Depression in Parkinson's disease people associated with reduced dopamine synthesis capacity

According to the Parkinson's Disease Foundation, up to 60% of individuals with Parkinson's disease exhibit mild to moderate depression, which is often underdiagnosed. It is unclear whether depression results from having a debilitating disease or reflects a parallel abnormal change in the brain caused by PD pathophysiology.

Neuroscientists honored for research into brain's reward and decision-making systems

Maximum reward, minimum punishment: these are the maxims humans and animals often apply when making decisions. A network of nerve cells in the brain conveys gratification.

Study suggests that human brains are hardwired to empathize with friends, spouses

Perhaps one of the most defining features of humanity is our capacity for empathy - the ability to put ourselves in others' shoes. A new University of Virginia study strongly suggests that we are hardwired to empathize because we closely associate people who are close to us - friends, spouses, lovers - with our very selves.

Identifying bipolarity through MRI's proves successful in initial results

What are some of the most troubling numbers in mental health? Six to 10 -- the number of years it can take to properly diagnose a mental health condition. Dr. Elizabeth Osuch, a Researcher at Lawson Health Research Institute and a Psychiatrist at London Health Sciences Centre and the Department of Psychiatry at Western University, is helping to end misdiagnosis by looking for a 'biomarker' in the brain that will help diagnose and treat two commonly misdiagnosed disorders.

Researchers identify structural anomalies that may increase risk of ADHD in premature newborns

In the first study of its kind, Natasha Leporé, PhD, and colleagues have pinpointed structural anomalies in the developing brain that may increase the risk of cognitive disabilities, such as frontal executive dysfunction and attention deficit hyperactivity disorder, in premature newborns.

Insight linked to gray matter volume in FEP patients

Results from an Irish study show that poor insight is associated with increased gray matter volume in subcortical and frontotemporal brain regions among patients with first-episode psychosis, but not in those with chronic schizophrenia.

New study on motor chunking

You pick up your cell phone and dial the new number of a friend. Ten numbers. One. Number. At. A. Time. Because you haven't actually typed the number before, your brain handles each button press separately, as a sequence of distinct movements.

Ventral striatum drives motivation during cognitive and motor actions

A team coordinated by Mathias Pessiglione, Inserm researcher at the -Centre de recherche en neurosciences de la Piti- Salp-tri-re- (Inserm/UPMC-Universit- Pierre and Marie Curie/CNRS) have identified the part of the brain driving motivation during actions that combine physical and mental effort: the ventral striatum.

Addiction could be a legacy from parents: Study

Researchers have found that like other inherited traits – addiction could be a legacy from parents. A child of drug-addicted parents is eight times more likely to become an addict than a child growing up in a drug-free home. However in families whose very brains seem primed for addiction, some children still go on to lead productive lives free of drugs, according to new research.
