Unusual case of recurrent SMART (stroke-like migraine attacks after radiation therapy) syndrome
Ramnath Santosh Ramanathan, Gayathri Sreedher, Konark Malhotra, Zain Guduru, Deeksha Agarwal, Mary Flaherty, Timothy Leichliter, Sandeep RanaAnnals of Indian Academy of Neurology 2016 19(3):399-401Stroke-like migraine attacks after radiation therapy (SMART) syndrome is a rare delayed complication of cerebral radiation therapy. A 53-year-old female initially presented with headache, confusion and left homonymous hemianopia. Her medical history was notable for cerebellar hemangioblastoma, which was treated with radiation in 1987. Her initial brain MRI (magnetic resonance imaging) revealed cortical enhancement in the right te...

Beyond the Arcuate Fasciculus: Damage to Ventral and Dorsal Language Pathways in Aphasia.
Abstract Previous regional-based diffusion tensor imaging (DTI) studies focused on impairment of the arcuate fasciculus in aphasia; little is known about the extent to which aphasia severity is affected by damage to both ventral and dorsal language white matter (WM) pathways. To understand whether disconnection of these pathways contributes to clinical symptoms, we assessed the relationship between the alterations of WM integrity and clinical characteristics in acute aphasia after stroke. Eighteen patients with acute aphasia and age-, gender-, and education-matched healthy controls underwent language assessment an...

Screening tests for aphasia in patients with stroke: a systematic review
Abstract Aphasia has a large impact on the quality of life and adds significantly to the costs of stroke care. Early recognition of aphasia in stroke patients is important for prognostication and well-timed treatment planning. We aimed to identify available screening tests for differentiating between aphasic and non-aphasic stroke patients, and to evaluate test accuracy, reliability, and feasibility. We searched PubMed, EMbase, Web of Science, and PsycINFO for published studies on screening tests aimed at assessing aphasia in stroke patients. The reference lists of the selected articles were scanned, and several e...

Internal maxillary artery to intracranial artery bypass: a case series of 31 patients with chronic internal carotid/middle cerebral arterial-sclerotic steno-occlusive disease.
CONCLUSIONS: By supplying an adequate flow to a larger flow territory of chronically stenotic/occlusive major cerebral arteries, IMA bypass surgery is efficient for restoring hemodynamics in selected patients and improving their neurological deficits.

Language improvement one week after thrombolysis in acute stroke
ConclusionsLesion size and initial aphasia severity are the main predictors of aphasia recovery one week after thrombolysis. A NIHSS composite verbal score seems to capture the global linguistic performance better than the language item alone.

Imaging effects related to language improvements by rTMS.
Authors: Heiss WD Abstract The functional deficit after a focal brain lesion is determined by the localization and the extent of the tissue damage. Since destroyed tissue usually cannot be replaced in the adult human brain, improvement or recovery of neurological deficits can be achieved only by reactivation of functionally disturbed but morphologically preserved areas or by recruitment of alternative pathways within the functional network. The visualization of disturbed interaction in functional networks and of their reorganization in the recovery after focal brain damage is the domain of functional imaging modali...

Network dysfunction predicts speech production after left hemisphere stroke
Conclusions: Speech production is dependent on complex interactions among widely distributed brain networks, indicating that residual speech production after stroke depends on more than the restoration of local domain-specific functions. Our understanding of the recovery of function following focal lesions is not adequately captured by consideration of ipsilesional or contralesional brain regions taking over lost domain-specific functions, but is perhaps best considered as the interaction between what remains of domain-specific networks and domain-general systems that regulate behavior.

Case Report - IV Thrombolysis with Subsequent SAH in Setting of Occult Spontaneous MCA Dissection (P4.346)
Conclusions: Spontaneous isolated middle cerebral artery dissection is a rare entity which most commonly presents as ischemic stroke and may complicate the administration of IV-rtPA. It should be considered in cases of thrombolysis and development of subsequent SAH.Disclosure: Dr. Saeed has nothing to disclose. Dr. Chaudhry has nothing to disclose.

Acute Stroke Due to High Voltage Electrocution (P4.347)
We present a case of acute stroke due to high voltage electrocution. Case presentation 38 year old white male accidently grabbed a live wire in the field and got electrocuted. He sustained 2nd degree electric burns at the entry wound in his right palm with a small exist wound in the right foot. On admission, he was stable with total amnesia of the incident event. He had no major medical, psychiatric or substance abuse problems. He remained confused in the hospital with expressive aphasia. Repeat CT scan of the head showed multiple hypo density in both frontal and left partial region. MRI confirmed the presence of acute isc...

Unusual Intersection: Elucidating the Role of Erdheim Chester Disease in Stroke (P4.366)
Conclusion:A unifying diagnosis of ECD was identified for this gentleman presenting with a stroke in the setting of critical ICA stenosis. Pathology from his CEA suggests that while ECD involves multisystem inflammation, it did not appear to play a direct role in his stroke.Disclosure: Dr. Sheikhi has nothing to disclose.

Strokes Occurring in the Hospital; Quality of Care and Outcome in a Tertiary Academic Medical Center (P6.045)
Conclusions: Increased symptom recognition was found within the ICU/ER cohorts staffed by specialized nurses. Only small number of patients with in-hospital strokes received brain imaging according to ASA/AHA guidelines which is an important opportunity for QI efforts for this group of patients.Disclosure: Dr. Kamal has nothing to disclose.

Separate neural systems support representations for actions and objects during narrative speech in post-stroke aphasia
Conclusions The finding that the two major grammatical classes in human speech rely on two dissociable networks has both important theoretical implications for the neurobiology of language and clinical implications for the assessment and potential rehabilitation and treatment of patients with chronic aphasia due to stroke.

Non-invasive brain stimulation in early rehabilitation after stroke.
Authors: Blesneag AV, Popa L, Stan AD Abstract UNLABELLED: The new tendency in rehabilitation involves non-invasive tools that, if applied early after stroke, promote neurorecovery. Repetitive transcranial magnetic stimulation and transcranial direct current stimulation may correct the disruption of cortical excitability and effectively contribute to the restoration of movement and speech. The present paper analyses the results of non-invasive brain stimulation (NIBS) trials, highlighting different aspects related to the repetitive transcranial magnetic stimulation frequency, transcranial direct current stimulation...
