Brain Research: New therapy slows spread of deadly brain tumor cells ♦ Insulin resistance increases risk for Alzheimer's disease ♦ biomarkers key to early intervention in Alzheimer's diseas

New therapy slows spread of deadly brain tumor cells The rapid spread of a common and deadly brain tumor has been slowed down significantly in a mouse model by cutting off the way some cancer cells communicate.
Insulin resistance increases risk for Alzheimer's disease A strong association between insulin resistance and memory function decline has been found by researchers who suggest that this link increases the risk for Alzheimer's disease.
Low-dose lithium reduces side effects from most common treatment for Parkinson's disease Low-dose lithium reduced involuntary motor movements -- the troubling side effect of the medication most commonly used to treat Parkinson's disease (PD) -- in a mouse model of the condition that is diagnosed in about 60,000 Americans each year. The third in a series of studies from involving PD and low-dose lithium, the results add to mounting evidence that low-doses of the psychotropic drug could benefit patients suffering from the incurable, degenerative condition.
Identifying bio markers key to early intervention in Alzheimer's disease Researchers are looking for bio markers that might serve as an early warning system for Alzheimer's disease. The process is not without complications, but these scientists possess a collective “Rosie the Riveter” spirit.
National study of deep brain stimulation for depression fails to demonstrate efficacy Depression is a leading cause of disability worldwide, and treatment-resistant symptoms of depression have a terrible personal and societal cost. They can devastate lives, careers, and families. Some severely ill patients may be unable to attend to even the basic elements of self-care, while others attempt or complete suicide. Now researchers report the results of the first large-scale, randomized, sham-controlled trial of deep brain stimulation treatment for treatment-resistant symptoms of depression.
