Smoking interferes with neurocognitive recovery during abstinence from alcohol

Smoking interferes with neurocognitive recovery during abstinence from alcohol

Numerous studies have shown that individuals with an alcohol use disorder perform worse than those without one on multiple neurocognitive domains of function following detoxification from alcohol, although the level of impairment can vary widely among individuals. A new study of the degree of neurocognitive recovery in treatment-seeking alcohol dependent individuals (ALC) — with varied degrees of smoking status — during the first eight months of sustained abstinence from alcohol has found that smoking status influenced the rate and level of recovery Continue reading

Resetting the circadian clock: Shift workers might want to skip high-iron foods at night

Workers punching in for the graveyard shift may be better off not eating high-iron foods at night so they don’t disrupt the circadian clock in their livers. Continue reading

See-through sensors open new window into the brain

See-through sensors open new window into the brain

Developing invisible implantable medical sensor arrays, a team of University of Wisconsin-Madison engineers has overcome a major technological hurdle in researchers’ efforts to understand the brain. The team described its technology, which has applications in fields ranging from neuroscience to cardiac care and even contact lenses, in the Oct. 20 issue of the online journal Nature Communications Continue reading

Scientists sniff out unexpected role for stem cells in the brain

Scientists sniff out unexpected role for stem cells in the brain

For decades, scientists thought that neurons in the brain were born only during the early development period and could not be replenished. More recently, however, they discovered cells with the ability to divide and turn into new neurons in specific brain regions. The function of these neuroprogenitor cells remains an intense area of research Continue reading

An end to needle phobia: Device could make painless injections possible

An end to needle phobia: Device could make painless injections possible

Imagine no tears during infant vaccines and no fear of the needle for those old enough to know what’s coming. Such painless injections could be possible with a device that applies pressure and vibration while the needle is inserted in the skin, according to a study presented at the ANESTHESIOLOGY™ 2014 annual meeting Continue reading

Intracranial stents: More strokes than with drug treatment alone

Intracranial stents: More strokes than with drug treatment alone

The risk of having another stroke is higher if patients, after dilation of their blood vessels in the brain, not only receive clot-inhibiting drugs, but also have small tubes called stents inserted. However, studies have provided no hint of a benefit from stenting, which is also referred to with the abbreviation “PTAS.” This is the conclusion reached in the rapid report of the German Institute for Quality and Efficiency in Health Care (IQWiG), as published on 9 October 2014. Stents are supposed to prevent restenosis Blood vessels in the brain that are narrowed or blocked can cause stroke. Continue reading
