Hormone modulating therapy (HMT) used for the treatment of breast cancer was associated with a 7% lower risk of developing Alzheimer's disease and related dementias later in life, according to a new study.

Rigorous exercise before bed has long been discouraged, but researchers have now found short bursts of light activity can lead to better sleep. Rigorous exercise before bed has long been discouraged, but University of Otago researchers have found short bursts of light activity can lead to better sleep. In a world first study, published in

For the first time, scientists have found that sleep can be detected by patterns of neuronal activity just milliseconds long, 1000 times shorter than a second, revealing a new way to study and understand the basic brain wave patterns that govern consciousness. Sleep and wake: they're totally distinct states of being that define the boundaries

A new, large study confirms earlier findings that children with an autistic sibling have a 20% chance of being autistic themselves. Siblings of autistic children have a 20% chance of being autistic themselves -- about seven times higher than the rate in infants with no autistic siblings. That's the key finding of a new paper

It's been long established that certain men become aggressive when they see their manhood as being threatened. When does this behavior emerge during development --a nd why? A new study shows that adolescent boys may also respond aggressively when they believe their masculinity is under threat -- especially boys growing up in environments with rigid

Researchers reveal how a gene called SH2B1 works in the brain to regulate food intake. Obesity is a complicated condition, caused by a combination of genetics, the food environment, behavior, and other factors. For millennia, getting enough food to survive and thrive was difficult. For most people, it's now as easy as opening a refrigerator.

Propofol, a drug commonly used for general anesthesia, induces unconsciousness by disrupting the brain's normal balance between stability and excitability. Propofol, a drug commonly used for general anesthesia, derails the brain's normal balance between stability and excitability. There are many drugs that anesthesiologists can use to induce unconsciousness in patients. Exactly how these drugs cause

A recent study identified beta frequency neural activity in the anterior cingulate cortex (ACC) of the brain's frontal lobe as the key neural signature underlying processes associated with recognizing rewards and determining subsequent choices and, thus, shaping future behaviors. As parents, teachers and pet owners can attest, rewards play a huge role in shaping behaviors

Scientists investigating Alzheimer's disease have determined the structure of molecules within a human brain. Their study describes how scientists used cryo-electron tomography, guided by fluorescence microscopy, to explore deep inside an Alzheimer's disease donor brain. This gave 3-dimensional maps in which they could observe proteins within the brain. Scientists investigating Alzheimer's disease have determined the

Toddlers engage more regions of their brains around 16-months to help them develop important cognitive skills enabling them to follow simple instructions and control impulses. Findings from the study suggests 16 months is a critical period for brain development. Toddlers engage more regions of their brains around 16-months to help them develop important cognitive skills

People tend to become less narcissistic as they age from childhood through older adulthood. However, differences among individuals remain stable over time -- people who are more narcissistic than their peers as children tend to remain that way as adults, the study found. People tend to become less narcissistic as they age from childhood through

Investigators analyzing the potential cognitive effects of antidiabetic medications in records of more than 1.5 million patients with type 2 diabetes mellitus (T2DM) found risks of dementia and Alzheimer's disease (AD) were significantly lower in patients treated with metformin and sodium glucose co-transporter-2 inhibitors (SGLT-2i) compared to other antidiabetic drugs. Investigators analyzing the potential cognitive
