Penn study suggests dopamine treatments may play role in increasing impulsivity While approximately one in five Parkinson's disease patients experience impulse control disorder symptoms, the disease itself does not increase the risk of gambling, shopping, or other impulsivity symptoms, according to research from the Perelman School of Medicine at the University of Pennsylvania. A new study is the first to show in a large sample that people with untreated Parkinson's were no more likely to...

Scientists at Karolinska Institutet in Sweden have identified two molecules that play an important role in the survival and production of nerve cells in the brain, including nerve cells that produce dopamine. The discovery, which is published in the journal Nature Chemical Biology, may be significant in the long term for the treatment of several diseases, such as Parkinson's disease. The same scientists have previously shown that receptors known as "liver X receptors" or LXR, are necessary...

The causes of learning problems associated with an inherited brain tumor disorder are much more complex than scientists had anticipated, researchers at Washington University School of Medicine in St. Louis report. The disorder, neurofibromatosis 1 (NF1), is among the most common inherited pediatric brain cancer syndromes. Children born with NF1 can develop low-grade brain tumors, but their most common problems are learning and attention difficulties. “While one of our top...

Parkinson's disease is a degenerative disorder of the central nervous system that is characterized by tremors, rigidity, slowness of movement, and difficulty walking. It is caused by loss of the neurons that produce the neurotransmitter dopamine (known as dopaminergic neurons). One of the primary goals in Parkinson's disease research is to develop a replacement for dopaminergic neurons. In this issue of the Journal of Clinical Investigation, researchers led by Takuya Hayashi at the RIKEN...

Last year a clinical trial of L-DOPA -- a mainstay of Parkinson's disease therapy -- was launched for Angelman syndrome, a rare intellectual disorder that shares similar motor symptoms such as tremors and difficulty with balance. The clinical trial is based on a 10-year-old case report showing benefit with the drug, but few studies since have explored the neurological justification for using L-DOPA to treat parkinsonian features in Angelman syndrome. New research from the University of...

redOrbit Staff & Wire Reports — Your Universe Online Some drugs used to treat ADHD could affect the brain's reward system, researchers from the University of Copenhagen have discovered. The findings make it easier to understand how the medicine works and could ultimately lead to improvements in the development of and the dose determination associated with ADHD treatments, they report in the latest edition of the Journal of Neurophysiology. As part of the study, Jakob Kisbye...

Scientists may have discovered why the standard treatment for Parkinson's disease is often effective for only a limited period of time. Their research could lead to a better understanding of many brain disorders, from drug addiction to depression, that share certain signaling molecules involved in modulating brain activity. A team led by Bernardo Sabatini, Takeda Professor of Neurobiology at Harvard Medical School, used mouse models to study dopamine neurons in the striatum, a region of...


Word of the Day
out-herod
  • In the phrase to out-herod Herod, to be more violent than Herod (as represented in the old mystery plays); hence, to exceed in any excess of evil.
Herod refers to 'Herod the Great,' a Roman client king and 'a madman who murdered his own family and a great many rabbis.' According to the OED, the term is 'chiefly with allusion to Shakespeare's use' in Hamlet.
