Misdiagnosis of CADASIL: A single Medical Center experience (P1.251)
Conclusions:CADASIL is the most prevalent monogenic cerebral small-vessel arteriopathy. Despite wide availability of genetic testing, misdiagnosis and delay diagnosis are common. We encourage for enhanced awareness of CADASIL among patients with migraines with aura, recurrent TIAs or subcortical ischemic strokes, and mood disorder, in order to provide appropriate multidisciplinary treatment, psychological support and genetic counselingStudy Supported by: n/aDisclosure: Dr. Ortiz-Garcia has nothing to disclose.

Common etiologies of acute symptomatic seizures evolving from lateralized periodic discharges in patients monitored with continuous EEG (P2.233)
Conclusions:The most common high risk etiologies of acute symptomatic seizures evolving from lateralized periodic discharges in our cohort of patients were ischemic stroke, tumor, encephalitis, and subdural hematoma. Recognition of these etiologic factors may influence the duration of continuous EEG monitoring employed or the decision to institute seizure prophylaxis. A larger cohort of patients should be reviewed in a future study to confirm these findings.Disclosure: Dr. Mathew has nothing to disclose. Dr. Piran has nothing to disclose.

Sporadic Creutzfeldt-Jakob Disease Presenting as Non-Convulsive Status Epilepticus: A Case Report (P1.333)
CONCLUSIONS: Non-convulsive status epilepticus is an extremely rare presentation of prion disease. To date, there have only been three reported cases in the literature. This case highlights the need to consider prion disease as an etiology in NCSE and NORSE.Disclosure: Dr. Alobaidy has nothing to disclose. Dr. Parker has nothing to disclose.

Acute Diffusion-Weighted MRI Abnormalities in Status Epilepticus (P4.190)
Conclusions: Our findings revealed that the abnormality on diffusion-weighted MRI and residual brain atrophy in status epilepticus is more frequent than previous study. These abnormalities may reflect the epileptogenic hyperexcitation and propagation of ictal discharge.Disclosure: Dr. Son has nothing to disclose.

Predictors of Poor Outcome in Neuroleptic Malignant Syndrome: Retrospective Analysis of Nationwide Inpatient Sample (S32.006)
CONCLUSIONS: In patients admitted for neuroleptic malignant syndrome, every decade increment in age, acute kidney injury, seizures and respiratory failure were positive predictors of poor outcome. Every calendar year increase was a negative predictor of poor outcome. Study Supported by:Disclosure: Dr. Modi has nothing to disclose. Dr. Dharaiya has nothing to disclose.

Limbic Encephalitis Exacerbations and Remissions Charted by Microglial PET Scan: A Case Study (P4.104)
CONCLUSIONS: C-11-PK11195 PET imaging can be useful in the diagnosis of limbic encephalitis and for monitoring response to treatment. MALT lymphoma may also be associated with autoimmune or paraneoplastic encephalitis, especially in individuals with other predisposing factors to autoimmune disorders, such as Tourette’s and autoimmune thyroid disease. The reduction in microglial activity with both IVIG and anti-psychotics supports previous findings that anti-psychotics may act through anti-inflammatory pathways.Disclosure: Dr. Shatz has received research support from Janssen Pharmaceutica.

Mitochondrial Encephalopathy with Lactic Acidosis and Stroke (MELAS) presenting as an apparent neoplastic process (P5.015)
CONCLUSION: MELAS can mimic more common disorders. The slow onset of her symptoms and the MRI's appearance led to suspicion for neoplasm. This is the first report to our knowledge where MELAS has presented as such. Documentation of this and other unusual presentations of mitochondrial disease is crucial to appropriate diagnosis of the condition.Disclosure: Dr. Rothstein has nothing to disclose.

Inferior Cerebellar Peduncular Lesion Causes a Distinct Vestibular Syndrome (P1.332)
CONCLUSIONS: Unilateral ICP lesion at the pontine level mimics acute peripheral vestibular disorders. However, directional dissociation between OTR/SVV tilt and body lateropulsion with normal head impulse or caloric tests may be a sign distinguishing lesions involving unilateral ICP at the pontine level from those affecting other vestibular structures.

The Role of Toll-Like Receptor 3 in Epileptogenesis (S29.002)
Conclusion:These preliminary results -in a still ongoing study- indicate a central involvement of seizure induction (epileptogenesis) by TLR3 and provide evidence for future research and possibly drug development to finally change the treatment paradigm of epilepsy from symptomatic seizure control to curable prevention of seizure development.Disclosure: Dr. Benninger has nothing to disclose.

NeurologicManifestations of Neglected Tropical Diseases (P4.295)
CONCLUSIONS: Neurological manifestations of NTDs cause significant morbidity and mortality, although data are limited. The evidence for treatments of neurologic complications is limited for most NTDs. Increased awareness of neurologic manifestations of NTDs can promote early identification and treatment, thereby contributing to ongoing elimination and eradication campaigns.Study Supported by: NADisclosure: Dr. Raibagkar has nothing to disclose.

Voltage Gated Calcium Channels Antibody-Associated Autoimmune Encephalitis (P5.228)
ConclusionThis case demonstrates a correlation between a high titer of VGCC antibodies and autoimmune encephalitis. Our patient's initial improvement with steroids and plasma exchange in the face of a negative CT and PET suggests a primary autoimmune process rather than a paraneoplastic etiology, though we admit that it is premature to rule out remission and we will continue to follow herDisclosure: Dr. Alwaki has nothing to disclose.

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...

Paroxysmal Dysarthria and Ataxia after Treatment of Brainstem Encephalitis (P6.053)
CONCLUSIONS: Paroxysmal dysarthria and ataxia is most often recognized as a complication of multiple sclerosis, but it can occur in other neurologic diseases with midbrain lesions near or involving the red nucleus. Effective treatments include carbamazepine, acetazolamide, lamotrigine, and phenytoin.Study Supported by: N/A.Disclosure: Dr. Klaas has nothing to disclose. Dr. Boes has nothing to disclose.
