BETHESDA, MD — A number of drugs have been shown to have neuroprotective benefits in animal models of TBI. When studies have moved on to human subjects, however, most have had poor results.

WASHINGTON — A new survey of teen drug use shows that, while alcohol use continues its long-term decline, marijuana use has surprisingly spiked, suggesting a changing attitude among teens about the dangers of its regular use. The survey, officials said, can act as a road map for prevention efforts.

BETHESDA, MD — With all of the attention given traumatic brain injury in recent years, it can be easy to forget that this is still a nascent area of medical science. It took six years of fighting in Afghanistan and Iraq for the military leaders to realize the impact TBI — especially the cumulative effects of multiple mild TBI — was having on servicemembers.

BETHESDA, MD — Many men are receiving curative therapy for prostate cancer who would be better served by more passive, observational treatment, according to a panel of experts convened by the NIH.

BETHESDA, MD —A problem with insomnia, one of the shared symptoms of TBI and PTSD, sometimes can be overshadowed by what seem to be more serious, immediate symptoms. For those suffering from sleep disorders, however, exhaustion can quickly take over their lives.

NIH researchers are enrolling multiple generations of patients in a landmark study designed to identify the early warning signs of heart disease among African-Americans. The new feasibility study will enroll children and grandchildren of African-American adults participating in the ongoing Jackson Heart Study in Jackson,  MS.

WASHINGTON — While there is evidence that cognitive rehabilitation therapy (CRT) has a positive impact on TBI, it is not sufficient to develop guidelines on how to apply this type of therapy to specific patients, according to a recent report from the Institute of Medicine (IoM).

WASHINGTON — A cutting-edge scanner that combines a whole-body, simultaneous positron emission topography (PET) and magnetic resonance imaging (MRI) could be invaluable in helping them better understand what changes are occurring in the brains of those suffering from TBI and PTSD, federal scientists said.

WASHINGTON — Diet impacts far more than waistlines and the risk of obesity. In fact, the military has been paying close attention to not only the role of nutrition in maintaining physical health, but also how it relates to psychological health issues such as suicide and even TBI.

BETHESDA, MD — Recent projects being overseen or funded at NIH hope to shed light on the biology of traumatic brain injury (TBI) and give physicians and future researchers better tools to understand, diagnose and treat the condition.
