Vision and Vestibular System Dysfunction Predicts Prolonged Concussion Recovery in Children

Area of Science:

• Pediatric neurology
• Sports medicine
• Ophthalmology

Background:

• Concussion is common in children, with up to one-third experiencing prolonged symptoms beyond four weeks.
• Vision and vestibular dysfunction frequently occur post-concussion, but their predictive value for recovery duration is unclear.

Purpose of the Study:

• To identify specific vision or vestibular problems that predict prolonged recovery in pediatric concussion patients.
• To investigate factors associated with delayed presentation for concussion care.

Main Methods:

• Retrospective cohort study of 432 pediatric patients (ages 5-18) treated at a subspecialty concussion program.
• Assessed vision and vestibular dysfunction at initial presentation.
• Defined prolonged recovery by clinical discharge criteria, including symptom resolution and return to normal activities.

Main Results:

• 88% of patients presented with vision or vestibular problems.
• Provocable symptoms with vestibulo-ocular reflex (VOR) and smooth pursuits, along with abnormal balance and accommodative amplitude (AA), predicted longer recovery times.
• History of motion sickness was linked to vestibular dysfunction; younger age, public insurance, and headache were associated with delayed care.

Conclusions:

• Vision and vestibular deficits are significant predictors of prolonged concussion recovery in children.
• Comprehensive assessments including smooth pursuits, saccades, near point of convergence (NPC), and accommodative amplitude (AA) are essential.
• Early identification and targeted interventions, including accommodations and rehabilitation, are vital for optimizing recovery.
