Researchers in Germany have found further evidence to support the idea that Parkinson’s could be an autoimmune disease. Using a stem cell model, they showed how immune cells attacked dopamine-producing cells derived from people with Parkinson’s disease but not from people without it. Dopamine is a chemical messenger that supports many important brain functions. These include functions that deal with...

Study provides insight into how dying neurons control eating behaviors of the brain microglia
July 23, 2018, The Mount Sinai Hospital A new Mount Sinai study, published July 23 in the journal Nature Neuroscience, provides important insight into how microglia, cells that form a branch of the immune system inside the brain, go about their job of clearing out dying and non-functional neurons—and how they sometimes mistakenly attack healthy neurons, an...

Paralyzed mice walk again after treatment restores neurons’ “Yin and Yang” balance
A spinal cord injury doesn’t need to be complete to cause paralysis – even with some nerves left intact, messages from the brain still don’t seem to get through. While investigating why that’s the case, researchers at the F.M. Kirby Neurobiology Center of Boston Children’s Hospital determined that a certain drug helps balance the Yin and Yang...

Strong sensitivity to bitter tastes tied to higher cancer risk
New research suggests that a raised sensitivity to bitter tastes might be a good predictor of cancer risk in women. Researchers are investigating the mysterious link between sensitivity to bitter tastes and the risk of cancer in women. A recent study has started to investigate the link between sensitivity to better tastes and the risk of cancer. It...

Treating dementia with the healing waves of sound
Ultrasound applied to the brain could help treat patients with dementia. TOHOKU UNIVERSITY Ultrasound waves applied to the whole brain improve cognitive dysfunction in mice with conditions simulating vascular dementia and Alzheimer’s disease. The research, conducted by scientists at Tohoku University in Japan, suggests that this type of therapy may also benefit humans. IMAGE: ULTRASOUND TREATMENTS COULD...
