Summary
Coronavirus disease 2019 (COVID-19) can cause vestibular neuritis, a condition affecting balance. This case study shows persistent symptoms and autonomic dysfunction following COVID-19 recovery.
Area of Science:
- Neurology
- Otolaryngology
- Infectious Diseases
Background:
- The pathophysiology of coronavirus disease 2019 (COVID-19) is not fully understood.
- COVID-19 has been anecdotally linked to neurological symptoms, including dizziness and vertigo.
Observation:
- A 57-year-old man developed rotational vertigo and dizziness after COVID-19 infection.
- Symptoms worsened with neck rotation, and initial tests suggested right superior vestibular neuritis.
Findings:
- Video head impulse test (vHIT) and ocular vestibular evoked myogenic potential (oVEMP) confirmed vestibular neuritis.
- While vestibular function improved over seven months, persistent postural instability and orthostatic hypotension indicated autonomic nervous system dysfunction.
Implications:
- This case suggests COVID-19 may have long-term effects on the vestibular system.
- Further research is needed to understand the mechanisms of COVID-19-related vestibular and autonomic dysfunction.

01:15Equilibrium and Balance
5.1K
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...

01:29The Vestibular System
40.2K
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.

The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
