Agitation and Sleep Disruption After Severe Pediatric TBI
Mateo is a 14-year-old boy admitted to inpatient rehabilitation 6 weeks after a severe traumatic brain injury from a motor vehicle collision. Initial Glasgow Coma Scale was 4; he now opens eyes spontaneously, follows one-step commands inconsistently, and is in Rancho Los Amigos level IV. He is agitated, strikes staff during transfers, and sleeps only 3–4 hours per night. He takes melatonin 5 mg at bedtime. His parents are exhausted and ask for “something to calm him down.” He has no history of seizures. His exam shows bruxism, leg stiffness, and a distended abdomen with no bowel movement in 3 days. The team is considering antipsychotics, benzodiazepines, or a stimulant.
1. What are the most likely reversible contributors to Mateo’s agitation, and how would you sequence nonpharmacologic management before adding a new drug?
Read the worked answer
Treat agitation as a symptom rather than a diagnosis. Reversible contributors here include fecal impaction and constipation, pain from bruxism or occult injury, sleep deprivation, overstimulation, spasticity, and possibly occult seizures. Start with a bowel clean-out and a scheduled bowel regimen, a pain assessment, medication review, and EEG if episodes are paroxysmal. Nonpharmacologic sequence: (1) treat constipation and pain; (2) establish sleep hygiene with dark/quiet nights, daytime light and activity, and limited naps; (3) create a structured, low-stimulation schedule with a behavioral plan; (4) train family and staff to respond consistently; (5) reassess. Antipsychotics and benzodiazepines can worsen cognition, cause paradoxical agitation, and may prolong recovery; reserve them for unsafe behavior after reversible causes are addressed.
2. If agitation persists and threatens safety, propose a medication trial with rationale, dosing considerations, and monitoring.

Match the agent to the target. For persistent irritability with low arousal, amantadine 100 mg daily may be considered with age- and weight-appropriate adjustment. For severe agitation with autonomic arousal, low-dose propranolol or an SSRI may be reasonable; trazodone can help sleep. Avoid routine antipsychotics because of cognitive slowing and metabolic effects; if an antipsychotic is needed for acute safety, use the lowest dose for the shortest time. Start low, monitor heart rate, blood pressure, sedation, sleep, and behavior with a structured scale, and continue nonpharmacologic measures. Reassess in 1–2 weeks, document off-label use, and align with family goals.
3. What criteria would you use to judge readiness for home and school re-entry, and what supports would you arrange?
Read the worked answer
Readiness requires medical stability, predictable sleep, safe transfers, no unsafe aggression, and a family who can supervise and respond to agitation. Use a team checklist and a gradual trial pass. For school, arrange an IEP or 504 plan with cognitive and behavioral supports, a quiet space, a nurse plan, transportation, and a phased return. For home, assess environmental safety, supervision, respite, and follow-up. Involve the family in goal setting and identify a single rehabilitation coordinator. Re-entry is a process, not a discharge decision; schedule early follow-up and a school observation.
