The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Memantine and Alzheimer's disease

Memantine, a drug approved for the treatment of Alzheimer disease, appears safe and effective in patients with moderate to severe cases of the condition, according to a study in the January issue of Archives of Neurology.

Novel way to treat stroke

A joint research effort between researchers at the Burnham Institute for Medical Research in La Jolla, CA, and a team from Japan (Iwate University, Osaka City University, Gifu University, Iwate Medical University) has discovered a novel way to treat stroke and neurodegenerative disorders.

Genetic mutation that protects against HIV increases the risk of West Nile Virus infection

A genetic mutation that protects against HIV increases the risk of developing clinical West Nile Virus infection, according to a new study appearing online on January 9th in The Journal of Experimental Medicine.

New research reveals a protein involved in lifting depression

Paul Greengard, Ph.D.,a Nobel Laureate researcher says that mice deficient in a protein, called p11, display depression-like behaviours, while those with sufficient amounts behave as if they have been treated with antidepressants.

Cerebral Palsy linked to viral infection at birth

A new Australian study has found that exposure to certain viral infections shortly before and after birth, the perinatal period, is associated with cerebral palsy.

Myelin breakdown appears to be key contributor to Alzheimer disease later in life

A new UCLA imaging study shows that age-related breakdown of myelin, the fatty insulation coating the brain's internal wiring, correlates strongly with the presence of a key genetic risk factor for Alzheimer disease.

Women more vulnerable to effects of alcohol use

Although women consume less alcohol than men, they are more susceptible to some of the negative medical consequences of alcohol use, such as cirrhosis of the liver, cardiac disease, and cognitive impairments.

Researchers uncover new toxic mechanism in ALS - Lou Gehrig's disease

Exactly how ALS - Lou Gehrig's disease - damages motor neurons is one of medical science's lingering mysteries. At least six mishaps within cells appear to contribute to the death of the nerves that enable muscle movement, but nothing stands out as the key problem.

New procedure offers hope to patients at high risk for recurrent stroke

Surgeons at NewYork-Presbyterian Hospital/Weill Cornell Medical Center are the first in the New York City metropolitan area to successfully implant into the brain arteries a new stent specifically designed to treat high-risk stroke patients who have not previously responded to medical therapy.

Evidence that the eye has complementary brain-signaling systems at work

A new retinal photoreceptor adjusts its sensitivity in different lighting conditions, according to scientists at Brown University, where the rare eye cells were discovered.

New approaches to the treatment of osteoporosis

Medical researchers at the University of Bonn, working in collaboration with scientists from Israel, the USA and Britain, have identified a previously unknown regulatory mechanism in the process of bone loss. Their findings could open up new approaches to the treatment of osteoporosis.

Scientists develop prototype drug to prevent osteoporosis based on cannabinoids produced by body

Substances produced in the body that act like those found in the cannabis plant help preserve bone density, according to researchers at the Hebrew University of Jerusalem.

Exposure to infections at birth can trigger brain damage and the development of cerebral palsy

Exposure to certain viral infections shortly before and after birth (the perinatal period) is associated with cerebral palsy, finds a study published online by the British Medical Journal.

Astrocytes play a direct role in controlling blood flow in the brain - influencing Alzheimer's

New findings that long-overlooked brain cells play an important role in regulating blood flow in the brain call into question one of the basic assumptions underlying today's most sophisticated brain imaging techniques and could open a new frontier when it comes to understanding Alzheimer's disease.

Researchers discover brain mechanism involved with interpreting visual signals

Researchers from the University of Chicago have uncovered an important mechanism used by the developing brain to pattern nerve connections in the part of the brain that interprets visual signals.

Researchers move closer to understanding the basis of a severe epilepsy and mental retardation

Researchers at the University of California, San Diego (UCSD) School of Medicine took a step closer to understanding the basis of a severe epilepsy and mental retardation syndrome with work published in the January 5, 2006 issue of the journal Neuron.

New pathways linking liver disease to changes in the central nervous system

Liver disease is often associated with "sickness behaviors," such as malaise, listlessness, anorexia, difficulty concentrating, and fatigue. In cholestatic liver diseases (where bile production is impaired) such as primary biliary cirrhosis, fatigue occurs in up to 86 percent of patients.
