Vestibular disorders following head injury in children
Insights
Blunt head injuries in children frequently cause objective vestibular lesions, such as nystagmus and ENG disturbances, that persist long-term. However, these objective findings are often not accompanied by subjective symptoms like vertigo.
Area of Science:
- Neurology
- Pediatrics
- Ophthalmology
Background:
- Blunt head injuries can impact neurological and vestibular function.
- Vestibular disturbances following head trauma are common in adults, but less is known about their long-term effects in children.
- Objective and subjective symptoms of vestibular dysfunction require careful evaluation after pediatric head trauma.
Purpose of the Study:
- To investigate the prevalence and persistence of objective and subjective vestibular lesions in children following blunt head injury.
- To compare the incidence of vestibular disturbances in children with those reported in adult populations.
- To assess the correlation between objective vestibular findings and subjective symptoms like vertigo.
Main Methods:
- Examination of 199 child patients with blunt head injury.
- Assessment of spontaneous and/or positional nystagmus (≥7 degrees/s) at various time points post-trauma.
- Evaluation of central electro-nystagmography (ENG) disturbances at different intervals after injury.
- Inquiry into the presence and duration of subjective vertigo symptoms.
Main Results:
- Immediately after trauma, 46% of children exhibited nystagmus and 43% showed central ENG disturbances.
- Vestibular abnormalities persisted over time: 20% had nystagmus at 6-12 months and 18% at 2-8 years; ENG disturbances were found in 24% at 6-12 months and 12% at 2-8 years.
- Only 1.5% of child patients reported vertigo lasting longer than 6 months post-trauma.
Conclusions:
- Blunt head injuries induce objective vestibular lesions in children, comparable in frequency to adults.
- Children with head injuries exhibit fewer subjective symptoms (vertigo) than objective vestibular impairments.
- Long-term monitoring reveals persistent objective vestibular dysfunction after pediatric head trauma, often without significant subjective complaints.
Abstract:
One hundred and ninety-nine child patients with blunt head injury were examined. Spontaneous and/or positional nystagmus (greater than or equal to 7 degrees/s) was observed immediately after trauma in 46% of cases, 6-12 months (average 10.2 months) later in 20%, and 2-8 years (average 4.7 years) later in 18%. Central ENG disturbances were found immediately after trauma in 43% of cases, 6-12 months later in 24%, and 2-8 years later in 12%. Only 1.5% of the child patients suffered from vertigo more than 6 months after trauma. The results of the study led to the conclusion that head injuries cause about as many similar objective vestibular lesions in children as in adults but fewer subjective symptoms.
