Protein linked to sex differences in age-related dopamine neuron loss — ScienceDaily


[ad_1] It is not every day that scientists come across a phenomenon so fundamental that it is observed across fruit flies, rodents and humans. In a paper published today in Aging Cell, neuroscientists from the University of Pittsburgh Schools of the Health Sciences discovered that a single protein — a glutamate transporter on the membrane […]

New model may explain the mystery of asymmetry in Parkinson’s disease — ScienceDaily


[ad_1] Parkinson’s disease (PD) is characterized by slowness of movement and tremors, which often appear asymmetrically in patients. The new model of PD described in this review article published in the Journal of Parkinson’s Disease may explain these perplexing asymmetrical motor symptoms and other known variations such as different degrees of constipation and sleep disorders. […]

Impaired drainage also may play a role in Alzheimer’s in people — ScienceDaily


[ad_1] Experimental Alzheimer’s drugs have shown little success in slowing declines in memory and thinking, leaving scientists searching for explanations. But new research in mice has shown that some investigational Alzheimer’s therapies are more effective when paired with a treatment geared toward improving drainage of fluid — and debris — from the brain, according to […]

Awakening ‘ghosts’ in patients with Parkinson’s, a powerful diagnostic tool — ScienceDaily


[ad_1] Scientists are developing a completely new ‘brain stress test’ for evaluating the mental status of patients with Parkinson’s disease, the second most prevalent neurodegenerative disease worldwide. It involves awakening the ‘ghosts’ hidden in specific networks of the brain to predict the onset of hallucinations. “We’re developing something similar to a cardiac stress test, but […]

DR MICHAEL MOSLEY: The cutting-edge medicine that has helped save hero soldiers like Ben Parkinson 


[ad_1] Reading Ben Parkinson’s extraordinary story, the first part of which is serialised in today’s Mail, stirred up some powerful memories. Ten years ago I spent time in Afghanistan making a documentary about medicine on the frontline, about the courage of soldiers such as Ben as well as new developments in trauma medicine. The survival […]
