Various movement disorders associated with cerebral infarction have been introduced. However patients with anterior cerebral artery territory infarction presenting with hemichoreoballism have never been reported. We present a 64-year-old man with hemichoreoballism and frontal alien hand syndrome on his right hand. Diffusion weighted brain MRI revealed hyperintensities in anterior two third of corpus callosum and superior frontal gyrus. Hemichoreoballism was improved after one day treated by clonazepam. We report the case with hemichoreoballism after anterior cerebral artery territory infarction. ...
Objectives Infections in patients with stroke are common and significantly affect outcome. Various predictors of poststroke infections were determined, such as degree of neurological impairment and implementation of therapeutic interventions. The authors investigated whether stroke location and stroke size are independent risk factors for poststroke infections.. Methods 591 patients with acute stroke who were treated on our stroke unit were included in a prospective observational study. Predefined endpoints were pneumonia, urinary-tract infection (UTI) and other infections. The OR of infections was calculated for various stroke locations, stroke lateralisation and three categories of stroke size. Logistic regression models were used to adjust for factors significantly associated with poststroke infections in a single-factor analysis.. Results In the single-factor analysis, the left anterior cerebral artery territory was associated with pneumonia. After adjustment for relevant covariates, this ...
Background: Combined IV TPA and catheter-based reperfusion is an emerging treatment strategy for acute ischemic stroke. Both patient care and clinical trial design would be enhanced by delineation of which patients rapidly respond to IV TPA alone, before endovascular therapy can be initiated.. Methods: In a prospectively maintained registry of patients treated under a general policy of combined IV TPA and endovascular therapy, we analyzed subjects with MRA/CTA-confirmed anterior circulation occlusions prior to IV TPA start.. Results: Among 118 patients meeting study entry criteria, age was mean 71.5 (SD 14.5), 53.0% were female, and baseline NIHSS was 14.4 (SD 7.1). Confirmed sites of occlusion prior to IV TPA were internal cerebral artery (ICA) in 22.9%, M1 segment of middle cerebral artery (MCA) in 50.0%, and M2-3 in 27.1%. Among patients undergoing catheter cerebral angiography, median time from start of IV TPA to diagnostic catheter angiogram was 75 mins (IQR 50-113). A total of 48 (40.7%) ...
Background: Serial ASPECTS of ischemic stroke lesion evolution from baseline to 24-hours has been established as an effective surrogate endpoint in endovascular therapy. The use of this imaging shift has not been implemented beyond thrombectomy trials to estimate impact of endovascular therapy in large-scale registry data.. Methods: The STRATIS Imaging Core Lab, blind to all clinical data, independently determined ASPECTS scores on baseline and 24-hour studies. ASPECTS regional involvement and resulting total scores were analyzed in anterior circulation occlusions in STRATIS. Statistical analyses calculated the proportion of subjects with 0 ASPECTS score shift and separately, those with shifts ,4, 5, 6 points. Clinical predictors of ASPECTS shift and regional involvement were determined.. Results: Baseline ASPECTS (n=517) was 8.2 ± 1.59 (median 8.0 (2, 10)) and 24-hour ASPECTS (n=547) was 6.0 ± 2.92 (median 7.0 (0, 10)). Serial ASPECTS (n=487) revealed change of -2.1 ± 2.41 (median-1.0 (-10, ...

Having spent much of last year releasing one-off singles, Skott has begun her 2018 with the surprise release of a brand new EP.. The new four-track release Stay Off My Mind is being led by the title-track, which sees her sample the anthemic Peter, Bjorn and John single Young Folks.. Speaking on the track, Skott said, "Ive been working a bit with Bjorn from Peter Bjorn & John, and we meant to replace the sample, but it just worked so perfectly so its ended up in the song. The producers and I couldnt decide on a bpm for the song - when the verse felt fast, the chorus felt slow, and vice versa, so the song actually switches tempo four times".. But despite its upbeat sound, the track was written in memory of a close friend of hers who passed away recently, with her adding, "Ultimately its a song about missing someone so much that youre almost living more in the past than in the present. Its bittersweet because we can have such fond memories, but life goes on and sometimes having flashbacks ...
Tom Matthews wrote: , we can (and , should) divide all of the various theories of aging into those which are , secondary or derivative and those which are primary or ultimate. Absolutely. Thats the only way to develop a proper theory of theories of aging, in my view. I think its cleaner to classify the changes than the theories, though. A theory of aging, in the sense youre using the term, is basically a statement that a particular age-related change is a dominant determinant of the rate of most (or all) other changes (and of itself), so its equivalent to classify changes rather than theories, but less open to misinterpretation. , Furthermore, it appears , that research is at the stage where there is good evidence that certain , derivative aging changes are implicated in specific aging pathologies, , but the evidence for implication of any ulimate aging changes is weaker , (although there clearly *must* be ultimate causes).

