Efforts to develop a treatment that stalls the memory-robbing devastation of Alzheimer’s disease have so far been unsuccessful, but scientists are making strides in another important area: the development of better tests to tell who has the condition. Their aim is to develop more accurate, cheaper and less invasive tests to detect the biological markers […]

Just one night of poor sleep can boost Alzheimer’s proteins (Links to an external site)

How well, not how much, people sleep may affect Alzheimer’s disease risk. Healthy adults built up Alzheimer’s-associated proteins in their cerebral spinal fluid when prevented from getting slow-wave sleep, the deepest stage of sleep, researchers report July 10 in Brain. Just one night of deep-sleep disruption was enough to increase the amount of amyloid-beta, a protein that […]

How Seniors Are Driving Safer, Driving Longer (Links to an external site)

Americans love to drive. More than 75 percent of adults carry a driver’s license, including 40 million who are 65 and older. But driving is more than just a passion or a pastime: It’s a lifeline. Studies show that giving up driving increases a person’s mortality risk and makes seniors more likely to land in […]

Antibody Makes Alzheimer’s Protein Detectable in Blood (Links to an external site)

Age can bring moments of forgetfulness. It can also bring concern that the forgetfulness might be a sign of early Alzheimer’s disease. For those who decide to have it checked out, doctors are likely to administer brief memory exams to assess the situation, and medical tests to search for causes of memory loss. Brain imaging […]

Antibody helps detect protein implicated in Alzheimer’s, other diseases (Links to an external site)

Researchers use mouse brains (above) to study ways to measure the brain protein tau, which plays a role in neurodegenerative diseases such as Alzheimer's. A team led by scientists at Washington University School of Medicine in St. Louis has found a way to measure tau levels in the blood. The study, in mice and a small group of people, could be the first step toward a noninvasive test for tau.

Damaging tangles of the protein tau dot the brains of people with Alzheimer’s and many other neurodegenerative diseases, including chronic traumatic encephalopathy, which plagues professional boxers and football players. Such tau-based diseases can lead to memory loss, confusion and, in some, aggressive behavior. But there is no easy way to determine whether people’s symptoms are linked to […]

Feb. 8 (UPI) — Research from the National Institutes of Health, or NIH, suggests the potential to prevent or reverse brain damage caused by tau protein in dementia patients. The study of mice and monkeys showed that tau antisense oligonucleotides, which are genetically engineered to block a cell’s production of tau, have the potential to treat […]

Drug compound halts Alzheimer’s-related damage in mice

Tau oligos

In some people, the brain protein tau collects into toxic tangles that damage brain cells and contribute to diseases such as Alzheimer’s. Researchers at Washington University School of Medicine in St. Louis have found a drug that can lower tau levels and prevent some neurological damage. In neurons that contain the drug (above, in red) […]

Welders showed increased risk of Parkinson-like symptoms in study

Welders are in danger of developing symptoms similar to those of Parkinson’s disease, according to a new study that suggests exposure to fumes containing manganese makes things worse. Welding has been linked in previous research to a higher risk for parkinsonism. The term refers to a group of disorders that causes movement problems that mimic […]
