Withdrawn experimental drug found to reverse Parkinson's brain damage

Neuroscientists at Frenchay hospital in Bristol have discovered that an experimental drug for Parkinson's disease has been shown to trigger new nerve growth in the brain, the first time any treatment has been found to reverse the brain damage caused by the condition.

Experimental treatment regrows nerve fibres in patient suffering Parkinson's disease

Analysis of the brain of a patient suffering from Parkinson’s Disease has shown that the experimental treatment he received caused regrowth of the nerve fibres that are lost in this disease. The findings are reported in the July issue of Nature Medicine.

Circadian clock gene also plays pivotal role in drug addiction

The gene that regulates the body's main biological clocks also may play a pivotal role in drug addiction, researchers at UT Southwestern Medical Center have found.

New dopamine transporter gene findings may be relevant for substance abuse, tobacco smoking, and ADHD

Confirming findings in a previous study, Yale researchers observed an altered availability of the dopamine transporter in healthy persons with a genetic variation linked to substance abuse and attention deficit hyperactivity disorder (ADHD).

A protein found naturally in the brain may protect against Parkinson's disease

The findings also may lead to an improved understanding of a disorder called early-onset torsion dystonia.

University of Exeter researchers discover a stroll could help break your smoking habit

Researchers at the University of Exeter have found a new way to help kick the smoking habit - a quick stroll around the block. They examined the effects of a one mile walk on 15 smokers, who hadn't had a puff for 15 hours.

Those old crooners were right, love really can make you crazy

According to scientists brain images show that falling in love can look for all the world like mental illness with a mixture of mania, dementia and obsession that cuts people off from friends and family prompting uncharacteristic behavior which could almost be mistaken for psychosis.

Basic brain mechanism that causes drug-seeking behavior

In studies with rats, researchers have distinguished a burst of the brain chemical dopamine from a reward-related brain region that is associated with anticipating the delivery of cocaine. The finding, publishing in the May 19 issue of Neuron, reveals the brain signal that likely underlies the fundamental motivation to obtain such drugs, said the scientists.

Walking can cut craving for a cigarette

New research by scientists at Exeter University has shown that going for a walk can help smokers break the habit.

Parkinson's drug Mirapex accused of causing gambling addiction

A drug prescribed to millions of patients in the U.S. as a treatment for Parkinson's disease and other conditions, has allegedly turned some patients into gambling addicts.

Clues about how alcoholic behavior is “switched” on

As part of an ongoing effort to understand the biochemical basis of alcohol abuse, scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have published two studies on how modulating receptors for dopamine - a chemical “signaler” in the brain’s reward circuits - affects drinking behavior in mice and rats.

Gene may boost schizophrenia risk

Clues about how a suspect version of a gene may slightly increase risk for schizophrenia are emerging from a brain imaging study by the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH). The gene variant produced a telltale pattern of activity linked to production of a key brain messenger chemical.

Brain-injury rehabilitation depends on acetylcholine circuitry

The ability of the brain to recover from such injury as stroke or trauma depends on a particular circuitry of neurons that "talk" to one another using the brain chemical acetylcholine, researchers led by James Conner and Mark Tuszynski in the Neural repair Group at UCSD have discovered.

Novel human kidney protein called renalase that regulates both heart contraction and blood pressure

Researchers at Yale School of Medicine and the VA Connecticut Healthcare System in West Haven identified a novel human kidney protein called renalase that regulates both heart contraction and blood pressure; it is a strong candidate for easily administered treatment of advanced kidney and cardiovascular disease.

Findings could lead to improved treatments for schizophrenics, amphetamine abusers

An Oregon Health & Science University researcher is among an international team closing in on why many people with schizophrenia and other psychotic disorders are "supersensitive" to the powerful neurotransmitter dopamine.

Study may lead to a better understanding of how antidepressants like Prozac work

According to results published in today's issue of the journal Neuron, a study in mice proposes that dopamine and serotonin neurotransmitter systems in the brain occasionally get their signals crossed, causing delays in stabilizing mood.

SSRI antidepressants "hijack" dopamine signaling as well launching serotonin signals

Researchers have discovered that antidepressant drugs such as Prozac not only affect levels of the neurotransmitter serotonin in the brain, but also "hijack" dopamine signaling as well--causing it to launch serotonin signals. Their findings offer new insight into how Prozac and other "selective serotonin uptake inhibitors" (SSRIs) work and how they might cause problems in patients taking them.

Metabolic side effects of antipsychotics are known, but rarely monitored

Psychiatrists are doing a “modest” job of monitoring for weight gain, diabetes and other metabolic problems that may result from use of the newer antipsychotics for schizophrenia, researchers say.
