Special MRI scan could identify stroke risk in people with atrial fibrillation
Atrial fibrillation is a heart rhythm disorder that affects millions of people. It can make you feel lousy. Even worse, it can cause potentially disabling or deadly strokes. A special MRI scan may — I stress the “may” — help identify people with atrial fibrillation who are at high risk of having a stroke. This could help many people with this condition to avoid taking warfarin or other clot-preventing medications for life. A normal heartbeat starts in a cluster of cells called the pacemaker. It sits in the heart’s upper right chamber (the right atrium). These cells generate a pulse of electricity that...

Prognostic Importance of Lesion Location on Functional Outcome in Patients with Cerebellar Ischemic Stroke: a Prospective Pilot Study.
We examined 14 patients with first-ever unilateral cerebellar ischemic stroke within 7 days and at 90 days from the onset of stroke by means of the International Cooperative Ataxia Rating Scale. Cerebellar lesions were traced from magnetic resonance imaging performed within 72 h since stroke and region of interest were generated. The association between the International Cooperative Ataxia Rating Scale score and lesion location was determined with the voxel-based lesion-symptom mapping methods implemented in the MRIcro software. Colored lesion-symptom maps representing the z statistics were generated and overlaid onto t...

This Is Where The Brain's Sarcasm Center Is
By: Laura Geggel Published: April 08, 2015 07:23am ET Sarcasm might feel like a natural way to communicate to many people, but it's sometimes lost on stroke survivors. Now, a new study finds that damage to a key structure in the brain may explain why these patients can't perceive sarcasm. Researchers looked at 24 people who had experienced a stroke in the right hemispheres of their brains. Those with damage to the right sagittal stratum tended to have trouble recognizing sarcasm, the researchers found. This bundle of neural fibers connects a number of brain regions, including those that process auditory and visual in...

Statins are 'safe, effective and should be used more widely'
Conclusion This study reviews evidence from randomised controlled trials (RCTs) and observational studies to better evaluate the effects and safety of statin therapy. It provides valuable data on the size of the benefits compared with the risks, informing a topic that has had much media coverage in recent times. The researchers highlight that the benefits of statin therapy for people at risk of cardiovascular disease events far outweigh any possible side effects. But it is still for a doctor and their patient to come to a conclusion about what the best treatment for them may be. If you have been prescribed a statin, it...

Will unpredictable side effects dim the promise of new Alzheimer ’s drugs?
A sea change is underway in the treatment of Alzheimer’s disease, where for the first time a drug that targets the disease’s pathology and clearly slows cognitive decline has hit the U.S. market. A related therapy will likely be approved in the coming months. As many neurologists, patients, and brain scientists celebrate, they’re also nervously eyeing complications from treatment: brain swelling and bleeding, which in clinical trials affected up to about one-third of patients and ranged from asymptomatic to fatal. The side effect—amyloid-related imaging abnormalities, or ARIA—remains mysterious. “We don’...

UCLA study shows promise, offers hope for brain hemorrhage patients
A new endoscopic surgical procedure has been shown to be safer and to result in better outcomes than the current standard medical treatment for patients who suffer strokes as a result of brain hemorrhages, UCLA neurosurgeons have announced.   The findings from their potentially groundbreaking, randomized, controlled phase 2 clinical trial, which was conducted at multiple medical centers, were presented last week at the International Stroke Conference in Honolulu.   "These exciting results offer a glimmer of hope for a condition that most doctors have traditionally considered hopeless," said principal investigator...

Unusual Symptoms of Coronavirus: What We Know So Far
While most people are familiar with the hallmark symptoms of COVID-19 by now—cough, fever, muscle aches, headaches and difficulty breathing—a new crop of medical conditions are emerging from the more than 4 million confirmed cases of the disease around the world. These include skin rashes, diarrhea, kidney abnormalities and potentially life-threatening blood clots. It’s not unusual for viruses to directly infect and affect different tissues and organs in the body, but it is a bit unusual for a primarily respiratory virus like SARS-CoV-2, which is responsible for COVID-19, to have such a wide-ranging reach...

White Matter Microstructural Integrity Is Associated with Executive Function and Processing Speed in Older Adults with Coronary Artery Disease.
CONCLUSION: These results suggest that WM microstructural integrity may be an important neural correlate of executive function even in cognitively intact CAD patients. This study suggests WM damage may be relevant to subtle cognitive decline in a population that may have early neural risk for dementia. PMID: 25499674 [PubMed - as supplied by publisher]

Individual and Joint Effects of Early-Life Ambient PM2.5 Exposure and Maternal Prepregnancy Obesity on Childhood Overweight or Obesity
Conclusions: In the present study, we observed that early life exposure to PM2.5 may play an important role in the early life origins of COWO and may increase the risk of COWO in children of mothers who were overweight or obese before pregnancy beyond the risk that can be attributed to MPBMI alone. Our findings emphasize the clinical and public health policy relevance of early life PM2.5 exposure. https://doi.org/10.1289/EHP261 Received: 29 March 2016 Revised: 08 August 2016 Accepted: 23 August 2016 Published: 14 June 2017 Address correspondence to X.

Why is Clinical fMRI in a Resting State?
Conclusions Despite some perceived impediments to expanding clinical rs-fMRI use, neuroradiologists were generally enthusiastic about rs-fMRI in research and clinical applications, believing that their current workplace MRI systems are suitable for rs-fMRI acquisition. Many of the concerns associated with using rs-fMRI in clinical contexts are related to: (1) developing better methods for minimizing physiological noise effects, (2) improving methods for detecting the spatial characteristics of clinically-relevant brain processing systems in individual patients, and (3) overcoming remaining standardization, training, and r...
