Shortness of breath can be a serious cardiac symptom

Now, researchers at Cedars-Sinai Medical Center have found that patients with shortness of breath can have a higher risk of dying from cardiac disease than patients without symptoms, and even than patients with typical cardiac pain.

Functional diffusion map to help predict brain tumor outcomes

A special type of MRI scan that measures the movement of water molecules through the brain can help doctors determine halfway through treatment whether it will successfully shrink the tumor or a patient's cancer will continue to grow, a new study shows.

How the brain tracks time is essential to understanding all its functions

The brain is a "time machine," assert Duke neuroscientists Catalin Buhusi and Warren Meck. And understanding how the brain tracks time is essential to understanding all its functions. The brain's internal clocks coordinate a vast array of activities from communicating, to orchestrating movement, to getting food, they said.

Environment is a major factor influencing the success of the addiction recovery

New research in monkeys suggests that, although living in an "enriched" environment can make someone less vulnerable to abusing cocaine, once started, extended drug abuse can eliminate the social advantage the abuser originally had.

Scientists say there is less white matter in the frontal lobes of those who struggle with focusing

When it comes to focusing on a task amid distractions, some folks more than 60 years old are as mentally sharp as 22-year-olds. Others struggle. Researchers at the Beckman Institute for Advanced Science and Technology at the University of Illinois at Urbana-Champaign have shed some light on why that is.

Link between emotional impairment and poor cognition in children with bipolar disorder

Using functional magnetic resonance imaging, Pavuluri and her colleagues examined the brain activity of teens while they were performing certain mental tasks. The researchers scanned the brains of 10 unmedicated bipolar patients with normal mood and compared them with 10 healthy subjects of the same age and gender.

Patients with head and neck cancer may be spared the risk and expense of surgery by undergoing a CT scan

Researchers with the UF Shands Cancer Center have identified criteria doctors can use to evaluate CT scans four weeks after patients undergo initial treatment. If these criteria are met, there is a 94 percent likelihood a patient's lymph nodes are cancer free, said Stanley L. Liauw, M.D., a resident in radiation oncology.

Aβ and Fyn cooperate to cause Alzheimer-like changes in the brain

Reporting in two companion papers in the October 19 issue of the Journal of Neuroscience, investigators from the Gladstone Institute of Neurological Disease show in genetically engineered mouse models of the disease that the accumulation of Alzheimer-related neurotoxic amyloid-beta (Aâ) peptides can deplete key proteins in a specific memory center of the brain.
