Visual Impairment

  • Light-headedness is nonspecific and hard to diagnose; it may result from panic attacks with hyperventilation. Investigations No investigations are likely to be performed in primary care.[patient.info]
  • Anxiety or panic attacks may also cause people to feel the sensation of vertigo. Stress may worsen symptoms, though it usually does not cause them.[emedicinehealth.com]
  • Patients who experience anxiety or panic attacks can have vertigo as a result of hyperventilation. 8 Loud noises can precipitate vertigo in patients with peripheral causes in a phenomenon called Tullio phenomenon. 9 Medications, including frusemide, salicylates[racgp.org.au]

Nystagmus
  • The first case had combined torsional and horizontal nystagmus to the right in a head-hanging position. The nystagmus lacked latency and did not diminish easily.[jstage.jst.go.jp]
  • Ageotropic positional nystagmus appears with the head turned to the right in the supine position (top). The nystagmus changes direction as soon as the head is rolled toward the opposite side (bottom).[stroke.ahajournals.org]

Prognosis

  • The main differential diagnosis of CPPV is benign paroxysmal positional vertigo (BPPV), and given the potentially serious prognosis of infratentorial lesions, this is a critical distinction.[scholars.opb.msu.edu]
  • What Is Vertigo Prognosis? The prognosis depends on the source of the vertigo. Vertigo caused by problems in the inner ear, while usually self-limited, in some cases can become completely incapacitating.[emedicinehealth.com]
  • Prognosis Most cases of vertigo last a few hours to a few days. Symptoms caused by acute labyrinthitis almost always go away without permanent injury. Other causes of vertigo may result in symptoms that are more persistent.[drugs.com]
  • Prognosis Follow-up studies have shown BPPV recurrence rates of 50% at five years and a persistence of dizziness related to anxiety in almost a third of patients one year after vestibular neuritis [ 4 ] .[patient.info]

Etiology

  • The causes of vertigo are numerous, yet are most often categorized as being either of peripheral or central etiology.[emlyceum.com]
  • Therefore, a dangerous HINTS exam should carry a high clinical suspicion for central etiologies even in the setting of a negative MRI within the first 2 days.[ebmconsult.com]
  • ., labrynth, vestibular nerve, vestibular nuclei, and cerebellum can be divided into peripheral vertigo central vertigo Peripheral vertigo describes vertigo caused by lesions affecting the inner ear and cranial nerve VIII (vestibulocochlear nerve) etiologies[medbullets.com]
  • Vertigo is a frequent symptom that results from a variety of etiologies, some benign and others serious. One of the more important differentiating features is determining if the vertigo has a peripheral or central etiology.[casemed.case.edu]
  • An Arnold-Chiari type I malformation, in which the cerebellar tonsils herniate through the foramen magnum and compress the brainstem and spinal cord, is the most common structural etiology ( Fig 9-2 ).[aao.org]

Pathophysiology

  • Interest in BPPV is increasing because its underlying pathophysiology was clarified recently. 4–6 Small cerebellar hemorrhage, especially around the vermis, sometimes causes isolated dizziness symptoms with positional nystagmus similar to that of BPPV[stroke.ahajournals.org]
  • The presumed pathophysiology for the upbeating nystagmus is thought to be the opposite of that for the downbeating nystagmus.[mhmedical.com]
  • However, it does not mean that we cannot narrow down our diagnoses; by the existence of postulated hypothesis for the pathophysiology of nystagmus, we can somehow localize the lesion.[teddybrain.wordpress.com]
  • The technique is based on the assumption that the pathophysiological mechanism of antBPPV is similar to that generating posterior canal canalolithiasis. The patients recovered from refractory antBPPV after one or more PFPPs.[jnnp.bmj.com]
  • The first attack usually occurs in patients aged 65 and older, but in rare instances begins during childhood. 5 The pathophysiology of Ménière’s disease is poorly understood.[emsworld.com]
