Neurocognitive Testing

Who this is for: Written for providers deciding whether neurocognitive testing fits a patient and for patients who want to know what to expect.

Measuring how a person thinks, not just how they feel

After a crash, patients often say "I can't focus," "I forget everything" or "my brain feels slow." Those reports matter, but they are hard to quantify. Neurocognitive testing turns them into measurements of specific thinking skills: attention, working memory, learning and recall, processing speed, reaction time and the ability to switch between tasks. These are the skills people rely on to work, drive, study and manage daily life.

Neurocognitive testing measures how a person thinks, not just how they feel.

What the tests involve

The assessments are computer-based short tasks: remembering items, responding quickly to a symbol, matching patterns or tracking changing information. Instructions come before each task, often with practice items. There is nothing to study and there are no trick questions. Most patients describe it as a series of simple puzzles that grow more challenging. No computer experience is needed.

Conditions that affect results

Performance reflects the person on that day. Poor sleep, pain, certain medications, illness, anxiety and low effort can all affect scores. The technician records relevant conditions at the start, and the physician takes them into account. Coaching or rehearsing works against accurate results.

How scores are interpreted

Scores are compared with reference data, generally adjusted for factors such as age. The neurologist looks for patterns across tasks and compares them with eye-movement findings, other measures and the symptom history. Education, language and pre-existing conditions such as ADHD or learning differences are considered so results are interpreted fairly.

A pattern across several measures means more than a single low score.

How findings inform care

Treating providers use neurocognitive findings when deciding about activity pacing, work or school accommodations, return to driving and referral for neuropsychology or other specialty care. Braintree helps coordinate specialty evaluations when the provider requests it. The provider remains in charge of care.

Common candidates

Typical referrals are patients whose concentration, memory, word-finding or processing complaints persist after an accident, or whose families report noticeable changes.
