Alzheimer's disease has proven to be a difficult enemy to defeat. After all, aging is the No. 1 risk factor for the disorder, and there's no stopping that. Most researchers believe the disease is caused by one of two proteins, one called tau, the other beta-amyloid. As we age, most scientists say, these proteins either disrupt signaling between neurons or simply kill them. Now, a new UCLA study suggests a third possible cause: iron accumulation.
Completely Paralyzed Man Voluntarily Moves His Legs, UCLA Scientists Report
A 39-year-old man who had had been completely paralyzed for four years was able to voluntarily control his leg muscles and take thousands of steps in a "robotic exoskeleton" device during five days of training -- and for two weeks afterward -- a team of UCLA scientists reports this week. This is the first time that a person with chronic, complete paralysis has regained enough voluntary control to actively work with a robotic device designed to enhance mobility.
Jupiter-like Planet Discovered Outside Our Solar System
A planet 100 light-years away that resembles a young Jupiter has been discovered by an international team of astronomers that includes six UCLA scientists. The discovery is reported Aug. 13 in the online edition of the journal Science.
Kids, Teens Win When Mental Health Providers Team with Pediatricians, Family Doctors
For the past decade, cutting-edge health care providers and researchers have increasingly pushed to integrate care for mental health and substance use problems within primary medical care for children and adolescents. Their hope is that children and teens who suffer from mental and behavioral disorders would fare better if their pediatricians or family doctors took an active role in linking them with mental health care, particularly when these doctors team up with mental health clinicians to help meet the needs of their young
How to Convince Vaccine Skeptics - And How Not To
Many people who are skeptical about vaccinating their children can be convinced to do so, but only if the argument is presented in a certain way, a team of psychologists from UCLA and the University of Illinois at Urbana-Champaign reported today. The research appears in the online early edition of the journal Proceedings of the National Academy of Sciences.
Young Adults with Autism Show Improved Social Function Following UCLA Skills Program
Researchers at the Semel Institute for Neuroscience and Human Behavior at UCLA have found that a social skills program for high-functioning young adults with autism spectrum disorder significantly improved the participants' ability to engage with their peers.
Non-surgical Approach Helps People with Paralysis Voluntarily Move Their Legs
In a study conducted at UCLA, five men who had been completely paralyzed were able to move their legs in a rhythmic motion thanks to a new, noninvasive procedure that stimulates the spinal cord. It is believed to be the first time voluntary leg movements have ever been relearned in completely paralyzed patients without surgery. The results are reported in the Journal of Neurotrauma.
A Way to Predict Whether Children with DiGeorge Syndrome Will Develop Autism Or Psychosis
Doctors and researchers have long known that children who are missing about 60 genes on a certain chromosome are at a significantly elevated risk for developing either a disorder on the autism spectrum or psychosis -- that is, any mental disorder characterized by delusions and hallucinations, including schizophrenia. But there has been no way to predict which child with the abnormality might be at risk for which disorder.
Oceans Slowed Global Temperature Rise, Scientists Report
A new study of ocean temperature measurements shows that in recent years, extra heat from greenhouse gases has been trapped in the subsurface waters of the Pacific and Indian oceans, thus accounting for the slowdown in the global surface temperature increase observed during the past decade, researchers say.
