AI Article Synopsis
- Up to one-third of children with concussions experience prolonged symptoms, often related to vision and vestibular issues, and this study investigates which specific dysfunctions predict a longer recovery time.
- A total of 432 pediatric patients' records were analyzed, revealing that 88% had vision or vestibular problems, with certain symptoms like abnormal balance and difficulty with smooth pursuits correlating with extended recovery periods.
- The findings suggest that vision and vestibular assessments should be part of concussion evaluations, especially considering factors like motion sickness history and disparities in access to care indicated by public insurance.
Article Abstract
Objective: Up to one-third of children with concussion have prolonged symptoms lasting beyond 4 weeks. Vision and vestibular dysfunction is common after concussion. It is unknown whether such dysfunction predicts prolonged recovery. We sought to determine which vision or vestibular problems predict prolonged recovery in children.
Design: A retrospective cohort of pediatric patients with concussion.
Setting: A subspecialty pediatric concussion program.
Patients (or Participants): Four hundred thirty-two patient records were abstracted.
Assessment Of Risk Factors: Presence of vision or vestibular dysfunction upon presentation to the subspecialty concussion program.
Main Outcome Measures: The main outcome of interest was time to clinical recovery, defined by discharge from clinical follow-up, including resolution of acute symptoms, resumption of normal physical and cognitive activity, and normalization of physical examination findings to functional levels.
Results: Study subjects were 5 to 18 years (median = 14). A total of 378 of 432 subjects (88%) presented with vision or vestibular problems. A history of motion sickness was associated with vestibular dysfunction. Younger age, public insurance, and presence of headache were associated with later presentation for subspecialty concussion care. Vision and vestibular problems were associated within distinct clusters. Provocable symptoms with vestibulo-ocular reflex (VOR) and smooth pursuits and abnormal balance and accommodative amplitude (AA) predicted prolonged recovery time.
Conclusions: Vision and vestibular problems predict prolonged concussion recovery in children. A history of motion sickness may be an important premorbid factor. Public insurance status may represent problems with disparities in access to concussion care. Vision assessments in concussion must include smooth pursuits, saccades, near point of convergence (NPC), and accommodative amplitude (AA). A comprehensive, multidomain assessment is essential to predict prolonged recovery time and enable active intervention with specific school accommodations and targeted rehabilitation.

Vestibular patients generate more regular head movements than healthy individuals during gaze-stabilization exercises.

The vestibular system is vital for maintaining stable vision during daily activities. When peripheral vestibular input is lost, patients initially experience impaired gaze stability due to reduced effectiveness of the vestibular-ocular-reflex pathway. To aid rehabilitation, patients are often prescribed gaze-stabilization exercises during which they make self-initiated active head movements.

A growing literature suggests that declines in sensory/perceptual systems predate cognitive declines in aging, and furthermore, they are highly predictive for developing Alzheimer's disease and Alzheimer's related dementias (ADRD). While vision, hearing, olfaction, and vestibular function have each been shown to be related to ADRD, their causal relations to cognitive declines, how they interact with each other remains to be clarified. Currently, there is substantial debate whether sensory/perceptual systems that fail early in disease progression are causal in their contributions to cognitive load and/or social isolation or are simply coincident declines due to aging.

Objectives: Catch-up saccades help to compensate for loss of gaze stabilization during rapid head rotation in case of vestibular deficit. While overt saccades observed after head rotation are obviously visually guided, some of these catch-up saccades occur with shorter latency while the head is still moving, anticipating the needed final eye position. These covert saccades seem to be generated based on the integration of multisensory inputs.

The vestibular system is integral to behavior; the loss of peripheral vestibular function leads to disabling consequences, such as blurred vision, dizziness, and unstable posture, severely limiting activities of daily living. Fortunately, the vestibular system's well-defined peripheral structure and well-understood encoding strategies offer unique opportunities for developing sensory prostheses to restore vestibular function. While these devices show promising results in both animal models and implanted patients, substantial room for improvement remains.

A growing number of practitioners are implementing the Balance Tracking System (BTrackS) modified Clinical Test of Sensory Integration and Balance (mCTSIB) to evaluate the sensory sources of balance feedback used to maintain upright standing. The aim of the current study was to expand existing BTrackS mCTSIB normative databases on adults to include reference values from developmental age groups. Participants included children (age range = 5-8 years; n = 212), adolescents (age range = 9-12 years; n = 103), teenagers (age range = 13-17 years; n = 152), and young adults (age range = 18-29 years; n = 779).
