Cannabis linked to brain differences in the young
Conclusion This study found differences between young recreational cannabis users and non-users in the volume and structure of the nucleus accumbens and amygdala, which have a role in the brain’s reward system, pleasure response, emotion and decision making. However, as this was only a cross sectional study taking one-off brain scans of cannabis users and non-users, it cannot prove that cannabis use was the cause of any of the differences seen. It is not known whether cannabis use could have caused these changes in regular users.   Or conversely whether the cannabis users in this study had this brain structure to sta...

Stroke mortality increased by drinking alcohol several times a week
Consuming alcohol more frequently than twice a week increases the risk of stroke mortality in men, according to a study carried out at the University of Eastern Finland. The results show that the effects of alcohol are not limited to the amount consumed, but also the frequency of drinking matters. The results were published in Acta Neurologica Scandinavica.Excessive consumption of alcohol is associated with a variety of different diseases.

Computers enable researchers to "see" neurons to better understand brain function
A study conducted by local high school students and faculty from the Department of Computer and Information Science in the School of Science at Indiana University-Purdue University Indianapolis reveals new information about the motor circuits of the brain that may one day help those developing therapies to treat conditions such as stroke, schizophrenia, spinal cord injury or Alzheimer's disease."MRI and CAT scans of the human brain can tell us many things about the structure of this most complicated of organs, formed of trillions of neurons and the synapses via which they communicate.

Parental smoking 'ages' children’s arteries
ConclusionOverall, this secondary analysis study provides preliminary evidence of the effects of parental passive smoking on the artery walls of children and adolescents in adulthood. The researchers attempted to adjust for potential factors that could influence risk (confounders), such as: age sex height weight smoking status physical activity levels alcohol consumption schooling level of the parent(s)In their analysis, they also took into consideration cardiovascular risk factors of the participants in adulthood. There are some limitations to the study, which are worth noting. Parental smoking status was self-re...

Study shows value of calcium scan in predicting heart attack, stroke among those considered at risk
A new study shows that coronary artery calcium (CAC) screening, an assessment tool that is not currently recommended for people considered at low risk, should play a more prominent role in helping determine a person's risk for heart attack and heart disease-related death, as well as the need for angioplasty or bypass surgery. CAC screening provides a direct measure of calcium deposits in heart arteries and is easily obtained on a computed tomography (CT) scan."We showed that by using only the traditional risk factors, we miss a significant percentage of individuals at high risk.

Test could give two-year warning for Alzheimer's
Conclusion The researchers suggest that Alzheimer's disease can be predicted with an accuracy of 87.5% when thinning of the cortex in the right anterior cingulated gyrus is seen on MRI, alongside test results suggesting problems with recall and recognition. This research does not indicate a new "test", as MRI and psychological testing are standard procedures when investigating the signs and symptoms of dementia. What is novel in this approach is looking at a specific combination of results as a potential way of predicting which people with MCI may develop Alzheimer's disease. While this form of testing would be b...

Scan could detect those on brink of heart attack
Conclusion This is a valuable study which shows the promise of using PET-CT with radioactively labelled sodium fluoride (NaF) as a way of identifying fatty deposits in the heart arteries that could be at risk of rupturing and causing a heart attack. The results confirmed that the marker used in this study (NaF) was better than the chemical marker normally used in PET-CT scans (FDG). The technique has the principal value of being a non-invasive technique compared with coronary angiography, which is the standard method used to look at blockages in heart arteries. As it does not involve surgical intervention, this could ha...

Protection against brain abnormalities provided by high serum omega-3 polyunsaturated fatty acid content
According to a new study, high long-chain omega-3 polyunsaturated fatty acid content in blood may lower the risk of small brain infarcts and other brain abnormalities in the elderly. The study was published in Journal of the American Heart Association. In the Cardiovascular Health Study in the USA, 3,660 people aged 65 and older underwent brain scans to detect so called silent brain infarcts, or small lesions in the brain that can cause loss of thinking skills, dementia and stroke. Scans were performed again five years later on 2,313 of the participants...

Having "the talk" when heart disease runs in the family
When heart disease or stroke runs in a family, it's important to talk about it with children and other close family members. The conversation may be hard, but the payoff—better health for all—can be huge, according to the September 2013 Harvard Heart Letter. "Knowing your family history is one of most powerful tools we have to guide how we take care of ourselves from a health perspective," says Dr. Paula A. Johnson, professor of cardiology at Harvard Medical School and chief of the Division of Women's Health at Brigham and Women's Hospital. "This is a chance for your children to make changes that will have both...

The soaring costs of treating dizziness in the emergency room
A new Johns Hopkins research report says emergency room visits for severe dizziness have grown exponentially in recent years, with costs topping $3.9 billion in 2011 and projected to reach $4.4 billion by 2015. The investigators say roughly half a billion a year could be saved immediately if emergency room physicians stopped the routine and excessive use of head CT scans to search for stroke in dizzy patients, and instead used simple bedside physical exams to identify the small group of patients that truly needs imaging...

Keogh review on hospital deaths published
Conclusion In a letter to the secretary of state, Professor Keogh reports that assessments of the 14 hospital trusts have been highly rigorous and uncovered problems in care that had not been exposed before. He warns against hasty reactions and pointing the finger of blame. Any immediate safety issues discovered are said to have been dealt with. Professor Keogh states that considered debate is needed, as well as co-ordinated efforts to improve care with a future focus on accountability.   Analysis by Bazian. Edited by NHS Choices.

'Risky' Stroke Prevention Procedure May Be Safe In Some Patients
A major study published in the Lancet Neurology, funded by the Medical Research Council (MRC) and the Stroke Association, has found that stenting in the carotid artery (in the neck) is as safe as carotid artery surgery at reducing stroke risk in some patients. The research, which was part of the International Carotid Stenting Study (ICSS), reveals that stenting is equally as safe as surgery in patients who show few signs of changes to brain tissue (known as white matter lesions) in a brain scan...

Identification Of Brain Regions Involved In Impersonations And Accents Could Impact Recovery From Brain Injury And Stroke
A study, led by Royal Holloway University researcher Carolyn McGettigan, has identified the brain regions and interactions involved in impersonations and accents. Using an fMRI scanner, the team asked participants, all non-professional impressionists, to repeatedly recite the opening lines of a familiar nursery rhyme either with their normal voice, by impersonating individuals, or by impersonating regional and foreign accents of English. They found that when a voice is deliberately changed, it brings the left anterior insula and inferior frontal gyrus (LIFG) of the brain into play...
