Stroke Volume Predicts Nocturnal Hypoxemia in the Acute Ischemic Stroke after Intravenous Thrombolysis
The Goal: The aim of the study was to investigate whether stroke volume or the presence of ischemic stroke lesion on follow-up computed tomography 1 day after admission had association with sleep apnea among ischemic stroke patients undergoing thrombolysis. Materials and Methods: We prospectively recruited 110 consecutive ischemic stroke patients and performed computed tomography on admission and after 24 hours after intravenous thrombolysis. Stroke volume was measured from post-thrombolysis computed tomography scans.

Recanalisation therapies for wake-up stroke.
CONCLUSIONS: There is insufficient evidence from randomised controlled trials for recommendations concerning recanalisation therapies for wake-up stroke. Results from ongoing trials will hopefully establish the efficacy and safety of such therapies. PMID: 30129656 [PubMed - as supplied by publisher]

Relationship Between Sleep Apnea and Coronary Artery Calcium in Patients With Ischemic Stroke
Conclusion: Our findings indicate a relationship between coronary atherosclerotic burden measured by the CAC score and the severity of sleep apnea. Performing polysomnography could be useful for investigating the severity of hidden coronary artery disease among these patients.

Visual hallucinations in patients with acute stroke: a prospective exploratory study
ConclusionsVisual hallucinations are relatively frequent in patients with acute stroke and they are self‐limited. Patients with occipital lesions and sleep disturbances are more likely to suffer them.

Relationship between sleep disordered breathing and coronary artery calcium in ischemic stroke patients
Introduction: Obstructive Sleep Apnea (OSA) is associated with increased risk of stroke and cardiovascular mortality. In ischemic patients, the major cause of death during follow-up is coronary artery disease. Coronary calcium score (CAC) is a score measured from quantification of calcified plaques with chest computed tomography. CAC has been shown to be associated with future risk of myocardial infarction and cardiovascular mortality. Several studies showed the positive correlation between sleep apnea and CAC in normal population, which may be contributed by progressive worsening of atherosclerosis.

A Case of Transient Global Amnesia: A Review and How It May Shed Further Insight into the Neurobiology of Delusions
Conclusion In closing, our patient’s episode of TGA combined with her emotional and perceptual response lends credence to the proposal of a “fear/paranoia” circuit in the genesis of paranoid delusions—a circuit incorporating amygdala, frontal, and parietal cortices. Here, neutral or irrelevant stimuli, thoughts, and percepts come to engender fear and anxiety, while dysfunction in frontoparietal circuitry engenders inappropriate social predictions and maladaptive inferences about the intentions of others.[54] Hippocampus relays information about contextual information based on past experiences and the current situat...

RLS and PLMS, an avenue toward better understanding the natural history and spectrum of cerebrovascular disease?
In an article in this issue of Sleep Medicine, Gupta et al report prevalence of Restless Legs Syndrome (RLS) prior to stroke onset in 346 first-ever stroke survivors, both hemorrhagic and ischemic, in an observational cohort in New Delhi, India. RLS was diagnosed retrospectively based on International Restless Legs Syndrome Study Group (IRLSSG) criteria and correlated with stroke characteristics such as location–subcortex versus cortex and arterial territory based on Computed Tomography or Magnetic Resonance Imaging).

Sex Differences in Sex Hormone Profiles and Prediction of Consciousness Recovery After Severe Traumatic Brain Injury
Conclusion: These findings indicate that TBI differentially affects the levels of sex-steroid hormones in men and women patients. Plasma levels of testosterone could be a good candidate blood marker to predict recovery from unconsciousness after sTBI for male patients. Introduction Traumatic brain injury (TBI) is a major cause of death and disability worldwide and is increasing in incidence (1). Patients with acute severe TBI (sTBI) often develop severe disorders of consciousness, i.e., coma, minimally conscious state or vegetative state. Although many patients may regain consciousness during the 1-month post-TBI p...

How AI Is Changing Medical Imaging to Improve Patient Care
That doctors can peer into the human body without making a single incision once seemed like a miraculous concept. But medical imaging in radiology has come a long way, and the latest artificial intelligence (AI)-driven techniques are going much further: exploiting the massive computing abilities of AI and machine learning to mine body scans for differences that even the human eye can miss. Imaging in medicine now involves sophisticated ways of analyzing every data point to distinguish disease from health and signal from noise. If the first few decades of radiology were about refining the resolution of the pictures taken of...

Comparisons of clinical symptoms in biomarker‐confirmed Alzheimer's disease, dementia with Lewy bodies, and frontotemporal dementia patients in a local memory clinic
ConclusionMemory impairment and apathy are not useful discriminative symptoms in diagnosing AD, DLB, and FTD. Apraxia favours AD. Hallucinations, particularly well‐formed visual hallucinations, favour DLB. Overall, behavioural and neuropsychiatric symptoms of dementia symptoms are common among the three groups of dementia patients.

Computational tools could change the way sleep apnea is treated
Imagine that before performing surgery, doctors could consult software that would determine the actual effectiveness of the procedure before even lifting a scalpel. With the use of a computational model of the human airway being developed by Jeff Eldredge, a professor at the Henry Samueli School of Engineering and Applied Sciences at UCLA, people who suffer from sleep apnea may one day benefit from such a scenario. Previously, Eldredge, a professor of mechanical and aerospace engineering, had been working on creating models that simulated the interactions between blood and vessel walls with Shao-Ching Huang, an expert in h...

Acute bithalamic infarct manifesting as sleep-like coma: A diagnostic challenge
Publication date: December 2016 Source:Journal of Clinical Neuroscience, Volume 34 Author(s): Asaf Honig, Ruth Eliahou, Roni Eichel, Ari Aharon Shemesh, Tamir Ben-Hur, Eitan Auriel Bilateral thalamic infarction (BTI) typically presents as a sleep-like coma (SLC) without localizing signs, posing a diagnostic challenge that may lead the treating physician to search for toxic or metabolic causes and delay treatment. We review our experience with BTI of different etiologies, and emphasize the critical role of timely imaging, diagnosis, and management in a series of 12 patients with a presentation of SLC and acute BTI who were...

Association of Subjective and Objective Sleep Duration as well as Sleep Quality with Non-Invasive Markers of Sub-Clinical Cardiovascular Disease (CVD): A Systematic Review.
CONCLUSIONS: Overall, our review provided mixed results, which is generally in line with published literature, with most of the studies showing a significant relationship with subclinical CVD, but only some studies failed to demonstrate such an association. Although such mechanistic relationship needs further evaluation in order to determine appropriate screening strategies in vulnerable populations, this review strongly suggested the existence of a relationship between abnormal sleep duration and quality with increased subclinical CVD burden.
