does neuropsychological testing diagnose?
The process of neuropsychological testing involves a battery of tests assessing cognitive skills that evaluate historical information,
behavioral markers, and psychological investigations for micromapping neuropsychological functioning.
The neuropsychological testing process, specifically its brain exam protocol, samples a broad range of behavioral characteristics, pinpointing specific deficits or problems and draws an accurate portrayal of the subject’s overall brain neuropsychology.
How long does neuropsychological testing take?
Depending upon the comfort zone of the patient, neuropsychological testing takes 2 to 4 hours to administer various tests with adequate breaks and may extend to 8 hours for severe disorders.
Neuropsychological Testing Measures and Assessments
This is what to expect in neuropsychological testing and the range of evaluated behavioral parameters.
- General Cognitive Ability
General cognitive ability is assessed using standardized intelligence tests, such as the Wechsler Intelligence Scale for Children Third Edition (WISC-III), the Stanford Binet Intelligence Scale Fourth Edition, and the Kauffman Assessment Battery for Children.
The Brainview test assesses how stress, memory, and cognition are compromised while measuring heart and metabolic rates.
- Language Abilities
A deeper understanding of aphasia that damages brain centers controlling speech and language knowledge has driven neuropsychology’s growth. Thus, neuropsychological testing using batteries, such as the Neurosensory Center Comprehensive Examination of Aphasia, also includes tests by speech pathologists and other psychologists, such as the Peabody Picture Vocabulary Test-Revised.
- Attention
Attention is a multidimensional construct involving tests that assess various aspects, such as vigilance, that overlap with the brain’s executive functions. The primary attention protocols under NP testing include the Gordon Diagnostic System, one of the continuous performance tests, The Contingency Naming Test, and the Arithmetic, Digit Span, Coding, and Symbol Search subtests from the WISC-III.
- Executive Functions
The brain’s executive functions include planning, categorizing, regulating, and monitoring specific goal-purposed behavior.
In the past, the assessment of mental skills and enabled activities such as problem-solving and abstract reasoning were tested informally by comparison with control models.
The domain of assessing executive functions has vastly improved to include measures such as the Wisconsin Card Sorting Test, the Tower of London, and the Children’s Category Test. Executive function assessment is instrumental in determining the scope and extent of a child’s adaptive functioning.
- Corticosensory and Motor Capacities
The traditional neurological examination of cortical sensory and motor skills include finger localization, neurogenesis, graphesthesia, sensory extinction, and left-right orientation, which are rigorously tested under various standardized assessment procedures.
- Academic skills
These are neurophysiological achievement tests designed to assess reading, writing, and mathematics skill levels appropriate for the age and experience of students.
- Emotional status
These tests measure the personality trait through questionnaires and sentence completion modules.
Benefits and Limitations of Neuropsychological Testing
It becomes possible to fully evaluate, diagnose, and map the pattern of the psychological changes the individual has undergone. Understanding cognitive impairment enables adequate treatments that cure the underlying condition.
Neuropsychological testing for Alzheimer’s disease: NP testing unravels the causative factors behind dementia, agitation, anxiety, mood swings, and unusual locomotor movements.
Neuropsychological testing for Parkinson’s disease: PD patients benefit by early detection of cognitive disability and difficulty in task management, paving the way for more result-oriented treatment regimes.
Neuropsychological testing for mental disorders: NP testing leads to the mapping of skills associated with reading, language comprehension, memory recall, learning pathways, problem resolution, and mood enhancement techniques.
Detect Learning Disabilities
Neuropsychological brain testing detects the root causes of learning disabilities, which is halfway to treating the disability with medication and therapy.
Improved Decision Making
Thorough psychological testing enables patients to gather indispensable and accurate information regarding neural health and suppressed issues. Patients with improved knowledge of their condition are empowered to make informed decisions that are more likely to bring stability to their lives.
Detect Ailment
Where physical pathology does not elicit clues regarding cognitive impairment, psychological and neuropsychological testing offers a credible alternative to ailment detection, one that reinforces supportive drug therapy.
Limitations of NP Testing
Neuropsychological tests identifying cognitive impairments stemming from neural damage cannot predict how the patients are likely to function in real-world situations when they operate independently, if they return to work, or follow high-level competitive performance.
Neuropsychological data-driven testing is most accurate when the tasks performed during testing closely simulate the patient’s everyday challenges and vocational ambiance.
Accurately predicting the patient’s working potential requires a careful assessment of medical history, cognitive damage characteristics, emotional and behavioral deviations, motivational readiness to rejoin work, and the patient’s family support circumstances.
Conclusion
Neuropsychological testing is the behavioral protocol for testing your brain and is a close estimation of cognitive impairment.
The detailed case history of the patient, inferences drawn from behavioral observation, interviews, and data culled from various sources are popular neuropsychological assessment tools.
As we transit the stages of childhood, adolescence, adulthood to seniority and senility, testing surveys all aspects concerning memory evaluation, speed and skill of psychomotor activity, visual-spatial and visual-auditory skills, tactile perception, language and attention to better understand whether brain tests indicate normal functioning or identify the underlying disorder.
