By examining more than 3,600 postmortem brains, researchers at Mayo Clinic's campuses in Jacksonville, Florida, and Rochester, Minnesota, have found that the progression of dysfunctional tau protein drives the cognitive decline and memory loss seen in Alzheimer's disease.
Researchers at the Perelman School of Medicine at the University of Pennsylvania describe the first set of genes important in learning in a zebrafish model in the journal Neuron this week.
New research from Rockefeller University identifies a molecular cascade known as the contact system, which may provide opportunities for early diagnosis of Alzheimer's disease through simple blood tests.
The strategies for living a long and healthy life are well known and relatively simple, if not always easily executed: Maintain an appropriate weight. Eat the right foods. Exercise. Limit stress. Somewhat less has been known, or said, about ways to keep the mind fit for the duration. But that’s changing.
Having a strong sense that your life has meaning and direction may make you less likely to develop areas of brain damage caused by blockages in blood flow as you age.
It’s not all in your head. Brain injuries from sports are a steady unease for athletes.
A research team at UC San Francisco has discovered an RNA molecule called Pnky that can be manipulated to increase the production of neurons from neural stem cells.
A new study by UC Berkeley and UC San Francisco researchers finds that giving a drug that changes the neurochemical balance in the prefrontal cortex of the brain causes a greater willingness to engage in prosocial behaviors, such as ensuring that resources are divided more equally.
New research is changing long-held ideas of how our minds age, painting a richer picture of different cognitive skills peaking across a lifetime, with at least one — vocabulary — peaking at a time when many are considering retirement.
Researchers have developed a new scoring system to help determine which elderly people may be at a higher risk of developing the memory and thinking problems that can lead to dementia, according to a new study published in the March 18, online issue of Neurology®, the medical journal of the American Academy of Neurology.
A University of Wyoming faculty member is part of a research team that created a method, using laser, to better decode complex neural circuits in the brain -- a process that eventually may help unlock the mysteries of epilepsy, autism spectrum disorder and Alzheimer’s in humans.
Findings may relate to anesthetic neurotoxicity in children and could lead to more targeted and safer concentration levels.
Intentionally recalling memories may lead us to forget other competing experiences that interfere with retrieval, according to a study published today. In other words, the very act of remembering may be one of the major reasons why we forget.
Scientists at The University of Manchester have made an important new discovery about the brain’s immune system that could lead to potential new treatments for stroke and other related conditions.
New York University researchers have devised a computer model to explain how a neural circuit learns to classify sensory stimuli into discrete categories, such as “car vs. motorcycle.” Their findings, which appear in the journal Nature Communication, shed new light on the brain processes underpinning judgments we make on a daily basis.
Two groups have recently made strides with amyloid beta (aβ), the supposed main villain in Alzheimer’s disease. But while one group is tackling Alzheimer’s by reducing aβ, the other is tackling multiple sclerosis (MS) by using aβ.
Researchers at MIT have developed a method to stimulate brain tissue using external magnetic fields and injected magnetic nanoparticles — a technique allowing direct stimulation of neurons, which could be an effective treatment for a variety of neurological diseases, without the need for implants or external connections.
UCLA researchers have provided the first evidence that a simple blood test could be developed to confirm the presence of beta amyloid proteins in the brain, which is a hallmark of Alzheimer’s disease.
Queensland scientists have found that non-invasive ultrasound technology can be used to treat Alzheimer’s disease and restore memory.
A new study reveals an important connection between dozens of genes that may contribute to autism, a major step toward understanding how brain development goes awry in some individuals with the disorder.
Findings could help shed light on Alzheimer's, Parkinson's, ALS and other diseases.
Discovery has implications for understanding epilepsy.
A new study led by UNC researchers identifies both where in the brain and how a protein in the brain, called Neuropeptide Y or NPY, can act to suppress binge alcohol drinking. These findings suggest that restoring NPY may be useful for treating alcohol use disorders and may also protect some individuals from becoming alcohol dependent.
People with anorexia nervosa and with body dysmorphic disorder have similar abnormalities in their brains that affect their ability to process visual information, a new UCLA study reveals.
