UCLA Study Suggests Iron Is at Core of Alzheimer's Disease

Published: August 20, 2013.
Released by University of California - Los Angeles  

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.

Researchers Help Create 'Gold Standard' Method for Measuring an Early Sign of Alzheimer's
After six years of painstaking research, a UCLA-led team has validated the first standardized protocol for measuring one of the earliest signs of Alzheimer's disease -- the atrophy of the part of the brain known as the hippocampus.

UCLA Statistician Helps Resolve Dispute About How Gene Expression Is Controlled
The differences between different tissues, such as brain and muscle, and between healthy and unhealthy human cells are largely defined by changes in the abundance of proteins in the cells. Transcription -- the process that governs the flow of genetic information from DNA to RNA -- was long believed to play the dominant role in determining the quantity of proteins in a cell. But over the past decade, many studies have claimed that in animals, differences in the rate at which RNA is…

People with Anorexia And Body Dysmorphic Disorder Have Similar Brain Anomalies
People with anorexia nervosa and with body dysmorphic disorder have similar abnormalities in their brains that affect their ability to process visual information, a new UCLA study reveals. People with anorexia have such an intense fear of gaining weight that they starve themselves even when they are dangerously thin. Body dysmorphic disorder is a psychiatric condition characterized by an obsessive preoccupation with a perceived flaw in physical appearance.
