Summary
Dizziness is common in military personnel. Traumatic brain injury (TBI), with or without blast exposure, significantly increases dizziness risk. Blast exposure alone did not increase dizziness risk in this study.
Area of Science:
- Military health
- Neurology
- Epidemiology
Background:
- Dizziness is a common symptom with unknown prevalence in U.S. military populations.
- Dizziness is often linked to blast exposure and traumatic brain injury (TBI).
- Independent contributions of blast and TBI to dizziness require evaluation.
Purpose of the Study:
- Estimate dizziness prevalence in post-9/11 service members and Veterans.
- Examine associations between TBI history, blast exposure, and self-reported dizziness.
- Investigate independent and joint effects of TBI and blast exposure on dizziness.
Main Methods:
- Study included 424 service members and 492 Veterans from the NOISE Study.
- Logistic regression analyzed associations between TBI history, blast exposure, and dizziness.
- Models were stratified by service member/Veteran status and adjusted for confounders.
Main Results:
- Dizziness prevalence was 22% in service members and 31% in Veterans.
- TBI history (with or without blast) increased dizziness likelihood 3-4 times.
- Blast exposure without TBI history was not associated with increased dizziness.
Conclusions:
- Self-reported dizziness is prevalent in U.S. service members and Veterans.
- TBI history is independently associated with dizziness, regardless of blast exposure.
- Future research should focus on TBI pathophysiology for dizziness treatment strategies.

01:15Equilibrium and Balance
4.7K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.

IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular...

Tachyarrhythmias are a type of dysrhythmia where the heart rate exceeds 100 beats per minute. Here are some common types of tachyarrhythmias:Sinus TachycardiaSinus tachycardia originates from increased impulses from the sinus node, leading to an elevated heart rate. It is often triggered by stress, fever, or exercise.Patients may experience palpitations, a sensation of a racing heart, dizziness, and chest discomfort.Causes and Risk Factors: Common causes include physical exertion, emotional...

Generalized Anxiety Disorder (GAD) is a chronic condition characterized by excessive and uncontrollable worry that persists for at least six months, significantly interfering with daily functioning. Unlike situational anxiety, which arises in response to specific stressors, GAD often occurs without a clear cause. Individuals may experience disproportionate worry about work, health, or relationships. For instance, a person might continuously fear poor health despite normal medical evaluations or...

A thorough health history and physical assessment are essential for identifying cardiovascular disease (CVD) symptoms and distinguishing them from other health issues.
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities
