Promising target for treating brain tumors in children

Findings published in Oncotarget offer new hope for children with highly aggressive brain tumors like atypical teratoid/rhabdoid tumor (AT/RT) and medulloblastoma. Previously, the authors of the study have shown that an experimental drug that inhibits polo-like kinase 4 (PLK4) stopped pediatric brain tumor growth in vitro. Now, they have demonstrated its success in an animal model – the drug…

News • Study asks neurosurgeons

How old is too old to perform brain surgery?

People sometimes joke that easy tasks are “not brain surgery.” But what happens when it actually is brain surgery? How old is too old to be a neurosurgeon? In a new Mayo Clinic Proceedings study, most neurosurgeons disagreed with an absolute age cutoff, but half favored additional testing for neurosurgeons 65 and older. Some professions, including commercial pilots, FBI agents and air traffic…

Mapping brain connectivity with MRI may predict cardiac arrest survival

A new study led by Johns Hopkins researchers found that measures of connectivity within specific cerebral networks were strongly linked to long-term functional outcomes in patients who had suffered severe brain injury following a cardiac arrest. A description of the findings, published in October in the journal Radiology, suggests that mapping and measuring such connectivity may result in highly…

Nanosensors uncloak the mysteries of brain chemistry

Nanosensors are incredible information-gathering tools for myriad applications, including molecular targets such as the brain. Neurotransmitter molecules govern brain function through chemistry found deep within the brain, so University of California, Berkeley researchers are developing nanosensors to gain a better understanding of exactly how this all plays out. During the AVS 64th…

Risks – and benefits – of the Alzheimer’s gene

Scientists drilling down to the molecular roots of Alzheimer’s disease have encountered a good news/bad news scenario. A major player is a gene called TREM2, mutations of which can substantially raise a person’s risk of the disease. The bad news is that in the early stages of the disease, high-risk TREM2 variants can hobble the immune system’s ability to protect the brain from amyloid beta,…

Zika virus could be used to treat brain cancer

Recent outbreaks of Zika virus have revealed that the virus causes brain defects in unborn children. But researchers from Washington University School of Medicine in St. Louis and the University of California, San Diego report that the virus could eventually be used to target and kill cancer cells in the brain.

No health without brain health

A largely aged population is already a reality in some countries, and this will become a worldwide problem by 2047, when the number of the Earth’s old people is likely to surpass the number of young people.

Stroke is over (if you want it)

The fourth World Brain Day (July 22) revolves around stroke – how to detect it, how to prevent it, how to treat it. Raad Shakir, president of the World Federation of Neurology (WFN), seizes the opportunity to raise awareness about a disease that is becoming more common globally – but also preventable to a large extent.

$20 million lifestyle intervention trial to prevent cognitive decline

The Alzheimer's Association announced the launch of a $20 million U.S. two-year clinical trial to test the ability of a multi-dimensional lifestyle intervention to prevent cognitive decline and dementia in 2,500 older adults with no current cognitive symptoms but who are at increased risk for later cognitive decline. The announcement was made at the 2017 Alzheimer's Association International…

New understanding for autism through eye tracking

New research has uncovered compelling evidence that genetics plays a major role in how children look at the world and whether they have a preference for gazing at people’s eyes and faces or at objects. The discovery by researchers at Washington University School of Medicine in St. Louis and Emory University School of Medicine in Atlanta adds new detail to understanding the causes of autism…

When the internal clock is out of order

Persons suffering from schizophrenia have a different perception of time than healthy individuals, a new study finds. There is far more variation in the way that a time interval is perceived by people with schizophrenic disorders than by those who do not have the condition. Patients with schizophrenia are also less precise when it comes to judging the temporal order of events.
