Emergency Department Visits for Mild Traumatic Brain Injury: Associations with Geriatric Age, Sex, and Fall Injury.

PURPOSE: The highest rates mTBI occurrence are seen among geriatric populations (ages ≥65), and these patients often have persistent and untreated symptoms. This study's purpose was to explore mild traumatic brain injury initial onset (mTBI-IN) and mild traumatic brain injury subsequent (mTBI-S) emergency department (ED) visit population percentages and associations with geriatric (population ages ≥65), sex, and fall mechanism of injury. METHODS: The design was a population-based cross-sectional study using data from the 2018 Nationwide Emergency Department Sample (NEDS). Study sample size was 261,349. An independent t-test was used to investigate mean age differences between mTBI-IN and mTBI-S. Pearson's chi-squared correlational analyses were used to investigate associations of age, sex, and fall injury with mTBI-IN and mTBI-S. RESULTS: The mean age of those in 2018 with ED visits suggested that age was older for those patients with mTBI-S (age mean, 50.4 yrs) than those with mTBI-IN (age mean, 41.4 yrs) (95% CI 9.77, 8.30; p=0.025). The number of visits for those aged ≥65 was significantly associated with mTBI-S (p<0.001). More males than females reported mTBI-S ED visits in all ages (p=0.022). Falls injury alone was not found to be significantly associated with visits (p<0.001). CONCLUSIONS: Those returning to the ED for continued care after mTBI were associated with those aged ≥65. Monitoring after mTBI ED visits may need to target geriatric populations for medical management.

Differential screen and treatment of vestibular dysfunction in an elderly patient: A case report.

BACKGROUND/PURPOSE: Concussion sequelae in the elderly is under recognized and negatively impacts quality of life. Labyrinthine concussion (LC) is an uncommon diagnosis, as is multiple canal (MC) benign paroxysmal positional vertigo (BPPV). This case report highlights physical therapist (PT) evaluation and treatment of an elderly male misdiagnosed with LC and successfully treated for MC BPPV. CASE DESCRIPTION: A 72 year old male presented to his PT 23 days after falling off a ladder, resulting in a mild traumatic brain injury (mTBI). Diagnosed with LC, he was referred to PT due to ongoing symptoms of "falling backwards," poor gait, and diminished mobility. PT examination revealed an atypical BPPV. Thus, the patient was treated in two PT visits, which included canalith repositioning techniques and neuromuscular reeducation. OUTCOMES: The PT diagnosis was MC BPPV, including the right lateral and left posterior semicircular canals. Initial positive findings of Head Impulse Test, Bow and Lean Test, Dix-Hallpike, and Roll Test were negative on the last visit. Patient-Specific Functional Scale improved from 0 to 9.9 (10 being no limitations). The patient progressed from minimum assistance to independence in bed mobility, transfers, gait, and previous activities. DISCUSSION: The patient's presentation was atypical in signs and symptoms with a diagnosis of LC. PT examination and intervention successfully resolved the patient's signs and symptoms within two visits. Further research is needed regarding identification and treatment of elderly individuals with head injuries, such as MC BPPV, as well as the efficacy of a PT seeing patients shortly after mTBI.
