Diazepam effects nerve cells in the brain reward system

Addictions to medicines and drugs are thought to develop over a relatively long period of time. The process involves both structural and functional changes in brain nerve cells that are still poorly understood.

UT Southwestern discovery may lead to new drug-abuse treatments

Increased connections among brain cells caused by excessive drug use may represent the body's defense mechanism to combat addiction and related behaviors, scientists at UT Southwestern Medical Center have found.

Potential new targets for antidepressants

The news about antidepressant medications over the past several years has been mixed. The bad news from large multicenter studies such as STAR*D is that current antidepressant medications are effective, but not as effective as one might hope. Thus, there is a significant need for new treatment mechanisms for depression. On that front, there has been mixed news as well.

New technique offers hope for stroke sufferers

If a stroke patient doesn't get treatment within approximately the first three hours of symptoms, there's not much doctors can do to limit damage to the brain.

Middle ear infections in childhood linked to obesity later in life

Researchers are reporting new evidence of a possible link between a history of moderate to severe middle ear infections in childhood and a tendency to be overweight later in life. Their study suggests that prompt diagnosis and treatment of middle ear infections - one of the most common childhood conditions requiring medical attention - may help fight obesity in some people.

Chronic ear infections linked to increased preference for high-fat foods

Ear infections are a painful rite of passage for many children. New research suggests the damage caused by chronic ear infections could be linked to people's preference for fatty foods, which increases their risk of being overweight as they age. Scientists from around the country presented their findings on this unexpected connection at the American Psychological Association's 116th Annual Convention here Thursday.

Molecular switch provides insights into a form of altered brain activity occurring in schizophrenia

People with schizophrenia have an alteration in a pattern of brain electrical activity associated with learning and memory. Now, researchers from the National Institutes of Health and Sweden's Karolinska Institute have identified in mouse brain tissue a molecular switch that, when thrown, increases the strength of this electrical pattern. The researchers found that adding the brain chemical Neuregulin-1 to the brain tissue boosted the electrical signals that the tissue generated.

Window of opportunity for newly diagnosed diabetics

According to health researchers in the U.S., people who lose weight soon after being diagnosed with type 2 diabetes are far more likely to reach satisfactory blood glucose and blood pressure goals.

Medulloblastoma in children - two studies find clues to treatment

Medulloblastoma is one of the most common and most malignant brain tumours among children and teenagers. These tumours grow very rapidly, and fifty percent of patients in the long term die from the condition. The details of the processes that lead to the growth of these tumours have remained unknown until now.

Losing weight after diabetes diagnosis prevent related disease

People who lose weight soon after a diagnosis of type 2 diabetes have better control of their blood pressure and blood sugar, and are more likely to maintain that control even if they regain their weight, according to a Kaiser Permanente study published online in Diabetes Care, the American Diabetes Association journal.
