Insights into Parkinson's balance problems

In PD, disorganized sensorimotor signals cause muscles in the limbs to contract, such that both a muscle promoting a motion and its antagonist muscle are Read more

Cajoling brain cells to dance

“Flicker” treatment is a striking non-pharmaceutical approach aimed at slowing or reversing Alzheimer’s disease. It represents a reversal of EEG: not only recording brain waves, but reaching into the brain and cajoling cells to dance. One neuroscientist commentator called the process "almost too fantastic to believe." With flashing lights and buzzing sounds, researchers think they can get immune cells in the brain to gobble up more amyloid plaques, the characteristic clumps of protein seen in Read more

Moving urology beyond the PSA test

The PSA (prostate specific antigen) blood test has been criticized for years for driving men to seek biopsies and then definitive treatment for slow-growing cancers that may not pose a danger.

At the recent AUA meeting in New Orleans, urologist Martin Sanda presented results from research on tests that could allow the urology field to move beyond the PSA test as it is now. Winship magazine’s cover story has more on this topic.

Martin Sanda, MD is director of Winship Cancer Institute’s Prostate Cancer Program and chair of urology at Emory University School of Medicine

Right now, only about a sixth of men who have a biopsy based on the results of a PSA test have something that doctors agree should be called a cancer (a tumor with a Gleason score of seven or higher).

Sanda described studies on a urine test that could double that specificity, possibly eliminating unnecessary biopsies for many men. Read more
