Study provides understanding of root causes of clinical variability in anxiety disorders

New findings from nonhuman primates suggest that an overactive core circuit in the brain, and its interaction with other specialized circuits, accounts for the variability in symptoms shown by patients with severe anxiety.

Luminex collaborates with Merck to design companion diagnostic device for Alzheimer’s disease

WHITEHOUSE STATION known as MSD outside the United States and Canada, and Luminex Corporation have signed a collaboration and license agreement to develop a companion diagnostic device that will be evaluated to help screen patients for recruitment into Merck's clinical development program for MK-8931, a novel oral beta amyloid precursor protein site cleaving enzyme (BACE) inhibitor and Merck's lead investigational candidate for Alzheimer's disease (AD).

Stress and mental illness: an interview with Professor Akira Sawa

As a psychiatrist I am interested in how stress may play a role in the pathology of adult mental disorders. You may know that most of the major mental illnesses, such as schizophrenia, mood-disorder, substance abuse or even anxiety disorder, become prominent in early adulthood.

PET with 11C-PIB can positively visualize amyloid deposits in the heart

While amyloid imaging may now be most associated with detecting plaques in the brain, it has the potential to change the way cardiac amyloidosis is diagnosed. According to first-of-its-kind research published in the February issue of The Journal of Nuclear Medicine, positron emission tomography (PET) with 11C-PIB can positively visualize amyloid deposits in the heart.

Alzheimer's Association, SNMMI publish appropriate use criteria for brain amyloid imaging with PET

Only recently has it become possible to create high-quality images of the brain plaques characteristic of Alzheimer's disease in living people through positron emission tomography (PET). Even so, questions remain about what can be learned from these PET images and which people should have this test.

UCLA researchers identify abnormal tau proteins associated with sports-related concussions

Sports-related concussions and mild traumatic brain injuries have grabbed headlines in recent months, as the long-term damage they can cause becomes increasingly evident among both current and former athletes. The Centers for Disease Control and Prevention estimates that millions of these injuries occur each year.

18F-FDG PET/CT may become important distant staging modality in patients with breast cancer

New research published in the January issue of The Journal of Nuclear Medicine shows that 18F-fludeoxyglucose (18F-FDG) positron emission tomography (PET)/computed tomography (CT) imaging offers significant prognostic stratification information at initial staging for patients with locally advanced breast cancer. When compared to conventional imaging, 18F-FDG PET/CT more accurately showed lesions in the chest, abdomen and bones in a single session, changing management for more than 50 percent of the patients in the study.

FAC PET identifies liposarcoma tumors that are sensitive to chemotherapy

Liposarcoma, the most common type of sarcoma, is an often lethal form of cancer that develops in fat cells. It is particularly deadly, in part, because the tumors are not consistently visible with positron emission tomography (PET) scans that use a common probe called FDG and because they frequently do not respond to chemotherapy.

Combination of diagnostic tests can predict conversion from MCI to Alzheimer's

A combination of diagnostic tests, including imaging and cerebrospinal fluid biomarkers can improve prediction of conversion from mild cognitive impairment (MCI) to Alzheimer's disease, according to a new study published online in the journal Radiology.
