Of Mice and Flies: A Cutting-Edge Method for Detecting Neurodegenerative Disease Targets
Thursday, May 16, 2013
Studying neurodegenerative diseases can be like investigating a crime. Scientists inspect damaged nervous tissue, or “the scene”, for suspicious molecules and then work backwards to explain how the suspects may have killed nerve cells. Recently two research groups, one in the United States and the other in the United Kingdom, collaborated to develop a new way to quickly round up many more suspects and test their “alibis”. Their results may lead to more effective treatments for Alzheimer’s disease, Parkinson’s disease and a variety of other neurodegenerative disorders.

Scientists have sequenced the gene responsible for early-onset torsion dystonia and have found a new class of proteins that may provide insight into all of the dystonia disorders. The discovery of the gene will make diagnosis of early-onset torsion dystonia easier and allow scientists to investigate other factors that might contribute to the disease.

Scientists Gain New Understanding of CNS Stem Cells: Findings May Lead to Improved Treatments for Parkinson's Disease, Other Disorders
Thursday, Apr 3, 1997
For decades, scientists believed that the adult central nervous system could not repair itself, in part because it lacked fundamental 'stem cells', mother cells that can divide to form other kinds of cells. A series of findings has now shown that stem cells are present in the adult brain and spinal cord, and that they can be grown in culture and directed to act in much the same way as fetal stem cells. These findings provide new hope for people with Parkinson's disease, spinal cord injury, and a host of other disorders.

Scientists Locate Parkinson's Gene
Thursday, Nov 14, 1996
For the first time, scientists have pinpointed the location of a gene they believe is responsible for some cases of Parkinson's disease. Their discovery provides strong evidence that a genetic alteration is capable of causing the disease. The study, published in the November 15 issue of Science,1 sheds light on the mysterious origins of this devastating neurological disease that affects about 500,000 Americans.

New Drug Prolongs Symptom Relief in Parkinson's Disease
Thursday, Apr 29, 1993
A new drug, when added to standard treatment for Parkinson's disease, prolongs relief of symptoms by more than 60 percent, report scientists from the National Institute of Neurological Disorders and Stroke (NINDS). In announcing their findings today at the annual meeting of the American Academy of Neurology in New York,* scientists said that the drug, called R0 40-7592, could help overcome drawbacks of current drug treatment.

NINDS Hails Discovery of Gene for Familial ALS
Wednesday, Mar 3, 1993
Officials at the National Institute of Neurological Disorders and Stroke (NINDS) hailed the identification of a gene associated with the familial form of ALS (Lou Gehrig's disease). "This discovery is extremely important because it marks the first identification of a specific gene for a neurodegenerative disease of adult life," said Carl M. Leventhal, M.D., director of the NINDS program that contributed to support for the research reported in the March 3 issue of Nature*. "It also suggests a likely mechanism for the damage to nerve cells in familial ALS and, possibly, other brain disorders."

DATATOP Study Confirms Deprenyl's Efficacy in Fighting the Progression of Parkinson's Disease
Wednesday, Jan 20, 1993
Scientists announced today in the January 21 New England Journal of Medicine the results of a broad, long-term study on the effects of deprenyl and tocopherol (a form of vitamin E) on the progression of early Parkinson's disease. The investigators, who comprise a group known as the Parkinson's Study Group, confirmed that deprenyl is effective in slowing the early progression of Parkinson's disease and delaying the need for initiation of therapy with the drug levodopa. The latest results of the study showed, however, that the beneficial effects of deprenyl were not as lasting in fighting Parkinson's disease as the investigators had anticipated when evaluating the preliminary results in 1989. The clinical trials also showed no evidence that tocopherol was useful in Parkinson's disease.

Study Detects Brain Virus in HIV-Positive Patients
Tuesday, May 5, 1992
Scientists at the National Institute of Neurological Disorders and Stroke (NINDS) have identified a potentially fatal virus in the bloodstream in half of a small group of HIV-positive patients without neurological symptoms, they announced today at the annual meeting of the American Academy of Neurology in San Diego.

Newly developed electrode records neurotransmitter release from a single cell
Monday, Jun 17, 1991
Scientists supported by the National Institute of Neurological Disorders and Stroke (NINDS) have invented a tiny, ultra-sensitive electrode that can record, for the first time, the millionths-of-a-second-long burst of catecholamine molecules as they erupt from the surface of a single cell. Catecholamines are used by some cells as neurotransmitters, or molecules that allow nerve cells to communicate between themselves and with other kinds of cells.

Mounting knowledge of Parkinson's disease leads to new treatment theories
Thursday, Dec 6, 1990
Animal studies have revealed new knowledge of brain chemistry in Parkinson's disease and suggest new treatment approaches, according to results published in the December 7, 1990 issue of Science.*
