The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Smoking makes it harder for brain blood flow to recover from long-term heavy drinking

Alcohol-use disorders (AUDs) can damage the brain, particularly the frontal and parietal cortices, although this damage is at least partially reversible with sustained abstinence from alcohol. Chronic smoking is extremely common among individuals with AUDs.

Building a bridge from Alzheimer's disease to diabetes and vice versa

Modern societies face the increasing burden of age-related diseases, in particular Alzheimer's disease (AD) and type 2 diabetes (T2D).

Discovery of major new treatment target in diseased arteries

Removing a single protein prevents early damage in blood vessels from triggering a later-stage, frequently lethal complication of atherosclerosis, according to research published online today in the journal Nature Medicine. By eliminating the gene for a signaling protein called cyclophilin A (CypA) from a strain of mice, researchers were able to provide complete protection against abdominal aortic aneurysm (AAA).

FDA approves Samsca tablets (tolvaptan) to treat hyponatremia

The U.S. Food and Drug Administration has approved Samsca tablets (tolvaptan) to treat hyponatremia, an abnormally low concentration of sodium in the blood.

FDA approves Avastin (bevacizumab) for treatment of glioblastoma multiforme

The U.S. Food and Drug Administration recently approved Avastin (bevacizumab) to treat patients with glioblastoma multiforme (GBM) when this form of brain cancer continues to progress following standard therapy.

Cell's split personality is a major discovery into neurological diseases

Researchers at the Université de Montreal (UdeM) and the Montreal Neurological Institute (MNI), McGill University have discovered that cells which normally support nerve cell (neuron) survival also play an active and major role in the death of neurons in the eye.

Brain cell mechanism for decision making also underlies judgment about certainty

Countless times a day people judge their confidence in a choice they are about to make -- that they now can safely turn left at this intersection, that they aren't sure of their answer on a quiz, that their hot coffee has cooled enough to drink.

MRI research may lead to new methods for diagnosing ADHD and other mental health disorders

Oregon Health & Science University researchers, along with scientists at Washington University in St. Louis, are uncovering new information about the mind by studying the brain while it is at rest. It is believed this research will one day provide new tools for diagnosing mental health disorders and monitoring the progress of treatments.

Children's activity levels not influenced by more PE time in school

Scheduling more physical education time in schools does not mean children will increase their activity levels, suggests new research that discovered those who got lots of timetabled exercise at school compensated by doing less at home while those who got little at school made up for it by being more active at home.

FDA approve Fanapt tablets (iloperidone) to treat adults with schizophrenia

The U.S. Food and Drug Administration has approved Fanapt tablets (iloperidone) to treat adults with schizophrenia, a chronic, severe and disabling brain disorder.

Listening to music can change the way you judge facial emotions

It is often said that music is the language of emotions. Simply, we are moved by music. But can these musically induced emotions arising through the auditory sense influence our interpretation of emotions arising through other senses (eg visual)?

Discovery of gene key to Alzheimer's-like reversal

A team led by researchers at MIT's Picower Institute for Learning and Memory has now pinpointed the exact gene responsible for a 2007 breakthrough in which mice with symptoms of Alzheimer's disease regained long-term memories and the ability to learn

Research shows right from the beginning babies are active learners

A new study from Northwestern University shows what many mothers already know: their babies are a lot smarter than others may realize.

Neuroglobin making gene tied to Alzheimer's

Of dozens of candidates potentially involved in increasing a person's risk for the most common type of Alzheimer's disease that affects more than 5 million Americans over the age of 65, one gene that keeps grabbing Johns Hopkins researchers' attention makes a protein called neuroglobin.

Three genes play a role in breast cancer's spread to the brain

New research led by investigators at Memorial Sloan-Kettering Cancer Center (MSKCC) identifies three genes that specifically mediate the metastasis, or spread, of breast cancer to the brain and illuminates the mechanisms by which this spread occurs. The study was published online today in Nature.

Estrogen plays a key role in how the brain processes sounds

The findings, published in today's issue of The Journal of Neuroscience, show for the first time that a sex hormone can directly affect auditory function, and point toward the possibility that estrogen controls other types of sensory processing as well.

Potential molecular target for new schizophrenia treatments

A study on schizophrenia has implicated machinery that maintains the flow of potassium in cells and revealed a potential molecular target for new treatments. Expression of a previously unknown form of a key such potassium channel was found to be 2.5 fold higher than normal in the brain memory hub of people with the chronic mental illness and linked to a hotspot of genetic variation.

New method a dream come true for sleep apnea patients

Researchers from the University of Sydney have found the first hard evidence that the special masks doctors prescribe to patients with sleep apnea - a disorder that can cause interrupted breathing leading to choking and even death while asleep - actually work.

Protein kinase JNK1 identified as treatment target for retinopathy in premature babies

Results of a study in mice by researchers at the University of California, San Diego strongly suggest that the protein kinase JNK1 plays a key role in the development of retinopathy in premature infants.

Episodes of delirium accelerate cognitive decline and memory loss in Alzheimer's patients

Delirium often develops in elderly patients during hospitalization or serious illness, and this acute state of confusion and agitation has long been suspected of having ties to Alzheimer's disease and other dementias.
