New genetic clue to Parkinson's disease

Researchers at Rhode Island Hospital and The Warren Alpert Medical School of Brown University have discovered a gene that could hold the key to developing new treatments for Parkinson's disease – a progressive and often debilitating movement disorder that affects as many as one million Americans.

Smell impairment can precede the development of Parkinson's disease in men

Impaired sense of smell occurs in the earliest stages of Parkinson's disease (PD) and there is mounting evidence that it may precede motor symptoms by several years, although no large-scale studies had confirmed this.

Study shows Parkinson's disease drug dopamine might work in cancer patients

A study published in the March 13 online issue of The Journal of Clinical Investigation shows that dopamine, a drug currently used to treat Parkinson's disease and other illnesses, also might work in cancer patients.

Stem cell funding for Parkinson’s disease

The Parkinson's Disease Society (PD) has announced funding of £170k to the University of Bristol for research into how to make stem cells produce dopamine and live longer after they have been transplanted into animals.

New insight into the fundamentals of Parkinson's disease

A single change in a protein may play a role in whether someone develops Parkinson's disease, say University of Florida Genetics Institute researchers writing in a recent issue of the Proceedings of the National Academy of Sciences.

Risk factors for Parkinson's disease focus of new research

A new study demonstrates that high levels of MAO-B, an enzyme that regulates nerve activity in the brain, cause Parkinson's-like symptoms in mice genetically engineered to overexpress the protein.

New Parkinson's disease research points to serotonin

For most people with Parkinson's disease, the only relief from the tremors, rigidity and impaired movement associated with the progressive loss of their motor skills is a drug called L-DOPA. But as the disease progresses, L-DOPA can cause prominent side effects that counteract its effectiveness.

UCLA study questions diagnosis, medical treatment of ADHD

A new UCLA study shows that only about half of children diagnosed with attention-deficit hyperactivity disorder, or ADHD, exhibit the cognitive defects commonly associated with the condition.

Study supports role of a dopamine related gene in the onset of depression

Depression is one of the most common forms of psychopathology. According to diathesis-stress theories of depression, genetic liability interacts with negative life experiences to cause depression.

Brain processes aggression as a reward

New research from Vanderbilt University shows for the first time that the brain processes aggression as a reward - much like sex, food and drugs - offering insights into our propensity to fight and our fascination with violent sports like boxing and football.
