What Neuropsychological Testing Evaluates Neuropsychological testing provides objective measurement of cognitive function after concussion. The evaluation assesses memory (learning and recall), attention (sustained focus and divided attention), processing speed (how quickly your brain handles information), executive function (planning, organization, cognitive flexibility), and reaction time. Results identify which specific cognitive domains are impaired and how severely (Echemendia et al., 2013). This matters because subjective cognitive complaints ("I feel foggy") don't tell clinicians which cognitive systems are dysfunctional or how to target treatment. Two patients who both report "brain fog" may have completely different underlying profiles: one has impaired processing speed with intact memory, while the other has memory encoding deficits with normal processing speed. Their treatment plans differ accordingly. Neuropsychological testing also provides baseline comparison (if pre-injury testing exists), tracks recovery objectively, and supports return-to-work and return-to-play decisions with measurable data rather than subjective symptom reports alone. Cognitive Domains Tested Verbal memory. Tests evaluate your ability to learn new verbal information (word lists, stories) and recall it after a delay. Concussion commonly disrupts memory encoding (getting information in) more than retrieval (getting it back out). This means you hear information but it doesn't "stick" as effectively as it did pre-injury. Visual memory. Measures your ability to remember visual information (designs, spatial locations, faces). Visual memory uses different neural pathways than verbal memory, and concussion affects them to different degrees in different patients. Processing speed. How quickly you can perform cognitive operations. Measured through timed tasks requiring simple decisions or symbol matching. Processing speed is one of the most sensitive indicators of concussion effects and often the first domain to show measurable decline and the last to fully normalize. Attention and concentration. Tests measure sustained attention (maintaining focus over time), selective attention (focusing on relevant while ignoring irrelevant), and divided attention (managing multiple information streams simultaneously). Attention deficits produce the "can't concentrate" complaint common after concussion. Executive function. Higher-order cognitive abilities: planning, cognitive flexibility (switching between tasks), inhibition (suppressing automatic responses), and problem-solving. Executive function deficits manifest as difficulty organizing thoughts, poor decision-making, reduced multitasking ability, and personality changes (impulsivity, rigidity). Reaction time. How quickly you respond to stimuli. Simple reaction time (respond to one stimulus) and choice reaction time (respond differently to different stimuli) are both measured. Slowed reaction time has direct implications for driving safety, sport participation, and occupational function. Language function. Word-finding, verbal fluency (generating words by category or starting letter), and naming. Concussion occasionally affects word-finding, producing the "tip of the tongue" phenomenon patients describe as part of cognitive fog. Types of Tests Used Computerized tests (brief, 20-30 minutes): ImPACT: Most widely used computerized concussion assessment. Measures verbal memory, visual memory, processing speed, and reaction time. Provides comparison to pre-injury baseline if available. SCAT5 cognitive screen: Brief sideline assessment including orientation, memory, and concentration. Used for initial concussion recognition, not comprehensive evaluation. CNS Vital Signs: Computer-based battery measuring memory, processing speed, executive function, and reaction time. Paper-based comprehensive battery (2-4 hours): Trail Making Test: Measures processing speed and cognitive flexibility. Hopkins Verbal Learning Test: Evaluates verbal learning and memory. Brief Visuospatial Memory Test: Assesses visual memory. Symbol Digit Modalities Test: Measures processing speed. Stroop Color-Word Test: Tests selective attention and inhibition. Controlled Oral Word Association Test: Evaluates verbal fluency. Supporting Cognitive Recovery With Movement Physical movement during cognitive breaks improves blood flow to attention-regulating brain regions: JME 1 Cervical rotation between cognitive tasks improves vertebral artery flow to attention centers. JME 14 Chin tucks release the suboccipital tension that compounds cognitive fatigue during testing and daily function. JME 6 Cervical flexion counters the forward head posture from sustained computer or reading work. JME 44 Shoulder mobility provides physical reset during cognitive work breaks. Start your 14-day free trial for mobility breaks that refresh cognitive capacity. Upper Body Reset JME 38 Shoulder mobility opens the chest and resets posture after sustained cognitive work. JME 151 Thoracic mobility reverses the flexed posture from hours of desk-based cognitive rehabilitation. JME 166 Scapular mobility corrects rounded shoulders from sustained seated cognitive work. JME 152 Upper back extension restores posture after extended periods of concentrated mental effort. When to Get Neuropsychological Testing Cognitive symptoms persisting beyond 2-3 weeks. If concentration, memory, or processing speed complaints continue beyond the expected recovery window, formal testing quantifies the deficits and guides rehabilitation. Discrepancy between subjective complaints and observed function. Sometimes patients report significant cognitive problems but perform normally on testing (suggesting anxiety or depression is amplifying perceived deficits). Other times, patients minimize complaints but show measurable impairment. Testing clarifies the actual cognitive status. Return-to-work or return-to-play decisions. For patients in cognitively demanding jobs (surgeons, pilots, financial analysts) or high-risk sports, objective testing provides measurable evidence of cognitive recovery. Subjective "I feel fine" is insufficient for safety-critical return decisions. Academic accommodations. Students with concussion need documented cognitive deficits to qualify for academic accommodations (extended test time, reduced course load, note-taking assistance). Neuropsychological testing provides this documentation. Baseline comparison availability. If pre-injury baseline testing exists (common in organized sports programs), post-concussion testing comparison provides the most precise assessment of concussion-related change versus pre-existing cognitive patterns. Interpreting Results Comparison to norms. Without baseline testing, your scores are compared to age-matched and education-matched normative data. Scores below the 16th percentile (one standard deviation below average) in the context of concussion history suggest injury-related impairment. Comparison to baseline. When pre-injury baseline testing exists, a decline in specific domains provides stronger evidence of concussion-related change. The Reliable Change Index determines whether score changes exceed normal test-retest variability. Pattern analysis. Neuropsychologists interpret patterns across domains, not individual test scores. A pattern of slow processing speed with intact memory suggests different pathology than impaired memory encoding with normal speed. Pattern interpretation guides targeted rehabilitation. Effort and validity. Testing includes embedded validity measures to detect suboptimal effort. If a patient isn't trying their best (due to fatigue, symptom exaggeration, or secondary gain), validity measures identify unreliable results. This protects against both over-diagnosis and under-diagnosis. Support cognitive recovery with simplmobility's mobility breaks designed for concentration renewal. How long does neuropsychological testing take? Computerized screening tests (ImPACT, CNS Vital Signs) take 20-30 minutes. Comprehensive paper-based neuropsychological evaluation takes 2-4 hours, including breaks. The comprehensive evaluation provides more detailed and reliable information but is more fatiguing. Schedule testing for your best cognitive time of day (usually morning). Is neuropsychological testing required after every concussion? No. Most concussions resolve within 2-4 weeks without formal testing. Testing is recommended when cognitive symptoms persist beyond 3-4 weeks, when return-to-work/play decisions require objective data, when academic accommodations are needed, or when the cognitive profile needs clarification for treatment planning. Will my concussion show up on neuropsychological testing? Not always. Neuropsychological tests measure cognitive function, not brain injury directly. Patients tested after full recovery show normal performance. Patients tested early (within days of injury) typically show measurable deficits. The timing of testing relative to injury determines whether deficits are detectable. What happens after neuropsychological testing? The neuropsychologist provides a detailed report identifying impaired domains, preserved domains, and specific recommendations. Recommendations may include cognitive rehabilitation strategies, academic or workplace accommodations, readiness for return to activity, or referral for additional treatment (vestibular therapy, psychological support, medication management).
