Summary: Adult stem cells produced in the brain make only specialized kinds of connections and do not adapt to other functions. For instance, a neural stem cell originating in the brain cannot replace damaged cells in the spinal cord.
Summary: Researchers have identified a new markets making it possible to track brain stem cells for the first time.
Summary: Recent studies have helped explain how the immune systems affects neural connections and nerve cells.
Summary: Research suggests that intermittent nicotine treatment may reduce medication-induced dyskinesias. Smokers are 50% less likely to develop Parkinson's disease than the general population.
Summary: Relatives of patients with Parkinson's disease are more likely than others to develop symptoms of dementia. Researchers propose the presence of shared risk factors.
Summary: People with Parkinson's disease (PD) have a lower pain threshold than their peers. However, in a clinical study, levodopa increased the pain threshold of subjects with PD compared with healthy subjects who receive the same dose.
Summary: Two cell enzymes cooperate to prevent a break-down of mitochondria which could otherwise lead to Parkinson's disease.
Summary: Dementia is patients with Parkinson's disease is distinctly different from symptoms in patients with Alzheimer's. Parkinson's patients tend to have poor attention, while Alzheimer's patients have worse memory.
Summary: Scientists at Emory University have developed a computer model that simulates how the nervous system communicates with muscles to move muscles and control balance.
Summary: Mutations in the glucocerebrosidase (GBA) gene nearly triple the likelihood of developing Parkinson's disease and double the risk of onset before age 50.
