Hyperdopaminergism in Lenticulostriate Stroke-Induced Restless Legs Syndrome: A Neuro Imaging Study (P7.303)
CONCLUSIONS: A systematic study of small lesions associated with RLS may contribute to understanding the pathophysiological mechanisms underlying this condition. In this regard, the body of the caudate nucleus might be an important structure. The isotopic results reinforce the hypothesis of an increased dopaminergic tone in the striatum as part of RLS pathophysiology. Thus, the efficacy with low doses of dopaminergic agonists in RLS could be explained by stimulation of inhibitory D2-like autoreceptors.Disclosure: Dr. Ruppert has nothing to disclose.

Correlation of Transcranial Doppler Breath Holding Test and Acetazolamide SPECT Scan for Anterior Circulation Steno-Occlusive Disease (P6.019)
Conclusions: There was a modest correlation between TCD-R and acetazolamide SPECT scan for anterior circulation steno-occlusive disease in our patient cohort. TCD-R demonstrated higher sensitivity for the detection of poor cerebrovascular reserve than acetazolamide SPECT. Further studies are needed to determine which study is more useful in the management of this high-risk population. Disclosure: Dr. Parikh has nothing to disclose. Dr. Cerejo has nothing to disclose.

Susceptibility Weighted MRI and Regional Cerebrovascular Reservoir Capacity in Angiography Proven Large Artery Disease in Acute Ischemic Stroke and Transient Ischemic Attack (P6.247)
CONCLUSIONS:Cortical vessel signs on susceptibility-weighted image have an association with regional cerebrovascular reservoir capacity. And this snapshout image would be a useful tool in the real world of clinical practice in evaluating cerebrovascular perfusion status. But longer follow up in much larger populations are needed.Disclosure: Dr. Lee has nothing to disclose. Dr. Won has nothing to disclose. Dr. Yoo has nothing to disclose.
