Alzheimer’s: Synthetic protein blocks toxic beta-amyloid

Alzheimer’s: Synthetic protein blocks toxic beta-amyloid

Alzheimer’s is a relentless disease in which toxic clusters of beta-amyloid protein collect in brain cells. Now, scientists have designed a synthetic peptide, or small protein, that can block beta-amyloid in its early and most harmful stages. New research may have found a way to stop Alzheimer’s-related brain damage in its early stages. The synthetic […]

More Alzheimer’s Drug Trial Failures: Are Researchers on the Wrong Track?

More Alzheimer’s Drug Trial Failures: Are Researchers on the Wrong Track?

By Dennis ThompsonHealthDay Reporter Latest Alzheimer’s News WEDNESDAY, April 10, 2019 (HealthDay News) — Amyloid beta has long been a prime suspect in Alzheimer’s disease, since abnormal levels of the protein form disruptive plaques between patients’ brain cells. But drug trials aimed at lowering amyloid levels have repeatedly failed to save people’s brains, and some […]

Syncing brain waves may fight age-related memory problems

Syncing brain waves may fight age-related memory problems

Memory can deteriorate naturally, due to age, and even when this process is not related to neurodegenerative conditions, such as Alzheimer’s, it can still affect a person’s quality of life. Now, researchers from Boston University in Massachusetts are exploring ways of fighting age-related memory decline. By resynchronizing brain waves, we could reverse some age-related memory […]

Dementia: Amyloid PET scans can improve diagnosis and care

Dementia: Amyloid PET scans can improve diagnosis and care

PET scans that can detect changes in the brain relating to Alzheimer’s disease could improve the diagnosis and medical care of people with dementia and similar symptoms. An innovative type of brain scan may improve care for people with Alzheimer’s disease, dementia, and other forms of cognitive impairment. Investigators came to this conclusion after analyzing […]

Brain Scans Spot, Track Alzheimer’s

Brain Scans Spot, Track Alzheimer’s

Latest Alzheimer’s News TUESDAY, April 2, 2019 (HealthDay News) — Brain scans can improve diagnosis and management of Alzheimer’s disease, a new study claims. Researchers assessed the use of PET scans to identify Alzheimer’s-related amyloid plaques in the brain. The study included more than 11,000 Medicare beneficiaries with mild thinking impairment or dementia of uncertain […]

Is this a better way to deliver drugs to the brain?

Is this a better way to deliver drugs to the brain?

The blood-brain barrier is a protective layer that surrounds the brain. Its main function is to prevent potentially harmful agents from leaking into this organ. However, it can also stop certain therapeutic drugs from reaching their target. Using ultrasound in new ways could open the door to better treatments for conditions that affect the brain. […]

Only Spoken Words Processed in Newly Discovered Brain Region

Only Spoken Words Processed in Newly Discovered Brain Region

Latest Alzheimer’s News WEDNESDAY, March 27, 2019 (HealthDay News) — A dementia study has led researchers to a brain region that processes spoken, not written, words. Northwestern University researchers worked with four patients who had a rare type of dementia called primary progressive aphasia (PPA), which destroys language. Although able to hear and speak, they […]

The key to brain health: Light but frequent exercise

The key to brain health: Light but frequent exercise

Researchers are finding new evidence that exercise — even low-intensity, casual physical activity — can boost brain health in the short- and long-term. Frequent but leisurely exercise can boost brain health. Evidence that exercise can benefit the brain and help maintain cognitive function — including memory — is accumulating. One study, for instance, suggests that […]
