Potential new treatment pathway for Parkinson's

In the vast majority of Parkinson's disease (PD) patients, the disorder arises not because of a genetic defect, but because some external insult triggers the death of dopamine-producing neurons.

New insight into neural stem cells

Scientists have discovered that adult neural stem cells, which exist in the brain throughout life, are not a single, homogeneous group.

Exercise good for those brain cells

According to Swedish researchers exercise may stimulate the production of new brain cells in the area of the brain that is important to memory and learning.

Exercise stimulates the production of new brain cells

Exercise has a similar effect to antidepressants on depression. This has been shown by previous research. Now Astrid Bjornebekk at Karolinska Institutet has explained how this can happen: exercise stimulates the production of new brain cells.

Mothers' second-hand smoke exposure while pregnant linked to children's ADHD

Children whose mothers were exposed to second-hand smoke while they were pregnant have more symptoms of serious psychological problems compared to the offspring of women who had no prenatal exposure to smoke, according to a new University of Washington study.

Early exposure to iron and later exposure to herbicide paraquat may accelerate age-related neurodegeneration

Exposure to iron during the first weeks of life in combination with exposure later in life to a common herbicide may contribute to the subsequent degeneration of brain cells associated with the onset of Parkinson's disease (PD), according to a new study in mice.

Link between levels of urate in the blood and risk of Parkinson's disease

In a new, large-scale, prospective study exploring the link between levels of urate in the blood and risk of Parkinson's disease, researchers from the Harvard School of Public Health (HSPH) have found that high levels of urate are strongly associated with a reduced risk of the disease.

Do common treatments for ADHD increase risk of drug abuse?

Parents, doctors, and others have wondered whether common treatments for attention-deficit hyperactivity disorder (ADHD) inadvertently predispose adolescents to future drug abuse.

Researchers use 'genomic pathway' to predict Parkinson's

A new Mayo Clinic study provides strong evidence that the joint effects of common DNA variations in several genes that encode proteins within a well-defined biological pathway largely explain why some persons get Parkinson's disease while others don't, and even predict with great accuracy at what age people might develop their first symptoms.

Isradipine may slow Parkinson's

Gloria E. Meredith, Ph.D., collaborated with D. James Surmeier, Ph.D. and other scientists at Northwestern University to study the drug, Isradipine, and its possible effects on Parkinson's disease.

Injected neural stem cells reduce Parkinson's symptoms in primates

Primates with severe Parkinson's disease were able to walk, move, and eat better, and had diminished tremors after being injected with human neural stem cells, a research team from Yale, Harvard, the University of Colorado, and the Burnham Institute report in Proceedings of the National Academy of Sciences.
