Diagnosing neurological diseases before symptoms occur
Cleveland Clinic has launched a landmark study to better understand why millions of people around the world suffer from brain diseases, with the goal of pinpointing disease biomarkers early, well before clinical symptoms present themselves.

Injections of zika virus destroys brain tumors
In both the mice and organoids, cytokines suppressed tumor growth after treatment, and defense cells migrated to the brain region affected by the tumor, alerting the immune system to its existence.

Does ethnicity affect brain tumour survival?
New research has pinpointed ethnicity as a potential factor in brain tumour survival. A UK study showed that white British people who have been diagnosed with a malignant primary brain tumour appear to have an increased one-year mortality than patients from at least four other ethnic groups.

Quantum sensors for next-gen brain-computer interfaces
Connecting the brain with a machine has been a powerful dream of mankind. What used to be science fiction, from the Borg in Star Trek to the Matrix, has become mainstream thanks to Elon Musk and Mark Zuckerberg who have put their entrepreneurial commitments into the area of neurotechnology. Recently, Professor Surjo R. Soekadar outlined current and upcoming applications of brain-computer…

Nanoparticles to help cross the blood-brain barrier
Treating diseases such as Alzheimer’s or Parkinson’s is a challenge because drugs have to be able to cross the blood–brain barrier. As a result, the doses administered must be high and only a small fraction reaches the brain, which can lead to significant systemic side effects.

Scientists identify the cause of Alzheimer’s progression in the brain
For the first time, researchers have used human data to quantify the speed of different processes that lead to Alzheimer’s disease and found that it develops in a very different way than previously thought. Their results could have important implications for the development of potential treatments.

The 'thermostat' that prevents our brain from overheating
The mechanisms by which the body measures temperature and regulates its own body heat are vital, but still poorly understood. The discovery of the first heat sensor on nerve cells in the skin, for which the U.S. molecular biologist David Julius received this year's Nobel Prize for Medicine, was therefore pioneering. However, a very similar heat sensor, the protein TRPM2, is active not only in the…

Infrared light helmet might aid dementia patients
Researchers at Durham University are working on a new infrared light therapy that might have the potential to help people with dementia. In the approach, people wear a specially adapted helmet which delivers infrared light deep into the brain for six-minutes per treatment. This stimulates mitochondria that generate most of the chemical energy needed to power the biochemical reaction in the…

Stroke: Women remain underrepresented in clinical trials
A new study shows that women are underrepresented in stroke clinical trials relative to the number who have strokes in the general population. The research is published in Neurology, the medical journal of the American Academy of Neurology. “Making sure there are enough women in clinical studies to accurately reflect the proportion of women who have strokes may have implications for future…

High-definition MRI reveals previously hidden territory of the human brain
Neuroscientists at Technische Universität Dresden discovered a novel, non-invasive imaging-based method to investigate the visual sensory thalamus, an important structure of the human brain and point of origin of visual difficulties in diseases such as dyslexia and glaucoma. The new method could provide an in-depth understanding of visual sensory processing in both health and disease in the near…

‘Blue spot’ in the brain helps detecting Alzheimer’s early
A miniscule area in the brain, known as the locus coeruleus (LC), or blue spot, can help to identify an increased risk of Alzheimer’s disease at a very early stage. The LC is hidden deep in the brainstem and can only be detected with advanced MRI equipment. Heidi Jacobs (Maastricht University/Harvard Medical School) used MRI scans to show that the tau protein can begin to spread in the LC three…
