Getting a good night’s sleep can be challenging, especially as we age. About half of all older adults report sleeping difficulties. This can make them more likely to experience physical or mental health conditions, memory problems, and falls, due to poor balance.

Like musical sounds, different states of mind are defined by distinct, characteristic waveforms, recognizable frequencies and rhythms in the electrical field of the brain. When the brain is alert and performing complex computations, the cerebral cortex, the wrinkled outer surface of the brain, thrums with cortical band oscillations in the gamma wavelength; in some neurological disorders like schizophrenia, these waves are out of tune and the rhythm is out of sync.

Once upon a time it was believed that greedy insurance companies were bad for patients - now they are a sign of the have's and have nots. A new analysis in Neurosurgery finds that brain tumor patients with private insurance have fewer medical complications and thus are in the hospital less than those who are on Medicaid or were uninsured between 2002 and 2011.

A new review looks at how the brain impacts the sequence of physical and emotional changes that occur as a person participates in sexually stimulating activities.
Experts note that the cerebral cortex region of the brain is involved in all three phases of the sexual pleasure cycle—wanting sex, having sex, and inhibiting sex—and each of these phases depends on distinct networks within the brain. It’s also clear that alterations in these brain networks are associated with sexual dysfunction.

ANN ARBOR, Mich. -- Doctors write millions of prescriptions a year for drugs to calm the behavior of people with Alzheimer's disease and other types of dementia. But non-drug approaches actually work better, and carry far fewer risks, experts conclude in a new report.
In fact, non-drug approaches should be the first choice for treating dementia patients' common symptoms such as irritability, agitation, depression, anxiety, sleep problems, aggression, apathy and delusions, say the researchers in a paper just published by the British Medical Journal.

Amyloid -- an abnormal protein whose accumulation in the brain is a hallmark of Alzheimer's disease -- starts accumulating inside neurons of people as young as 20, a much younger age than scientists ever imagined, reports a surprising new Northwestern Medicine study.
Scientists believe this is the first time amyloid accumulation has been shown in such young human brains. It's long been known that amyloid accumulates and forms clumps of plaque outside neurons in aging adults and in Alzheimer's.

A new study by a UT Dallas researcher challenges a long-accepted scientific theory about the role the hippocampus plays in our unconscious memory.
For decades, scientists have theorized that this part of the brain is not involved in processing unconscious memory, the type that allows us to do things like button a shirt without having to think about it.
But research by Dr. Richard Addante, a senior lecturer in the School of Behavioral and Brain Sciences, raises doubts about that.

75 percent of movies earn a net loss during their run in theaters. A new study finds that brain activity visible through electroencephalography (EEG) measures may be a much cheaper and more accurate way to predict the commercial success of movies.

Our brains generate a constant hum of activity: As neurons fire, they produce brain waves that oscillate at different frequencies. Long thought to be merely a byproduct of neuron activity, recent studies suggest that these waves may play a critical role in communication between different parts of the brain.
