People who will develop dementia may begin to lose awareness of their memory problems two to three years before the actual onset of the disease, according to a new study published in the August 26, 2015, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study also found that several dementia-related brain changes, or pathologies, are associated with the decline in memory awareness.

Only half of brain cancers actually start in the brain. The rest – as in the case of former president Jimmy Carter – are metastatic tumors from cancer that originated elsewhere in the body.
Newly published research from the Rowan University School of Osteopathic Medicine explains why up to half of older adults who undergo general anesthesia develop postoperative delirium – the sudden onset of confusion, aggression or agitated behavior that could progress to dementia.
While some research suggests that a diet high in omega-3 fatty acids can protect brain health, a large clinical trial by researchers at the National Institutes of Health found that omega-3 supplements did not slow cognitive decline in older persons. With 4,000 patients followed over a five-year period, the study is one of the largest and longest of its kind. It was published today in the Journal of the American Medical Association.
Commonly used antidepressant drugs change levels of a key signaling protein in the brain region that processes both pain and mood, according to a study conducted at the Icahn School of Medicine at Mount Sinai and published August 24 in the Proceedings of the National Academy of Sciences (PNAS).
Researchers at NYU Langone Medical Center have found how even brief exposure to sudden sounds or mild trauma can form permanent, long-term brain connections, or memories, in a specific region of the brain. Moreover, the research team, working with rats, says it was able to chemically stimulate those biological pathways in the locus coeruleus — the area of the brain best known for releasing the “fight or flight” hormone noradrenaline — to heighten and improve the animals’ hearing.
The wriggling and writhing of worms may hold clues to the inner workings of our brains, according to scientists at the MRC’s Clinical Sciences Centre at Imperial College London. The researchers have developed a pioneering tool to analyse a worm’s posture as it wriggles, and will use the tool to investigate how exactly the worm’s brain controls its movements.

Testing the saliva of healthy older people for the level of the stress hormone cortisol may help identify individuals who should be screened for problems with thinking skills, according to a study published in the August 19, 2015, online issue of Neurology®, the medical journal of the American Academy of Neurology.
If a pregnant woman with high blood pressure and no history of headache suddenly develops a headache that quickly gets worse, she could be at risk for pregnancy complications, including preeclampsia, which put both the mother and fetus at risk.
A new study in Journal of Neurophysiology uses a novel approach to identify potential drug targets for treating fibromyalgia, This study is published ahead-of-print.
You see a man at the grocery store. Is that the fellow you went to college with or just a guy who looks like him? It turns out that a tiny spot in the brain has the answer.
By early childhood, the sight regions of a blind person’s brain respond to sound, especially spoken language, a Johns Hopkins University neuroscientist has found
People being treated for bipolar disorder and other psychiatric illnesses are at greater risk of attempting suicide, but physicians may now have tools to predict which of those individuals will attempt it and intervene early to prevent such tragedies from occurring.

For the first time, scientists have seen evidence of where the brain records the time and place of real-life memories.
Scientists have revealed never-before-seen details of how our brain sends rapid-fire messages between its cells. They mapped the 3-D atomic structure of a two-part protein complex that controls the release of signaling chemicals, called neurotransmitters, from brain cells. Understanding how cells release those signals in less than one-thousandth of a second could help launch a new wave of research on drugs for treating brain disorders.
Findings from Nationwide Children’s Hospital physicians demonstrate that headaches increase in fall in children, a trend that may be due to back-to-school changes in stress, routines and sleep.
Researchers at Rush University Medical Center are exploring a new therapy using stem cells to treat spinal cord injuries within the first 14 to 30 days of injury. Rush is only the second center in the country currently studying this new approach.
A bomb blast or a rough tackle can inflict serious brain damage. Yet at the time of impact, these injuries are often invisible. To detect head trauma immediately, a team of researchers has developed a polymer-based material that changes colors depending on how hard it is hit. The goal is to someday incorporate this material into protective headgear. They will describe their approach at the 250th National Meeting & Exposition of the American Chemical Society.
New research from Washington University in St. Louis has identified a novel learning and memory brain network that processes incoming information based on whether it’s something we’ve experienced previously or is deemed to be altogether new and unknown, helping us recognize, for instance, whether the face before us is that of a familiar friend or a complete stranger.
A new study suggests children with multiple sclerosis (MS) who exercise regularly may have a less active disease. The research is published in the August 12, 2015, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Determining whether or not an individual has dementia and to what degree is a long and laborious process that can take an experienced professional such as a clinician about four to five hours to complete. A leading neuroscientist at FAU has developed a way for a layperson to do this in three to five minutes with results that are comparable to the “gold standard” dementia tests used by clinicians today.

Researchers at McGill University have clearly identified, for the first time, the specific parts of the brain involved in decisions that call for delayed gratification. They demonstrated that the hippocampus (associated with memory) and the nucleus accumbens (associated with pleasure) work together in making critical decisions of this type, where time plays a role.
A team of scientists believe they have shown that memories are more robust than we thought and have identified the process in the brain, which could help rescue lost memories or bury bad memories, and pave the way for new drugs and treatment for people with memory problems.
Researchers at the University of Virginia (UVa) examined the number and severity of subconcussive head impacts sustained by college football players over an entire season during practices and games. The researchers found that the number of head impacts varied depending on the intensity of the activity.
Researchers at McGill University have discovered that to learn new motor skills, neurons within the cerebellum engage in elegant, virtually mathematical, computations to quickly compare expected and actual sensory feedback. They then quickly readjust, changing the strength of connections between other neurons to form new patterns in the brain in order to accomplish the task at hand.
