Sinus Bradycardia Localizes Where? (P1.129)
Discussion: Different possible mechanisms of autonomic dysfunction are discussed based on the anatomy of the lesions. Such mechanisms include sympathetic withdrawal due to a lesion of the descending sympathetic tract causing parasympathetic disinhibition, imbalance within the parasympathetic system itself, or disruption of the feedback circuits involving the parabrachial nucleus in the pons. It is also discussed whether laterality plays a role in the autonomic nervous system and whether compensatory mechanisms might take over in the subacute phase. This topic is of clinical interest as initial presentation with severe brad...

Association of the mtDNA m.4171C>A/MT-ND1 mutation with both optic neuropathy and bilateral brainstem lesions
Conclusion: This case widens the phenotypic expression of the rare m.4171C>A/MT-ND1 LHON mutation, which may also lead to Leigh-like brainstem lesions, and indicates that the co-occurrence of other ND non-synonymous variants, found outside of their usual mtDNA backgrounds, may have increased the pathogenic potential of the primary LHON mutation.

Cerebral large vessel vasculitis in systemic lupus erythematosus.
We report the case of a female patient with the diagnosis of SLE. She presented with stroke-like symptoms, headache and vertigo, and palpable purpura on her legs. Further investigations revealed that she suffered from both vasculitis of the cerebral large vessels and coexisting cutaneous small-vessel vasculitis.

Characteristics of CADASIL in Chinese mainland patients
Conclusions: Most characteristics of Chinese mainland CADASIL patients are similar to those of CADASIL patients living in other regions. However, the prevalence of primary intracerebral hemorrhage and vertigo is much higher in Chinese mainland CADASIL patients. Significant leukoaraiosis in anterior temporal poles on T2-weighted image are uncommon. Exons 3 and 4 are the mutation hotspots.

Diagnostic Value of S100B Protein in the Differential Diagnosis of Acute Vertigo in the Emergency Department / El Valor Diagnóstico de la Proteína S100B en el Diagnóstico Diferencial del Vértigo Agudo en el Servicio de Urgencias
ConclusionsTo the best of our knowledge this is the first study assessing the utility of serum S100B levels for diagnosis of acute‐onset vertigo. Serum S100B levels are associated with the presence of central causes of vertigo on cranial MRI. However, serum S100B levels are not sufficiently sensitive to exclude candidates from cranial MRI. Resumen ObjetivosEl vértigo es un motivo de consulta frecuente y es consecuencia de una etiología central o periférica. Debido a que las causas centrales pueden ser de riesgo vital, la determinación de la naturaleza del vértigo es crucial en el servicio de urgencias (SU). Con un ...

Subliminal galvanic-vestibular stimulation influences ego- and object-centred components of visual neglect
In conclusion, subliminal GVS modulates ego- and object-centred components of visual neglect rapidly. Implications for neurorehabilitation are discussed.

Quantifying the Vestibulo-Ocular Reflex with Video-Oculography: Nature and Frequency of Artifacts
This study systematically characterized the frequency, nature, and impact of artifacts on HIT VOR measures. From a prospective study of 26 patients with acute vestibular syndrome (16 vestibular neuritis, 10 stroke), we classified findings using a structured coding manual. Of 1,358 individual HIT traces, 72% had abnormal disruptive saccades, 44% had at least one artifact, and 42% were uninterpretable. Physicians using quantitative recording devices to measure head impulse VOR responses for clinical diagnosis should be aware of the potential impact of disruptive eye movements and measurement artifacts.Audiol Neurotol 2015;20:39-50

Acute peripheral vestibulopathy in a cocaine addict: Cracking the vestibular nucleus
A previously healthy 58-year-old man developed vertigo, imbalance, nausea, and vomiting shortly after smoking cocaine. He denied hearing loss, double vision, limb weakness, or sensory loss. Examination showed left-beating horizontal nystagmus with a torsional component, skew deviation, and positive right-sided head-impulse test. His urine tested positive for cocaine. Autoimmune workup, lipid panel, and echocardiography were unremarkable. MRI revealed acute right medial vestibular nucleus (VN) infarction (figure, A and B) and subcortical T2 hyperintensities (figure, C). Cerebral angiography was unremarkable. Presenting symp...

Psychiatric comorbidity and psychosocial impairment among patients with vertigo and dizziness
Conclusions Almost half of patients with vertigo/dizziness suffer from a psychiatric comorbidity. These patients show more severe psychosocial impairment compared with patients without psychiatric disorders. The worst combination, in terms of vertigo-related handicaps, is having non-organic vertigo/dizziness and psychiatric comorbidity. This phenomenon should be considered when diagnosing and treating vertigo/dizziness in the early stages of the disease.

Importance of spontaneous nystagmus detection in the differential diagnosis of acute vertigo
Publication date: March 2015 Source:Journal of Clinical Neuroscience, Volume 22, Issue 3 Author(s): Davor Pavlin-Premrl , John Waterston , Sean McGuigan , Bernard Infeld , Ron Sultana , Richard O’Sullivan , Richard P. Gerraty Vertigo is a common cause of emergency department attendance. Detection of spontaneous nystagmus may be a useful sign in distinguishing vestibular neuritis from other vestibular diagnoses. We aimed to assess the contribution of spontaneous nystagmus in the diagnosis of acute vertigo. We enrolled consecutive consenting patients arriving at a single emergency department with acute vertigo. There was...

Isolated central vestibular syndrome
Isolated vestibular syndrome may occur all along the vestibular pathways from the peripheral labyrinth to the brain. By virtue of recent developments in clinical neurotology and neuroimaging, however, diagnosis of isolated central vestibulopathy is increasing. Here, we review five distinct syndromes of isolated central vestibular syndrome from lesions restricted to the vestibular nuclei, the nucleus prepositus hypoglossi, the flocculus, the tonsil, and the nodulus, and introduce a new vestibular syndrome from isolated involvement of the inferior cerebellar peduncle. Decreased responses to head impulses do not exclude a cen...

STANDING, a four-step bedside algorithm for differential diagnosis of acute vertigo in the Emergency Department.
In conclusion, STANDING seems to be a promising simple structured bedside algorithm that in this preliminary study identified central AV with a very high sensitivity, and was associated with significant reduction of neuroimaging and hospitalisation rates.

Isolated Unilateral Ptosis due to Paramedian Midbrain Infarction
A 59-year-old man who had hypertension, dyslipidemia, diabetes mellitus, and left eye glaucoma developed sudden vertigo and left ptosis; he did not notice diplopia. He visited our hospital on day 3 after onset and neurologic examination showed left ptosis. His left visual acuity was counting fingers, and the light reflex was sluggish owing to glaucoma. Pupil sizes were equal, and eye movements and the lower lid were unremarkable. Magnetic resonance images revealed an acute infarction of the left paramedian midbrain.
