Late-life depression not linked with increased amyloid deposits in the brain

Depression in elderly people can include symptoms such as memory loss, making it hard to distinguish from the early stages of Alzheimer's disease and other types of dementia.

Innovative approach for identifying new molecules to help track progression of Parkinson's

For many of the 200,000 patients diagnosed with Parkinson's disease in the United States every year, the diagnosis often occurs only after the appearance of severe symptoms such as tremors or speech difficulties.

Molecular imaging probe reveals Alzheimer's-related γ-secretase in rodents, macaques

Scientists at the Massachusetts General Hospital (MGH) have developed a molecular imaging probe to reveal Alzheimer's disease (AD)-related γ-secretase in rodents and macaques with translational potentials in humans.

PET/MRI reduces radiation exposure, improves lesion detectability in select cancers

A single-center observational study of more than 1,000 oncological examinations has demonstrated that positron emission tomography/magnetic resonance imaging (PET/MRI) facilitates cancer staging as well as PET/computed tomography (PET/CT) and improves lesion detectability in select cancers, potentially helping to promote fast, efficient local and whole-body staging in one step.

New nanomedicine is efficient and less aggressive than conventional prostate cancer therapy

Prostate cancer is the most common type of cancer among European men; its incidence surpasses 100 cases per 100,000 people.

Researchers develop new PET imaging agent that spotlights inflammation

Many of the most common diseases -- cancer, diabetes, cardiovascular and lung disease, and even COVID-19 -- have been linked to chronic or excessive inflammation.

NIH provides additional support for large scale study of Alzheimer's disease biomarkers

To meet the pressing need to better understand the prevalence, progression, and clinical impact of Alzheimer's disease among Mexican Americans, the National Institutes of Health has added funding for more biomarker measures, including positron emission tomography imaging, to the ongoing Health and Aging Brain Among Latino Elders Study.

Molecular imaging reveals ASD-related brain differences

People with autism spectrum disorder have lower levels of a protein that regulates the amount of serotonin in the brain, a paper from Karolinska Institutet in Sweden published in the journal Molecular Psychiatry reports.

Sleep may serve as a marker of Alzheimer’s disease risk and progression

What would you do if you knew how long you had until Alzheimer's disease set in? Don't despair. New research from the University of California, Berkeley, suggests one defense against this virulent form of dementia -- for which no treatment currently exists -- is deep, restorative sleep, and plenty of it.

Study shows link between lipid metabolism and onset of psychosis

Changes in blood lipids give an early warning for the development of psychosis in individuals who are at risk. Weight gain displays the same connection. This is shown in a new study at örebro University.

New method can detect small amounts of protein fragment linked to Alzheimer's disease

Researchers at Washington University School of Medicine in St. Louis have developed a technique to detect minute amounts of a protein fragment linked to Alzheimer's disease in the blood.

Simple blood test may be a great advance for people with and at risk for Alzheimer's

A simple blood test for Alzheimer's would be a great advance for individuals with - and at risk for - the disease, families, doctors and researchers.

Discovery could pave way for a blood test to diagnose Alzheimer's before symptoms appear

Two decades or more before symptoms arise, plaques of a sticky protein called amyloid begin forming in the brains of people later diagnosed with Alzheimer's disease.

Gene signature explains why 18F-FDG imaging performs better for PSMA-suppressed prostate cancer patients

Scientists have uncovered the genomic signature to explain why 18F-FDG imaging performs better than PSMA-targeted imaging for prostate cancer patients with low or no expression of the prostate-specific membrane antigen (PSMA).

Research suggests a possible new approach to treating neurodegenerative diseases

Researchers at Vanderbilt University Medical Center have shown for the first time that when one optic nerve in the eye is damaged, as in glaucoma, the opposite optic nerve comes to the rescue by sharing its metabolic energy.

Super-agers found to have increased resistance to tau and amyloid proteins

Super-agers, or individuals whose cognitive skills are above the norm even at an advanced age, have been found to have increased resistance to tau and amyloid proteins, according to research presented at the Society of Nuclear Medicine and Molecular Imaging 2020 Annual Meeting.