In 94% brain specimens had a recurrent artery of Heubner while in 6% of the brains we could not identify the artery. The artery was present as a single vessel in 76% of cases, and as a double vessel in 24% of cases. It originated from the junction of the anterior cerebral artery and the anterior communicating artery in 60% of the specimens, from the A2 segment of the anterior cerebral artery in 21% of the specimens, and from the A1 segment of the anterior cerebral artery in 19%. The length of the recurrent artery of Heubner ranged from 14 to 46 mm, with a mean value of 24 mm. The diameter of the artery ranged from 0.9 to 2.8 mm, with a mean value of 1.3 mm. ...
Hi, One week ago, after an MRI and then an MRA, two small aneurysms were discovered on my Anterior Communicating Artery, one leaning anteriorly and the other posteriorly. The MRA states that all of the blood flow is running through the A2 segment of the Anterior Cerebral Artery, since I am missing the A1 segment of the Anterior Cerebral Artery and the A2 segment looks fenestrated as well. In addition, the MRA could not rule out MS or other demylinating diseases, which was the initial

Ischemic lesions within the territory of the anterior cerebral artery present with a variety of clinical signs and symptoms. Among these, frontal alien hand syndrome is rare and easily overlooked in the acute clinical setting, but significantly impacts on functional activities of daily life. Given its rareness, very little is known about its long-term outcome. To shade some more light onto this issue, clinical presentation, course of rehabilitation and outcome of two illustrative cases of frontal alien hand syndrome following anterior cerebral artery stroke are presented. Within seven and nine months from symptom onset, respectively, the clinical symptoms of frontal alien hand had resolved completely in both cases. We conclude that frontal alien hand syndrome has a favourable long-term outcome.
Dissociated horizontal deviation after traumatic brain injury.. Korean J Ophthalmol. 2010 Dec;24(6):377-9. Authors: Lee TE, Cha DS, Koh SB, Kim SH. A 4-year-old boy visited the hospital with exotropia after brain hemorrhage caused by trauma. He had undergone decompressive craniectomy and cranioplasty 18 months prior to presentation at our hospital. An alternate prism cover test showed more than 50 prism diopters (PD) of left exotropia when he was fixing with the right eye and 30 PD of right exotropia when he was fixing with the left eye at near and far distance. On the Hirschberg test, 60 PD of left exotropia was noted in the primary position. Brain computerized tomography imaging performed 18 months prior showed hypodense changes in the right middle cerebral artery and anterior cerebral artery territories. Subfalcian herniation was also noted secondary to swelling of the right hemisphere. The patient underwent a left lateral rectus muscle recession of 7.0 mm and a left medial rectus muscle ...

During conventional cardiopulmonary bypass (CPB) there is no active perfusion of the pulmonary circulation and the mechanical ventilation is ceased leaving the lungs exposed to warm ischemia. Pulmonary dysfunction is seen in varying degrees after major surgery, but more severe in cardiac surgery patients probably due to the effects of CPB. The evidence for effect and safety are limited, but active pulmonary artery perfusion during CPB could be beneficial for the patients postoperative oxygenation. Our aim was in a randomised clinical trial to assess primarily the effect of pulmonary artery perfusion during CPB on postoperative oxygenation in patients diagnosed with chronic obstructive pulmonary disease (COPD), secondarily to assess other possible benefits and harms. Furthermore, we wanted in a systematic review with meta-analyses of all randomised clinical trials to investigate the pooled effects of pulmonary artery perfusion during CPB. We planned and conducted a randomised, partly blinded, ...
Over its previous two editions, Understanding Other Minds has established itself as a classic text on autism and theory of mind. In the 15 years since the last edition was prepared, the neuroimaging literature on theory of mind has expanded significantly, revealing new brain regions and their role in regard to theory of mind. Other major changes include developments in the study of infants and in the fields of hormones and genetics.
The formation of an area of NECROSIS in the CEREBRUM caused by an insufficiency of arterial or venous blood flow. Infarcts of the cerebrum are generally classified by hemisphere (i.e., left vs. right), lobe (e.g., frontal lobe infarction), arterial distribution (e.g., INFARCTION, ANTERIOR CEREBRAL ARTERY), and etiology (e.g., embolic infarction ...
Researchers monitored the volunteers blood flow through their brains with an ultrasound. They found that increased blood flow through the anterior cerebral artery, located in the middle of the brain behind the eyes, caused it to swell up suddenly as the temperature dropped. This causes the pain we know as brain freeze.. The scientists described this act as a defensive mechanism for the brain. Since the temperature drops and the brain requires warmth to work, this widening of the artery provides a way to move the coldness along quicker and return the artery to its normal temperature. So the next time you get a blindly headache after downing a milkshake, know thats just your brains way of protecting itself. ...

