Is bone health linked to brain health?

People who have low bone density may have an increased risk of developing dementia compared to people who have higher bone density, according to a study published in the March 22, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study does not prove that low bone density causes dementia. It only shows an association. “Low […]

Head injury linked to increased risk of death over long-term

Is head injury associated with long-term all-cause mortality risk? Findings from a 30-year follow-up study indicate such an association, researchers reported on Jan 25, 2023 in JAMA Neurology. “Our data reveals that head injury is associated with increased mortality rates even long-term. This is particularly the case for individuals with multiple or severe head injuries,” said lead author, Holly Elser, […]

Why migraine frequently occurs during menstruation

When women suffer migraine attacks, it is often just before or during their monthly period. A team of researchers from Charité – Universitätsmedizin Berlin has now identified a possible explanation. According to their study, published in the journal Neurology,* women who experience migraines have higher levels of CGRP during menstruation. CGRP is a neurotransmitter that is known to play an important […]

Migraine: how to diagnose, manage and prevent

Migraine is a major cause of disability, affecting about 12% of people. A 2-part series published in CMAJ (Canadian Medical Association Journal) on diagnosing and managing the condition with both acute and preventive therapy provides guidance for clinicians “The goal of treatment of migraine attacks is to provide rapid relief from pain and other migraine-related symptoms, to restore patient function and […]

Six minutes of high-intensity exercise could delay the onset of Alzheimer’s disease

Six minutes of high-intensity exercise could extend the lifespan of a healthy brain and delay the onset of neurodegenerative disorders, such as Alzheimer’s disease and Parkinson’s disease. New research published in The Journal of Physiology shows that a short but intense bout of cycling increases the production of a specialised protein that is essential for brain formation, learning and memory, and could […]

Cluster headache may be more severe in women

While cluster headache is more common in men than in women, a new study suggests that the disorder may be more severe for women. The study is published in the December 21, 2022, online issue of Neurology®, the medical journal of the American Academy of Neurology. Cluster headaches are short but extremely painful headaches that can occur many days, or even weeks, […]

Drinking during pregnancy changes baby’s brain structure

A new MRI study reveals that consumption of alcohol, even in low to moderate amounts during pregnancy, can change the baby’s brain structure and delay brain development. Alcohol consumption during pregnancy can expose the foetus to a group of conditions called foetal alcohol spectrum disorders, increasing the risk of learning disabilities, behavioural problems or speech and language delays. ‘Unfortunately, many […]

What happens to our dopamine system when we experience aversive events?

It is well known that the dopamine system plays a crucial role in motivation, learning and movement. One of the main functions of dopamine is to predict the occurrence of rewarding experiences and the availability of rewards in our environment. In this context, the dopamine system informs our brains about so-called ‘reward prediction errors’ – the difference between received and […]

Therapeutic games and brain stimulation mitigates cognitive decline in older adults

Older people may be able to boost their working memory with a new approach that couples online therapeutic games with a non-invasive brain stimulation technique. Working memory is critical for people to function well in everyday life.  This volatile form of memory holds and manipulates a finite amount of information over a short time interval, enabling people to interact with […]

COVID-19 increases risks of neurological problems

Persons infected with the COVID-19 virus are at an increased risk of developing  neurological conditions in the first year after infection, researchers reported on Sept. 22 in Nature Medicine. “Our study provides a comprehensive assessment of the long-term neurologic consequences of COVID-19,” said senior author Ziyad Al-Aly, MD, assistant professor of medicine at Washington University in St. Louis, Director of […]
