New imaging compound could help identify signs of early-stage Alzheimer's disease

By the time unambiguous signs of memory loss and cognitive decline appear in people with Alzheimer's disease, their brains already are significantly damaged, dotted with clumps of a destructive protein known as amyloid beta.

PET imaging can accurately identify difficult-to-diagnose cardiac amyloidosis

Reston, Virginia - Researchers at Princess Alexandra Hospital, Brisbane, Australia, have demonstrated that cardiac amyloidosis (abnormal deposits of proteins in the heart), which is notoriously difficult to diagnose, can be visualized noninvasively with positron emission tomography (PET) using the radiotracer fluorine-18 (F-18)-florbetaben.

Researchers find altered brain activity in specific brain regions of patients with insomnia

Specific brain regions, including those involved in awareness of self and tendency to ruminate, show altered activity in patients with insomnia when compared to good sleepers, according to a new study by researchers at the University of Pittsburgh School of Medicine published this week in the journal SLEEP.

Researchers find link between dopamine neurotransmitter system and facial recognition

In a recent study, researchers at Center for BrainHealth, working in collaboration with colleagues in Sweden, have revealed a link between the dopamine neurotransmitter system in the brain and an individual's ability to recognize faces.

Experimental PET tracer can diagnose concussion-related brain degeneration in living person

An experimental positron emission tomography (PET) tracer can effectively diagnose concussion-related brain degeneration while a person is still alive, according to a proof-of-concept study conducted at the Icahn School of Medicine at Mount Sinai and published September 27 in the journal Translational Psychiatry.

PACIFIC study may offer guidance to choose from number of non-invasive coronary artery imaging

For patients presenting for the first time with suspected coronary artery disease (CAD) clinicians have had a number of non-invasive diagnostic tests to choose from, but little evidence for which is best.

New research discovers how opposite-sex hormonal therapy influences the brain

Women and men often show marked differences as regards mental illnesses. In order to learn more about this phenomenon, a project supported by the Austrian Science Fund FWF explored how opposite-sex hormonal therapy applied to transgender individuals influences the brain.

Researchers find causal link between senescent cells and age-related osteoarthritis

Researchers at Mayo Clinic have reported a causal link between senescent cells — cells that accumulate with age and contribute to frailty and disease — and osteoarthritis in mice.

Scientists use new non-invasive PET scanning method to monitor hippocampal neurogenesis

Scientists from the RIKEN Center for Life Science Technology in Japan have used a new non-invasive PET scanning technique to obtain images of neuron proliferation in the subventricular zone and subgranular zone of the hippocampal dentate gyrus. Neurogenesis in the hippocampal dentate gyrus is known to be particularly affected by depression.

Waterloo researchers unveil new screening tool and data at 2016 AAIC

Two studies involving University of Waterloo researchers presented this week at the 2016 Alzheimer's Association International Conference (AAIC) in Toronto highlight a new diagnostic tool that can identify Alzheimer's disease long before the onset of symptoms as well as the increasing prevalence of Alzheimer's disease in Ontario.

DPUK brings organisations together to tackle dementia across the UK

Dementia, is an overall term that describes a wide range of symptoms that includes memory loss and difficulties with thinking, is caused when the brain cells degenerate and die more quickly than they would as part of the normal ageing process.

Spinach-like nanoparticle juice may improve doctor's ability to examine gastrointestinal tract

The pigment that gives spinach and other plants their verdant color may improve doctors' ability to examine the human gastrointestinal tract.

New methods to examine the brain and spinal fluid could lead to early detection of Alzheimer's disease

New methods to examine the brain and spinal fluid heighten the chance of early diagnosis of Alzheimer's disease. Results from a large European study, led by researchers at the Karolinska Institutet, are now published in the medical journal BRAIN.

Hippocampal inflammation linked to depressive symptoms in patients with multiple sclerosis

Patients with multiple sclerosis have higher rates of depression than the general population, including people with other life-long disabling diseases. Symptoms of multiple sclerosis arise from an abnormal response of the body's immune system.

Brain's reward system in obese people operates differently in response to food and dopamine

As young people reach adulthood, their preferences for sweet foods typically decline. But for people with obesity, new research suggests that the drop-off may not be as steep and that the brain's reward system operates differently in obese people than in thinner people, which may play a role in this phenomenon.

CT-derived SULps can improve accuracy of PET imaging in advanced cancer patients

Cancer patients often experience significant fluctuations in weight and lean body mass (LBM). Neglecting to account for these changes can prevent clinicians from obtaining precise data from molecular imaging, but a new method of measuring LBM takes changes in individual body composition into account for better staging of disease and therapy monitoring, say researchers at the 2016 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging.

FDG-PET imaging tracks ability of atezolizumab to bolster immunity against NSCLC

Non-small cell lung cancers have a collective reputation for not responding very well to chemotherapy. Researchers at the 2016 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging (SNMMI) are presenting a means of evaluating an immunotherapy that fights off NSCLC by strengthening a patient's own immune system.