After all were animals, biological things, and effects of some molecules and physical forces leading to some chains of chemical reactions or electrical or physical activations; why shall we bother to behave as selfishly as some unicellular organism swimming with its flagella or something in search of a better place of survival even without understanding the meaning of it? But we do bother, all of us, as per the capacity of structures called as brains or more broadly as per the complexity of the bodies of the organisms. Responses of a more evolved multicellular organism to a stimulus are different than those of a unicellular, biologically backward animal. Im not sure about the plants, fungi or animals with extremely primitive nervous tissue development; but in humans and animals with developed brain there is something called as cognition… we have a picture of the outer world in what is called as our mind and we all live in our own private worlds formed in our minds due to the trillions of ...

Both the immobilization of the unaffected arm combined with physical therapy (forced arm use, FAU) and voluntary exercise (VE) as model for enriched environment are promising approaches to enhance recovery after stroke. The genomic mechanisms involved in long-term plasticity changes after different means of rehabilitative training post-stroke are largely unexplored. The present investigation explored the effects of these physical therapies on behavioral recovery and molecular markers of regeneration after experimental ischemia. 42 Wistar rats were randomly treated with either forced arm use (FAU, 1-sleeve plaster cast onto unaffected limb at 8/10 days), voluntary exercise (VE, connection of a freely accessible running wheel to cage), or controls with no access to a running wheel for 10 days starting at 48 hours after photothrombotic stroke of the sensorimotor cortex. Functional outcome was measured using sensorimotor test before ischemia, after ischemia, after the training period of 10 days, at 3 and 4

Background: A cardiac origin in ischemic stroke is more frequent than previously assumed, but it is not clear which patients benefit from cardiac work-up if obvious cardiac pathology is absent. We hypothesized that thromboembolic stroke with a cardiac source occurs more frequently in the posterior circulation compared with thromboembolic stroke of another etiology. Methods: We performed a multicenter observational study in 3,311 consecutive patients with ischemic stroke who were enrolled in an ongoing prospective stroke registry of 8 University hospitals between September 2009 and November 2014 in The Netherlands. In this initiative, the so-called Parelsnoer Institute-Cerebrovascular Accident Study Group, clinical data, imaging, and biomaterials of patients with stroke are prospectively and uniformly collected. We compared the proportions of posterior stroke location in patients with a cardiac stroke source with those with another stroke etiology and calculated risk ratios (RR) with ...
We present a new approach to create painterly renderings of an animated 3D scene, allowing a controllable trade-off between scene fidelity and stylistic design. Our approach extends and complements existing systems in order to ensure temporal coherence while maintaining consistent stroke density, and allowing a wide variety of stroke styles. It is based on a new dynamic painting algorithm which selects a suitable set of sample stroke locations based on an object-space hierarchy. Strokes are created at these locations, with attributes assigned using arbitrary stylistic choices: examples include scene-derived decisions such as having stroke orientation follow curvature or silhouette directions, or user-supplied constraints such as global orientation or thickness. Stroke rendering is then performed using appropriately filtered information from a set of G-buffers. We describe an improved stroke rendering technique which allows a faithful depiction of the scene while letting the user specify his prefered

Based on previous clinical studies, we have found that patients with diabetes mellitus (DM) who are having carotid endarterectomy (CEA) have a four-fold higher incidence of cognitive dysfunction, 1 day and 1 month after surgery, than a control group of elderly diabetic patients having spine surgery.. We hypothesize that this increased incidence is due to sub-cortical ischemia associated with the clamping of the ipsilateral carotid artery, because intra-operatively we rarely see EEG changes, or a significant number of emboli upon clamping or unclamping the carotid artery, or new cortical lesions of ischemia by MRI after surgery. In order to decrease cognitive dysfunction in patients with DM, we propose to randomize them to either i) have a shunt placed across the surgical site assuming it is surgically feasible or ii) be treated by conventional management during which time a shunt is placed only in the unlikely event of significant cortical ischemia determined by EEG, which occurs in about 5% ...

Transcallosal inhibition (TCI), assessed using transcranial magnetic stimulation (TMS), can provide insight into the neurophysiology of aging and of neurological disorders such as stroke. However, the reliability of TCI using the ipsilateral silent period (iSP) has not been formally assessed, despite its use in longitudinal studies. This study aimed to determine the reliability of iSP onset latency, duration and depth in healthy young and older adults. A sample of 18 younger (mean age 27.7 years, range 1 9 - 42) and 13 older healthy adults (mean age 68.1 years, range 58 - 79) attended four sessions whereby the iSP was measured from the first dorsal interosseous (FDI) muscle of each hand. 20 single pulse stimuli were delivered to each primary motor cortex at 80 % maximum stimulator output while the participant maintained an isometric contraction of the ipsilateral FDI. The average onset latency, duration of the iSP, and depth of inhibition relative to baseline electromyography (EMG) activity was

These kinds of aggressive behaviours need to be addressed when children are small. I appreciate that many refuse to use drugs. Drugs are a very personal choice and I respect that.
