Guidelines for brain amyloid imaging in Alzheimer’s

Guidelines for brain amyloid imaging in Alzheimer’s

Jan. 28, 2013 — Only recently has it become possible to create high-quality images of the brain plaques characteristic of Alzheimer’s disease in living people through positron emission tomography (PET). Even so, questions remain about what can be learned from these PET images and which people should have this test. Continue reading

Science needs a second opinion: Researchers find flaws in study of patients in ‘vegetative state’

Jan. 24, 2013 — A team of researchers led by Weill Cornell Medical College is calling into question the published statistics, methods and findings of a highly publicized research study that claimed bedside electroencephalography (EEG) identified evidence of awareness in three patients diagnosed to be in a vegetative state. The new reanalysis study led by Weill Cornell neurologists Drs Continue reading

Chance finding reveals new control on blood vessels in developing brain

Jan. 24, 2013 — Zhen Huang freely admits he was not interested in blood vessels four years ago when he was studying brain development in a fetal mouse. Instead, he wanted to see how changing a particular gene in brain cells called glia would affect the growth of neurons Continue reading

Right target, but missing the bulls-eye for Alzheimer’s

Right target, but missing the bulls-eye for Alzheimer’s

Jan. 23, 2013 — Alzheimer’s disease is the most common cause of late-life dementia. The disorder is thought to be caused by a protein known as the amyloid-beta protein, or Abeta, which clumps together in the brain, forming plaques that are thought to destroy neurons. Continue reading

Less tau reduces seizures and sudden death in severe epilepsy

Less tau reduces seizures and sudden death in severe epilepsy

Jan. 22, 2013 — Deleting or reducing expression of a gene that carries the code for tau, a protein associated with Alzheimer’s disease, can prevent seizures in a severe type of epilepsy linked to sudden death, said researchers at Baylor College of Medicine and the Mayo Clinic in Jacksonville, Fla., in a report in the current issue of the Journal of Neuroscience .
