• Anemia

  Diagnosis of BPPV Diagnosing BPPV is a matter of ruling out other symptoms that may cause vertigo: migraines stroke blood flow caused by anemia low blood sugar hyperventilation dehydration heart problems These conditions that mimic BPPV can be ruled out [hearingcentral.com]

  There are many other conditions that may be responsible including ear infections, neurological disorders, anemia, inner ear abnormalities and more. [centraloregonaudiology.com]

  For example anemia and low blood sugar are known to cause dizziness. This should be differentiated from vertigo. Audiometry tests are performed to detect Ménière’s disease. An audiometer produces sounds of different volume and pitch. [news-medical.net]

  Orthostatic hypotension (sharp decrease in blood pressure upon rising from a lying or sitting position to a standing position may be caused by diabetes, dehydration, and anemia). [raysahelian.com]

  It is sometimes seen in patients with inadequate cardiac (heart) function or with anemia. Certain drugs also decrease the blood flow to the brain, especially stimulants such as nicotine and caffeine. [ccent.com]

• Hearing Problem

  problems in addition to vertigo then referral should be made to an ENT specialist. [bjmp.org]

  Basic audiological examination ( table 2 ) revealed that few patients had evidence suggesting conduction hearing problems. Normal middle ear status was confirmed by otoscopy and standard aural immittance procedures. [jneuro.com]

• Muscle Weakness

  Neurological symptoms - eg, headache, diplopia, visual disturbance, dysarthria or dysphagia, paraesthesia, muscle weakness or ataxia. Autonomic symptoms - eg, nausea and vomiting, sweating or palpitations. [patient.info]

  Pathological gaze evoked nystagmus may be attributable to a peripheral process, 2 being a sign of extraocular muscle weakness, for example, in patients with myasthenia gravis (“fatigue nystagmus”). [jnnp.bmj.com]

  Apparent risk factors for cervicogenic dizziness include head trauma, neck trauma (commonly whiplash), peripheral vestibular dysfunction, and focal paraspinal muscle weakness. [clevelandclinicmeded.com]

• Osteoporosis

  We also identified the comorbidities of the patients with BPPV, including head trauma, osteoporosis, migraine, hypertension, diabetes, hyperlipidemia and stroke. These variables were then compared to those in age- and gender-matched controls. [journals.plos.org]

  Osteoporosis is a risk factor for the recurrence of benign paroxysmal positional vertigo. BPPV is a common cause of severe dizziness. [raysahelian.com]

  For older patients, patients with neuromuscular and joint disorders, patients with osteoporosis at risk for fragility fracture, it is recommended that an assessment for gait and fall risk is performed prior to discharge. [clinicaladvisor.com]

• Photophobia

  Patients with migrainous vertigo may experience other symptoms related to the migraine, including a typical headache (often throbbing, unilateral, sometimes preceded by an aura), nausea, vomiting, photophobia, and phonophobia. [aafp.org]

  In the classic migraine or migraine with aura (MA), headache is preceded by transient neurological symptoms as photophobia and phonophobia ( 3 ). [jneuro.com]

  Other symptoms of migraine headache include photophobia (increased sensitivity to light), phonophobia (increased sensitivity to sound), nausea and vomiting. [emsworld.com]

  An ocular examination should be performed with the best age dependant equipment available specifically looking for signs of photophobia, retinal dystrophy, retinal/choroidal hypopigmentation, iris transillumination and anterior segment anomaly e.g., cataract [nature.com]

• Nystagmus

  Acta Otolaryngol (Stockh) (in press) Google Scholar Büttner U, Brandt Th, Helmchen Ch (1999) The direction of nystagmus is important for the diagnosis of central paroxysmal positioning nystagmus (cPPV). [link.springer.com]

  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]

  […] and habituation on repetitive stimulation, positional or positioning nystagmus without vertigo, positioning-induced vomiting without nystagmus, and additional cerebellar and oculomotor signs. [scholars.opb.msu.edu]

  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]

• Cerebellar Disease

  Rebound Nystagmus • Rebound is nearly always pathological, and is related to brain stem or cerebellar disease • Pontine ischemia, brainstem MS, lesions of the cerebellar floccus, degenerative cerebellar disease • Evoked patient follow ones finger to one [slideshare.net]

  It is seen in patients with cerebellar disease (particularly the flocculus), muscle palsy and drug toxicity. [ncbi.nlm.nih.gov]

  Acute cerebellar disease Loss of balance and difficulty maintaining posture, standing, and walking suggest cerebellar disease. [emedicine.medscape.com]

  However, cerebellar disease that causes PAN also impairs these “compensatory mechanisms”. Normal results in the vHIT precluded more examinations as there is convincing evidence of normal peripheral vestibular function. [elsevier.es]

  None of the patients had bilateral canal paresis. Canal paresis was detected on the affected side in 13 patients in both caloric tests and in 6 patients only in the first test. [bmcophthalmol.biomedcentral.com]

  The range is so broad because the studies use different inclusion and exclusion criteria; they compare the results against a variety of other tests; and they use different ENG criteria for canal paresis. [dizziness-and-balance.com]

  A one-and-a-half syndrome is a caused by a lesion to either the sixth-nerve nucleus or the PPRF (or both) and the MLF, resulting in an ipsilateral conjugate gaze paresis and an ipsilateral INO. [ajnr.org]

  Clinical examination between the attacks may reveal signs of permanent vestibular deficit, hypoacusis or facial paresis on the affected side [ 97, 98 ]. Mild vestibular deficits can be found with caloric testing in about 70% of the patients [ 96 ]. [onlinelibrary.wiley.com]

• Perseveration

  Often, when a dizzy patient presents we perseverate on characterizes what the patient means by “dizzy.” [foamcast.org]

  Occipital lobe lesions may also result in palinopsia, or a perseveration of the visual image once the stimulus has been removed. [ajnr.org]

  In general, the mechanism for perverted HSN is thought to be either a directional error in the input circuitry, or a directional error in the central velocity storage mechanism that perseverates vestibular input. [dizziness-and-balance.com]

• Excitement

  In its general form it states that excitation is a relatively better vestibular stimulus than is inhibition (Leigh and Zee 2006). [dizziness-and-balance.com]

  The stipulated mechanism of action is an increase in the resting activity and excitability of Purkinje cells; this was confirmed by in-vitro studies ( 14 ). [ncbi.nlm.nih.gov]

  In addition, excitability changes in visual, parietal and temporal cortices were also observed with transcranial magnetic stimulations (TMS) ( 29, 34 ). [jneuro.com]

Long-tract findings such as weakness, hyperesthesia, or positive Babinski sign are ominous and mandate further workup. Ataxia may be the most important indicator of cerebellar disease. [emedicine.medscape.com]

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]

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]

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]
