Evidence links cellular iron deficiency to restless legs syndrome

Iron-deficient cells in the brain are mixing up central nervous system signals to the legs and arms causing the irresistible urges to move and creepy-crawly sensations that characterize restless legs syndrome (RLS), a Penn State College of Medicine study reports.

Exercise protects brain cells affected by Parkinson's

In an animal model of Parkinson's, exercise prevents degeneration of nerve cells that are normally impaired or destroyed by the disease, according to University of Pittsburgh researchers.

Gene mutation causes Parkinson's disease in some families

An international research team, led by scientists at the National Institute on Aging (NIA), has discovered a gene, which when mutated, causes Parkinson's disease in some families.

Researchers have found two areas of the brain that appear to compete for control over behavior

You walk into a room and spy a plate of gooey doughnuts dripping with chocolate frosting. But wait: You were saving your sweets allotment for a party later today. If it feels like one part of your brain is battling another, it probably is, according to a newly published study.

Dietary iron imbalances increase the odds of developing Parkinson's disease

You might want to toss those iron-fortified vitamins, because absent a diagnosed deficiency too much of a good thing can be bad.

Cocaine addicts experience a decrease in D2 receptors affecting brain regions involved with movement, as well as motivation

A new study builds on previous research showing that cocaine-addicted people have a low expression of specific dopamine receptors—D2 receptors—in a portion of the brain called the striatum.

Approval of Abilify (aripiprazole) for the treatment of acute bipolar mania

Bristol-Myers Squibb and Otsuka Pharmaceutical have announced that the U.S. Food and Drug Administration (FDA) has approved Abilify (aripiprazole) for the treatment of acute bipolar mania, including manic and mixed episodes associated with bipolar disorder.

Study to test the effectiveness of anti-depressants in treating symptoms of Parkinson’s disease

While Parkinson’s disease typically brings to mind symptoms such as tremors and slow movement, researchers have found that nearly half of all Parkinson’s patients also suffer from depression. While it might seem natural that someone who has a disease such as Parkinson’s might become depressed, it’s not so simple, says neurologist Irene Richard, M.D., who leads the study.

Discovery of dopamine terminal injury in brains of people with HIV dementia

Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have discovered a key mechanism in the brains of people with human immunodeficiency virus (HIV) dementia.

First indication that Parkinson’s disease can be caused by a defect in a protein

The findings of Finnish scientists with their multinational collaborators shed light to the mechanisms of Parkinson’s disease and early menopause.

Researchers have identified a possible cause of an inherited form of Parkinson's disease

Columbia University Medical Center and Albert Einstein College of Medicine researchers have identified a possible cause of an inherited form of Parkinson's disease, which may be related to more common forms of the disease.

Investigating how young adults with attention deficit hyperactivity disorder process sound

Mary-Claire Hanlon, a Psychology Honours student at the University of Newcastle under the supervision of Dr Frini Karayanidis and Associate Professor Ulrich Schall, is recruiting participants for the study investigating the role of sound and dopaminergic mechanisms (brain chemicals) in people with ADHD.

Scientists have turned procrastinating primates into workaholics by temporarily suppressing a gene in a brain circuit involved in reward learning

Using a new molecular genetic technique, scientists have turned procrastinating primates into workaholics by temporarily suppressing a gene in a brain circuit involved in reward learning. Without the gene, the monkeys lost their sense of balance between reward and the work required to get it, say researchers at the National Institute of Mental Health .

New screening tool prevents wrong patients from receiving Parkinson's surgery

The allure of a new brain surgery technique to relieve the stiffness and shaking caused by Parkinson’s disease may lead to unnecessary operations, University of Florida researchers say, but a new screening tool they developed could prevent potentially dangerous procedures.

Clinical trial established that two drugs, levodopa and pramipexole, are both viable initial treatments for Parkinson's disease

The four-year clinical trial established that two drugs, levodopa and pramipexole, are both viable initial treatments for Parkinson's disease, a degenerative disorder of the central nervous system.

3 Aug 2004

Researchers have shown that an experimental vaccine can reduce the amount of neurodegeneration in a mouse model for Parkinson's disease

The finding suggests that a similar therapy might eventually be able to slow the devastating course of Parkinson's disease in humans.

Clinical study compares treatments in early Parkinson's disease

University of Tennessee Health Science Center professor and vice chair of the Department of Neurology, Ronald F. Pfeiffer, M.D., has been an investigator with The Parkinson Study Group (PSG), which recently reported four-year results of a major long-term, multi-center clinical trial.

21 Jul 2004

Levodopa and pramipexole appear to be reasonable options as initial therapy for Parkinson disease

An article in the July issue of the Archives of Neurology reports that the drugs levodopa and pramipexole both appear to be reasonable options as initial therapy for Parkinson disease, but they are associated with different efficacy and adverse effects.

Human ability to generate feelings through imagery could be the key to a breakthrough in the treatment of mental health problems

A leading psychologist has claimed that humans’ ability to generate feelings through imagery – as, for instance, becoming sexually aroused through fantasy - could be the key to a breakthrough in the treatment of a range of mental health problems.
