Vertebral artery thrombosis in a 7-year-old child
We present the case history of a 7-year-old boy who was admitted to the pediatric intensive care unit of a county hospital with symptoms of facial palsy, progrediating ataxia and somnolence. Contrast-enhanced angiographic MR images of the skull revealed acute ischemic lesions and suggested stenosis of the left vertebral artery, then it was confirmed by TOF (time of flight) angiography of vessels of the neck and cervical ultrasound examination. The arterial thrombus causing ischaemia was eliminated by drug treatment and the rehabilitation process could be started. The patient's condition improved considerably following that...

Heterogeneous phenotypic manifestations of maternally inherited deafness associated with the mitochondrial A3243G mutation. Case report.
Abstract The A3243G mutation is one of the most frequent mutations of mitochondrial DNA. The phenotypic expression of the A3243G mutation is variable and causes a wide range of syndromic and non-syndromic clinical disorders. Mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes (MELAS) syndrome is the most frequent syndromic manifestation of the A3243G mutation. Stroke-like episodes seem to be the dominant feature of MELAS. We have investigated the case of a family with A3243G mutation, in which a dominant symptom in three generations was the maternally inherited hearing loss with absenc...

Central Nervous System Complications of Varicella-Zoster Virus
Conclusion: Neurologic complications of VZV infection continue to occur despite the availability of an effective vaccine. Neurologic symptom onset can predate the appearance of the VZV exanthem and in rare cases may occur in the absence of an exanthem.

Symptoms of transient ischemic attack.
Authors: Kim JS Abstract Transient ischemic attack (TIA) is a cerebrovascular disease with temporary (<24 h) neurological symptoms. The symptoms of TIA patients are largely similar to those of ischemic stroke patients and include unilateral limb weakness, speech disturbances, sensory symptoms, visual disturbances, and gait difficulties. As these symptoms are transient, they are frequently evaluated based on patients' subjective reports, which are less precise than those of patients with stroke whose longer-lasting symptoms and signs can be reliably assessed by physicians. Some symptoms, such as monocular blindne...

Spontaneous vertebral artery dissection with thunderclap headache: a case report and review of the literature.
CONCLUSION: The most common neuroimaging findings of VAD were vertebral artery stenosis, followed by the string and pearls sign, arterial dilation, arterial occlusion, and the less common but most characteristic features of pseudoaneurysm formation, double lumen, and intimal flap. Pain in VAD mostly occurred in the ipsilateral posterior occipitonuchal region, with throbbing features in 50- 60% of the patients. Only one fifth of patients with VAD present with a thunderclap pattern. In stroke among young patients or stroke with pain in the head and neck, angiography study of the craniocervical artery is highly recommended. ...

The Clinical and Imaging Profile of Skew Deviation: A Study of 157 Cases
Conclusions: The amplitude of misalignment in skew deviation varies widely but is generally 5 PD or less. When misalignment is 3 PD or less, patients report blurred vision rather than diplopia. Skew deviation is usually accompanied by other neurologic signs reflecting brainstem dysfunction. Yet there is a small subgroup in which vertical misalignment is an isolated sign, and there are no supporting brain imaging abnormalities. The main cause of skew deviation is ischemic stroke, which affects not only the brainstem but also the thalamus. Diplopia from skew deviation frequently persists, in which case prism spectacles m...

E-248 Postpartum vertebral artery dissections: a report of 7 cases and literature review
ConclusionA limited cohort of 33 ppVADs exist in the literature. This study contributes 7 additional cases and suggests that, despite heterogenous management of ppVAD, the resulting outcomes were favorable.Disclosures V. Lazarov: None. A. Monteiro: None. F.

Video head impulse testing in patients with isolated (hemi)nodular infarction
ConclusionsUsing quantitative, video-based testing of the horizontal and vertical aVOR, preserved integrity of the aVOR in (hemi)nodular strokes was confirmed, extending preliminary findings at the bedside. Furthermore, widespread deficits of both ocular stability, postural control and volitional eye movements were observed in our study cohort, being consistent with findings reported in previous studies.

Poststroke spasticity: Treating to the disability
People who have strokes are subject to numerous potentially devastating sequelae, most often sensorimotor paresis, impairment of cognition and language, and other functional disabilities, including depression and dementia. Of these sequelae, spasticity occurring with motor dysfunction is a frequent finding that has to be evaluated in light of other diagnoses, such as central paresis, ataxia, pathologic stance or gait, and other coordination dysfunctions. Often, spasticity is not notably present in acute ischemic strokes but develops later on, and may then become a major obstacle for achieving independence in performance of...

Cerebellar Allocentric and Action-Intentional Spatial Neglect (P01.003)
CONCLUSIONS: The patient's clock drawing and figure drawing errors have been previous described in a patient with cortical dysfunction and this action-intentional neglect is thought to be a form of an action-intentional grasp induced by frontal dysfunction. Alternatively, right hemisphere dysfunction could cause a deficit in global attention, and when performing a focal attentional task of placing and writing clock numbers, she became unaware of the global form on the left side.Disclosure: Dr. Milano has nothing to disclose.

Phenotypic variability in ARCA2 and identification of a core ataxic phenotype with slow progression
We report here the clinical and molecular data of 10 newly diagnosed patients from seven families and update the disease history of four additional patients reported in previous articles to delineate the clinical spectrum of ARCA2 phenotype and to provide a guide to the molecular diagnosis. First signs occurred before adulthood in all 14 patients. Cerebellar atrophy appeared in all instances. The progressivity and severity of ataxia varied greatly, but no patients had the typical inexorable ataxic course that characterizes other childhood-onset recessive ataxias. The ataxia was frequently associated with other neurological...

Spinning Out of Control: The Black Box of Basilar and Hemiplegic Migraine (P7.176)
CONCLUSIONS:In this retrospective study, triptans were used effectively with no subsequent vascular events for the abortive treatment of migraines with basilar and hemiplegic features. This data also suggests that beta blockers, tricyclic anti-depressants, anti-convulsants, and Botox injections have some efficacy in the treatment of migraines with basilar type and hemiplegic features.Disclosure: Dr. Krel has nothing to disclose.

Immunocompetent pml--an immunological scotoma?
We describe two cases of progressive multifocal leucoencephalopathy (PML) presenting as stroke in the immunocompetent. A 73-year-old man with a background of treated prostate carcinoma presented in October 2013 with a right hemiplegia; a diagnosis of lacunar infarction was made following CT. However, he progressed with increasing pyramidal weakness, ataxia, dysphasia and dysarthria. MRI in December revealed confluent T2 and FLAIR hyperintense white matter change with normal DWI. Extensive infective, vasculitic and malignancy screen were unremarkable; PCR in serum and CSF demonstrated JC virus DNA. Unfortunately the patient...

Autism in the Son of a Woman with Mitochondrial Myopathy and Dysautonomia: A Case Report
Conclusion Given emerging evidence that mitochondrial dysfunction, particularly in the electron transport chain needed for cellular energy production, is an underlying pathophysiological mechanism for some varieties of ASD, clinicians should have a high index of suspicion for mitochondrial disease, especially when they encounter a patient with unusual neurological or constitutional symptoms. The prevalence of mitochondrial disease in ASD patients may be as high as five percent, which means that it is not the “zebra”[27] diagnosis that it might be in a non-ASD patient, where prevalence is about 0.01 percent.10 Reference...
