Researchers Find Gene That Protects Against Dementia in High-Risk Individuals

Neuroscientists had assumed that a mutation in the progranulin gene, which makes the progranulin protein and supports brain neurons, was sufficient to produce a kind of dementia known as frontotemporal lobar degeneration (FTLD). But now an international team of scientists led by researchers at Mayo Clinic’s campus in Florida have found another genetic factor they say appears to protect against the disorder in progranulin mutation carriers.

Researchers Study Best Way to Help African-American Dementia Caregivers

With a rapidly expanding population of elders, the number of dementia caregivers in Florida is increasing exponentially. According to the Alzheimer’s Association, nearly 10 million caregivers provide unpaid care to people with Alzheimer’s disease. Finding the best way to support caregivers, especially with fewer state resources available, is one focus of ongoing research at Mayo Clinic in Florida.

MRI Scans Reveal Brain Changes in People at Genetic Risk for Alzheimer’s

People with a known, high risk for Alzheimer’s disease develop abnormal brain function even before the appearance of telltale, amyloid plaques that are characteristic of Alzheimer’s disease, according to a new study from researchers at Washington University School of Medicine in St. Louis. The findings suggest that a gene variant affects brain function long before the brain begins accumulating the amyloid that will eventually lead to dementia.

Alzheimer's Patients Clear Less of Plaque Component

Neurologists have answered one of the most important questions about Alzheimer's: Do rising brain levels of a plaque-forming substance mean patients are making more of it or that they can no longer clear it as effectively? Researchers found clearance rates decline in Alzheimer's patients.

Ginseng Might Boost Brain Power, but Evidence Is Weak

Many people believe that the popular herb ginseng can improve thinking ability and prevent or even treat dementia. However, a comprehensive review of research failed to find convincing evidence of these benefits.

New Insight Into the Cause of Common Dementia Found by Researchers

Researchers at the Mayo Clinic campus in Florida have found a clue as to how some people develop a form of dementia that affects the brain areas associated with personality, behavior, and language.

Modulating a Protein in the Brain Could Help Control Alzheimer’s Disease

A protein known to exist in the brain for more than 30 years has been found to play a regulatory role in the formation of the amyloid beta in the brain, the major component of plaques implicated in the development of Alzheimer’s disease

Alzheimer's Accelerated by a Chemical in Cigarette Smoke, Auto Exhaust and French Fries

There is growing evidence that exposure to a group of chemicals known as type-2 alkenes -- which are found in the smoke inhaled from cigarettes, the exhaust of automobiles and even in French fries – can increase the chances of developing Alzheimer’s disease and other neurological conditions such as Parkinson’s disease. Can Curry, Wine and Apple Skins Offer an Antidote?

MRI Scans Show Structural Brain Changes in People at Risk for Alzheimer’s Disease

New results from a study by neuroscientists at Rush University Medical Center suggest that people at risk of developing Alzheimer’s disease exhibit a specific structural change in the brain that can be visualized by brain imaging. The findings may help identify those who would most benefit from early intervention.
