Association of parathyroid hormone with 20-year cognitive decline: The ARIC study
Conclusions: Our work does not support an independent influence of PTH on cognitive decline in this population-based cohort study.

Success of Intravenous Infusion of Verapamil for Refractory Vasospasm in aneurysmal Subarachnoid Hemorrhage (P2.291)
Conclusions:This report indicates that intravenous continuous infusion of verapamil may be used for rescue therapy in transiently responsive cerebral vasospasm to IA verapamil. This therapy did not seem to compromise hemodynamic stability or increase ICP.Disclosure: Dr. Mehta has nothing to disclose. Dr. Kulhari has nothing to disclose. Dr. Z Arango has nothing to disclose.

Reversible Cerebral Vasoconstriction Syndrome Presenting as Coma (P4.354)
Conclusions: RCVS rarely can present with coma and multifocal infarctions. Exact pathophysiology remains unknown but disruption of sympathetic tone and endothelial dysfunction have been implicated. A high index of suspicion is required to minimize disease complications and prevent improper withdrawal of care.Disclosure: Dr. Khan has nothing to disclose. Dr. Adcock has nothing to disclose.

Collateral Blood Flow Availability in Acute Ischemic Stroke: A Case Report (P4.360)
Conclusion: This case supports earlier autopsy specimen dissections indicating most borderzone collaterals linking to adjacent vascular territories are too small to generate the immediate flow needed to spare tissue proximal to a middle cerebral stem occlusion. Assuming acute vasodilation is possible for these vessels, the acute use of vasodilators such as nitroglycerin or hydralazine and calcium-channel blockers like Nimodipine could provide an area for future study.Disclosure: Dr. Rostanski has nothing to disclose.

CT Angiogram Helps to Predict Ischemic Stroke in Dizzy Patients, but NOT Better than the Clinical Examination (P3.084)
Conclusions: In patients with subjective dizziness, stroke risk factors and focal exam findings predict acute ischemic stroke. Calcification on CTA is also predictive, but does not significantly improve sensitivity.Disclosure: Dr. Chen has nothing to disclose. Dr. Schneider has nothing to disclose.

Metabolomic analysis reveals novel small molecule plasma markers of hyperacute ischemic stroke (S30.001)
Conclusions: Utilizing targeted metabolomics, we found increased Glu and PLA and decreased citrate level in AIS patients within 6 hours of stroke onset. Glu, an excitatory neurotransmitter, and PLA, a known apoptotic marker, are both found in CSF and peri-infarct zone of ischemic stroke. Citrate is not only important in energy metabolism (anaerobic glycolysis), but also binds blood calcium to prevent clot formation. Building on previous studies, this study is a first step to help understand early metabolic landscape of AIS and highlights the role of potential CSF contribution to peripheral metabolic contents. However, furt...

Amyotrophic Lateral Sclerosis (ALS) with Laboratory Abnormalities of Unknown Significance (LAUS) --Where Does It Begin and Where Does It End? (P4.144)
CONCLUSIONS: Further detailed analysis of progression rate by site of onset, sex, age, treatment will require assimilation of clinic-based datasets of properly analyzed ALS-LAUS patients from multiple clinic sites. The appropriate role of IVIg in ALS-LAUS patients requires further study following explication of the natural history of these patients compared with non-ALS-LAUS patients. The determination as to whether auto-antibodies to additional antigens may play a role in the progression rate of ALS-LAUS compared with sporadic ALS needs to be systematically studied.

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.
