Diagnosis of dizziness in the emergency department: A 1-year prospective single-center study
CONCLUSION: There is a substantial rate of misdiagnosis in patients with dizziness caused by VBS in the ED. To reduce the number of missing diagnoses of VBS in the future, there is a need to train emergency physicians in neurovestibular examinations, including the HINTS examination for acute vestibular syndrome (AVS) and the Dix-Hallpike (DH) maneuver for episodic vestibular syndrome. Using video head impulse test could help reduce the rate of misdiagnosis of VBS in the ED.PMID:36911955 | DOI:10.3233/VES-220109

ECG for Eyes Sorts Strokes from Vertigo (CME/CE)
(MedPage Today) -- A device described as an ECG for the eye accurately distinguishes stroke from other causes of dizziness in the emergency department, a small proof-of-concept study showed.

Clinical Study of Medial Area Infarction in the Region of Posterior Inferior Cerebellar Artery
Our objective is to study the neurological characteristics of medial area infarction in the caudal cerebellum. Medial area of the caudal cerebellum is supplied with 2 branches of the posterior inferior cerebellar artery (PICA). The medial hemispheric branch of the PICA distributes to the medial area of the caudal cerebellar hemisphere. The medial branch of the PICA (mPICA) distributes to the inferior vermis. We studied the neurological characteristics of 18 patients with medial area infarction of the caudal cerebellum. The infarction was located in the medial area of the cerebellar hemisphere and vermis (medial ch/vermis) ...

Emergency room decision-making for urgent cranial computed tomography: selection criteria for subsets of non-trauma patients.
CONCLUSION: Although 100% sensitivity was not achieved, our results may contribute to the evidence that in the absence of focal neurologic deficit, headache with vomiting or altered mental status in patients aged <60 years cranial tomography can be refrained from, in the general population as well as in the subgroup defined above. Further research might validate patient history as a parameter. PMID: 24060816 [PubMed - as supplied by publisher]

Basilar Artery Thrombus vs. Fenestration: A Differential Diagnostic Challenge in Acute Ischemic Stroke
We present a case of a man presenting with vertigo and nausea who was found to have multifocal infarcts in the posterior circulation on magnetic resonance imaging (MRI). An magnetic resonance angiography (MRA) demonstrated focal widening and central signal dropout in the distal vertebral artery consistent with arterial fenestration. Transcranial Doppler ultrasonography showed turbulent flow and a spike waveform suggestive of an intra‐luminal thrombus. This was confirmed by computed tomography (CT) angiography. Following the initiation of dual antiplatelet therapy, the signal abnormalities on transcranial doppler (TCD) re...

Serendipitous Recanalization of Basilar Artery Occlusion
Conclusions: Tenecteplase has enhanced biochemical and pharmacokinetic properties that may be ideal for treatment of basilar artery occlusion and should be further investigated in a randomized clinical trial.

Ipsilateral Sensorimotor Deficits in Lateral Medullary Infarction: A Case Report
The patient, a 32-year-old man, presented with sudden onset of occipital headache, vertigo, dysarthria, gait ataxia, right Horner syndrome, numbness of the right hand, and mild right hemiparesis. On magnetic resonance imaging, an acute small infarction was located on the right side of the caudal medulla extending dorsomedially. Magnetic resonance angiography showed severe right vertebral artery stenosis. Lateral medullary infarction associated with ipsilateral sensorimotor deficits in the limb is very rare, and the lesion probably involved the ipsilateral dorsal column or decussating lemniscal fibers and corticospinal fibe...

Memantine for Lewy Body Disorders: Systematic Review and Meta-Analysis.
CONCLUSION: Our results suggest that memantine did not have a benefit for the treatment of Lewy body disorders in cognition and motor function. However, memantine may be superior to placebo for the overall impression of the disorders. Further, memantine is well tolerated. PMID: 24406251 [PubMed - as supplied by publisher]

What Causes Ataxia?
Discussion Coordination and balance problems are caused by various problems affecting the central and peripheral nervous system. Normal development of a child or weakness of a child are commonly mistaken for true ataxia. Ataxia specifically refers to “…impairment of the coordination of movement without loss of muscle strength.” If it is purely due to abnormalities of the cerebellum then there should be no changes in mental status, sensation or weakness. Sometimes it is difficult to determine if there are abnormalities in other areas. For example, Guillian-Barre often presents with difficulty or clumsy wal...
