Summary
Traumatic brain injury (TBI) and behavioral health (BH) conditions in service members often involve vestibular issues. Oculomotor tests, especially vertical saccades and pursuit, are key for detecting neurological changes in TBI patients.
Area of Science:
- Neuroscience
- Audiology
- Military Medicine
Background:
- The National Intrepid Center of Excellence (NICoE) addresses traumatic brain injury (TBI) and comorbid behavioral health (BH) conditions in service members.
- Vestibular symptoms are common in this population, but test results vary.
- Comprehensive vestibular assessment is part of the NICoE intensive outpatient program.
Purpose of the Study:
- To analyze vestibular test results from NICoE patients.
- To identify specific vestibular tests frequently abnormal in service members with TBI and BH conditions.
Main Methods:
- Retrospective analysis of vestibular test results from a sample of NICoE patients.
- Focus on interdisciplinary evaluations including comprehensive vestibular assessment.
Main Results:
- Oculomotor tests, specifically pursuit and saccade tests, showed the highest rates of abnormality.
- Vertical subtests of pursuit and saccade tests were more frequently abnormal than horizontal subtests.
- Abnormalities were noted in tests of central vestibular function.
Conclusions:
- Vertical oculomotor subtests (pursuit and saccades) are valuable for evaluating TBI patients.
- Oculomotor and central vestibular function tests can detect neurological changes in active duty service members with chronic TBI symptoms.

01:29The Vestibular System
44.0K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

02:04Conservation of Small Populations
17.4K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

01:25What is Population Genetics?
65.0K
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

00:57Population Growth
28.7K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

00:58Sound Intensity
4.9K
The loudness of a sound source is related to how energetically the source is vibrating, consequently making the molecules of the propagation medium vibrate. To measure the loudness of a source, the physical quantity of interest is the intensity. This is defined as the energy emitted per unit of time per unit of area perpendicular to the sound wave's propagation direction. Since the total energy is greater if the source vibrates for a longer duration and over a larger area, dividing the...
