Labyrinthitis is an inner ear disorder in which a nerve that detects head movement becomes inflamed. Learn about the causes, symptoms, and treatment here. Dizziness is the feeling of being lightheaded, woozy, or unbalanced.
It can come about as a symptom of a number of conditions. Most underlying causes…. Health Conditions Discover Plan Connect. Another two cases have been described by Mat et al. With a more specific and instrumental study on 41 patients, Gallus et al. Furthermore, despite the cited studies, COVIDrelated BPPV has not been described in the literature, even if it is the most common cause of peripheral vestibular vertigo.
What is the exact cause of this relationship? Alternatively, in cases of more serious infection, with hospitalization and intensive care recovery, immobilization and prolonged bed rest could lead to the development of BPPV. Another hypothesis could be related to the endothelial dysfunction involving cerebral venous hemodynamics; this mechanism is extremely interesting and it was also described for sudden hearing loss [ 16 ]. Finally, similarly to what happens in the central nervous system often involved in COVID [ 17 ], a direct effect of viral infection on the peripheral vestibular system, namely the otolitic membrane, could justify the onset of vertigo.
In this topic, a direct cytopathic effect of the virus, an inflammatory response, a cytokine storm or a vascular event could be proposed as pathogenetic factors.
A final consideration concerns the unusually high proportion of horizontal canal involvement in our series compared to the typical distribution of BPPV subtypes. We found horizontal canal involvement in two out of three patients admitted to intensive care. As it is well known, these patients are often placed in pronation to improve oxygenation, and this forced position could modify the course of positional vertigo, justifying a greater incidence of forms involving the horizontal canal in our series.
In conclusion, further studies are necessary to investigate the effects of COVID, as well as for understanding long-term risks, on the vestibular system. In particular, studies on a large series of patients are needed to better evaluate the prevalence and pathophysiological mechanisms underlying BPPV in these patients.
The topics of future investigation can make use of instrumental techniques that allow for better study of the involvement of different components of vestibular system.

People with BPPV can experience a spinning sensation — vertigo — any time there is a change in the position of the head. The symptoms can be very distressing.
People can fall out of bed or lose their balance when they get up from bed and try to walk. If they tilt their head back or forward while walking, they may even fall, risking injury. Vertigo can cause the person to feel quite ill with nausea and vomiting. While the hallmark of BPPV is vertigo associated with changes in head position, many people with BPPV also feel a mild degree of unsteadiness in between their recurrent attacks of positional vertigo. The onset of BPPV may be abrupt and frightening.
People may think they are seriously ill; for example, they may fear they are having a stroke. Without treatment, the usual course of the illness is lessening of symptoms over a period of days to weeks, and sometimes there is spontaneous resolution of the condition.
In many people, especially older adults, there is no specific event that causes BPPV to occur, but there are some things that may bring on an attack:. Keeping the head in the same position for a long time, such as in the dentist chair, at the beauty salon or during strict bed rest.
Dix-Hallpike tests revealed a rapid onset of downbeat nystagmus with either ear down. The nystagmus was persistent, lasting more than one minute, unlike the characteristic nystagmus of canalithiasis.
Persistent horizontal apogeotropic nystagmus during supine roll testing has been reported in patients with cerebellar tumours particularly in the region of the fourth ventricle and nodule , anterior inferior cerebellar artery AICA and posterior inferior cerebellar artery PICA territory infarct, nodular infarct and medullary infarct Cho et al.
These patients presented similar to lateral cupulolithiasis but were not responsive to repositioning. In a study comparing horizontal apogeotropic CPN to horizontal apogeotropic nystagmus in BPV, it was found that the modulation of nystagmus between sitting and supine positions may be a useful point of differentiation.
Horizontal geotropic nystagmus upon supine roll testing has also been reported in patients with a cerebellar peduncle tumour and lateral medullary infarct Lee et al. Although AC-BPV may appear as downbeat nystagmus without a visible torsional component, its rarity should lower the threshold for seeking a central cause.
Lack of fatigability with repeat positioning and non-reversal of nystagmus when changing from supine to sitting for BPV of the vertical canals, or from lying on either side for LC-BPV, should raise the possibility of an alternative diagnosis.
Newly developed headaches and mismatch between the severity of vertigo and intensity of nystagmus should also raise the possibility of a central cause Lee et al. Failure to respond to multiple repositioning manoeuvres should prompt investigation for a central origin.
Horizontal apogeotropic and downbeat positional nystagmus are observed in less common BPV variants but often observed in central mimics, therefore merit particular attention Nuti et al. BPV is a frequently encountered cause of episodic vertigo in the neurology clinic and in primary care settings. In most cases, a diagnosis of BPV can be reached confidently with a typical history and careful examination of nystagmus during positional testing. Alternative diagnoses or comorbid conditions should always be considered when nystagmus patterns deviate from those of the most common BPV variants or persist after appropriate repositioning.

Abstract The diagnosis of benign positional vertigo BPV relies on a history of episodic positional vertigo and a distinctive pattern of nystagmus during provocative positional testing.
Keywords: Benign paroxysmal positional vertigo, Canalithiasis, Cupulolithiasis, Positional nystagmus. Introduction Benign positional vertigo BPV is a common and treatable peripheral vestibular disorder in which one or more of the semicircular canals are abnormally stimulated by otoconia displaced from the otolith organs.
Pathophysiology The semicircular canals are the sensors of angular head acceleration. Clinical history Rotational vertigo is the most common complaint of patients with BPV, which is expected given the involvement of the semicircular canals. Clinical examination The diagnosis of BPV relies on a typical history and provocative positional testing to elicit nystagmus in the plane of the affected canal.
Open in a separate window. The torsional component is described according to the movement of the upper pole of the eye. Table 2 Localising the affected ear in lateral canal BPV. Geotropic variant Apogeotropic variant Supine roll test Nuti et al. Treatment The treatment of BPV involves positional manoeuvres to direct the displaced otoconia back into the utricle. Orthostatic dizziness Orthostatic hypotension can present as episodic vertigo or dizziness in some patients however symptoms only occur upon arising from a lying or sitting position and are not due to changes in head position relative to gravity Bisdorff et al.
Acute vestibular loss with enhanced spontaneous nystagmus in the supine position Spontaneous vertigo can be aggravated by head movements however this is distinct from positional vertigo which is triggered by changes in head position. Vestibular migraine Although vertigo in vestibular migraine VM is typically spontaneous, positional vertigo can be a presenting symptom. Vestibular paroxysmia Vestibular paroxysmia is characterised by recurrent, brief attacks of vertigo lasting seconds to minutes.
Vestibular schwannoma Positional horizontal apogeotropic nystagmus has been described in cases of vestibular schwannoma and attributed to head movement causing further pressure on the vestibular nerve Hong et al. Central positional nystagmus Rarely, positional vertigo and nystagmus may be due to lesions affecting the brainstem and cerebellum. Conclusion BPV is a frequently encountered cause of episodic vertigo in the neurology clinic and in primary care settings.
