Case records for neuropsychology practices
Your past cases, ready for the next one.
Paste a score table or upload a finished report. Casebook keeps every score in one record per patient, puts a mixed battery on one scale, and shows how a new profile compares with the cases your practice has already seen.
Private beta. Not yet open to new practices; the demo is open to anyone, with invented people: no sign-up, no card.

Every rail and every SD figure runs the same way: difficulty is negative and to the left. A rating scale: a higher T score there means more of what it rates, so its T 54 shows as -0.40 SD.

How it works
The scoring is done. Casebook is what comes after.
What is left after the scoring is six vendor portals, a PDF and a score table typed by hand. Casebook turns that into one record you can read and compare.
Bring the scores in
Paste a score table or upload a finished report. Casebook proposes one row per score, with the instrument, the informant and the age, and nothing is written until you have looked at the rows and pressed Commit.
- You
- Paste, upload or key the scores in.
- Casebook
- Proposes one row per score; rows it is unsure of start unticked. A report is read for that request and kept nowhere.

See the battery on one scale
A WISC-V index, a CVLT trial and a BRIEF composite in the same units, each pointing the right way, so difficulty always sits to the left.
- You
- Enter scores as the publisher reported them.
- Casebook
- Expresses each one as a deviation from its own mean, turns a symptom scale so that difficulty points the same way as on an ability scale, and folds a composite out when its parts are there so one testing is not counted twice.

Demonstration data · an invented case
Compare with your own cases
Each reading shows its rule, its checks and its published source, and says how many other cases in your series show it too: always a count with its denominator, never a percentage.
- You
- Open a case, or build a cohort from your own records.
- Casebook
- Links to the other cases that show the same reading. Below five cases a cohort figure is greyed out and marked unreliable rather than overstated.
Finding How many scores are low
2 of 7 composites sit at or below −1.5 SD, which is more than a battery of this size usually produces in someone with nothing wrong. What it means depends on whether they fall together in one domain or scatter across several.
The checks this reading ran Comparison Value Cut Met? At or below −1.5 SD 2 ≥ 2 met Visual-Motor Integration −2.67 ≤ −1.50 SD met Verbal Comprehension −1.67 ≤ −1.50 SD met Counts the composites at or below −1.5 SD and compares that count against how many a battery of the same size produces in people with nothing wrong. Subtests, rating scales and validity measures are left out of the count, and a measure given twice counts once. The threshold rises with the number of measures, because the chance of a low score does. The rule comes from adults aged 65 and over, screened cognitively normal, on a ten-measure battery from an ageing-research registry: at ten measures it calls 3 or more low scores uncommon, a count 2.91% of those adults showed (2 or more: 10.58%; Oltra-Cucarella et al. 2021). So it is the shape that carries here, not the exact figures. The pediatric studies that exist point the same way at comparable battery sizes, and carry the same dependence on ability — among children aged 7 to 17, 29.2% of those with below-average crystallized ability had a fluid score at or below the 5th percentile, against 9.0% of those above average (Cook et al. 2025).

Boundaries
What it will not do
It does not score
Scoring belongs to the publishers who own the norms, and you already pay for it. A score arrives already computed, by whichever platform you licensed to compute it.
It does not diagnose
No output names a disorder or ranks the likelihood of one. A test reads every sentence the software can produce and fails the build if one reaches for it.
It does not overstate
A “significant” verbal–performance split showed up in about 40% of the WAIS-R standardization sample, so Casebook reports at the rarity line, not the significance line. Subtest-level profile analysis was removed outright.
Answers
The arguments, with their sources
Every rule in Casebook was argued with the literature first, and three of the first four readings were weakened once the retest data was read properly.
- How unusual is a significant index split?Significance and rarity are different questions. Casebook reports at the rarity line.
- How many low scores does a healthy person have?What counts as unusual depends on how many tests you gave.
- How do you compare scores from different instruments?An index of 80, a scaled score of 6 and a T of 63 are largely one statement in four vocabularies.
Questions
Asked before anything else
Does it score tests?
No. A score reaches Casebook already computed, by whichever platform you licensed to compute it. Scoring belongs to the publishers who own the norms.
Does it make a diagnosis?
No. Casebook does not diagnose: no output names a disorder or ranks the likelihood of one, and a test that reads every sentence the software can produce fails the build if one reaches for it.
Does it store patient names?
No. A patient is a case code you choose, and there is no column for a name, a record number, an email, a phone or an address. What is stored, exactly.
What happens to a report I upload?
It is read for that one request, parsed into rows for you to review, and kept nowhere: no column, no cache, no copy on disk.
Can I bring in last year's reports?
Yes. Choose several finished reports at once: each gets its own case code and its own review, and is written only when you commit it. A spreadsheet with a case-code column brings in many cases in one paste.
Which instruments does it know?
The common pediatric and adult batteries, rating scales and validity measures. The full list, searchable.
Can I try it before talking to anyone?
Yes. The demonstration is the real product holding invented people: no sign-up, no card, nothing to uninstall.
See it with invented people.
The demonstration is the real product with a practice of invented cases already in it. Open a case, read a profile, follow a reading to its source.
New practices
New practices are set up by hand right now, and Casebook is not taking requests yet. The demonstration is open to anyone in the meantime: the real product, holding invented people.
Casebook will hold protected health information, so we sign a business-associate agreement with your practice before any patient data goes in.
