Altered protein shapes may explain differences in some brain diseases
Wednesday, Jul 3, 2013
It only takes one bad apple to spoil the bunch, and the same may be true of certain proteins in the brain. Studies have suggested that just one rogue protein (in this case, a protein that is misfolded or shaped the wrong way) can act as a seed, leading to the misfolding of nearby proteins. According to an NIH-funded study, various forms of these seeds — originating from the same protein — may lead to different patterns of misfolding that result in neurological disorders with unique sets of symptoms.
New Orthostatic Hypotension Treatment Reduces Symptoms Without Causing High Blood Pressure

A drug traditionally used to treat myasthenia gravis shows potential benefit for reducing symptoms of orthostatic hypotension without raising blood pressure when people lie down, according to results of a double-blind, controlled clinical trial.
Parkinson's Disease Is More Than a Brain Disorder
Monday, Sep 4, 2000
For many years, researchers have known that the movement problems associated with Parkinson's disease result from a loss of neurons that produce a nerve-signaling chemical called dopamine in one part of the brain. A new study suggests that Parkinson's disease (PD) also affects nerve endings that produce a related chemical, norepinephrine, in the heart. The finding improves understanding about how Parkinson's disease develops and may lead to a way of predicting the disorder and possibly even preventing it.
