A head injury can affect thinking, memory, behavior, emotion, sleep, balance, and daily function. Some changes are reported by the injured person, some are observed by others, and some appear in clinical testing. A careful record keeps those sources separate and follows change over time without diagnosing from a checklist.

A symptom checklist, an imaging result, a diagnosis, a functional change, and a medical causation opinion are different parts of the record.

Respond to urgent symptoms first

Worsening headache, repeated vomiting, weakness or numbness, decreased coordination, seizure, slurred speech, unusual behavior, unequal pupils, increasing confusion or agitation, inability to recognize people or places, or inability to wake can require emergency medical care. Follow current clinical instructions and call emergency services when appropriate.

The CDC’s mild TBI and concussion symptom resource organizes possible symptoms into physical, thinking or memory, social or emotional, and sleep categories. It also explains that symptoms differ among people, may change during recovery, and can overlap with other health problems.

Preserve the acute event and care record

  • Impact sequence, head or body contacts, restraint, air-bag deployment, reported loss or alteration of consciousness, amnesia, confusion, and witness observations
  • EMS and emergency examinations, Glasgow Coma Scale or other recorded measures, neurologic findings, diagnoses, precautions, medication, and discharge instructions
  • Original images, radiology reports, orders, comparison studies, laboratory results, consultations, and reasons recorded for or against further testing
  • First report and later course of headache, dizziness, nausea, vision or hearing change, light or sound sensitivity, balance, fatigue, sleep, attention, memory, mood, or behavior
  • Follow-up appointments, referrals, therapies, attendance, response, restrictions, return precautions, and changes in the clinical assessment

Read imaging within its clinical setting

The American College of Radiology Head Trauma criteria organize imaging questions by the timing and severity of trauma, neurologic findings, prior imaging, new or progressive deficits, and subacute or chronic symptoms. A person-specific clinician decides what testing is appropriate.

An abnormal image does not explain every reported change, and a normal study does not by itself resolve every clinical question. Preserve the examination, history, study limitations, comparison, evolving symptoms, and the clinician’s reasoning instead of treating the scan as the entire record.

Create a before-and-after function map

  • Pre-crash work, school, caregiving, household, financial, driving, social, exercise, screen, reading, and sleep routines
  • Specific post-crash errors, missed steps, forgotten tasks, slowed work, reduced stamina, sensory triggers, irritability, emotional changes, and safety concerns
  • Date, setting, task, duration, cueing or assistance, consequence, recovery time, and whether the observation was repeated
  • Work reviews, schedules, accommodations, school records, calendars, messages, device activity, and contemporaneous notes that may corroborate change
  • Later injury, medication, pain, sleep disruption, psychological condition, substance use, prior head injury, aging, or another factor a clinician may consider

Use collateral observations carefully

Family members, coworkers, teachers, friends, and caregivers may observe changes that the injured person does not notice. Record concrete examples in the observer’s own words, along with the date and context. Avoid coaching, diagnostic labels, identical scripted statements, or unsupported estimates. Privacy and employment concerns should be considered before collecting or sharing sensitive records.

Separate testing, diagnosis, causation, and damages

North Carolina Rule of Evidence 702 requires qualified opinion testimony to rest on sufficient facts or data, reliable principles and methods, and reliable application. The opinion foundation should identify the event history, baseline, medical course, testing, effort and validity information when relevant, collateral evidence, alternative explanations, and uncertainty.
