Stroke risk after a first late-onset migraine-like transient neurological attack (tna): oxford vascular study tna cohort
Conclusions The short and long–term risks of stroke in patients with a first migraine–like TNA are significantly lower than after a definite TIA. The trend towards a higher stroke risk than the underlying population rate is similar to that seen in studies of individuals with clinically–definite migraine with aura.

The beneficial effect of combining neurology and stroke services
Conclusion We demonstrated that patients presenting with acute neurological symptoms may benefit from early review by a neurology specialist doctor. Rapid and accurate identification and treatment of patients with stroke and non-stroke diagnoses, which are often eminently treatable, ensures that both groups receive the correct treatment and that unnecessary medication and admission is avoided.

Sensitivity of transcranial doppler and transoesophageal echocardiography for the detection of patent foramen ovale in cryptogenic stroke
Conclusions TCD with bubble test is sensitive and specific for the detection of right–to–left shunts due to PFO confirmed at right heart catheterisation. In this population, TOE had low sensitivity for RLS. There was no difference in physical PFO size between TOE positive and negative patients.

A stroke mimic; focal neurological deficits in benign hereditary chorea?
Conclusion This case highlights the difficulties in assessing patients with new focal neurological symptoms in the presence of known, pre existing, neurological disease. It also serves to highlight how often erroneously progressive weakness is mislabelled as a ‘stroke’. Neurologists working together with acute physicians in liaison posts in MAU, provides a unique opportunity to improve overall recognition of neurological disease, and for patients potentially provides a more timely diagnostic work–up and the opportunity for early treatment.

E-021 Pathophysiology, stroke types, collateral formation and aneurysms in moyamoya disease/moya moya syndrome
ConclusionsMMD is presented most commonly with ischemic stroke in the pediatric age group and with hemorrhagic stroke in the adult age group. MMD-associated intracranial aneurysms frequently occur in patients presenting with hemorrhagic unilateral MMD and are associated with an extremely high rate of rupture. Long-standing hemodynamic stress might contribute to the formation of an aneurysm.Disclosures S. Ahmad: None.

E-132 A retrospective analysis of stroke code specificity in predicting acute ischemic events
ConclusionsThis retrospective analysis of stroke codes at MGUH during a 6-month period was 29% specific in predicting AIS. This is significantly lower than what was found in previous studies. Of stroke mimics, TME was the major etiology encompassing 43.6% of cases. The results of our study suggest additional stroke education may be needed for non-neurologists and ancillary staff to appropriately recognize stroke symptoms to better improve the utilization of hospital resources and provide appropriate and efficient care.Disclosures A.

Two-year safety and clinical outcomes in chronic ischemic stroke patients after implantation of modified bone marrow-derived mesenchymal stem cells (SB623): a phase 1/2a study.
CONCLUSIONSIn this completed 2-year phase 1/2a study, implantation of SB623 cells in patients with stable chronic stroke was safe and was accompanied by improvements in clinical outcomes.Clinical trial registration no.: NCT01287936 (clinicaltrials.gov).

Clinical and neuroradiological characteristics of ischemic stroke and subarachnoid hemorrhage in isolated posterior inferior cerebellar artery dissection: Literature review and report of 2 cases
ConclusionPICAD with ischemic stroke is likely under-diagnosed due to the following reasons; 1) patients present with neurological deficits that are non-specific and mild, 2) DSA, which is a gold standard of diagnosing PICAD is not regularly performed in these patients, 3) lack of predisposing factors associated with PICAD in some patients. The mild and non-specific clinical presentation in young adults with PICAD with ischemia probably due to their ability to compensate better given low incidences of other comorbidities. Further investigation regarding the underlying etiology of isolated PICAD, association of proximal PIC...

Long-term follow-up of acute functional stroke mimic in comparison to mild acute ischaemic stroke
Introduction Each year many patients are admitted to the emergency department with a suspicion of acute ischaemic stroke (AIS). There are several conditions that can present with acute stroke-like symptoms, of which the most common are seizures, migraine and functional disorder. The latter are called functional stroke mimics (FSM). While the outcome of patients with AIS has extensively been studied, little is known about the outcome of FSM. Short-term follow-up studies in acute FSM have shown that about 80% of patients with FSM still reported symptoms after 2 months,1 but long-term follow-up studies are lacking. We therefo...

Atypical clinical presentations are common in TIA and minor stroke patients with DWI-MRI confirmed ischaemia
Conclusions Over one-third with DWI-confirmed TIA/minor stroke present atypically. The value of atypical symptoms in excluding ischaemia, particularly in patients with vascular risk factors, appears limited.

The spectrum of migraine in 306 patients with cadasil
In conclusion, the spectrum of migraine in CADASIL differs from that in the general population. Acute encephalopathy is a common feature of CADASIL and usually evolves from a migraine episode. Non-migraneurs have a higher risk of developing stroke, however the reasons for this are not well understood.

Basilar extension and posterior inferior cerebellar artery involvement as risk factors for progression of the unruptured spontaneous intradural vertebral artery dissection
Conclusions Thus, some vertebrobasilar morphologies might be markers of the progression of unruptured siVAD. Although all unruptured siVAD patients should be closely monitored, those with basilar extension and posterior inferior cerebellar artery involvement should perhaps be more carefully followed than those without such morphologies.

Cortical susceptibility-weighted imaging hypointensity after stroke-like episode in MELAS
A 49-year-old woman with a known m.3243A>G tRNALeu(UUR) mutation (ie, the most frequent mutation in mitochondrial encephalopathy, lactic acidosis and stroke-like episodes (MELAS)) diagnosed in the presence of migraine, diabetes mellitus, neurosensory hearing loss, short stature, cognitive deficit, ataxia and elevated lactate levels, presented with subacute aphasia and right hemiplegia. Brain MRI showed a typical stroke-like lesion in the left temporal and parietal lobe and prerolandic cortex. At this time, gradient-echo T2-weighted imaging showed hyperintensities in the involved regions (also visible on T2-weighted and ...

Management and outcome of spontaneous cerebral venous sinus thrombosis in a 5-year consecutive single-institution cohort
Conclusions In our series, the majority (92.9%) of patients with spontaneous dural sinus thrombosis had a favorable clinical outcome as defined by a mRS ≤2. Further prospective studies are needed to study the impact of anticoagulation on the clinical course of the disease.
